Service Specifications

A common problem that Mercedes owners often experience is that the key no longer turns in the ignition. This problem is usually caused either by a lousy shifter module, a defective key, a failed Electronic Ignition Switch (EIS), or a bad steering lock module (ESL). 


This issue is usually familiar with the Mercedes-Benz E-Class, C-Class, S-Class, CLK-Class, SL-Class, and ML-Class models. 


Some of the common symptoms that indicate that your ignition module might be faulty are: 

  • Key doesn’t turn in the Mercedes Electronic Ignition Switch (EIS)
  • Key doesn’t turn in the Mercedes EIS when there’s cold weather
  • The key turns in the Mercedes EIS, but the ignition lights on the instrument cluster don’t switch on
  • Key sometimes doesn’t turn in the Mercedes EIS

On the instrument cluster message appears, please remove the key, and nothing else happens.


At VEPro, we would test the electronic ignition module (EIS-EZS), electronic steering lock (ESL), and keys of your Mercedes to detect the faults. We would then repair it and send the fully repaired and functional items back to you promptly.
