Transponder keys are believed to be more secure for cars and harder to copy by thieves. Keys may need to be reprogrammed in event that it is damaged or lost.
You can change the key fobs you own but you must be aware of the correct procedure. You must have these things to ensure the best results:
Keys
Almost all modern cars require some kind of transponder key or fob in order to operate, ensuring security and anti-theft protection. The keys are programmed by a locksmith or authorized dealer to function with your car's systems and the specific model. They are costly to replace if they are lost therefore, you should keep extras handy. You will also find replacement key fobs at various online stores and in many brick-and-mortar auto shops. How can you ensure that the one you bought is genuine? Can you tell if the unit has been programmed to work with another vehicle, or if it can be reprogrammed?
If you're looking to program an entirely new key first, you need to ensure that your car is running. Insert the key you'd like to reprogramme into your ignition, but don't turn it. There are just a few minutes before the system will reset all commands and leaves the programming mode. It is important that you move quickly and don't be patient between each step. To avoid this happening, shut off the engine. Change the key from "on" to "off" to test the system. The door locks should cycle and you'll hear a chime signalling that the procedure 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 later reproduce the signal received from the vehicle key fob to open the car. To prevent this, manufacturers have added a security feature known as the CAN bus protocols to stop hackers from gaining access to the vehicle.
Certain manufacturers have a unique encryption on their keys that cannot be decoded using an ordinary program. These types of cars will need to be programmed by a professional. Therefore, you should only attempt this procedure with someone who has experience with electronics. Check the manual of your car or visit the manufacturer's website to learn how to program it. The steps to follow will differ depending on the type of vehicle.
Transponder chips
Car keys with transponder chips need special reconfiguration to work. While any hardware store can cut a new key for you, the biggest issue is how to integrate it in conjunction with your particular car. The key needs to be programmed to match the exact identification code on your car, otherwise it won't be able to start.
Transponder chips are a standard feature of modern automobiles and are designed to stop car theft. The chip is a microcircuit which transmits a radio frequency signal when the key is put into the ignition. The car then detects the signal and then starts the engine in case it matches the original frequency that was programmed into the vehicle. The car is also programmed so that it will stop when it detects an incorrect frequency. This makes it much harder for thieves who are not experienced to wire a vehicle and then start it.
A circuit board equipped with an induction coil connects the chip to the key. When the key is placed in the ignition, a magnetic field is created around the transponder. This generates a signal that is absorbed by the coil and sent to the key's identification. The key's ID number is then sent back to the vehicle, and if it matches the engine will start.
There are a variety of methods to program a key transponder, but each requires the use of a specific tool. You can purchase these tools online or from most locksmiths in the automotive industry. They are not cheap, but they're vital for programming the chip to your vehicle.
You could also make use of a transponder key that can be reprogrammed that was previously programmed for another vehicle. In this case, ensure that the key has not been damaged or that the transponder is not altered in any way. The chip can be read with a scanner, or a computer equipped with the USB connector.
Reprogramming a transponder key is quite simple, but it requires an expertly designed software and scan tool. It is recommended to contact an auto locksmith for assistance for those who are new to the process. Don't buy used keys since they may already be programmed and will not work with your car.
