• What is a Passlock / Passkey / VATS system?

  It’s GM’s factory engine immobilizer. Depending on the year/model it may be called Passkey, VATS, Passlock, etc., but they all work by checking a signal from the key/lock and then sending an “OK” signal to the engine computer to allow fuel.

• What is a Passlock bypass resistor?

  A resistor “bypass” is a partial fix that only tricks the system into thinking the right key is present. It still relies on the original theft‑deterrent module to send the final “OK” signal, so when that module fails, the resistor trick stops ...

• Why resistor tricks and cheap bypass kits don't work permanently?

  Because they leave the weakest, most failure‑prone part—the theft‑deterrent module (sometimes inside the BCM/IPC)—still in control. When that module finally fails, the car goes back to no‑start, even if a resistor or “bypass” was installed.

• Will I still need a new theft‑deterrent module or BCM?

  If the problem is the factory immobilizer, then no—you do not need a new theft‑deterrent module (TDM) or BCM. The PRO Module is designed as a full bypass of the immobilizer function and, when installed correctly on a supported vehicle, it completely ...

• When will my order be shipped?
