How to replace the rear Trunk Lock Cylinder on Cadillac Eldorado?

Begin the replacement by taking the rear compartment lid trim off first. Detach the lock cylinder emblem before moving forward. Use a flat-blade tool to pry off the retainer while holding a wooden wedge between the tool and lid body to prevent damaging the paint surface. Pull out the electrical connector and take off the cylinder unit from the trunk space. Place the gasket on the lock cylinder before putting the cylinder into the rear compartment lid . Retainer clip should be securely fastened as you reconnect the electrical connector and feed the lock release cable into the cylinder base. Reassemble the rear compartment lid trim and its badge after completing all installation steps.
