Over christmas every so often (usually on the cold nights) i unlock my car with the remote central locking and the door wont open, then the car locks itself again. After a few attempts im in and all good.
Tonight i did the same, car unlocks, the boot and 2 rear doors open fine, both front doors dont. The pins inside both come up and the car starts and drives (had to climb over to to get home).
Even just using the key in the lock doesnt work, the central locking operates, door pins rise but door still wont open. I came to my car at 11.30 tonight to find this i've used my car throughout the day and both doors have opened fine for us.
as i said it's done it temporarily before so im not sure if something mechanical has broken as it usually stops after a few attempts.
Any ideas?

gotta use my car in the morning for work and i dont feel comfortable driving 'trapped' inside.
