Car Key Cutting Explained Cutting the car key is more than just bending a piece of metal. It is a complicated procedure that ensures security, functionality and longevity of keys. It is not unusual to lose your car keys or even have it break in the lock. To ensure that you can always drive your vehicle, you will need to have a replacement key cut. Transponder Keys Transponder chips are likely be fitted in vehicles built in the last 20 years. These chips are small microchips inside the key's handle which transmit an electronic signal to the car's onboard computer when you use it. The onboard computer examines the serial number of the chip prior to giving the car permission to start. This prevents thieves from hijacking your vehicle because they'd have to be aware of the unique serial number. The microchip inside the key sends a low-level signal the receiver within the car. The radio signal activates microchip, which then transmits an encoded code to the car's onboard computer. The car will recognize this code and only allow it to start only if the key is the right one. This prevents “hot wiring” or other methods to steal cars. Locksmiths who offer these services can design car keys with chips. They are also available at some automotive retailers like AutoZone. These stores have a wide selection of keys and can assist you in choosing the appropriate one for your vehicle. car key cutting can assist you in programming the chip in your vehicle, which is required for the device to function. You can also get laser cut keys, which are more secure than flat keys. These keys are more secure than traditional 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 type of technology is typically found in luxury vehicles, but it is now being used in many affordable models of automobiles as well. Another kind of car key that is hard to duplicate is the VATS (vehicle anti-theft system) key. The keys are black with a resistor in the key blade that is programmed with one of fifteen potential values to prevent them from starting a vehicle that it's not meant to. They are expensive and require an instrument for programming keys, which is only available at certain locksmiths. VATS Keys Before the advent of transponder keys and cars with built-in computer chips to control the car's ignition, GM used something called 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 the VATS key isn't an electronic chip like the ones used in modern smart keys, it is simply a piece of carbon that is sized appropriately to have a specific electrical resistance value. GM employed 15 different resistance values for the VATS pellets. They attached the key's blade, so that when the key is turned on the ignition, a coded signal is transmitted to the module. If the signal is in line with the one of the transistors in a VATS pellet then the relay in the starter circuit will activate and the engine will start to run. This doesn't make a car burglar-proof however it could delay thieves for at least 15 to twenty minutes. After a lot of usage, the VATS module can start to wear out. Each time a key is inserted into the ignition it reroutes two small wires within the ignition, and over time the wires can begin to break. Once enough of the wires break 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 issue yourself by decoding your VATS key. It's not difficult to determine the resistance of a key using a multimeter. All you have to do is put one of the leads of your ohm meter onto the metal prongs that are hanging out on both sides of the key, then read the ohm meter's display to determine the resistance of your key. This is a great way to test a new key and see whether it works in your vehicle. Remove the key from the ignition first before you test it. Otherwise the key could have an incorrect VATS and not function in your vehicle. Smart Key Fobs with Smart Keys Key fobs of today do more than just unlock or start cars.
