Just picked up a CLS55 the other night, and the keyless go was working fine. Then this morning, for some reason, it will still start/stop engine but won't lock doors when I push the button on the door handle, or unlock when I grasp the handle. Does this on both driver and passenger's side door. I changed a bunch of settings last night, thought maybe that was what did it... I reset settings to factory, but the problem hasn't gone away.

Any ideas? I read a few other threads that sounded like the same problem, but no solution was found...

Take it to the dealer. I had the same problem, they replaced the key fob's and a door switch.

Good idea, I just remembered the car's still under manufacturer's warranty (so used to buying used cars and having no warranty...)! I tested a little further, it seems that some door switches work some times, depending on location, but the driver's one almost never works. I replaced the batteries in the key, but now it doesn't work at all (!), so off to the dealer it goes tomorrow

I just can't get over how awesome this car is, to even care about taking it back to the dealer on the first day

it's a common problem. they replaced my drivers door handle.

make sure the other key is not still in the car if so it will not let you lock the doors

Car only came with one key unfortunately, so that's not the problem.

Will post pics soon, hopefully tomorrow!

what? get another key plus the valet/service key from the dealer and have the code changed. to think that another key is floating around is a bit scary.

Yeah, I think the first owner of the car lost the key. It's ok, I'm moving to another state soon, so I doubt whoever has that key will be able to find me Didn't know there's a service key, I'll ask the dealer about it when I take it to them tomorrow...

I hatethe keys, its likely justthe transmitter or battery, go directly to a dealer have em check. You can change the battery butIMHO it is a pain. I broke my key tryingto open it LOL.

Actually, while we're on the subject of KG, I don't suppose anybody has successfully disabled the annoying "Don't forget your key" beep when opening the door? It sounds like maybe either the instrument cluster can be flashed to newer version, or somebody with stardiagnose can fix it (where can I find somebody with stardiagnose in seattle area?).

I also have one single, loud annoying beep which occurs about 15-20 seconds after the car's power is enabled, but I haven't noticed anybody else complaining about such a thing, so I'm wondering if maybe its caused by the third party bluetooth in the car...
