You'll need a new car key in order to ensure you can drive your car at all times. car keys cut and programmed If your car was manufactured in the past 20 years, it is likely that it has transponder chips. These chips are small microchips located in the key's handle which transmit signals to the car's onboard computer whenever you use it. Visit Web Page inside the chip and allows the car to start if it's the correct one. This prevents car thieves from stealing your car since they'd need to know the unique serial number. The microchip in the key sends a low-level signal the car's receiver. The radio signal activates your microchip that then transmits the instructions to the onboard computer of the car. The car will only begin only if it recognizes the code. This will stop “hot wiring” or other methods of stealing cars. Locksmiths that offer these services can create keys for cars with chips. They are also available at a few automotive stores, such as AutoZone. They have a huge selection of keys, and can assist you in finding the appropriate one for your car.

These keys are more secure than flat keys because they have locks that are harder to pick. They are only duplicated with expensive laser key cutting machines or specialized software. This type of technology is typically found in high-end cars, but it is now accessible in a variety of affordable automobiles as well. The VATS (vehicle-anti-theft system) key is another type of key that's 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 vehicle it's not designed to. These keys are more expensive to buy and require a specific key programming machine that can only be found at a few locksmiths. VATS Keys Before transponder keys or cars that had computer chips that control the ignition, GM used a system called VATS (Vehicle Anti-Theft System). VATS uses an ordinary key with 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 the VATS key isn't an electronic chip as found on modern smart keys, it is simply a carbon block appropriately sized to have a specific electrical resistance value. GM used 15 different resistance values for VATS pellets and connected them to 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 the resistance value of the transistor in the VATS pellet, the relay in the starter circuit is activated and the engine will start to run. This doesn't make a car safe from burglary, but it can delay thieves for at least fifteen to twenty minutes. After a prolonged period of usage the VATS module may start to wear out. The two small wires in the ignition are moved each time a key is introduced. As time passes the wires can begin to break. If enough wires are damaged the signal goes out to the module and the car will not begin. The good news is that you can solve this issue yourself by decoding your VATS key. You'll require a multimeter as well as a chart to find out the resistance value of your key, but it is not difficult at all. You can find the resistance value by placing one of the leads on the prongs of metal on both sides of your key. This is a great way to test a brand new key and see whether it will work in your vehicle. Be sure to remove the key from the ignition before you begin testing it, or else the new key could be displaying an incorrect VATS number and will not work in your car.

Certain automakers have devised methods to protect smart key fobs from common electronic attacks, like relay attacks. These are often used in combination with a remote-start hack that allows thieves to gain access to your vehicle's settings by transmitting an untrue signal from a nearby transmitter.
