A C4 VATS (Vehicle Anti-Theft System) Ignition Key Blank is a special key blank that is designed to work with the VATS system on a 1986-1996 Chevrolet Corvette (C4 generation). The VATS system is a security feature that was used on many GM vehicles in the 1980s and 1990s to help prevent theft.
The C4 VATS Ignition Key Blank is unique in that it contains a resistor pellet that is encoded with a specific value. When the key is inserted into the ignition switch, the VATS system reads the resistance value of the pellet and compares it to the value programmed into the vehicle’s computer. If the values match, the system allows the engine to start. If the values do not match, the system disables the starter and fuel pump, preventing the engine from starting.
The C4 VATS Ignition Key Blank is designed to be used as a replacement key for a C4 Corvette that uses the VATS system. If a key is lost or damaged, it is important to replace it with a key that contains the correct resistor value to ensure that the VATS system functions properly.
Overall, the C4 VATS Ignition Key Blank is an important component of the security system on a 1986-1996 Corvette, and it helps to ensure that only authorized individuals are able to start and drive the vehicle.
Some key sources supply the VATS pellet value in a 2 letter coding system. The chart below correlates the letter codes with the appropriate VATS code.

Rodney Boudonck (verified owner) –
Got exactly what I ordered promptly and took the original to a place to cut the key and they did it for free said didn’t have a way to charge me for it since I didn’t buy the blank from them.
Worked out good!
Buddy Brown (verified owner) –
Got exactly the key I needed. Took it to a dealership and was not charged to cut it.
