How can I fix faulty locks on a Hyundai i10?

My 2008 Hyundai i10 keeps unlocking and unlocking itself at night. The car's been to the garage and they have reconfigured the fob but still happens. Any ideas?

If the fob has been eliminated as the problem then moisture has got into the locking system, either the rear hatch lock servo or the ECU inside the driver's door.
