Mercedes EIS Repair – EZS Immobiliser Key Module – ESL + KEY Repair Service
Sinspeed EIS Repair Services
Welcome 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
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.

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.

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
Hi Alan
Thanks for the enquiry,
I agree 2 EIS units to fail in the space of 5 years and the second being a brand new part from MB is definitely not good. We can test + repair the unit for you and I’ve sent you over an email quotation for the repairs. We do ask all customers to send the steering lock with the EIS module and key just so we can test it but if you’re 100% sure it is working correctly then you can leave it out and send only the Key + EIS Module.
Kind Regards

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

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?
Hello Craig
Thank you for your enquiry,
Being an accident damage vehicle it’s always hard to pin point what exactly is causing the non-start issues but from what you’ve described it can be a faulty EIS or ESL unit. I’ve sent you a quick email with full testing, repair and pricing information. We do serve customers in the USA all the time so that is not an issue.

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

Hi, Jason!
My w211 doesnt unlock sometimes by pressing the unlocking key. When driving sometimes all the warning lamps in the dashboard goes on and xenon lights restart. One guy diagnosed my car and and told me that eventually i will have to replace EIS. Is it really so? How much would this repair cost and how long should it take?
Hello Armands
Thanks for the enquiry,
If it is the EIS module causing this fault then it will require replacement or a repair. We can offer full testing and repair services at a much more affordable price than having it replaced and programmed. With our repair services you don’t need to worry about additional programming costs because the unit will stay coded to your vehicle.
I have sent you a quick email with full information on the repairs and pricing.
Kind Regards
