Car Key Cutting Explained

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

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

Transponder Keys

Transponder chips will likely be fitted in vehicles 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 press the key. The computer in the car is able to verify the serial number of the chip prior to it allows the car to begin. This prevents thieves from hijacking your vehicle since they'd need to be aware of the unique serial number.

The microchip in the key transmits a low-level signal to the receiver within the car. The radio signal activates the microchip, which transmits an informational code to the car's onboard computer. The car will recognize this code and only allow it to start when the key is the correct one. This stops the use of "hot wiring" and other methods of taking cars.

Locksmiths that offer these services can design car keys with chips. They can also be bought at certain automotive stores like AutoZone. Those stores carry a huge variety of keys and can assist you in selecting the best one for your car. They can assist you in programming your car's chip which is needed for the device to function.

You can also get laser cut keys, which are more secure than traditional flat keys. They are more secure than flat keys due to the fact that they have locks that are harder to pick. They can only be duplicated with expensive laser key cutting equipment, or specialized software. This technology is more common in high-end cars, but it is now being used in a wide range of low-cost cars too.

The VATS (vehicle-anti-theft system) key is a different kind of key that is difficult to duplicate. These keys feature a black resistor in the key blade that is programmed with one of fifteen possible values to stop them from starting a vehicle that it's not meant to. They are expensive and require the use of a key programming machine which is only available through certain locksmiths.

Keys to VATS

Before the days of transponder keys and automobiles equipped with computer chips that control the ignition of a car, GM used something called VATS (Vehicle Anti-Theft System). VATS uses an ordinary key with a pellet of resistance embedded in it to confirm that the correct key is used to start the vehicle. The black VATS pellet located in the middle of the VATS key isn't an electronic chip as found on modern smart keys, it is simply a block of carbon appropriately sized to have an electrical resistance that is specific to.

GM employed 15 different resistance values for the VATS pellets. They attached them to the key's blade so that when the key is turned on the ignition, a 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 starts to run. This does not make a car burglar-proof however, it can deter the thief for a minimum of 15 to twenty minutes.

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

The good news is that you can solve this issue at home by decoding your own VATS key. It's not difficult to determine the resistance value of a key using a multimeter. All you need to do is place one of the leads of your ohm gauge on the metal prongs that are hanging out on both sides of the key, then read the ohm meter's display to determine the resistance of your key.

This method is also a good way to test a new key to determine if it will work in your car. Just be sure to remove the key from the ignition prior to testing it, as the new key may have an incorrect VATS number and will not work in your vehicle.
