Transmitter (key) operation seems o.k. If the problem is occuring at all receivers, drivers door, pass door and boot then seems the system requires synchronising.
To synchronise system, point transmitter at a receiver and press transmitter button briefly. Within 30 seconds lock and unlock the vehicle with the car key by the door or boot lock.
P.S there are 2-off fuses for the door module located in the boot aux fuse box. Check them both if problem still persists.
