REPLACING LOST PASS-KEY (R) III IGNITION KEYS/IGNITION CYLINDER /STEERING COLUMN ASSEMBLY/PCM
To replace lost PASS-Key� III ignition keys if all currently programmed keys are lost, it is necessary to determine the mechanical cut. Mechanical codes are recorded on the vehicle invoice. If these codes are available, use them to create a new key. If they are not, follow the procedure below.

The mechanical cut must be determined First. The mechanical cut can be determined from the key code on the ignition lock cylinder or from the original key "knock outs." If the mechanical cut cannot be determined, the ignition lock cylinder must be replaced.

To "learn" the new PASS-Key (R) III key use the following procedure:
1. Insert a valid mechanical cut key and rotate it to "RUN."
2. The "SECURITY" telltale will remain on solid for the length of the auto-learn timer (10 minutes).
3. When the auto-timer expires, the telltale will turn off.
4. Once the telltale turns off, remove the key.
5. Repeat Steps 1-5 two more times (total of 30 minutes).
6. Insert the newly learned key into ignition cylinder and turn to "RUN." The "SECURITY" telltale should remain off indicating the new key has been learned.
7. Any additional keys (up to a maximum of 10) can be learned using the "Learning PASS-Key (R) III Ignition Keys (Quick Learn)".
