I have a 2003 CLK 55 AMG, everything was working fine until I parked it up for 2 weeks, now it won't unlock with the remote (or the spare remote) The manual key will not unlock the doors either, I can get into the boot and I have checked all the fuses in there that I can find and they seem OK.


I guess it could be that the battery has gone flat even though I had a new one a few months ago. The battery is under the bonnet, so I can't get to that as I cant get into the car !!


Can I open the bonnet manually at all so I can get to the battery?


Any other ideas as to what might be wrong?


Many thanks

It is the convertible version just for completeness.

Do you have folding rear seats? Just a thought.

adwclk55

Unfortunately the seats don't fold down. Thank you for the reply though

Yes, no folding seats on the cabriolet due to the roll bars. So, does the mechanical key not turn the door lock or does it turn and then not unlock?

The key will turn in the door lock about 1/4 turn anti clockwise, and about 1/8th turn clockwise, but does not operate the door lock ?!?


The same key will operate the boot lock manually ?!?


I have been away (with a different car) hense the delay in replying, any help would be much appreciated as currently I have a purely decorative CLK !!


Many thanks

It sounds like you have a mechanical problem in the door that is not allowing the lock to actuate. You may just have to have it towed to a shop so that they can open the hood and charge/replace the battery. The other alternative is to break a glass to get in. If so, I'd break the passenger door glass. The glass in the doors is easier to replace than the rear side windows.

I recall the mechanical key has to turn 1/4 turn either direction to lock and unlock.

Try WD40. This key cylinder is not used often so maybe it's rusted.
