Hi all.

I'm new owner of w204 2008. Car bought with two keys and all works fine but.
If I my daughter close car with her key (1) then when I open car with my key (2) all doors open except drivers.
I need to press open again or close and re-open to open drivers doors.
We tested and opposite; closing car with key 2 and opening with key 1 does the same thing, drivers door aren't unlocked.

Is this default behaviour?
Is there a way to change it?

Both fobs have new batteries.

Regards
Tom
 
From memory you can program the fob to either unlock all doors or unlock only the driver's door (anti carjacking). But it's odd that it unlocks all doors apart from the driver's door.
 
With a bit delay but I've replaced batteries just in case and press both buttons at the same time.
For now issue resolved.

Thanks

Tom
