• Q: How to replace the door lock cylinder with RPO Code UA2 on 2003 Cadillac CTS?

  A: The first step to replace the Door Lock Cylinder with rpo code ua2 requires the full up position for the window and the removal of the door trim panel. Access the outside Door Handle by pulling the rear section of water deflector away from the door opening before handling the Door Handle for removal. First remove the e-clip from the lock cylinder then remove the lock rod with its arm. Use a suitable prying tool to insert between reinforcement and roll pin before prying it down to grab the opposite end using pliers for removal. A drift punch can be used to eliminate the surplus roll pin. The next step involves removing the lock cylinder through the doorway at the back of the Door Handle. When integrating a new lock cylinder it is crucial to perform key and lock cylinder coding properly. The procedure requires plugging the lock cylinder into the handle cavity, setting roll pins in place and applying the e-clip to connect cylinder arm with rod. The finishing steps require installation of the outside Door Handle together with the water deflector and door trim panel.
