Mercedes EIS Ignition Switch Repair (All models)
Do you have a Mercedes key that no longer starts or has suddenly stopped working in the ignition? Does it not turn on the ignition anymore?
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).
Common faults
Key turns but won’t crank or start
No dash lights when key is inserted or turned
Problems can begin intermittently, and can be temperature related until complete failure
