C4 Corvette 1986-1989 Security Override System - 15 VATS Code Options

VATS stands for Vehicle Anti-Theft System. It is commonly referred to as PassKey. The VATS module does most of the security work. It is the brains of the entire system. The VATS module "reads" the resistance thru the contacts in the lock cylinder and the related wiring. If your key throws an incorrect code, your VATS will engage and shut your vehicle down. This usually results in leaving you stranded. 

Our security override system will enable a sure start every time and help avoid expensive towing costs. The way it works is, it's a plug-in solution that simulates your correct key code and plugs into your factory wiring harness with no modifications. We use only genuine GM factory connectors, pins and TPA's.

You can find the value yourself with a meter, or you can have your local GM dealer measure the resistance on your computer key (it will be a 1 thru 15 value code). You will need this code when placing your order.
