I have spent hours trying to get the retainer clip inserted to hold a new door lock cylinder. Anyone know the secret? My next step is to remove the little washer that would go up against the door to keep water out - put in some silicon sealant and it may give me some additional room to get the clip in. The other alternative is to drill a 1.5" hole into the inside door frame to easier access to the clip. I even took the door off the car hoping it would make it easier. Suggestions? Once I replace the driver's door - then I will tackle the passenger door, so I have matching locks. Then try to find new door latches - the driver's door definitely needs replacing - but that is the one I cannot find.
