Car Key Cutting Explained

Cutting the car key is more than just bending metal. It is a complicated procedure that ensures security, functionality and long-term use of keys.

It is not uncommon to lose keys to your car or even have them break into the lock. To ensure that you are able to always drive your vehicle, you will need to have a replacement key cut.

Transponder Keys

Transponder chips are likely be installed in cars built within the past 20 years. These microchips are in the key's handle and transmit a signal to your vehicle's onboard computers when you use the key. The computer on board reads the digital serial number within the chip and allows the car to start if it's the correct one. This prevents car theft since thieves need to know your unique serial number in order to be able to steal it.

The microchip in the key sends a low-level signal the car's receiver. The radio signal activates the microchip, and it then sends a code to the car's onboard computer. The car will be able to recognize the code and only allow it to start when it is the correct one. This prevents "hot wiring" or other methods to steal cars.

Car keys with chips can be created at an authorized locksmith who offers these services. They can also be purchased at certain automotive stores, such as AutoZone.

This type of technology is typically found in high-end cars however, it is now available on many affordable models.

Another type of key for cars that is hard to duplicate is the VATS (vehicle anti-theft system) key. These keys feature a black resistor on the key blade that is programmed with one of 15 potential values to prevent the spare car key cutting from starting that it's not meant to. They are expensive and require an instrument for programming keys, which is only available at certain locksmiths.

VATS Keys

Before transponder keys and cars that had computers built-in to control the ignition, GM used a system known as VATS (Vehicle Anti-Theft System). VATS utilizes a key that has an internal resistor to confirm that the right key was used to start the car. The VATS pellet that is black that is located in the middle of the VATS Key is not an electronic chip that is like those found on most modern keys. It's just carbon or a block that is sized to provide an electrical resistance value.

GM employed 15 different resistance values for the VATS pellets and connected them to the key's blade to ensure that, when the key is turned in the ignition, a coded signal is transmitted to the module. If the signal matches the one of the transistors in a VATS pellet, then the relay in starter circuit will turn on and the engine will begin to run. This doesn't make a car safe from burglary, but it can delay a thief for at least 15 to 20 minutes.

After a lot of usage the VATS module could begin to wear out. Each time the key cutting business is inserted into the ignition, it moves two tiny wires inside the ignition, and over time the wires could begin to break. Once enough wires are broken the signal to the module is lost and the module won't be able to start the car.

You can resolve this issue at home by decoding your VATS code. It's not difficult to determine the resistance of a key with a multimeter. You can determine the resistance value by putting one of the leads on the metal prongs on both sides of your key.

This is also a good way to test a new key to determine if it will work in your vehicle. Be sure to remove the key from the ignition before you begin testing it, as the new key could have an incorrect VATS value and not work in your vehicle.

Fortunately, some automakers have developed methods to shield smart mobile key cutting service fobs from common types of electronic threats like relay attacks. They are usually paired with remote start hacks that allows thieves access to your vehicle's settings via the transmission of a fake signal from another transmitter nearby.
