I just bought a pre-owned 2007 CLS550. It has the keyless go system and the feature that unlocks the door with the key in my pocket works on every door except the driver door (!). Has anyone else experienced this ? The auto locking feature works on all doors, so the sensor seems to pick up the key on this door... Any input is appreciated...

 

usually needs a new door handle/ grab handle common problem with all keyless go.

 

It happened to me and I simply just replaced the batteries in my key fob and it started working again.
