Neil C, London
Incredibly helpful when we were in a jam. Swift response time, very easy to work with. Would highly recommend!
Very quick and professional
The man turned up exactly on time, and he wasted no time getting on with the job. The van was fully equipped with everything to complete any job he was given. His phrase was “trust me “ and he only completed the job of getting my daughters car back on the road, when he was satisfied, it was ready to hand it back to me. Although a little expensive, I suspect it would have cost a lot more getting Mercedes to come out and do it. More than happy to use them again if unfortunately a situation like that were to happen again.
Brilliant service. Prompt and efficient. My engineer was very polite and I would recommend this service. Many thanks

Very prompt service. Young man was very polite and explained everything perfectly and also very thorough. Showed me how everything now worked properly. I also received phone call to say there may be a delay due to traffic (which wasn't a problem for me) but it was nice to be informed. All round, very satisfied and would recommend.
It was absolutely fantastic service. My only car key broke and I was stuck on a Sunday morning. Spoke to them on the phone and van man arrived almost at the said time and made a new car key for me. Very good service! Hope I don’t have to use them again but would highly recommend !!
Dan Tabony
Excellent service from the technician, who was friendly and knowledgeable, and was kept up to date with his arrival from Victoria who was very professional and a pleasure to talk to
Ms Zuccareli Delfine
Very flexible and professional. I used them before and was very satisfied that is why I called them again. My car had problem with the OBD reader and it took them longer than expected but they didn't charged me more. I will definitely use them again.

Excellent service. Although it wasn't an emergency I had a new spare key card within a day of contacting them. Helpful and friendly staff.

How Much Do You Know About Mercedes Car Keys?

  • Mercedes is one of very few manufacturers who used a very small variation of car keys over the years. From the early days of the immobiliser system being adopted, a plastic remote key that was used later has now been updated to a chrome finish one.
  • From early 2000 Mercedes car keys have integrated the immobiliser function. This way only a key programmed to a specific vehicle will enable engine starting.
  • Since the immobiliser introduction Mercedes has also integrated electronic ignition switches known as EIS and electronic steering column locks known as ESL on most of their models.
  • Many motorists will think of their closest dealership as their first port of call – even if this means paying for their car to be towed, sometimes twice, just for a replacement key. At a dealership, you will need a number of documents such as insurance, proof or purchase and more before the process begins, and once it does you are likely to have to wait for up to 10 working days.
  • Car Keys Solutions can supply Mercedes car keys on the spot ESL replacement mobile and EIS repair and programming. All of our services can be carried out mobile or at our base with minimum of inconvenience and fraction of cost compared with main agent.

Car Key Programming

If you have a Mercedes model that was manufactured after 1995, then it is highly likely that your Mercedes car keys will have a transponder chip. Sometimes, this can become desynchronized, and will need expert, diagnostic equipment to get it working again. We can carry out this service, right where you are.

Electronic Ignition Switch Repair

As any other electronic component Mercedes electronic ignition switches tend to fail over the time. Here at Car keys solutions we have a solution for those situations as well. Contact us with your vehicle requirement and we’ll be happy to assist you.

How Mercedes Car Keys Work?

If your car was manufactured after 1995, then you can be sure that your car key will have a transponder chip inside of it. This chip will be programmed to your individual vehicle, and connects to the immobiliser system (EIS) within your car to allow the car to be switched on. If the correct chip is present, your Mercedes Electronic Ignition Switch (EIS), will allow your vehicle to start. If however, the EIS detects that the wrong chip is in place, the engine will not start. This is impossible to bypass or override, and because of this the safety and security of your Mercedes car is improved. The chip is encrypted with a number of sophisticated coding systems, which only the latest diagnostic equipment is able to read.

When it comes to replacing a lost, stolen or broken Mercedes-Benz Car Key fob, there is a two stage process that you will have to go through. A new key blade will need to be cut accurately to unlock the doors and fit in the ignition. The second step is that the transponder chip is paired to the Mercedes-Benz vehicle.

Please note: If your Mercedes Remote Car Key is incorrectly programmed the vehicle will fail to start.
