Where is the transponder on a GM passkey?
This system uses a special key (PK3 stamped on the shoulder of the key) with a transponder under the rubber cover. The receiver module is located next to the lock cylinder. When the key is positioned next to the lock cylinder receiver module, it energizes the transponder which sends a coded signal to the receiver.
How to reset the theft system in a Pontiac Grand Prix?
Enter the vehicle and insert the ignition key into the ignition. Turn the ignition to the “ON” position but do not start the engine. Wait 30 seconds and start the engine. Verify that none of the security lights on the dashboard are flashing or illuminated.
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 reset the PASSKey System on a Chevy?
Passkey II reset procedure, reset security system on chevy, buick, oldsmobile, cadillac, pontiac, saturn, hummer Make sure the battery if fully charged because this procedure may take up to 30 minutes and you cannot start the vehicle during this time. The BCM and PCM must be in working order and the Passkey system repaired
Enter the vehicle and insert the ignition key into the ignition. Turn the ignition to the “ON” position but do not start the engine. Wait 30 seconds and start the engine. Verify that none of the security lights on the dashboard are flashing or illuminated.
How to bypass vats, Passkey and PassLock security systems in GM?

Where is the theft deterrent module located in a passkey?
Passkey II – The Passkey II system has the Theft Deterrent Module (TDM) function stored in the Body Control Module (BCM). The TDM portion of the BCM will validate the resistive chip in the ignition key.
How does a PASSKey System work on a car?
The PASSkey-II signal is a similar square-wave pulsed-ground, but at a 50Hz rate, 50% duty cycle. The system uses two leaf contacts in the outer end of the ignition lock cylinder to connect to the resistor pellet embedded into the key blank just below the bow.
Where are the resistor pellets on a GM Passkey?
GM used two strategies to determine if someone was trying to steal the vehicle. The early systems used the first generation PassKey system. Then GM changed to the PassLock system. See the resistor pellet on the shaft of the key to the left of the plastic. The first generation PassKey systems incorporated a resistor pellet into the head of the key.
