Mercedes-Benz's ignition switch (often referred to as immobilizer module) can become faulty, and in some cases due to user error. For example, some common reasons why the ignition module failed are:

  • Low battery voltage
  • Power surge due
  • Connecting jump-starting cables while key is in the ignition.

During any of the above scenarios, the EIS-EZS may lose its memory. While it can be diagnosed with Start Diagnostic Scanner used at dealerships, it can’t be repaired with this scanner. Mercedes' dealers don’t repairer a bad EIS-EZS module. They will recommend that the module be replaced. That’s not necessarily the only solution, see alternatives below.


We will repair your issue and mail out the ignition switch within 48-72 hours of receiving your
1) Ignition switch,
2) Existing keys for the ignition switch.

Easy and clean look

Very nice extension wires. Sheath is tough and the connections are tight. Very easy to install. I ended up to tuck in the wires instead of cutting because it was a little long for my application. Works great and had no issues. Pair the wires with my Nilight light pods. You can buy the wire but this was easier and cheaper than getting the wire and sheathing separately.
