PASS-Key III - Programming
WHEN REPLACING THE PASS-Key III MODULEThe replacement PASS-Key III (VTD) modules are manufactured to be able to learn the FIRST key that is used to start the vehicle. When learning the first key, simply insert the ignition key and turn the ignition ON.
Learn More Keys Mode
The PASS-Key III module can learn up to 10 valid key codes to operate the vehicle. To program more keys, use the following procedure.
This procedure must begin with a valid key.
1. Insert a valid key into the ignition and turn the ignition ON.
2. Observe the PASS KEY telltale in the IP. After the 2 second bulb test, turn the ignition OFF and remove the valid key.
3. Within 10 seconds insert the invalid key to be learned into the ignition, and turn the ignition ON. The PASS KEY telltale will be illuminated while the VTD module is learning the key.
4. When the PASS KEY telltale turns OFF, more keys can be learned by repeating steps 2 and 3.
To exit the Learn More Keys Mode, turn the ignition OFF for more than 10 seconds.
Valid Key Code Counter
The VTD module has a valid key code counter that stores the number of valid keys that the module has learned. A maximum of 10 key codes can be learned by the VTD module. The value of the counter can be viewed using the scan tool.
ALL Keys Lost
If the valid key code counter is equal to 10, and if the customer has lost all the keys that the VTD module has learned, the PASS-Key III module can be reprogrammed to learn 10 new keys. This procedure will take 30 minutes to complete.
1. Cut the new key with the mechanical key code for the vehicle.
2. Insert the new key in the ignition and turn the ignition ON.
3. The PASS KEY telltale will flash at 1 Hz.
4. Leave the key ON in this state for 10 minutes.
5. After 10 minutes, turn the key OFF and then back ON within 10 seconds.
6. Repeat steps 4 and 5, for a total of 3 ignition key cycles.
7. After the third ignition key cycle 10 minute time period has elapsed the PASS KEY telltale stops flashing and the new key has been learned.
This procedure will reset the valid key code counter to 1. To program more keys, refer to Learn More Keys Mode.
ALL Keys Lost (Techline T50/T60 is Available)
If the valid key code counter is equal to 10, and if the customer has lost all the keys that the VTD module has learned, the PASS-Key III module can be reprogrammed to learn 10 new keys. This procedure will take 10 minutes to complete. The Techline terminal is used to input a security code into the VTD module to reduce the time necessary to learn keys in this situation. The Techline terminal can also load the security code into the scan tool for subsequent downloading to the VTD module.
1. Cut the new key with the mechanical key code for the vehicle.
2. Prepare the Techline terminal (and scan tool if needed) and connect to the vehicle.
3. Insert the new key in the ignition and turn the ignition ON.
4. Download the security code from the T50/T60/scantool.
5. The PASS KEY telltale will flash at 1 Hz.
6. Leave the key ON in this state for 10 minutes.
7. Turn the Ignition key OFF.
8. Turn the Ignition key On. The PASS KEY telltale will illuminate for 2 seconds and the new key is learned.
9. Disconnect the T50/T601scan tool. This procedure will reset the valid key code counter to 1. To program more keys, refer to Learn More Keys Mode.
