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.

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.
