Why We Do We Love Reprogramming Car Key (And You Should, Too!)
Reprogramming Car Keys
Transponder keys are believed to be more secure for vehicles and more difficult to copy by thieves. A key may have to be reprogrammed in event of damage or lost.
You can program key fobs yourself, but you must know the proper procedure. To get the best results, you'll need the following items:
Keys
The majority of modern vehicles require a transponder key to operate. This gives security and protection against theft. The keys must be programmed to your specific vehicle and its features by a certified dealer or locksmith. It's costly to replace them if they become lost, so it's a good idea to have spares available. You will also find replacement key fobs at various online stores and in many brick-and-mortar auto shops. But how do you know that the new one you purchased is authentic? Are you able to tell whether the unit is programmed to work with another vehicle or if it could be programmed differently?
If you are planning to program a new key first, you need to ensure that your vehicle is running. Insert the key you wish to program into the ignition, but do not turn it. You only have a few seconds before the car's system resets the commands and exits programming mode. It is important that you move quickly and do not wait between each step. Turn off the engine to stop this. 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 process has been successful.
Certain vehicles of recent years use rolling keys to stop thieves from using stolen keys to start the car. This feature is still susceptible to a technique known as replay attack. It allows thieves to record and later duplicate the signal generated by the key fob of the vehicle to unlock the car. To stop this, manufacturers have introduced a security feature called the CAN bus protocol to prevent attacks on hacking.
Certain manufacturers also have special encryption on their key fobs, that cannot be decoded with an ordinary program. You should only try this process if your experience is in electronic devices. Refer to the manual for your car or look up the manufacturer's website to learn how to program it. The steps will vary depending on the type 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 real issue is how to integrate it with your specific car. The key you reprogrammed needs to be compatible with the specific identification number of the vehicle or else it won't be able to start the engine.
Transponder chips are a standard feature of modern automobiles and are designed to stop car theft. The chip is a microcircuit that transmits a radio-frequency signal when the ignition key is placed. The car detects the signal and begins the engine only if the signal is in line with the one programmed into the vehicle. The vehicle is also programmed to shut down if it detects an invalid frequency. This makes it harder for thieves with no experience to hot-wire a vehicle and then start it.
The chip and the key are linked by a circuit board that includes an induction coil. When the key is placed in the ignition, a magnetic field is generated around the transponder. This produces a signal which is absorbed by the coil, which sends it to the key's identification number. The key's ID number is transmitted back to the vehicle and if it matches the engine will begin to run.
There are several ways to program a transponder keys, but they all involve using an instrument that is specifically designed for the purpose. These tools can be purchased through the internet or from many automotive locksmiths. These tools aren't expensive, but they are essential to program your car's chip.
You could also utilize a transponder that is reprogrammable that has been previously programmed for a different vehicle. In this instance, you'll need to make sure that the key has not been damaged or the transponder has been altered in any way. To do this, you'll need scanners or a computer equipped with an USB port to scan the chip and determine its identity.
The process of reprogramming an transponder's key is easy, but it will require an expertly designed software and scan tool. It's best to ask an auto locksmith for help in case you're not an expert. You should also avoid buying second-hand keys as they're probably already programmed and won't work with your car.
