IGNITION KEY DIFFICULT OR UNABLE TO BE TURNED OR REMOVED – KEY-IN-IGNITION WARNING CHIME SOUNDING WITH KEY REMOVED Some 2000-2005 Focus vehicles may exhibit ignition key related issues including difficulty or an inability to turn the key, an inability to remove the key, or (2005 only) the key-in-ignition warning chime continuing to sound even when the key is removed. ACTION Based on the vehicle’s symptom, refer to the appropriate Service Procedure. SERVICE PROCEDURE UNABLE TO REMOVE IGNITION KEY 1. Check if the inability to remove the key is the result of normal operation of the key removal inhibit circuit: In automatic transmission equipped vehicles, the key removal inhibit solenoid (within the ignition switch assembly) is energized when the gear selector is moved out of the park position, and prevents the ignition key from being removed. If the gear selector is in any position other than park when the key is rotated or turned off, the key removal inhibit circuit will not release the key (key cannot be removed). To remove the key, the gear selector must first be placed in the park position, then the ignition must be cycled to run and back to lock. This is normal, do not replace the ignition lock cylinder if it is operating as described. 2. Refer to Workshop Manual, Section 307-05 and follow diagnostics for the “shift interlock system”. The shift interlock system includes the key removal inhibit circuit, which may be causing the concern. If the shift interlock system is operating correctly, replace the ignition lock cylinder. Refer to Workshop Manual, Section 501-14, “Ignition Lock Cylinder Functional” removal and installation procedure. DIFFICULT OR UNABLE TO TURN IGNITION KEY

Power Door Locks Inoperative Diagnostic Instructions • Perform the Diagnostic System Check – Vehicle prior to using this diagnostic procedure. • Review Strategy Based Diagnosis for an overview of the diagnostic approach. • Diagnostic Procedure Instructions provides an overview of each diagnostic category. Diagnostic Fault Information Circuit Switch Side Supply Voltage Relay Door Lock/Unlock Signal Door Latch Control Driver Door Lock Switch Ground Passenger Front Door Lock Switch Ground BCM Ground 1. Door Lock Malfunction 2. Door Lock Switch Malfunction Circuit/System Description The DR LCK fuse supplies battery positive voltage to the body control module BCM for the door lock system. The BCM supplies and monitors a reference voltage to the door lock switch through the door lock switch lock/unlock signal circuit. The door lock switch also receives a constant ground source. If a door lock switch is placed in the lock position, the reference voltage is taken directly to ground and the BCM senses 0.0 volts on the signal circuit. If a door lock switch is placed in the unlock position, the reference voltage is taken to ground through a 1.5k ohm resistor that is internal to the door lock switches and senses approximately 2.9 volts on the signal circuit. This is how the BCM determines what portion of the door lock switch was activated. The BCM, upon receipt of a door lock switch lock or unlock signal, will switch the appropriate door lock actuator control circuits to battery positive voltage. The opposing side of the door lock actuators are connected to ground internally within the BCM through the other door lock actuator control circuit and the doors will lock or unlock appropriately. Vehicles without keyless entry have two internal drivers in the BCM to control the door lock actuators. All door lock and all door unlock. Vehicles equipped with keyless entry have three internal drivers in the BCM. Driver door unlock, passenger door unlock and all door lock. This is done to isolate the driver door lock actuator so it can be unlocked by itself using the keyless entry transmitter.
The following diagnostics might be helpful if the vehicle exhibits the conditlon(s) described above. Use the appropriate recommendation based on what symptom has occurred. Recommendation/Instructions No DTCs Review Corporate Bulletin Number 05-02-32-002B to assure you do not have a blown 60 amp steering fuse. The fuse can be blown during improper jump starting of the vehicle on the HHR and ION. Check for this particularly for tow in conditions. DO NOT replace the steering column unless an internal short has been Identified in the column that is causing fuse to blow. Power Steering Warning Message on DIC with DTCs C0176 and C0476 This condition is often the result of excessive lock-to-lock turns of the steering wheel, causing the thermal protection in the Power Steering Control Module (PSCM) to take the steering motor temporarily off line. This is a normal operating characteristic of the system. DO NOT replace the steering column for this condition. Refer to Corporate Bulletin Number 06-02-32-002B for additional information

The following procedure applies to vehicles that have functional lock cylinders, ignition keys available for the vehicle, or ignition key numbers that are known and the proper key can be made. REMOVAL 1. Disconnect battery ground cable, then remove steering wheel as described below. Ensure steering wheel is in full up position on models with tilt steering. a. Disconnect battery ground cable (two ground cables on diesel engines). b. From underside of steering wheel, remove screws attaching horn pad to steering wheel spokes. c. Lift up steering wheel pad, then disconnect horn wires and electrical connectors from pad. d. Remove steering wheel attaching bolt and damper, if equipped. e. Remove steering wheel using steering wheel remover T67L-3600-A or equivalent, Do not use a knock-off type wheel puller or strike end of steering shaft, as damage will result. On models with tilt steering, remove tilt lever, then the steering column collar by pressing on collar from top and bottom while removing. On all models, remove lower dash panel trim cover, then the column shroud retaining screws from bottom of column shroud. Remove bottom half of shroud by pulling shroud down and toward rear of vehicle. Move shift lever as required to ease shroud removal on models with automatic transmission. Lift top half of shroud from column. Turn lock cylinder with key to ON position. Selector lever must be placed in PARK position on vehicles with automatic transmission. Push down on lock cylinder retaining pin using a 1/8 inch diameter wire pin or small punch, then pull lock cylinder from column housing, Fig. 4.
