Car Key Cutting Explained

Cutting the car key is more than just bending a piece of metal. It is a sophisticated process that guarantees security, efficiency and the longevity of keys.

It is not unusual to lose your car keys or even break it in the lock. You'll need a replacement car key to ensure that you are able to drive your vehicle at all times.

Transponder Keys

If your cheap car key cutting was manufactured within the last 20 years, it is likely to have a transponder chip. These microchips are situated in the handle of the key and transmit a signal your vehicle's onboard computers when you use the key. The onboard computer scans the digital serial numbers in the chip and only allows the car to start if it's the correct one. This stops thieves from hijacking your vehicle since they'd need to be aware of the unique serial number.

The microchip inside your car keys transmits an low-level radio signal to the receiver inside the car. This radio signal activates the microchip that then transmits the code to the onboard computer of the car. The car will be able to recognize this code and only allow it to start only if it is the correct one. This stops the use of "hot wiring" and other methods of stealing cars.

Car keys with chips can be made at locksmiths that offer these services. They are also available at a few automotive key cutting stores, such as AutoZone.

Another kind of car key that is difficult to duplicate is the VATS (vehicle anti-theft system) key. These keys feature a black resistor in the key blade that is programmed with one of 15 possible values to stop them from starting a vehicle that it's not intended to. These keys are more expensive to purchase and require a special key programming machine that is only located at certain locksmiths.

Keys to VATS

Before transponder keys and vehicles with computer chips built in to control the ignition, GM used a system called VATS (Vehicle Anti-Theft System). VATS utilizes a key that has an internal resistor to ensure that the correct key was used to start the car. The black VATS pellet located in the middle of the VATS key isn't an electronic chip like the ones found on modern smart keys, it is simply a block of carbon appropriately sized to have an exact electrical resistance.

GM employed 15 different resistances for VATS pellets and connected them to key blades so that, when the key is turned on, a coded signal is sent to module. If the signal matches the one of the transistors in a VATS pellet, then the relay in starter circuit will activate and the engine will start to run. This isn't a way to make a car safe from theft however it can delay the theft by at least 15 to 20 minutes.

Unfortunately, after a significant amount of usage, the VATS module in your car could start to wear out. The two small wires in the ignition are moved every time the key is inserted. As time passes the wires could start to break. Once enough of the wires are broken, the signal to the module gets lost and it won't start the car.

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

This is a great opportunity to test a brand new key and see if it works in your car. Just be sure to remove the key from the ignition before you begin testing it, or else the new key could have an incorrect VATS value and not work in your vehicle.
