Drivers door not unlocking on fob

[TurnerPhil]

G'day folks
The driver's side door won't unlock from the fob but the passenger door does as normal. When I unlock with the key the alarm goes off, blip the key and that stops. when I start it I get Alarm activated by drivers door. It will lock on the fob.
Has anybody had the same problem?
TIA
Phil

Yes, it will.
Contrary to what i said earlier I do have to lock it with the key and then get three horn beeps.
