The typical resistor value needed to bypass a GM PassLock system is between 1.5k ohms and 13k ohms, depending on your vehicle's specific PassLock sensor reading. You must measure the resistance across the yellow and black wires at the ignition switch when the key is in the "on" position, then use a resistor of matching value to bypass the system. Common values are 2.2k ohms or 5.6k ohms, but always measure your vehicle's exact resistance for best results.
