Car Key Cutting Explained

Car key cutting is more than simply shaping an object of metal. It is a complex process that guarantees safety, functionality and long-term use of the keys.

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

Transponder Keys

Transponder chips are likely to be installed in cars built within the past 20 years. These microchips are in the key's handle and send a signal to the onboard computers in your vehicle when you turn the key. The onboard computer reads the digital serial number inside the chip and allows the car to start if it is the correct one. This prevents car thieves from hijacking your vehicle because they'd have to be aware of the unique serial number.

The microchip in your car keys transmits a low-level radio signal to the car's receiver. The radio signal activates the microchip, which then transmits an informational 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 correct one. This prevents the use of "hot wiring" and other methods of taking cars.

Car keys with chips can be made by an authorized locksmith who offers these services. They can also be purchased at a few automotive stores, such as AutoZone. Those stores carry a huge selection of keys and can assist you in choosing the appropriate one for your car. They can even assist you to programme the chip into your vehicle, which is essential to make it work.

There are also laser cut keys, which are more secure than traditional flat keys. These keys have an cylinder for locking that is much harder to pick, and they can only be duplicated using expensive laser key cutting machines or specially designed software. This type of technology is typically found in luxury cars, but is now available on a variety of affordable models.

The VATS (vehicle-anti-theft system) key is another type of key that's difficult to duplicate. They come with a resistor black on the blade of the key. It can be programmed to any of fifteen possible values to prevent it from starting a vehicle that's not designed to. These keys are more expensive to buy and require a special key programming machine that can only be located at certain locksmiths.

Keys to VATS

Before the advent of transponder keys and automobiles with built-in 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 cutting business was used to start the car. The black VATS Pellet that is located in the middle of the VATS Key is not a smart chip like those present on modern keys. It's just carbon or a block which is sized to provide an electrical resistance.

GM used 15 different resistance values for the VATS pellets and connected the key's blade so that when the key is turned in the ignition a coded signal will be transmitted to the module. If the signal matches that of the transistor in a VATS pellet then the relay in starter circuit will turn on and the engine will start to run. This does not make a car burglar-proof, but it can delay thieves for at least 15 to 20 minutes.

After a lot of usage the VATS module may start to wear out. The two small wires in the ignition are moved every when the key is introduced. As time passes the wires could begin to break. When enough wires are broken the signal to the module gets lost and the module won't be able to start the car.

The good news is that you can solve this problem yourself at home by decoding your own VATS key. You'll need a multimeter and a chart to determine the resistance value of your key, but it's not that difficult. All you have to do is place one of the leads of your ohm meter onto the prongs made of metal sticking out on both sides of the key, then examine the display of your ohm meter to determine the resistance of your key.

This is also a good way to test the new key to determine whether it works in your car. Remove the key from the ignition first before you test it. Otherwise the key may have an incorrect VATS and not work in your car.

They are usually paired with remote start hacks that allows thieves access to your vehicle's settings by the transmission of a fake signal by another transmitter nearby.

To protect a smart fob you can put it in a casing made of metal or put it in an RFID blocking case. This will prevent the transmission of these signals. However, the necessity of removing the key fob from its protective case each time you use it undermines the convenience of the technology.

Modern keys come with advanced features, such as encryption and anti-theft mechanisms. Encryption ensures that only the correct key cutting places is used to open your vehicle making it much more difficult for thieves to duplicate or pick locks. Transponder chips are another security feature that prevents theft. They are embedded into the key and connect to your vehicle.
