Transponder keys are believed to be more secure for cars and harder to copy by thieves. However, a key may need to be reset when it becomes damaged or lost.
You can change the programming of your key fobs at home, however you should know the right process. To get the best results, you should have the following items:
Keys
Nearly all modern vehicles require a transponder key or fob in order to operate, providing security and anti-theft protection. These keys must be programmed to your particular vehicle and its features by a certified locksmith or dealer. It is expensive to replace them if they become lost, so it's best to have spares available. You can locate key fobs to replace them in online stores, as well as 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 another vehicle or if yours can be reprogrammed?
If you want to program an entirely new key, the first step is to ensure that your vehicle is running. Insert transponder key programmer wish to program into the ignition without turning it. You have only a few seconds left before the system resets all commands and exits the programming mode. This is why it is essential to move fast and not be able to wait between steps. To avoid this happening, turn off the engine. Turn the key from "on" to "off" to test the system. The door locks should cycle and you'll hear a sound that indicates that the process was successful.
Certain newer vehicles have rolling key technology, which prevents thieves from using a stolen vehicle's key to start it. The technology is still susceptible to a technique known as a replay attack which allows thieves to record the signal received from the key fob of the car and then replicate it to unlock the car. To stop this, manufacturers have introduced a security feature called the CAN bus protocol to prevent attacks on hacking.
Some manufacturers use a special encryption on their keys, which cannot be decoded by a simple program. You should only attempt this method if you have experience is in electronics. It is recommended to refer to the owner's manual of your vehicle or look up the manufacturer on the internet, since the steps differ based on vehicle model.
Transponder chips
Transponder chip car keys require special reprogramming in order to function. Any hardware store can give you a new car key, however the real challenge lies in making it work with your vehicle. A key that has been reprogrammed will need to match the specific identification number of the vehicle, or it won't start the engine.
Transponder chips, used to prevent car theft are a standard feature of modern cars. The chip is a tiny 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 the signal is in line with the original that was programmed in the vehicle. The car is also programmed so that it will shut down when it detects an incompatible frequency. This makes it harder for thieves with no experience to connect a vehicle to a hot wire and then start it.
The chip and the key are connected via a circuit board that includes an induction coil. When the key is placed in the ignition the magnetic field is created around the transponder. This creates a signal that is absorbed by the coil, which then transmits it to key's identification number. The key's ID number is sent back to the vehicle and if it matches the engine will begin to run.
There are a variety of methods to program a key transponder, however each requires an instrument that is specifically designed for. You can buy these tools on the internet or at many locksmiths in the automotive industry. These tools aren't expensive, but they are essential for programming the chip in your car.
You could also use a resettable key that was programmed for an alternative vehicle. In this scenario, ensure that the key isn't damaged or that the transponder has not been altered in any way. To accomplish this, you can use a scanner or a computer with a USB port to read the chip and determine its identity.
Reprogramming an transponder is a simple procedure, but it requires specific software. It also requires a scanner tool. If you're just beginning, it's best to seek help from an auto locksmith. Don't buy used keys since they could already be programmed and will not work with your car.
