It is nearly true, and the car will start, but will never get rid of the error codes from another car components eg: Listening the local mechanic there is only solution to buy whole starting second hand set online. In this case people trying cut the cost and looking for the alternative. In order to get new ignition barrel from main dealer there is the cost nearly 1K. The person who stolen the barrel he is planning to make the key and come to your car again shortly - making a key for sprinter is easy when ignition barrel is out. Usually, he discovers that first thing in the morning before set off to work. Recently there are many cases that the Mercedes Sprinter lost ignition barrel ( EIS or EZS) and owner can’t drive with car anymore.

– Then and only then, when all three control units agree it is the correct authorised key being used, will it allow the “Turn & Start” function to be activated. The ESL system will then look to see if the Engine ECU (Electronic Control Unit) agrees that this is the authorised key being used.

Each time the key is inserted, the EIS system will check the key and then ask the ESL (Electronic Steering Lock) system for verification that it accepts the correct key is being used. The vehicle will instantaneously carry out a sequence of test handshakes to ensure the correct key has been inserted.

The key has a sequential code to ensure the vehicle is not stolen. It is more like a plastic lego-brick with what looks like an infra-red panel at the face of it which is inserted into the EIS socket on the dash. The hardware being the switch is like a small socket in the dash to insert your key into – only, it is not a traditional looking key. Mercedes EIS/EZS electronic system is like vehicle heart (Electronic Ignition Switch) but sometimes fails making big trouble for us. Some of the most common reasons are listed below: It is very unfortunate but also a very common problem as there are many reasons as to why these units are failing – most are due to human error. This will stop the vehicle from starting.

If the EIS unit becomes faulty, the Turn & Start function will be de-activated and the module will be locked for security purposes. One of the main problems is the Motorola CPU chip which fails, even the newer batch of EIS modules have the same processor fitted so fitting a new module won’t solve the problem entirely, it’s how you look after the vehicle which plays a big part. At this point, you would have been advised to purchase a new unit which can work out extremely expensive when working out the total bill with programming and labour inclusive with VAT. 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.
