2007 S550 Rear door opens when locked

With just pulling the handle from the outside, the doors unlock. Front doors do not, but rear doors do. Any clue?

Yea, they aren't being locked--have the central locking system diagnosed, but not by you!

I'm assuming you have Keyless Go. Often, the sensors go bad over time and stop working. You should get it to somebody who has STAR so they can diagnose the issue. It may need replacement of the front door handles. It could also be something as simple as a fuse, so you may want to check them first.
