the lock actuator is probably shorted. they are riveted.
you'll need to remove the panel. check behind the red reflector, one phillips screw. you'll have to ck. closely for the others. if the panel doesn't come off easily keep looking. use a punch for the rivet; knock out the center,then gently pry in the center. left then right then up and down. you'll need a new rivet and a big rivet gun. good luck.
