Rear Hatch Lock Problem

[larrylava]

Today for some reason my rear hatch lock is mysteriesly unlocking all by itself. When it did it the first time, i just shut the hatch again and it was fine. I got home and i was sitting in the garage and it just unlatched and you can hear it keep unlatching till i shut it again. I've checked the key and it seems fine. The only way i can keep it locked is to turn the alarm on.
I have a 01' 3.0 X5.
Has this happened to anyone?
How did you fix it?
