Car Key Cutting Explained Car key cutting is more than simply shaping the metal. It is a complex procedure that ensures security, efficiency and long-term use of the keys. It is not unusual to lose keys to your car, or have them break through the lock. You'll require a new car key in order to ensure that you are able to drive your car at all times. Transponder Keys Transponder chips are likely be installed in cars that were built in the last 20 years. These microchips are located in the handle of the key and send a signal to the onboard computers in your vehicle when you press the key. The computer on board reads the digital serial number in the chip and only allows the car to start if it's the correct one. This prevents car thieves from taking over your vehicle, as they would need to know the unique serial number. The microchip inside your car key sends an low-level radio signal to the car's receiver. The radio signal activates your microchip which then transmits instructions to the onboard computer of the car. The car will only begin when it recognizes the code. This prevents “hot wiring” or other methods to steal cars. Car keys with chips can be created at a locksmith that offers these services. They can also be bought at a few automotive stores, such as AutoZone. Those stores carry a huge variety of keys and can assist you in choosing the appropriate one for your vehicle. They can help you program the chip in your vehicle that is required for the device to function. You can also purchase laser cut keys, which are more secure than flat keys. These keys are more secure than flat keys due to having locks that are harder to pick. They can only be duplicated with expensive laser key cutting machines or specialized software. This technology is most commonly found in luxury cars however, it is now available on many affordable models. The VATS (vehicle-anti-theft system) key is another kind of key that is difficult to duplicate. These keys have a black resistor on the blade of the key that is programmed with one of 15 potential values to prevent them from starting a car that it's not meant to. These keys are costly and require an instrument for programming keys, which is only available at a few locksmiths. Keys to VATS Before the days of transponder keys and automobiles with built-in computer chips to control the ignition of the car, GM used something called VATS (Vehicle Anti-Theft System). VATS makes use of a regular key with a resistor pellet embedded in it to confirm that the correct key is being used to start the vehicle. The VATS pellet black inside the middle of a VATS key is not an electronic chip as found on modern smart keys, it's simply a carbon block properly sized to carry an exact electrical resistance. GM employed 15 different resistances for the VATS Pellets and connected them to key blades in a way that, when the key is turned on, a coded message is sent to module. If the signal is in line with the one of the transistors in a VATS pellet, then the relay in starter circuit will activate and the engine will start to run. This doesn't make a car secure from burglary however, it can deter the thief for a minimum of fifteen to twenty minutes. After a prolonged period of usage the VATS module may start to wear out. Every time a key is inserted into the ignition, it reroutes two small wires within the ignition, and, over time, the wires could begin to break. When enough wires have been broken the signal is lost to the module and the car will not start. The good news is that you can fix this issue at home by decoding your VATS key. It's not hard to determine the resistance value of a key with the multimeter. You can find the resistance value by putting one of the leads on the metal prongs on both sides of your key. This is a great way to test a brand new key and determine whether it works in your vehicle. Remove the ignition key first before you test it. In the event that it is not removed, the key may have an incorrect VATS and will not function in your vehicle.

They are typically used in combination with a remote-start hack that allows thieves to access your vehicle's settings by transmitting false signals from a nearby transmitter. One method to safeguard a smart key fob is to put it in a metal case or a specially designed RFID blocking case that blocks the transmission of these signals.
