Reprogramming Car Keys
Transponder keys for car keys are thought to keep cars more secure and are more difficult for thieves to duplicate. However, a key might require reprogramming when it becomes damaged or lost.
You can program key fobs yourself, but you must know the correct procedure. It is essential to have these items to ensure the best results:
Keys
The majority of modern vehicles require a transponder keys to operate. This gives security and anti-theft protection. The keys must be programmed to the specific vehicle and its systems by a licensed locksmith or dealer. They can be costly to replace in the event of loss therefore, you should keep extras handy. You can locate key fobs to replace them in online stores and many brick-and mortar auto shops. How can you be sure that the one you purchased is genuine? Are you able to tell whether the unit has been programmed to work with another vehicle or if it could be programmed differently?
If you're looking to program a new key the first step is to ensure that your car is on and running. Insert the key that you wish to program into the ignition, but do not turn it. You will only have a few seconds before the car's system resets commands and then exits programming mode. It is crucial to 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. There should be a chime to indicate that the process was successful. The door locks will be able to cycle.
Certain newer vehicles have rolling key system, which stops thieves from using a stolen vehicle's key to open it. This feature is still susceptible to a technique called a replay attack. It allows thieves to record and then reproduce the signal received from the key fob of the vehicle to unlock the car. To prevent this, manufacturers have introduced a security feature called the CAN bus protocol to stop attacks on hacking.
Certain manufacturers also employ special encryption on their key fobs which cannot be decoded by a simple program. You should only try this process if your experience is with electronics. Consult your car's manual or go to the manufacturer's website to learn how to program it. The steps to follow will differ according to 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 challenge is making it function to work with the specific car you own. The key you reprogrammed needs to match the exact identification number of your vehicle otherwise it won't even start the engine.
Transponder chips are a common feature in modern cars and are designed to stop car theft. The chip is a small microcircuit that transmits a radio-frequency signal when the ignition key is put in. The car then scans for the signal and begins the engine in case it matches the original one that was programmed into the vehicle. The vehicle is also programmed to shut down when it detects an incorrect frequency. This makes it more difficult for thieves who are not experienced to connect a vehicle with hot wires and then start it.
A circuit board with an induction coil connects the chip to the key. When the key is put in the ignition it creates a magnetic field generated around the transponder. This produces a signal which gets amplified by the coil which then transmits it to key's identification number. The key's identification number is returned to the car and the engine is started when the identification number is in line with.
There are many ways to program a transponder, however all of them require an instrument that is specifically designed for. You can buy these tools online or at most automotive locksmiths. These tools aren't inexpensive, but they are vital for programming your car's chip.
You may also make use of a transponder key that can be reprogrammed that has been previously programmed for another vehicle. In this instance you'll need sure that the key is not damaged or the transponder been altered in any way. To accomplish this, you'll need scanners or computers with a USB port to identify the chip and establish its identity.
Reprogramming a transponder is a simple procedure, but requires specific software. It also requires the use of a scanner. If you're a beginner you should seek the assistance of an auto locksmith. You should also avoid buying second-hand keys as they're probably already programmed and won't be compatible with your car.
