It is not unusual to lose keys to your car, or have them break through the lock. To ensure that you can always drive your vehicle you'll need to have a replacement key cut. Transponder Keys Transponder chips are likely to be fitted in vehicles built in the last 20 years. These chips are tiny microchips located in the key's handle that send signals to the car's onboard computer whenever you use it. The onboard computer is able to verify the serial number digitally of the chip prior to it allows the car to start. This helps prevent theft of cars, as thieves would need to know your unique serial number in order to be able to steal it. The microchip in your car key transmits a low-level radio signal to the receiver inside 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 if it recognizes this code. This prevents "hot wiring" or other methods to steal cars. Locksmiths who provide these services can make car keys with chips. They can also be purchased at some automotive retailers like AutoZone. These stores have a large variety of keys, and can help you find the appropriate one for your car. They can assist you in programming your vehicle's chip which is needed to use the device.

This technology is most common in high-end cars however, it is now available in a wide range of low-cost models. The VATS (vehicle-anti-theft system), key is another type of key that is difficult to duplicate. The keys have a resistor that is black on the blade of the key. It can be programmed with one of 15 possible values to stop it from starting a car that's not intended to. These keys are more expensive to buy and require a special key programming machine that can only be located at certain locksmiths. VATS Keys Before transponder keys or cars with computer chips that control the ignition, GM used a system known as VATS (Vehicle Anti-Theft System). VATS uses a key with an internal resistor to ensure that the correct key was used to start the car. The VATS black pellet that is inside the middle of a VATS key is not a chip like those used in modern smart keys, it's simply a block of carbon properly sized to carry an electrical resistance that is specific to. GM employed 15 different resistance values for the VATS pellets. They attached the key's blade, so that when the key is turned in the ignition the coded signal is transmitted to the module. If the signal is in line with that of the transistor in a VATS pellet then the relay in the starter circuit will be activated and the engine will start to run. This doesn't make a vehicle secure from theft, but it will delay the thief by at minimum 15 to 20 minutes. After a long period of use, the VATS module can 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. When enough wires break, the signal to the module is lost and the module won't be able to start the car. You can resolve this issue at home by decoding your VATS key. You'll need a multimeter and an indicator chart to determine the resistance value of your key, but it's not that difficult. You can find 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 good way to test a new key to see whether it works in your vehicle. Make sure you remove the key from the ignition before you begin testing it, or else the new key could have an incorrect VATS value and not work in your car.
