Transponder Keys

If your car was manufactured in the last 20 years, it's likely to have transponder chips. These microchips are situated in the handle of the key and key cutting for cars transmit a signal to your vehicle's onboard computers when you turn the key. The onboard computer detects the digital serial number within the chip and allows the car to start if it is the right one. This helps prevent theft of cars, as thieves would need to know your unique serial number in order to be able to take over it.

The microchip inside your car keys transmits a low-level radio signal to the receiver inside the car. The radio signal activates the microchip, which then transmits an informational code to the car's onboard computer. The car will only start only if it recognizes the code. This prevents the use of "hot wiring" and other methods of theft of cars.

Locksmiths who offer these services can create car keys with chips. They are also available at some automotive retailers like AutoZone.

These keys are more expensive to buy and require a special key programming device that can only be found at a few locksmiths.

VATS Keys

Before the advent of transponder keys and cars with built-in computer chips to control the ignition of the car, GM used something called VATS (Vehicle Anti-Theft System). VATS makes use of a key with an embedded resistor to ensure that the correct key was used to start the car. The VATS pellet black located in the middle of a VATS key is not an electronic chip like the ones found on modern smart keys. It is simply a block of carbon properly sized to carry a specific electrical resistance value.

GM used 15 different resistance values for the VATS pellets. They connected them to the blade of the key to ensure that, when the key is turned on in the ignition a coded signal will be transmitted to the module. If the signal is in line with the resistance value of the transistor in the VATS pellet, the relay in the starter circuit is activated and the engine starts to run. This doesn't make a car secure from theft, but it will delay the thief by at least 15 to 20 minutes.

Unfortunately, after a lot of use, the VATS module in your car may begin to wear out. The two small wires in the ignition move each time the key is introduced. Over time, the wires may begin to break. Once enough of the wires break the signal to the module gets lost and the module won't be able to start the car.

The good news is that you can fix this problem yourself at home by decoding your VATS key. It's not difficult to determine the resistance of a key by using the multimeter. You can determine the resistance value by placing one of the leads on the prongs made of metal on both sides of your key.

This is a great method to test out a new key and determine whether it will work in your car. Remove the key from the ignition first before you test it. Otherwise, the key may have an incorrect VATS, and will not work in your vehicle.
