Immobilizer Bypass

We offer Immobilizer Bypass units for most vehicles that have a PATS (Chip in the key) at This kit utilizes a spare key (or just the plastic handle part of the key) which is locked in a box and secured in the dashboard of the vehicle. We also have a limited number of Passlock Immobilizers.

If you do not want to purchase an Immobilizer Bypass kit, you will find common methods to accomplish the same thing by using relays.
