Passlock Delete Tune

Whether you are encountering an issue with the security system that is preventing your engine from starting or you are swapping a GM engine into an old hot rod, we can help.

This service disables the Passlock System (otherwise known as VATS or Theft Deterrent) within the PCM on most 1998-2013 GM Trucks and SUVs. This option will require the PCM from the vehicle to be shipped to us to be updated. Please contact us for our mail-in form to include with your PCM.
