Central locking playing up

[RodOGW]

Had to leave my car for a couple of days in a secure building so incase it had to be moved I only locked it with the key so that the alarm (after market Gemini) didn't go off inadvertantly when it needed moving. When I returned to it this morning I could not unlock the drivers door either with the key or the remote - and still can't - passenger door and boot can only be unlocked with key. Pressing the remote sets the alarm and still closes the windows but will not open doors. Tried the equivalent of cotrol/alt/delete and disconnected battery - just to see if anything needed to reset itself - but nothing - still having to crawl in over passenger seat.

Any suggestions?

Managed to get driver's door, boot and petrol cap working. Squirted large amount of WD40 into the driver's door lock and magically the key turned and now the remote works. This was really a last ditch/give-up action and don't know why I did it - pictured weekend of trying to get door panel off locked door - taking seat out, wiring, etc. etc. But it worked.
Still can't get passenger door to work off remote but it works fine with key.
