If it is unlocking, but not locking, I'll bet the actuator is slipping on the rod that unlocks the door. Pop off your panel and look at the connetion between the actuator and the stock rod.. There should be a little screw that you can tighten to hold the two together more firmly. This happened on my old RX7 (miss it now). Good luck.
