I locked my car as normal last night and have just gone to open with the remote - won't work neither will my spare remote. Anyone any ideas?

Sounds like you've got a problem with the radio element of the system. The W203 can also unlock using IR (which sounds like what is happening here). Think there's an aerial or amp that the radio element of the unlock utilises.
I was an early adopter of the new style Chrome key but sourced mine from the US (who use a different radio frequency). My chrome key only works in a way similar to the way you describe, i.e. using IR but not Radio. Can you try moving a little further away from the car (but remain in sight of the drivers the door handle) and try lock / unlock to help prove my theory. E.g. my Chrome key won't unlock from the passenger side or the front of the vehicle, so I still use my original keys almost all the time!
Drive the car and try it somewhere else - it *might* just be radio interference.
However prob more likely to be a car problem (unlikely to be key if both do the same).
Hi,
I think if it was my C43 I would try disconnecting/reconnecting the battery, In my understanding effectively rebooting the electronics of the car, worth a try and costs nothing.
Thanks. But not really happy to try that might make matters worse. Wont i loose all my star codes etc?
Think it's quite likely to be the aerial / antenna that receives the radio signal from the car or some interference at the location you were at. I doubt that the scanner or anything else has caused the problem with your key.
I think a member on here had a similar problem a while back, although I think his was caused by some modding after replacing the rear SAM. Like I say I believe there are two ways of operation for the key IR & Radio. My theory is that yours is only working on IR at the moment.
To confirm my theory have you tried unlocking from the other side or the front of the vehicle?
That doesn't smell right to me. I know this may sound daft, but upen all the windows then try locking / unlocking with the key fob. If it works OK then maybe the dealer's right. If not, then I smell BS...MB reckon because i have had the windows tinted it has interfered with the radio signal
I was going to suggest something similar and have maybe the doors open.That doesn't smell right to me. I know this may sound daft, but upen all the windows then try locking / unlocking with the key fob. If it works OK then maybe the dealer's right. If not, then I smell BS...
