Car failed to unlock...?

Programming went mental on the car the other day.

Wouldn't let me in after a double tap on the fob. Tried locking and unlocking - no response. Used key then it seemed to behave. Soon after (possibly at the same time - didn't notice right then) trip computer and clock reset. And the one-touch wind-up of the drivers window decided not to work briefly. Any known foibles with the security programming on these things? Or is it just my car gone doolally...?

Churs.
