Lock Cylinder, Front Passenger Side

A person should disconnect the battery before proceeding with ignition lock cylinder service and repair tasks. Begin the procedure by first taking off the tiller handle and shank before moving onto the three screws securing the bottom steering column shroud. The shift selector boot needs to be moved aside if it is present. Put the ignition key into the slot and set the key to ACC position. Rotate the PATS transceiver after unfastening its passive anti-theft (PATS) transceiver tabs to reveal the pin hole for ignition lock cylinder release. Insert the appropriate tool to press down the ignition switch lock cylinder release pin while you withdraw the ignition switch lock cylinder out. Verification of ignition switch lock cylinder operation should be performed after reversing the removal steps.

Your service of a non-functional ignition switch lock cylinder needs to start by removing the battery power source. The initial step is to take out the steering wheel before removing the tilt wheel handle and shank. The first step requires removing three screws that fix the lower steering column shroud while optionally placing the shift selector boot to the side. First, twist off the ignition lock cylinder cap followed by tab release to slide off the passive anti-theft system (PATS) transceiver from the steering column. Remove the PATS transceiver by disconnecting the electrical connector and then remove it from position. Drilling the lock cylinder retaining pin requires an 1/8-inch diameter drill bit while drilling down the ignition lock cylinder key slot needs a 3/8-inch diameter drill until it becomes loose. Following steering column debris removal discard the ignition lock cylinder and all drill waste and perform a complete cleaning of the area before checking for steering column damage. The installation process finishes after executing the reverse steps of uninstallation.

A repair or servicing procedure for the door lock cylinder requires the removal of the exterior front door handle first. You must separate the door lock cylinder actuating rod and take out its clip and the door lock cylinder. Each repair of lock cylinders involves discarding problematic devices followed by creating new components through proper lock repair packages containing precise construction guidelines for building replacement parts that correspond to existing vehicle key systems. To install the lock system follow all the removal steps in reverse order.

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.

The procedure for repairing the door lock cylinder starts with taking off the exterior front door handle. You need to disconnect the door lock cylinder actuating rod before taking out the clip and the door lock cylinder. A new lock cylinder is built for individual units through the use of appropriate lock repair packages containing both installation instructions and the necessary components to match current key codes. The installation process should follow the reverse steps of removal.

First, disconnect the battery ground cable.

Remove the bearing retainer, the steering column lock housing bearing, and the steering column lock gear.

Next, disconnect the door lock cylinder rod and remove the clip.

Next, disconnect the door lock cylinder rod and remove the clip.

Twist off the cap from the ignition switch lock cylinder.

Reactivate the Supplemental Restraint System (SRS), taking care to read and follow all warnings, notes, and instructions related to the SRS reactivation procedure to avoid the risk of serious personal injury.

Disconnect the door lock cylinder actuating rod and, if applicable, disconnect the door disarm switch electrical connector.

Begin by removing the exterior front door handle.

Next, disconnect the door lock cylinder actuating rod and, if applicable, disconnect the door disarm switch electrical connector.

Ignition Lock Grease FOAZ-19584-A or an equivalent that meets Ford specification ESA-M1C232-A.

Deplete the backup power supply by disconnecting the battery ground cable and waiting at least one minute, and disconnect any auxiliary batteries and power supplies if equipped.

Position the shift selector boot aside.

The lock repair package includes a detailed instruction sheet for building the new lock cylinder to match the vehicle's current key code.

Firmly install it to engage the four retention tabs into the lock housing.

Use a 3/8-inch diameter drill to drill down the middle of the ignition lock key slot until the ignition switch lock cylinder breaks loose.
