Reprogramming Car Keys
Transponder keys for car keys are believed to make vehicles safer and are more difficult for thieves to duplicate. A key may have to be reprogrammed in event that it is damaged or lost.
You can reprogram your key fobs at home, but you must know the right process. For the best results, you should have the following items:
Keys
Modern cars require a transponder key in order to operate. This gives security and anti-theft protection. The keys have to be programmed to your specific vehicle and its features by an authorized locksmith or dealer. It is expensive to replace them if they become lost, so it's better to keep extras on hand. You can also find replacement key fobs at various online stores and in many brick-and mortar auto shops. How can you be sure that the one you purchased is genuine? Can you tell whether it has been programmed for a different vehicle or if it is able to be reprogrammed for yours?
To program a new car key you must first verify that your vehicle is operating. Insert the key you wish to reprogram into the ignition, but do not turn it. You will only have a few seconds before the car's system resets the commands and leaves programming mode. It is crucial to move quickly and don't be patient between each step. Turn off the engine to stop this. You can test the car's system by turning the key to the "on" position and then back to the "off" position. The door locks should cycle and you will hear a chime signalling that the process has been successful.
Certain newer vehicles have rolling key technology, which prevents thieves from using stolen cars' key to open it. This feature is still susceptible to a technique dubbed a replay attack. It allows thieves to record and then duplicate the signal generated by the vehicle key fob to open the car. To combat this, manufacturers introduced the security feature known as the CAN bus protocols to ward off hacking.
Certain manufacturers employ a specific encryption on their keys, which cannot be decoded by an ordinary program. It is best to only attempt this method if you have experience is in electronics. It is recommended to read the owner's manual of your vehicle or search for the manufacturer on the internet, since the steps differ based on car model.
Transponder chips
Car keys with transponder chips require a special reprogramming to work. While any hardware store can cut a new key for you, the main problem is to make it work in conjunction with your particular car. A reprogrammed key will need to match the specific identification number of your car or else it won't be able to start the engine.
Transponder chips are a common feature of modern automobiles and are designed to guard against car theft. The chip is a microcircuit which emits a radio frequency signal when the key is put into the ignition. The car detects the signal, and starts the engine only if the signal matches the original that was programmed into the vehicle. The car also shuts down if the frequency is not valid. This makes it more difficult for novice car thieves to connect a vehicle with hot wires and start it.
A circuit board with an induction coil connects the chip to the key. When the key is placed in the ignition it creates a magnetic field generated around the transponder. This generates a signal, which is received by the coil and sent to the key identification number. The key's identification code is returned to the car, and the engine starts when the identification number matches.
There are many ways to program a key transponder, but all require the use of a specific tool. You can buy these tools online or from most automotive locksmiths. They are not cheap, but they are crucial for programming the chip to your vehicle.
You may also use a unreprogrammable key that was programmed for an alternative vehicle. In this case you'll need to make sure that the key is not damaged or that the transponder has been altered in any way. To accomplish this, you'll need a scanner or a computer with an USB port to identify the chip and establish its identity.
Reprogramming an transponder is a simple procedure, but requires specific software. It also requires an scanner tool. If you're just beginning you should seek the assistance of an auto locksmith. Avoid buying used keys because they might already be programmed, and they won't work with your car.
EZ Installer
For decades, car owners who needed to replace their key fob had no other alternative than to visit a dealership to get their key linked to their vehicle.
