Car Key Cutting Explained

Cutting a car key is more than just bending a piece metal. It is a complicated procedure that ensures safety, functionality and the longevity of keys.

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

Transponder Keys

If your car was manufactured within the last 20 years, it's likely to have transponder chips. These microchips are in the key's handle and transmit a signal to the onboard computers in your vehicle when you press the key. The onboard computer checks the serial number digitally of the chip prior to it allows the car to begin. This prevents car theft since thieves need to know your unique serial number in order to be able to steal it.

The microchip in your car key sends a low-level radio signal to the receiver inside the car. The radio signal activates your microchip which then transmits code to the computer onboard of the car. The car will recognize this code and only allow it to start only if it is the correct one. This will stop "hot wiring" or other methods to steal cars.

Locksmiths who provide these services can design car keys with chips. They can also be bought at some automotive retailers like AutoZone. These stores have a wide selection of getting keys cut and can help you get the right one for your car. They can assist you in programming the chip in your vehicle which is needed for the device to function.

There are also laser cut keys that are more secure than traditional flat keys. These keys have the lock cylinder, which is much more difficult to pick, and they are only duplicated using expensive laser key cutting machines or with specialized software. This technology is more prevalent in high-end vehicles, however it is now accessible in a wide range of low-cost cars as well.

The VATS (vehicle-anti-theft system) key cutting price is another kind of key that is difficult to duplicate. These keys have a resistor that is black on the blade of the key. It can be programmed with one of 15 possible values to prevent it from starting a car that's not designed to. These keys are costly and require an instrument for programming keys, which is only available through certain locksmiths.

VATS Keys

Before the advent of transponder keys as well as cars equipped with computer chips to control the ignition of a car, GM used something called VATS (Vehicle Anti-Theft System). VATS uses a key with a resistor embedded in it to confirm that the right key was used to start the car. The black VATS Pellet in the middle of a VATS Key isn't an electronic chip that is like those used on the majority of modern keys. It's just a block or carbon that is sized to provide an electrical resistance value.

GM employed 15 different resistances for VATS pellets and connected them to key blades in a way that, when the key is turned in the ignition a 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 will start to run. This doesn't make a car safe from burglary, but it can delay the thief for a minimum of 15 to twenty minutes.

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

You can resolve this issue at home yourself by decoding your VATS code. You'll require a multimeter and a chart to determine the resistance value of your key, but it's not difficult at all. All you need to do is put one of the leads of your ohm meter on the prongs made of metal visible on both sides of the key, and then look at the display of the ohmmeter to find out the resistance value of your key.

This method is also a great way to test a new key to see whether it will work in your vehicle. Make sure you remove the key from the ignition prior to testing it, as the new key may have an incorrect VATS value and may not function in your car.
