Is there a relearn procedure for Passkey III?
Is there a relearn procedure for Passkey III?
In later versions called PassKey III, the key includes a transponder in the key. A relearn procedure IS required if the PCM is replaced. See this article for the relearn procedure on PassKey II systems. PassLock In later versions GM decided to take the key out of the picture. Instead, they mounted a sensor inside the lock cylinder case.
How to make a link GM passkey no start bypass?
HERE IS THE LINK GM Passkey NO start Bypass Cut two terminals off the end of the terminal strip. Set the rest of the terminal strip aside. Takle one of the 2200 ohm resistors and bend the leads as I’m doing here. Then cut off the excess lead wire. (The color code for the resistor is three red bands.)
How does a PassLock work on a GMC Sierra?
PassLock In later versions GM decided to take the key out of the picture. Instead, they mounted a sensor inside the lock cylinder case. As the lock cylinder rotates, a magnet mounted on the cylinder passes the sensor mounted in the lock cylinder case, activating the sensor, which sends a coded signal to the body control module (BCM).
Where is the transponder on a GM passkey?
GM revisits the key system, only this time they located an antenna/transponder in the head of the key. An exciter located at the opening of the lock cylinder activates as the key is inserted. The exciter sends a radio signal that’s received by the transponder.

How does a GM passkey and PassLock work?
If you see 2.5 volts and the vehicle still won’t stay running, check the fuel pump relay. Here’s how it works, The lock cylinder reads the resistance of the pellet in the key and transmits that data to the theft module. Meanwhile, the PCM provides 5 volts on the dark blue wire.

How to turn off GM PassLock security Telltale?
Here it is in it’s entirity. Turn ON the ignition, with the engine OFF. Attempt to start the engine, then release the key to ON (vehicle will not start). Observe the SECURITY telltale, after approximately 10 minutes the telltale will turn OFF. Turn OFF the ignition, and wait 5 seconds .
