I've seen cases where the lock gets out of sync and I would try the escape hatch process.

Go in the car climb into driver spot.

Roll down driver window.

Put key Into the driver door lock lock it twice. The clown nose should blink fast to indicate the motion alarm is deactivated

Now try any door handle they should all dry fire and do nothing.

To exit a car that is double locked you have to hold the central lock button at the same time as pulling the door handle .

Try it a bunch of times. The motor may just be weak. When they fail they usually still work once in a while.

Once you get it out look at my repair guide. You can replace the brushes from a new motor in abiut an hour for about $12 for both main and secondary lock.
