Transponder keys are believed to be more secure for cars and are more difficult to copy by thieves. The key could need to be reprogrammed in event that it is damaged or lost.
You can reprogram your key fobs at home, however you should know the right process. To get the best results, you should have the following items:
Keys
Most modern vehicles require some kind of transponder fob or transponder keys to operate, ensuring security and protection against theft. The keys must be programmed to your specific vehicle and its features by an authorized locksmith or dealer. They are expensive to replace if lost, so you should keep extras handy. You can also find replacement key fobs on various websites and in a variety of brick-and-mortar automotive shops. How can you know that the one you purchased is genuine? Are you able to tell whether it has been programmed for another car or if it can be programmed to work with your car?
If you're looking to program an entirely new key the first step is to ensure that your car is operating. Insert the key you wish to reprogram into the ignition without turning it. You have only a few seconds before the system will reset all commands and leaves the programming mode. It is essential to move quickly and do not wait between each step. Turn off the engine to stop this. You can check the car's system by turning the key to the "on" position, then back to the "off" position. You should hear a sound indicating that the process was successful. The door locks will go through a cycle.
Certain newer vehicles have rolling key technology that keeps thieves from using a stolen car's key to open it. The feature is still vulnerable to a technique called replay attack. It allows thieves to record and later reproduce the signal from the car key fob to open the car. To combat this, manufacturers have added the security feature known as the CAN bus protocols to ward off hackers from gaining access to the vehicle.
Some manufacturers use a special encryption on their keys that can't be decoded with an ordinary program. These types of cars will need to be programmed by a professional. Therefore, you should only attempt this process if you have experience working with electronic devices. Check car keys reprogramming of your car or go to the manufacturer's website for information on how to program it. The steps will vary according to the type of vehicle.
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 to work with the specific car you own. The key needs to be programmed to match the exact identification number of your car, otherwise it won't start.
Transponder chips are a common feature in modern cars and are designed to prevent car theft. The chip is a microcircuit which emits a radio frequency signal when the key is inserted in the ignition. The car then detects the signal and starts the engine if it matches the original signal that was programmed into the vehicle. The car will also shut down if the frequency is not valid. This makes it much harder for novice car thieves to connect a vehicle with hot wires and then start it.
A circuit board that has an induction coil that connects the key to the chip. When the key is placed in the ignition it creates a magnetic field around the transponder. This generates a signal, which is taken up by the coil and then transmitted to the key identification number. The ID number of the key is sent back to the vehicle, and if it is in line with the engine will start.
There are several ways to program a transponder key but they all involve using a special tool. You can purchase these tools online or at most locksmiths in the automotive industry. These tools aren't inexpensive, but they are vital for programming the chip in your car.
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 the transponder has been altered in any way. To check this, you can use scanners or computers with an USB port to read the chip and determine its identity.
Reprogramming a transponder key is quite simple, however it requires special software and a scanning tool. It is best to consult an auto locksmith for help in case you're not an expert. It is also recommended to avoid purchasing second-hand keys, since they're probably already programmed and will not be compatible with your car.
