Car Key Cutting Explained

Car key cutting is a lot more than just shaping the metal. It is a complicated procedure that ensures safety, functionality and longevity of keys.

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

Transponder Keys

If your car was constructed within the past 20 years, it's likely to have transponder chips. These microchips are in the key's handle and send a signal to the onboard computers in your vehicle when you press the key. The onboard computer examines the serial number digitally of the chip before it allows the car to begin. This prevents car thieves from taking over your vehicle, as they would need to be aware of the unique serial number.

The microchip in the key sends a low-level signal the receiver within the car. The radio signal activates your microchip that then transmits the code to the onboard computer of the car. The car will only begin when it recognizes the code. This stops the use of "hot wiring" and other methods of stealing cars.

Locksmiths who provide these services can design keys for cars that contain chips. Some car dealers, like AutoZone sell keys with chips. Those stores carry a huge selection of keys and can assist you in selecting the best one for your car. They can even assist you to programme the chip into your vehicle, which is essential to make it work.

Laser cut keys are more secure than flat keys. These keys are more secure than flat keys due to having locks that are more difficult to pick. They are only duplicated with expensive laser key cutting machines or with specialized software. This technology is most common in luxury cars however, it is now available in a wide range of low-cost models.

Another type of car key that is 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 possible values to stop the car from starting that it's not meant to. These keys are more expensive to buy and require a special key programming device that can only be located at certain locksmiths.

VATS Keys

Before transponder keys and cars with computer chips that control the ignition, GM used a system called VATS (Vehicle Anti-Theft System). VATS uses an ordinary key that has a resistor pellet embedded within it to verify that the correct key is used to start the vehicle. The VATS pellet black in the center of a VATS key is not a chip like those used in modern smart keys, it is simply a block of carbon properly sized to carry a specific electrical resistance value.

GM used 15 different resistances for the VATS Pellets. They attached them to key blades in a way that, when the key is turned on, the key blades transmit a coded message to the module. If the signal is in line with the signal of the transistor in a VATS pellet, then the relay in the starter circuit will turn on and the engine will start to run. This does not 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 use the VATS module in your car can start to wear out. The two small wires in the ignition are moved each time the key is introduced. Over time, the wires may start to break. Once enough wires are broken the signal is lost to the module and the car won't start.

You can resolve this issue at home by decoding your VATS key. 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 gauge on the prongs of metal that are visible on both sides of the key, then read the ohm meter's display to determine the resistance value of your key.

This is a great method to test out a new key and check whether it will work in your vehicle. Just be sure to remove the key from the ignition prior to testing it, otherwise the new key may have an incorrect VATS value and may not function in your car.
