The safety of our vehicles is extremely important to all of us. VATS keys, introduced by GM in 1986, were one of the first keys to provide extra security measures, and therefore extra peace of mind that a vehicle is as safe as possible. VATS (Vehicle Anti-Theft System) keys were first used on Corvettes, because, as you can imagine, the sports car was a major target for thieves.
Since the invention of the VATS key did so well to reduce the number of stolen Corvettes, GM expanded the system to other models such as the Camaro, Firebird, and Cadillac Seville vehicles in their later models. VATS keys then became an industry standard as they appeared in other vehicles such as Buicks. The original VATS systems were popular through the early 2000s, and one of the last vehicles released with a traditional VATS system was the 2003 Firebird. The original VATS key systems paved the way for the levels of electronic vehicle security we have today.
There are a number of differences between traditional keys and VATS keys. Traditional mechanical keys provide just a basic level of security to vehicles. Two of the most common types of traditional mechanical keys are edge cut keys and side-winder keys.
Edge cut keys are the standard key variety that many vehicles have used for decades. The cuts are on the edge of the keys, and they can be copied by most standard key machines.
High security, or side-winder keys, offer a little more security than edge cut keys as they cannot be copied by standard key machines. In order to copy these keys, a particular type of machine must be used to engrave cut specifications into the key.
VATS keys are essentially the first electronic keys and, as such, provide a much-needed improvement in vehicle safety from their predecessors. VATS keys have resistors embedded in them, and when someone inserts a VATS key into the ignition of their vehicle, an electrical current runs through the resistor inside. The resistor value is read by a computer inside the car, and if it is not the same as the value in the computer’s memory, the car will not be able to start. This function provides extra security because a few minutes of stalling is plenty of time for a car thief to choose another vehicle to pursue.
Also, duplicating a VATS key is not as simple as going to a key copier at the store. In order to copy a VATS key, a locksmith will use a VATS interrogator to determine the resistance value of the key as it is important that they match, and then the cuts can be copied onto the blank key.
Electronic keys have certainly come a long way since the release of the original VATS keys in the mid ‘80s. Nowadays, many of us have remote buttons we can use to lock and unlock our cars at the very least. Many vehicles now have keypads on which you can enter a code to unlock your car, and even push-to-start buttons that render a standard key unnecessary.
