A170 Doors not unlocking.

[Eagle17]

My 2004 A170 (W268) will unlock the driver's door with the key button, but will not unlock the other doors or the boot. It will lock all doors. Any idea what is causing this?

I think the key can be programed to open all doors and boot, or just the drivers door, handy if you are the only user. Sorry I can't help further but I am sure someone will be along to help shortly.
