CLK 320 W208 Key won't turn in ignition

[Glyn1981]

Hi all,

Apologies for this being my first post but I am trying to help my mother fix a problem on her CLK 320.

The key will no longer turn in the ignition and so won't start the car - I have searched and read a few threads about this but just want to check I have tried all I can before calling a Merc specialist.

I have located the spare key and this will not turn in the ignition either.

Both sets of keys can remotely unlock the doors, boot and open/close the windows. However when placed in the ignition they simply won't turn.

I don't hear the usual sound associated when placing the key in the ignition so I am assuming the car is just not recognising the keys for some reason?

Things I have tried so far:

Tryed the keys numerous times, locking/unlocking and trying again etc.

Disconnecting and re-connecting the battery

Using a screw driver to allow me to move the gear selector from park down to drive and back to park incase it was a gear selector sensor.

The car was used daily so I am assuming the battery is fine.

Any advice would be welcome!

Many thanks,

Glyn

Hi,
It sounds like the EIS switch is U/S (Ignition switch), my next port of call would be to call a good Indy, and get a STAR test done to confirm.
