Reprogramming Car Keys
Transponder keys are said to be more secure for vehicles and more difficult to copy by thieves. However, a key might need to be reprogrammed in the event that it is damaged or lost.
You can program key fobs yourself however, you must be aware of the proper procedure. You must have these things to ensure the most effective results:
Keys
Nearly all modern vehicles require some kind of transponder key or fob to operate, ensuring security and anti-theft protection. The keys have to be programmed to your specific vehicle and its features by a certified dealer or locksmith. It's expensive to replace them if they are lost, so it's better to have spares available. You can find key fobs to replace them in online stores and many brick and mortar auto shops. How can you be sure that the one you bought is genuine? Do you know whether the unit is programmed to work with another vehicle or if it could be reprogrammed?
To program a new car key you must first ensure that your car is running. Insert the key that you'd like to reprogramme into the ignition, but do not turn it. You only have a couple of seconds before the car's system reverts the commands and leaves programming mode. Therefore, it is important to move quickly and not be able to wait between steps. Turn off the engine to avoid this. You can check the car's system by turning the key to the "on" position and back to the "off" position. You should hear a chime signalling that the procedure was successful. The door locks will go through a cycle.
Certain vehicles of recent years use rolling keys to keep thieves from using stolen keys to open the vehicle. The technology is still susceptible to a technique known as a replay attack, which allows thieves to record the signal from the vehicle's key fob and then replicate it to open the car. To stop this, manufacturers added security features known as the CAN bus protocols to prevent hacking.
Some manufacturers also use special encryption on their key fobs, which are not decoded by an ordinary program. You should only try this method if your previous experience is with electronics. Check the manual of your car or look up the manufacturer's website to learn how to program it. The steps will vary according to the type of vehicle.
Transponder chips
Car keys with transponder chips require a specific reprogramming to function. While any hardware store can cut a new key for you, the main problem is to make it work in conjunction with your particular car. A key that has been reprogrammed will need to be matched with the exact identification number of your vehicle, or it won't start the engine.
Transponder chips, used to stop theft of cars, are a common feature of modern automobiles. The chip is a microcircuit that transmits a radio frequency signal when the key is inserted in the ignition. The car can detect the signal and starts the engine only if it matches the one programmed into the vehicle. The car is also programmed to shut down when it detects an incorrect frequency. This makes it more difficult for thieves with no experience to hot-wire a vehicle and then start it.
The key and the chip are connected via a circuit board that includes an induction coil. When the key is placed in the ignition, it creates an electromagnetic field around the transponder. This generates a signal that is absorbed by the coil, which transmits it to the key's identification number. The key's identification code is returned to the car and the engine will start when the identification number is in line with.
There are several ways to program a transponder key, however, they all require an appropriate tool. You can buy these tools on the internet or at many locksmiths for cars. These tools aren't expensive, but they are essential to program your car's chip.
You could also use a reprogrammable transponder key that has been previously programmed for another vehicle. In this instance you'll need to make sure that the key isn't damaged or the transponder has been altered in any way. To accomplish this, you'll need scanners or computers with a USB port to scan the chip and determine its identity.
Reprogramming an transponder is a simple process, but requires special software. It also requires the use of a scanner. It's best to ask an auto locksmith for help in case you're not an expert. Avoid buying used keys because they may already be programmed and will not work with your car.
