Car Key Cutting Explained

Cutting keys for cars is more than just bending a piece metal. It is a complicated procedure that ensures security, efficiency, and longevity of the keys.

It is not uncommon to lose your car keys or have it break off in the lock. To ensure that you can always drive your car you'll need to have a replacement key cut.

Transponder Keys

If your car was constructed in the past 20 years, it is likely that it has a transponder chip. These microchips are located in the key's handle and send a signal to the onboard computers of your vehicle when you use the key. The computer in the car scans the digital serial numbers within the chip and allows the car to start if it's the correct one. This prevents thieves from stealing your car because they'd have to be aware of the unique serial number.

The microchip inside your car key transmits a low-level radio signal to the receiver inside the car. This radio signal activates your microchip, which transmits a instructions to the onboard computer of the car. The car will only begin when it recognizes the code. This will stop "hot wiring" or other methods of stealing cars.

Locksmiths who offer these services can make car keys with chips. Some automotive retailers such as AutoZone offer keys with chips.

Laser cut keys are more secure than flat keys. These keys have a lock cylinder that is much harder to pick, and are only duplicated using expensive laser key cutting machines or specially designed software. This technology is more prevalent in high-end vehicles, however it is now available in many affordable models of cars as well.

Another kind of car key cutting open now that's hard to duplicate is the VATS (vehicle anti-theft system) key. These keys have a black resistor on the key blade that is programmed with one of 15 potential values to prevent them from starting a vehicle that it's not designed to. These keys are more expensive to purchase and require a special key programming machine that is only located at certain locksmiths.

VATS Keys

Before transponder keys or cars that had computer chips built in to control the ignition, GM used a system called VATS (Vehicle Anti-Theft System). VATS utilizes a standard key that has a resistor pellet embedded in it to confirm that the correct key is being used to start the car. The black VATS Pellet that is located in the middle of the VATS Key is not a smart chip as found on most modern keys. It is simply carbon or a block that is sized to have an electrical resistance value.

GM employed 15 different resistance values for the VATS pellets. They attached the key's blade to ensure that, when the key is turned on the ignition, a coded signal is sent to the module. If the signal matches that of the transistor in a VATS pellet then the relay in the starter circuit will be activated and the engine will begin to run. This doesn't make a car burglar-proof however, it can deter a thief for at least 15 to 20 minutes.

Unfortunately, after a significant amount of usage, the VATS module in your car could begin to wear out. Each time a key is inserted into the ignition it reroutes two small wires inside the ignition, and with time, the wires can start to break. When enough wires have been broken, the signal is lost to the module and the car will not start.

You can solve this issue at home by decoding your VATS key. You'll require a multimeter as well as a chart to determine the resistance value of your key, but it's not difficult at all. You can find the resistance value by placing one of the leads on the prongs made of metal on both sides of your key.

This can also be a good method to test a new key to see whether it works in your vehicle. Be sure to remove the key from the ignition prior to testing it, as the new key could have an incorrect VATS value and may not work in your vehicle.

These are often utilized in conjunction with remote-start hacks that allow thieves to gain access to your vehicle's settings by transmitting a fake signal from another nearby transmitter.

One method of protecting the smart key fob is to keep it in a metal case or use an RFID blocking case that prevents the transmission of these signals. However, the necessity of removing the key fob from its protective case every time you use it undermines the convenience of the technology.
