What year? A lot of them can be bypassed by resistor.

Google VATS bypass or Passkey bypass. Tons of information on the web.

That immo system is in the lock, not the key.

Find the Passlock harness under the column, it has three wires, yellow, org/black and red/wht. Cut the yellow wire (leave the rest connected) and on the truck side solder a 2200 Ohm resistor to the black wire.

This video will show you where the wires are, but ignore his method.

Then you just do a Passlock relearn:

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.
Repeat steps 1 through 4 two more times for a total of 3 cycles/30 minutes, the vehicle is now ready to relearn the PasslockTM Sensor Data Code and/or passwords on the next transition from OFF to CRANK.
Important: The vehicle learns the PasslockTM Sensor Data Code and/or password on the next ignition switch transition from OFF to CRANK. You must turn the ignition OFF before attempting to start the vehicle.
Start the engine, the vehicle has now learned the PasslockTM Sensor Data Code and/or password. With a scan , clear any DTCs if needed, DTCs will self clear after 100 ignition cycles

thank you i will try and feed you back

the car started with 2200 Ohm resistor then Passlock relearn
can i get the Resistance value for other CHEVE GM cars plz ?
thank you
