Is there anyway of resetting the central locking on the A class?

When I unlocked the car in the past it unlocked all the doors and the boot.
Now for some reason from last week it will now only unlock the drivers side.

Also since this problem started when I unlock the car using the central locking button on the dashboard, the car won't automatically lock itself when its reached over 10mph like it used to.

Can this be reset some how using the remote or is it a computer problem and needs resetting at a garage?

Cheers!

 

yes you can change the global and indivual locking.

i forgot and i need to check from my office on monday. remind me.

how many buttons on your key? (only 1?).

 

Excellent, its a two button remote.

Under the back seat is where the central locking system is located. It is wrapped in foam. remove foam and find where electrical connections are made. Pull apart and let it sit over night.
Replug next day and hopefully it will reset memory. I just did it on my 300e and I am sooooo happy. Everything works again. Good luck
