How to Locate Your Vehicle Identification Number (VIN)
Finding your vehicle’s VIN is essential for ensuring your module is programmed correctly. Follow these simple steps to locate it:
Dashboard
- Sit in the driver’s seat and look on the lower left-hand side of the dashboard, just above the steering wheel.
Alternatively, you can stand outside the vehicle and look through the windshield; the VIN may be more visible from this angle.
Driver-Side Door
- Open the driver-side door and examine the area where the door latches. The VIN is often located near the seatbelt return mechanism.
- Check inside the doorjamb, particularly where the mirror is mounted when the door is closed.
Other Locations
- Trunk Lid: Some vehicles have the VIN listed on the trunk lid or under the spare tire.
- Under the Hood: In some cars, the VIN can be found on a label attached to the engine bay.
Key Details:
- The VIN should be a 17-character alphanumeric sequence.
- An example of a typical VIN might look like: 1HGBM22JXMN109186
Check the driver-side door. The VIN should also appear on the Federal Safety Certification Label which is in all new cars. This label should appear on the driver’s side door in the following places:
- On the driver-side doorpost. With the door open, check the spot where the door latches. It should be near the seatbelt return.
- Inside the driver-side doorjamb. Open the door and look straight ahead. The VIN should be inside the doorjamb, where the mirror is located when the door is shut.

Passkey III – transponder ignition key
The Passkey III anti-theft system uses a transponder inside the head of the ignition key. The
exciter inside the ignition lock cylinder energizes this transponder when the ignition switch is
turned on. The transponder transmits a unique signature to the theft deterrent control module.
If the key signature transmitted is acceptable to the theft deterrent control module, the theft
deterrent control module will transmit fuel enable password to the PCM. If the fuel enable
password is correct, the PCM will start the vehicle.
To perform a relearn on a Passkey III system, make sure there is a fully charged battery in the
vehicle. The battery will be used for 30 minutes without the alternator available for charging.
Connect a battery charger to the battery to ensure power is available while programming.
When performing this relearn, all previously learned keys will be erased. Additional keys may
be relearned immediately after the first key has been learned by inserting the additional key
and turning the ignition switch to on within 10 seconds of removing the previously learned key.
1. Insert a master key (black head) into the ignition switch.
2. Turn key to the “ON” position without starting the engine. Security light should turn on and
stay on.
3. Wait for 10 minutes or until the security light turns off.
4. Turn key to the “OFF” position for 5 seconds.
5. Turn key to the “ON” position without starting the engine. Security light should turn on and
stay on.
6. Wait for 10 minutes or until the security light turns off.
7. Turn key to the “OFF” position for 5 seconds.
8. Turn key to the “ON” position without starting the engine. Security light should turn on and
stay on.
9. Wait for 10 minutes or until the security light turns off.
10. Turn key to the “OFF” position. The key transponder information will be learned on the next
start cycle.
11. Start the vehicle. If the vehicle starts and runs normally, the relearn is complete. If additional
keys need to be relearned:
12. Turn the key to the “OFF” position.
13. Insert the next key to be learned. Turn the key to the “ON” position within 10 seconds of
removing the previously used key.
14. Wait for security light to turn off. It should happen fairly quickly. You may not notice the
lamp, as the transponder value will be learned immediately
15. Repeat steps 12 through 14 for any additional keys.
