Mercedes EIS ProblemsWelcome to Sinspeed’s Mercedes-Benz EIS Repair Service. We specialise in repairing and replacing faulty EIS units for Mercedes-Benz vehicles. Our team of experienced technicians have years of experience in diagnosing and repairing EIS units, and we use only the latest diagnostic equipment and software to ensure that your EIS unit is repaired to the highest standard. Furthermore, we extend our service to the testing and repair of the Mercedes-Benz ESL (Electronic Steering Lock) and Key too!

What Is An EIS & How Does It Work?

 

The Electronic Ignition Switch (EIS) is a vital component in the Mercedes-Benz vehicle’s security system. It is responsible for controlling the vehicle’s immobiliser, which prevents the engine from starting without the correct key. The EIS is also responsible for controlling other security features such as the central locking system and the alarm.

The EIS works by communicating with the key through a transponder chip. When the key is inserted into the ignition, the EIS sends a signal to the key, which responds with a unique code. If the code matches the one stored in the EIS, the immobiliser is deactivated, the ESL (Electronic Steering Lock) is disengaged and the engine can be started. If the code does not match, the immobiliser remains active, and the engine will not start.

The EIS is a complex system that requires specialised knowledge and equipment to diagnose and repair. If the EIS is faulty, it can cause a range of issues, including the engine not starting, the central locking system not working, and the alarm not arming or disarming. In such cases, our highly experienced technicians are at hand to extensively test and repair all types of EIS and ESL failures.

Common EIS Problems

Like any other electronic component, the EIS unit is prone to faults and failures. Here are some of the common problems people experience with the Mercedes-Benz EIS unit:

  • Failed Ignition: One of the most common issues with the EIS unit is a failed ignition. This can be caused by a faulty key, a damaged EIS unit, or a problem with the wiring.
  • Key Not Turning: Another common issue is when the key does not turn in the ignition. This can be caused by a worn-out key, a damaged EIS unit, or a problem with the steering lock.
  • Immobiliser Failure: The EIS unit is responsible for controlling the immobiliser, which prevents the car from starting without the correct key. If the immobiliser fails, the car will not start, and the EIS unit may need to be repaired or replaced.
  • Keyless Entry Failure: The EIS unit is also responsible for controlling the keyless entry system. If the keyless entry system fails, the car may not unlock or lock properly, and the EIS unit may need to be repaired or replaced.

In conclusion, the Mercedes-Benz EIS unit is a critical component of the car’s security system, and any faults or failures can cause significant problems. If you experience any of the above issues, it is essential to have your EIS unit checked by a professional.

In some cases, a failing EIS or ESL can be the result of either human error or another fault on the vehicle and some of the most common reasons are listed below:

  • Jump Starting Whilst Key Is Inserted
  • Power Surge
  • Low Battery Voltage

All of the above can cause memory loss to the EIS module and it cannot be repaired or re-flashed using the Mercedes STAR diagnostic system.

Sinspeed EIS Repair Service

Mercedes EIS Fault - Car Won't Start

When it comes to a faulty EIS (Electronic Ignition Switch) unit in a Mercedes-Benz, it is often better to repair it rather than replace it with a new part. This is because the EIS unit is a complex component that is linked to other systems in the car, such as the immobiliser and keyless entry.

Replacing the EIS unit with a new one can be expensive and time-consuming, as it requires reprogramming the keys and other systems. Additionally, a new EIS unit may not be available for direct purchase and special order items can cause further significant delays in getting your vehicle back on the road.

At Sinspeed, we offer a comprehensive EIS repair service that covers all aspects of diagnosing and fixing faults with your EIS unit. Our service includes:

  • Diagnosing the fault with your EIS unit: Our experienced technicians use the latest state-of-the-art technology and leading diagnostic equipment to identify the root cause of the problem with your EIS unit. We’re able to fully communicate with the unit on our test bench, power it up and simulate it as if it were operating on your vehicle, allowing us to confirm faults and identify the root cause of any failures.
  • Repairing or replacing faulty components: We use genuine OE components to repair or replace any faulty parts in your EIS unit, and where possible, uprate components to eliminate any known weaknesses and ensure that it is restored to full working order.
  • Recoding the EIS unit to work with your existing keys: We can recode your EIS unit to work with your existing keys, saving you the cost and hassle of having to replace them or have them reprogrammed.
  • Testing the EIS unit to ensure that it is functioning correctly: After completion of the EIS Repair, we rigorously test your unit to ensure that it is functioning correctly before returning it to you.
  • Lifetime warranty for complete peace of mind: We offer a lifetime warranty on all of our EIS repairs, giving you complete peace of mind that your EIS unit is in safe hands.

EIS Replacement Options

When it comes to the Mercedes EIS, it is a common failing part that can cause a lot of frustration for vehicle owners. While repairing the original part is often the best option, there are times when a replacement may be necessary.

At Sinspeed, we understand the importance of using genuine parts and repairing components whenever possible – not only does it reduce complications on the vehicle but we should all do our part to be carbon-neutral. That’s why we always recommend trying to repair the original EIS before considering a replacement. Not only is this the most cost-effective option, but it also ensures that the vehicle is using the part that was specifically designed for it.

However, there are situations where a replacement may be necessary. In these cases, we offer high-quality replacement parts that are fully compatible with the vehicle. Our team of experts can program the replacement part so that there is no need for any recoding when it is re-installed back on the vehicle. This makes the replacement process quick and easy and ensures that the vehicle is back on the road as soon as possible.

Any replacements offered will be genuine parts that meet and exceed OE specifications. This ensures that the replacement part will perform just as well as the original, and will provide reliable service for years to come. In fact, it will also be covered by the Sinspeed Lifetime Warranty for complete peace of mind.

At Sinspeed, we pride ourselves on our expertise and attention to detail when it comes to EIS repairs. Our technicians have years of experience in working with Mercedes-Benz vehicles, and we use only the latest diagnostic equipment and genuine OE components in our repairs. So if you’re experiencing issues with your EIS unit, get in touch with us today to see how we can help.

Commonly Asked Questions

  • What if it is my ESL or Key that’s faulty – What should I do?
    We always recommend sending all three parts to us so that we can independently test the units and also test them in circuit alongside each other. We can remanufacture all three parts if required and any repaired units are returned with a Lifetime warranty for complete peace of mind.
  • Will Mercedes EIS programming be required?
    No – we backup all the programming data before remanufacturing the units. Our remanufactured units are returned fully plug & play and will self-calibrate when fitted back to the vehicle.
  • Can you offer a Mercedes EIS replacement?
    Certainly – if your unit is for any reason beyond repair, we can offer a replacement unit and program it on our bench so that no further coding is required when fitting to the vehicle.
  • I’ve been told my model of Mercedes does not have an ESL?
    Not all Models are fitted with an ESL, some models are controlled through the auto gearbox system and in such cases we will only require the EIS and ignition Key.
  • Do you have a Mercedes EIS removal guide?
    No – we do not offer any removal / fitting instructions and always recommend that the removal and fitting is carried out by a competent technician.

  17. Kenny Hague 29 February 2020

    Hi
    when using the keyfob to open the car it unlocks and immobiliser turns off but the dash lights do not turn on, when i insert key the steering goes to preset memory and seat also, i can turn the key all the way to start but nothing happens. my car is also equipped with keyless go which still works perfectly, so is this a definite fault in the eis?

  18. Chris Cebula 8 February 2020

    I have a 2005 Mercedes W639 Vito and everything works as it should (central locking, Steering lock,Dash lights etc). The problem is it does not turn the starter motor over and there does not seem to be a live feed going to the starter.

    Could this be the EIS or does the feed come via the ECU.

    Thanks Chris

  35. JOHN LOGAN 3 April 2018

    Hello,
    I have 52 plate c220 diesel. I’ve had problems with the key turning but not cranking the engine. A breakdown company attended and after Hitting the starter motor several times with a iron bar, he said that the starter motor needed cleaning. However, I feel it may be the immobiliser as the starter doesn’t make a clicking Sound when turning the key. Should it be the eIS how long and how much would a repair cost? It wouldn’t crank again this morning until I made several Attempts, including pointing the key at the rear view mirror and pressing twice – this worked the first time it wouldn’t start!
    Regards,
    John.

The keys do not lock or unlock anything, or create any activity at all when inserted in the ignition (EIS).

    I have a W203 c class with the key that will not turn and an esl that is non responsive. I had to replace my clocks as the led section was very dim in the day. From then on it started showing dashes on the mileage then intermittent starting issues, i removed the eis for a quick check and it has never started after that as the key will not turn. Is this something you can look at and at what cost roughly

Ronnie,,

  101. Ivica 14 December 2016

    Hi,
    I have 2007 Viano (v350). The key unlocks the steering every time, the dahsboard lights up, all ACC power is on. But moving to IGN, intermittently ignition ligths are NOT turning on, or turning on with delay, and engine would not turn. Taking the key out, reinserting and waiting for a bit before turning to ignition sometimes works and engine would start.
    Is this related to the EIS? The key appears ok to me, as steering lock unlocks every time…

    Please provide quote if EIS is the culprit.

    Regards,
    Ivica

    Hi I was checking a fuse when whilst the engine was running on a 203 c class I pulled f31 and realised the engine cut out after refitting the fuse the key will no longer turn in the ignition.. I tried to see if anything would turn on and notice that if I put fog lights on the display in the instrument cluster lit up but displayed no milage. Could it be that since pulling f31 the eis and the key fobs rolling code no longer match and if so how would I combat this problem?

  129. Ste Murphy 11 July 2016

    Hi Jason
    I have a similar problem with my merc vito 111cdi 08 plate. The steering lock sticks and the key doesnt turn, Its happened a few times in the past and ive managed to get it started by tapping the motor attached to the steering column and shaking the wheel.
    Its happened again now and im having no luck with it.
    The battery in the fob is fine and this motor starts to click when the key is inserted but nothing else happens.
    Does this sound like a problem you guys can fix as I am running out of options
    Thanks

    1. Julio Hernandez 30 May 2016

      Hey Jason. I’m looking to purchase a w210 with this malfunction. The owner is selling for a fairly decent price. But considering the cost for repair I’m probably be out just as much $$ as if I were to purchase one without mechanical failures. From my understanding the dealership is the only facility able to perform this repair. You say your company can repair the eis for cheaper. Please e mail a price list

    Hi, I have a 2004 C220 CDI Coupe. When I put my key in and turn the ignition on the dash lights illuminate as normal but when I try and start the car, nothing happens. Green Flag said it was possibly an ECU problem. Others have said it is probably a defective EIS barrel.

  166. Ian 22 January 2016

    Hi there.

    Mercedes 180C 2L W203 Auto
    Part number ignition switch:
    EZS W203 286 905 03

    My key fob suddenly stopped working probably after my battery went flat due to the cold wether, I fitted a new battery and few day after it was fitted the key started intermittent not turn + steering lock was intermittently not working the same. The steering lock has completely stopped working when key is inserted and the key will not turn at all, it will not lock/unlock with the key fob or turn in the ignition on but will lock and unlock with the button on the dash. What I am thinking is when the battery has gone flat it has wiped the key code with it if this is the case I can recode both key a work it in doing this will it make it better or worse if there is still information still on the key or in the ignition switch that can be saved. If you can shed any light on the the situation that would be much appreciated.

    Thanks Ian

  167. Imran 17 January 2016

    Hi have a 2007 ML320 and whilst driving the radio sometimes cuts out along with air con. I move the key up and down in the ignition slot which reinstates the radio and air con again. Guess a signal is lost somehow. Ive had random situatiins where the remote key would not open the car and had to enter manually. Do you know what this fault is ? And if so could you quote me please
    Kind regards

    I have a MB B200 (w245) and the ignition key don’t work.
    In my country (Argentina) in the agency of MB tell me that de EZS fault and replace it.
    In my country is very costly replacement and am looking for an alternative to latch it.
    You would do this repair and what would be the cost.
    I certainly owe my parts sending by mail box.

  181. Ralph Taubert 18 November 2015

    Hi,

    Having read some of the issues above, mine sounds pretty similar. I have a 2002 C270. My problems are such that my main key has failed altogether, it is only good for locking and unlocking the car. My spare key works and will start the engine but will only start the electronics after a restart a few minutes later once the car is warm.
    Is this an EIS problem too?

    Thanks,
    Ralph

  182. Mark Blair 18 November 2015

  187. Graham Smethurst 6 November 2015

    Hi, I have been having problems for about 6 months now and own a 2006 MB C200 auto diesel estate and they are:
    Insert key turn the engine which then starts, you then lose all dashboard dials, all steering wheel stalk control (indicators etc) volume controls to the CD player, heater controls, electric mirror controls,central locking, electric Windows,parking censor. The engine runs fine, I then turn the engine off re-insert the key turn engine back on and regain all electrics. This happens possibly once or twice a week. I then swapped over to my spare key and low and behold I have not encountered any failures since. Having spoke and searched You Tube on this issue it has been suggested it could be the EIS module, a local NON MB garage ran a diagnosis and said it was a Terminal 15 fault. The cars battery is in good order. Any ideas please.

  188. John 5 November 2015

    Hi I have very nice old 1998 e 280, the key won’t unlock the steering lock and the Carlson start. I’m under pressure from wife to scrap it. But would like to try a repair.

  191. Paul Fitzmaurice 4 October 2015

    Hi I have an intermittent fault with the start and crank operation of my Merc C220 auto,2009
    as I remove the key I dont always get the zip sound as the system shuts down/starts. When I then try to start it again I get not zip sound and I get no ignition lights and the engine will not crank, all the doors open and lock, the steering fails to lockbut no ignition lights or cranking. I have to disconnect the battery for about five minutes and then the key will work, It’s becoming a real pain – can you rectify this?

  192. rob lamb 27 September 2015

    Hi I have an intermittent fault with the start and crank operation of my Merc c280 est auto,2008

  193. Robert 20 September 2015

    W203 c220 intermittent dash/wiper/dimmer/starting/ignition unlocking issue. Notice rear fuse board seems OK as does front and ECU. Notice rear wheelRch feels damp. If I send u a diagnostic and eis can you repair? How much? How long?

  194. Lorne 15 September 2015

    i should have included the part number for my 02 e-320 ignition switch…..it is 2105450308
    tnx

  195. Lorne 15 September 2015

    My ignition switch will not turn on Mercedes 2002 e-320. According to your info, I probably screwed it up when jump starting the car. What do you need me to send you to get re-programmed? And, what will it cost roughly? I should mention that, even though the key won’t turn, the steering wheel is not locked, so something in the eis told the locking pin to release. I can get various replacement ignition switches with key fobs….used ones are really cheap, but can they be reprogrammed to “fit” my VIN?

  196. jeff 15 September 2015

    hi i have a vito 2004 109 cdi .no power to dash key wont turn i have removed the eis ,as i need the van on the road asap ,if i come to your work place friday can it be checked and if so fixed same day as am in grimsby many thanks jeff

  200. Waleed Islam 26 August 2015

    Hi, I am not certain this is the right solution but anyway, I have a 2001 A170 cdi (facelift) which refuses to start. The car was left standing for a couple of days and when I tried to start it turned over slowly and then died – no sound from the ignition / starter, although all lights still showed. I attempted a jump start with no effect but now noticed a message “start error”. I am unable to take the car for diagnostics and, because it is pre OBD diagnostic socket, have no way to determine the fault. Please advise prices, solutions and locations of required modules. Much thanks. Waleed

  201. Stuart Juggins 21 August 2015

  244. Gaz 31 December 2014

    Hi, I have a 2004 vito. We have had problems with locking and unlocking the van in the cold, the van only unlocks once we heat the key. We are also having issues with the ignition, the key won’t turn and when it does eventually turn it still won’t start – it usually takes 10-15 mins to get it started.

    We have 2 keys and have the problem with both keys, we have also replaced the batteries on the keys.

    Can you help?

    Thanks, Gaz

  245. Craig 22 December 2014

    I purchased a 2008 C350 at auction with a light front damage. The car will not start and the remote does not operate the door locks. The steering is locked but the key does turn. The vehicle had a half dead battery for a while. How do I know if it is a key programming issue or an EIS problem or just the steering lock? Do you repair these parts if shipped from USA?

  246. Fred kendrick 21 December 2014

    01 s55 amg need eis repair

  247. Rick 12 December 2014

    Hi, I have a 2003 vito (115 cdi) I can’t unlock using the remote (main or spare key) and when I put the key in the EIS it simply acts like no key has been inserted, no buzz from steering lock, and won’t allow me to turn the key. This started as an intermittent fault (couple of occasions) and now is permanently stuck like it!

    I have checked fuses (that I can find!) and can’t find any problems there, Central locking still works through the centre console. Lights still work ok… I need my van for work HELP!

    I can easily remove the EIS module, and more than happy to bring it to you instead of posting to help speed things up!

    Can you advise of costs of diagnosis and possible repair costs?

    Thanks

  248. Alan McIvor 2 December 2014

    Hello, We have a 2005 Vito with a faulty EIS. This is the second failure in 5 years since having it replaced and re programmed by MB.
    Obviously we are not impressed ,but cutting to the chase, could you enable a repair if the mudule and key is sent to you only.
    We have confirmed the steering lock is functional as it releases when the key is inserted just the start function has now given up after intermitant failures over the last few weeks.
    Please can you also give an approx turn arround also ex works.
    Many thanks

  249. CHARLES RANDALL 2 December 2014

    I have a 2011 GL 450. The EIS works intermittently the steerin lock never works. Please quote a price on repairing the EIS. Does the inoperative steering lock impact the EIS? What is the typical turn around time for a reconditioned EIS?

  250. john sobol 24 November 2014

    Hi I am looking for a quote to repair my eis. Neither key will turn in the lock can only assume this is an eis problem although the spare key was working for a short period I find it unlikely both keys would fail in such short proximity to each other. If you could give me a rough price for repair that would be great. The car is a w220 3.2 petrol.

  251. shah 7 November 2014

    Jason,
    My 2008 c180 w204 refused to start. both key and spare key have similar effect.

  252. Ronnie Oyula 25 October 2014

    My wife’s 2007 c350 w204 refused to start. both key and spare key have similar effect. The key turns in the ignition but nothing happens. Locked gear and steering.

  257. Inam 8 October 2014

    Hey I have a 2003 s430 w220 in Canada and when the eis is cold it does not start unless I use a heater to heat the car and have taken the eis out in the past when I was stranded without power so I took the eis and heated it with a blow drier and it worked – what would be the cost and procedure to fix it ?

  259. Simeon Koprivlenski 12 September 2014

    Hi ,

    I have a problem with my Merc C200 kompressor 2003 with the ignition switch. Mechanic told me it is not the key neither locking unit or control unit , but electronic ignition unit.
    I can not turn the key on unless i press and hold for a second on “opening ” button of key and than it turns and starts engine. As a results of EIS Failure most electrics in car don ‘t work such as wipers, radio , windows ect. They works if ignition is On, but once engine started they stop.

    Is electronic ignition switch repairable and how much would it cost?

    Thanks

    Simeon

  260. Jas 16 August 2014

    I have a 2003 CLK 320 – the battery died I put in a new battery but nothing happens when i turn the key – it wont crank
    I have 2 set of keys tried them both but same thing, the steering lock works as I turn
    the key to ON – I can hear the Fan go thats about it.
    nothing else happen

    is that a ECU issue? how can I confirm if yes how much to fix? and if its not will I still be charged?

  261. david 10 August 2014
