Look at my actuator repair thread. I show in there how to manually disengage the secondary lock. If the motor dies on the secondary you will not be able to open the door. If you can get the door panel off you could move the secondary lock manually and open the door.

Caveat: If the secondary lock motor works only in the lock direction, you'll lock yourself out again if you lock the door from outside.

PS: actuators die when the $6 motor inside fails. I've repaired four of them now between wife and my car for about $6 per door vs $230 per OEM actuator.
