Hope you get to this through the spam. Try this, costs nothing and is worth a go.

Open the drivers window and the bonnet, close the doors have all accessories off

Disconnect the battery for three minutes, reconnect the battery and turn on the side lights through the window (dont open the door) wait for 15 seconds then put the key in the lock and turn to the on position, dont start the car. Press and hold the lock button on the key for 10 seconds.

Remove the key and try all the doors for locking/ unlocking. start the car. If all works the problem is cured, if new problems occur repeat the process (This reboots the ECU and sincronises the keys to the locks)

I think the sidelight may be a bulb!
