Transponder Keys Transponder chips are likely be installed in cars built in the last 20 years. These microchips are in the handle of the key and transmit a signal to the onboard computers in your vehicle when you press the key. The onboard computer examines the serial number of the chip before it allows the car to start. This helps prevent theft of cars, as thieves would need to know your unique serial number to be able to take over it. The microchip in the key transmits a low-level signal to the receiver within the car. This radio signal activates your microchip which then transmits code to the onboard computer of the car. Suggested Site will recognize the code and only allow it to start when the key is the correct one. This will stop the use of “hot wiring” and other methods of stealing cars. Car keys with chips can be made by a locksmith that offers these services. They can also be bought at certain automotive stores like AutoZone.

These keys are more secure than flat keys because they have locks that are harder to pick. They can only be duplicated with expensive laser key cutting machines, or specialized software. This technology is more common in high-end cars, but it is now being used in a variety of affordable cars as well. Another kind of key for cars that is difficult to duplicate is the VATS (vehicle anti-theft system) key. The keys contain a resistor that's black on the blade of the key. It can be programmed to any of 15 possible values to stop it from starting a vehicle it's not intended to. These keys are more expensive to buy and require a specific key programming device that can only be found at a few locksmiths. VATS Keys Before the days of transponder keys and automobiles equipped with computer chips that control the car's ignition, GM used something called VATS (Vehicle Anti-Theft System). VATS utilizes a key that has an embedded resistor to verify that the correct key was used to start the car. The black VATS Pellet that is located in the middle of the VATS Key isn't a smart chip as used on the majority of modern keys. It's just a block or carbon that is sized to hold an electrical resistance. GM employed 15 different resistances for the VATS Pellets and attached the key blades to them so that when the key was turned in the ignition the key blades transmit a coded message to module. If the signal matches 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 a thief for at least fifteen to twenty minutes. Unfortunately, after a significant amount of use the VATS module in your car can start to wear out. The two wires inside the ignition are moved every time the key is introduced. As time passes the wires can begin to break. When enough wires have been broken the signal is lost to the module and the car will not start. You can solve this problem at home yourself by decoding your VATS code. You'll require a multimeter and a chart to determine the resistance value of your key, but it is not that difficult. You can determine the resistance value by placing one of the leads on the prongs made of metal on both sides of your key. This is also a great way to test a new key to see whether it works in your vehicle. Make sure you remove the key from the ignition prior to testing it, as the new key could be displaying an incorrect VATS value and may not work in your car.
