Hi!
I'm new to this forum. I'll probably be here quite a lot now that my CD220 is around 8 years old and I'm not getting any richer lol.
I've got a strange problem with one of my smart keys and was wondering if someone here has experienced this issue, or who knows of it, and perhaps knows how to remedy it?
The car is a CD220i 2004 W203 facelift.
The one smart key works perfectly *every time*.. click the fob button, all the doors open, car starts, car stops, all doors lock.. lovely.
The other identical spare key happily opens the drivers door *every time*, but intermittently fails when unlocking the other doors, same goes for locking. The key also lets me start the car without any problems.
The lock/unlock button on the dash works perfectly.
Logic leads me to believe the issue is with the spare key itself. I initially thought it could be a limitation of the spare key but the fact that it randomly locks/unlocks the other 3 doors leaves me scratching my head
I promise I'm not being lazy just registering here and asking for help. I've been searching google for ages and just can't find a solution. I don't think it's batteries. I found some info about syncing keys (which may have not been relevant), tried the process several times but had no joy.
If anyone could help it would be appreciated. Many thanks
