I have a 2004 Mazda Protege 4-Door with power doors, and the locks will randomly unlock themselves from time to time while the car is parked. No keyless/remote entry, and the key is not in the ignition.

It's a problem because we can't ever leave the car unattended if there are valuables in it — we have to keep it within sight at all times to prevent theft.

Any ideas as to what's causing the locks to unlock like this?
