Car Key Cutting Explained

Car key cutting is more than just shaping the metal. It is a complicated procedure that guarantees security, function and long-term use of keys.

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

Transponder Keys

If your car keys cut by code was manufactured in the past 20 years, it's likely that it has a transponder chip. These chips are small microchips inside the key's handle which transmit signals to the car's onboard computer whenever you use it. The computer in the car checks the serial number of the chip before giving the car permission to begin. This prevents car theft since thieves need to know your unique serial number in order to have a chance at hijacking it.

The microchip in your car key transmits an unintentional radio signal to the receiver inside the car. The radio signal activates the microchip, which transmits a code to the car's onboard computer. The car will be able to recognize this code and will only allow it to start only if the key is the right one. This prevents "hot wiring" or other methods of stealing cars.

Locksmiths that offer these services can create keys for cars with chips. They can also be bought at some automotive retailers like AutoZone. They have a vast range of keys and will assist you in selecting the best one for your car. They can even help you program the chip to your vehicle, which is necessary to make it work.

Another type of car key that is hard to duplicate is the VATS (vehicle anti-theft system) key. They contain a resistor that's black on the blade of the key. It can be programmed to one of fifteen possible values to stop it from starting a vehicle it's not designed to. They are expensive and require an instrument for programming keys, which is only available at certain locksmiths.

VATS Keys

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 a resistor embedded in it to confirm that the right key was used to start the car. The VATS pellet in black in the middle of a VATS Key is not a smart chip as found on most modern keys. It is merely carbon or a block that is sized to provide an electrical resistance.

GM employed 15 different resistance values for VATS pellets and connected the key's blade, so that when the key is turned on in the ignition the coded signal is transmitted to the module. If it matches 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 does not make a car secure from burglary, but it can delay a thief for at least fifteen to twenty minutes.

After a long period of use, the VATS module can begin to wear out. Every time a key is inserted into the ignition, it moves two tiny wires within the ignition, and with time, the wires may start to break. If enough wires are damaged the signal is lost to the module and the car won't begin.

The good news is that you can solve this issue yourself by decoding your own VATS key. It's not hard to determine the resistance of a key with a multimeter. All you have to do is place one of the leads of your ohm meter on the prongs of metal that are sticking out on both sides of the key, and then look at the display of the ohmmeter to determine the resistance value of your key cutting price.
