Installation & Replacement
Replacement normally requires basic tools: screwdrivers, Torx bits and pliers. Remove interior trim to access door lock units, disconnect linkages and electrical connectors where present, swap the old lock for the new unit and reassemble. Ignition cylinder replacement is similar: remove steering column trim to access the cylinder, replace and verify key operation and steering lock engagement. If you are unsure, consult a repair manual or a professional technician.
Common Failure Causes
Locks commonly fail due to mechanical wear of tumblers, key profile wear, corrosion from moisture ingress, impact damage or contamination. Ignition cylinders can stick or fail as a result of worn wafers or debris. Replacing the full set with matched keys often resolves related security and convenience issues.
