Mercedes EIS / EZS Immobiliser Key Module Problems

 

Symptoms we can diagnose and repair are:

• Unable To Turn The Key
• Unable To Start The Car
• Turn The Key – But Car Won’t Start
• Intermittent Ignition Key Faults
• Vehicle not responding to remote

If the EIS unit becomes faulty, the key will not turn & start the engine, this function will be de-activated and the module will be locked for security purposes. This will stop the engine from starting. It is very unfortunate but also a very common problem as there are many reasons as to why these units fail. 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 or corruption of the EIS module and it cannot be repaired or re-flashed using the usual Mercedes diagnostic systems. At this point most people will advise you to purchase a new ignition unit which can work out extremely expensive.
One of the main problems is the CPU chip inside fails or for example crashes just like a computer or PC.

OUR SOLUTION:

We can remanufacture your existing EIS and ESL Module unit and save you a lot of money. We thoroughly test & repair all EIS modules . When the unit is returned to you, you will not be required to reprogram or re-calibrate the unit – simply plug & play.

After we have repaired your EIS module, you will be able to insert the key, turn the key and start the vehicle with no troubles at all. We do recommend that you check the battery supply voltage prior to installation to ensure there are no faults on the vehicle which could potentially cause failure of the replacement / repaired unit. If you lost all keys from your car, we can programming new keys.
