Car Key Cutting Explained

Cutting a car key is more than just bending metal. It is a complex procedure that ensures security, efficiency and the longevity of keys.

It is not uncommon to lose your car key or have it break off in the lock. You will need an alternative car key to ensure you can drive your vehicle at all times.

Transponder Keys

Transponder chips will likely be fitted in vehicles built in the last 20 years. These chips are small microchips inside the key's handle that send an electronic signal to the car's onboard computer when you are using it. The computer in the car detects the digital serial number in the chip and only allows the car to start if it's the correct one. This prevents car theft, as thieves would need to know your unique serial number in order to be able to take over it.

The microchip in the key transmits a low-level signal to the receiver within the car. This radio signal activates the microchip, which then transmits a code to the car's onboard computer. The car will be able to recognize this code and only allow it to start if it is the correct one. This stops "hot wiring" or other methods of stealing cars.

Car keys with chips can be made at a locksmith that offers these services. Some car dealers, like AutoZone offer keys with chips.

This technology is most commonly found in high-end cars however, it is now available in a wide range of low-cost models.

The VATS (vehicle-anti-theft system) key is another type of key that's difficult to duplicate. The keys are black with a resistor in the key blade that is programmed with one of fifteen possible values to stop them from starting a car that it's not designed to. They are expensive and require a key programming machine, which is only available at certain locksmiths.

VATS Keys

Before transponder keys and cars with computers built-in to control the ignition, GM used a system called VATS (Vehicle Anti-Theft System). VATS makes use of a key with an embedded resistor to verify that the correct key was used to start the car. The VATS pellet black in the center of a VATS key is not an electronic chip like the ones present in modern smart keys, it's simply a block of carbon properly sized to carry an electrical resistance that is specific to.

GM used 15 different resistance values for VATS pellets and attached them to the blade of the key so that when the key is turned in the ignition the coded signal is sent 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 begins to run. This doesn't make a car theft proof however it can delay the thief by at least 15 to 20 minutes.

After a long period of use the VATS module could begin to wear out. Each time a key is inserted into the ignition, it moves two very small wires inside the ignition, and with time, the wires may start to break. Once enough of the wires are broken the signal to the module gets lost and it won't start the car.

You can solve this problem at home yourself by decoding your VATS code. You'll require a multimeter as well as an indicator chart to determine the resistance value of your key, but it's not that difficult. All you have to do is place one of the leads of your ohm gauge on the prongs made of metal hanging out on both sides of the key, then look at the display of the ohmmeter to determine the resistance of your key.

This is a great method to test out a new key and see if it works in your car. Remove the ignition key first before you test it. In the event that it is not removed, the key may have an incorrect VATS and not work in your vehicle.
