How to Service and Repair an Ignition Lock Cylinder on Mercury Grand Marquis?

Disconnection of the battery power is the first step needed to repair or service an ignition switch lock cylinder. First remove the shank together with the tilt wheel handle and then unscrew the three screws which secure the lower steering column shroud. Move the shift selector boot to an appropriate position during the service. You should insert the ignition key into the slot and position it at ACC. First press the patency anti-theft system (PATS) transceiver tabs toward the outside before rotating the transceiver to reach the ignition lock cylinder release pin hole. The ignition lock cylinder should be pulled out while using a suitable tool to press the release pin. After reverse-installing the lock cylinder system users should test its operational functionality.
