w204 two key fobs work differently.

[TomKoval]

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

In the same time, one by one?
There is led light in the key?
Where?

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.

At the same time, there is an led which is only seen when it lights up.
