Chevrolet Corvette VATS Disable / Delete Service

If your Chevrolet Corvette will not start due to a failed VATS key or ignition problem, the Vehicle Anti-Theft System (VATS) is often the cause. Our VATS disable and delete service permanently removes the immobilizer requirement from your ECM/PCM, allowing your Corvette to start and run without needing a resistor key or functioning VATS system.

What MoPower Can Offer

• Permanently remove VATS security from your Chevrolet Corvette ECM/PCM
• VIN rewritten back into the ECM/PCM for a seamless factory match
• Fixes no-start conditions caused by failed keys, ignition, or swapped computers
• Plug-and-play PCM install – no dealer key programming required

How VATS Works

Chevrolet introduced the Vehicle Anti-Theft System in the Corvette to deter theft by requiring a resistor chip in the ignition key. If the ECM/PCM does not detect the correct resistance, it disables fuel and spark, preventing the engine from starting. Our VATS delete service clears this lock, restoring normal plug-and-play operation.

• Failed or missing VATS keys cause no-start issues
• Deleting the system allows normal use of replacement or non-VATS keys
• Applies to 1986–2004 Chevrolet Corvette models equipped with VATS

Security Light Woes

After VATS delete, the security light may remain illuminated on some Corvette dashboards. If this happens, the only solution is to remove the bulb or LED from the cluster.

Plug-and-Play Installation

Most customers can install a VATS-deleted ECM/PCM with no additional programming. In rare cases, a global DTC clear may be required before the car will start.
