Reprogramming Car Keys
Transponder keys are believed to be more secure for cars and are more difficult to copy by thieves. However, a key may need to be reprogrammed when it becomes damaged or lost.
You can change the key fobs you own, but you must know the correct process. To get the best results, you should have the following items:
Keys
Modern cars require a transponder key in order to operate. This is a security feature and anti-theft protection. The keys must be programmed to your specific vehicle and its systems by a certified locksmith or dealer. They are expensive to replace if lost, so you should keep extras handy. You can also find replacement keys fobs in various online stores and in many brick-and-mortar auto shops. But how do you know that the new one you have bought is genuine? Are you able to tell if the unit has been programmed to work with a different vehicle, or if it can be programmed differently?
To program a new car key you must first ensure that your vehicle is operating. Insert the key you wish to program into the ignition without turning it. You have only a few seconds left before the system will reset all commands and leaves the programming mode. It is essential to be quick and don't be patient between each step. To avoid this happening, turn off the engine. Change the key from "on" to "off" to test the system. There should be a chime to indicate that the process was successful. The door locks will be able to cycle.
Some newer cars use a rolling key technology that keeps thieves from using a stolen car's key to open it. The feature is still vulnerable to a technique dubbed replay attack. It allows thieves to record and then reproduce the signal received from the vehicle key fob to open the car. To stop this, manufacturers added the security feature known as the CAN bus protocols to prevent hacking.
Some manufacturers also use special encryption on their key fobs that cannot be decoded with an easy program. These kinds of cars require programming by a professional, and you should only try this only if you've worked with electronic devices. Refer to the manual for your car or visit the manufacturer's website to learn how to program it. The steps will vary depending on the model of vehicle.
Transponder chips
Car keys with transponder chips require a special programming to function. While any hardware store can cut a new key for you, the biggest challenge is making it function with your specific car. The key you reprogrammed needs to match the exact identification number of your car or else it won't be able to start the engine.
Transponder chips, which are used to protect cars from theft are a standard feature of modern automobiles. The chip is a small microcircuit which transmits a radio-frequency signal when the ignition key is inserted. The car can detect the signal and begins the engine only if the signal is in line with the original one that was programmed into the vehicle. The vehicle is also programmed to shut down when it detects an incorrect frequency. This makes it much harder for car thieves with no experience to hot wire a vehicle and start it.
A circuit board equipped with an induction coil that connects the key to the chip. When the key is placed in the ignition the magnetic field is created around the transponder. This generates a signal, which is taken up by the coil and then transmitted to the key's identification number. The ID number of the key is then sent back to the vehicle, and if it is in line with the engine will start.
There are many ways to program a key transponder, however each requires a special tool. You can purchase these tools online or from most automotive locksmiths. These tools are not expensive, but they are essential to program your car's chip.
You may also use a resettable key that was programmed for another vehicle. In this case, ensure that the key isn't damaged or the transponder is not altered in any way. The chip can be read using a scanner, or a computer equipped with an USB connector.
Reprogramming the transponder key is simple, but it requires specialized software and a scan tool. If you're new to the process you should seek out the help of an auto locksmith. Also, avoid buying secondhand keys, as they are likely already programmed and will not work with your car.
