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

Each ignition key (2) used in the Sentry Key Remote Entry System (SKREES) has a transponder chip included on the circuit board (4) beneath the cover (1) of the integral Remote Keyless Entry (RKE) transmitter (3). In addition to having to be cut to match the mechanical coding of the ignition lock cylinder and programmed for operation of the RKE system, each new Sentry Key has a unique transponder identification code that is permanently programmed into it by the manufacturer, and which must be programmed into the Sentry Key REmote Entry Module (SKREEM) to be recognized by the SKREES as a valid key. The Sentry Key transponder cannot be adjusted or repaired. If faulty or damaged, the entire key and RKE transmitter unit must be replaced. When the ignition switch is turned to the On position, the Sentry Key REmote Entry Module (SKREEM) communicates through its antenna with the Sentry Key transponder using a Radio Frequency (RF) signal. The SKREEM then listens for a RF response from the transponder through the same antenna. The Sentry Key transponder chip is within the range of the SKREEM transceiver antenna ring when it is inserted into the ignition lock cylinder. The SKREEM determines whether a valid key is present in the ignition lock cylinder based upon the response from the transponder. If a valid key is detected, that fact is communicated by the SKREEM to the Powertrain Control Module (PCM) over the Controller Area Network (CAN) data bus, and the PCM allows the engine to continue running. If the PCM receives an invalid key message, or receives no message from the SKREEM over the CAN data bus, the engine will be disabled after about two seconds of operation. The ElectroMechanical Instrument Cluster (EMIC) will also respond to the invalid key message on the CAN data bus by flashing the security indicator on and off.

Introduction Immobilizer Reset is a new feature that allows the registration of a new Master Key even if all original Master Keys are lost. Once the Immobilizer system is reset, all previously registered keys will be erased.Function
The Immobilizer Reset function is a 5-step process: Description 1. Using the Diagnostic Tester, retrieve a “Seed Number” through the OBD/MOBD Immobilizer function. S A “Seed Number” is a unique number provided by the Diagnostic Tester and validated by TIS in order to return a Passcode. 2. Using TIS, select Immobilizer Reset, and complete the request form to retrieve a “Passcode Number.”
S A “Passcode Number” is a unique number required by the Diagnostic Tester to reset the ECU allowing it to accept a new Master Key. 3. Enter the “Passcode Number” received from TIS into the Diagnostic Tester. 4. Confirm successful Immobilizer reset and new Master Key registration. 5. Register any additional customer keys.
