Hello,

I have a very strange issue with a recently purchased 300E. The locking mechanism on the driver's side door didn't work to start with, but today after installing a new door panel on the driver's side the locks went haywire! Before, I could lock the car using the trunk lock and the passenger side door with no problems. But now about five seconds after locking the car, the car unlocks itself! I have tried locking and unlocking the doors about a hundred times but nothing works. PLEASE HELP!

Thanks,

Roy
