Keys
Most modern cars require a transponder key to operate. This provides security and protection against theft. These keys must be programmed to the specific vehicle and its features by a licensed locksmith or dealer. It's costly to replace them if they become lost, so it's better to have spares in your possession. You can also find replacement key fobs on various websites and in many brick-and mortar auto shops. How can you be sure that the one you bought is genuine? Can you tell whether the unit is programmed to work with a different vehicle or if it could be programmed differently?
If you want to program an entirely new key, the first step is to make sure that your car is running. Insert the key you want to reprogram into the ignition without turning it. There are only a couple of seconds before the car's system resets the commands and exits programming mode. Therefore, it is essential to move quickly and not be able to wait between steps. To prevent this from happening, shut off the engine. like it can check the car's system by turning the key to the "on" position and then back to the "off" position. The door locks should be able to cycle, and you will hear a chime signalling that the process was successful.
Certain newer vehicles utilize rolling keys to stop thieves from using stolen keys to start the vehicle. The feature is still vulnerable to a technique called replay attack. It allows thieves to record and then duplicate the signal generated by the key fob of the vehicle to unlock the car. To counter this, manufacturers have added a security feature called CAN bus protocol to prevent attacks on hacking.
Some manufacturers also use special encryption on their key fobs which cannot be decoded by an ordinary program. These types of vehicles require programming by a professional. Therefore, you should only attempt this procedure with someone who has experience with electronic devices. Refer to the manual for your car or go to the website of the manufacturer to learn how to program it. The steps to follow will differ according to the type of vehicle.
Transponder chips
Transponder chip car keys require a special reprogramming to work. While any hardware store can cut keys for you, the biggest issue is how to integrate it to work with the specific car you own. The key must be programmed to match the exact identification code on your car, otherwise it won't start.
Transponder chips are a typical feature of modern cars and are designed to prevent car theft. The chip is a microcircuit which transmits a radio-frequency signal when the ignition key is inserted. The car is able to detect the signal and starts the engine only if it matches the one programmed into the vehicle. The car will also shut down if a frequency is invalid. This makes it more difficult for thieves who are not experienced to connect a vehicle with hot wires and start it.
The chip and the key are connected via the circuit board which includes an induction coil. When the key is placed in the ignition the magnetic field is generated around the transponder. This creates a signal which is received by the coil and sent to the key identification number. The key's identification number is then sent back to the car, and the engine starts if the identification number matches.
There are many ways to program a transponder, however all require a special tool. These tools can be bought on the internet or at most auto locksmiths. These tools aren't inexpensive, but they are vital for programming the chip in your car.
You could also use a resettable key that was programmed for a different vehicle. In this instance you'll need to make sure that the key is not damaged or the transponder has been altered in any way. The chip can be read by using a scanner or a computer equipped with an USB connector.
Reprogramming the transponder key is simple, but it requires an expertly designed software and scan tool. It is best to consult an auto locksmith for assistance for those who are new to the process. You should also avoid buying second-hand keys, since they're likely to be programmed and won't work with your car.
