Reprogramming Car Keys
Transponders in car keys are believed to make vehicles more secure and harder for thieves to duplicate. A key may have to be reprogrammed in event that it is damaged or lost.
You can reprogram key fobs yourself, but you must know the correct procedure. For the best results, you'll need the following items:
Keys
Nearly all modern vehicles require some kind of transponder fob or transponder keys to operate, ensuring security and anti-theft protection. The keys have to be programmed to the specific vehicle and its features by a certified dealer or locksmith. It's costly to replace them if they become lost, so it's a good idea to keep extras on hand. You will also find replacement key fobs on various websites and in many brick-and-mortar auto shops. How do you ensure that the one you purchased is authentic? Do you know whether the unit is programmed to work with a different vehicle or if yours can be programmed differently?
If you're looking to program a new key, the first step is to ensure that your vehicle is running. Insert the key you'd like to reprogramme into your ignition, but don't turn it. You will only have a few seconds before the car's system resets commands and exits programming mode. It is essential to move quickly and do not be patient between each step. Turn off the engine to avoid this. You can test the car's security system by turning the key to the "on" position, then back to the "off" position. The door locks should be able to cycle, and you'll hear a chime to indicate that the process has been successful.
Certain newer vehicles have rolling key technology, which keeps thieves from using a stolen car's key to open it. The technology is still susceptible to a technique known as replay attack which allows thieves to record the signal received from the vehicle's key fob, then reproduce it to unlock the car. To stop this, manufacturers added security features known as the CAN bus protocols to prevent hackers from gaining access to the vehicle.
Certain manufacturers also employ special encryption on their key fobs that cannot be decoded with an easy program. These types of vehicles will need to be programmed by a professional, so you should only attempt this process with someone who has experience with electronic devices. Consult your car's manual or go to the website of the manufacturer to learn how to program it. The steps will vary depending on 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 main problem is to make it work to work with the specific car you own. A reprogrammed key will need to match the specific identification number of your vehicle otherwise it won't even start the engine.
Transponder chips are a standard feature in modern cars and are designed to prevent car theft. The chip is a small microcircuit that transmits a radio-frequency signal when the ignition key is inserted. The car then scans for the signal and then starts the engine in case it matches the original one that was programmed into the vehicle. The car is also programmed so that it will shut down when it detects an incorrect frequency. This makes it more difficult for novice car thefts to wire a vehicle hot and then start it.
The key and the chip are connected via the circuit board which includes an induction coil. When the key is placed in the ignition it creates a magnetic field around the transponder. This produces a signal which is taken up by the coil, which transmits it to the key's identification number. The ID number of the key is sent back to the vehicle and if it is in line with the engine will begin to run.
There are many ways to program a transponder, but each requires a special tool. You can buy these tools online or from most locksmiths for cars. These tools are not inexpensive, but they are vital to program your car's chip.
You can also use a reprogrammable transponder key that has been previously programmed for another vehicle. In this instance you'll need sure that the key has not been damaged or the transponder has been altered in any way. You can read the chip by using a scanner or a computer with an USB connector.
Reprogramming a transponder is a simple process, but requires special software. It also requires an scanner tool. If you're new to the process, it's best to seek the assistance of an auto locksmith. You should also avoid buying second-hand keys, since they're likely to be programmed and will not work with your car.
