Reprogramming Car Keys
Transponder keys are said to be more secure for vehicles and more difficult to copy by thieves. However, keys may need to be reset if it becomes damaged or lost.
You can reprogram key fobs yourself but you must be aware of the correct process. It is essential to have these items to ensure the best results:
Keys
Most modern cars require a transponder key in order to operate. This gives security and anti-theft protection. The keys are programmed by a locksmith or an authorized dealer to function with your car's systems and the specific model. It's costly to replace them if they are lost, so it's a good idea to keep extras on hand. You can purchase key fobs that can be replaced in online stores as well as many brick-and mortar auto shops. How can you be sure that the key you purchased is genuine? Do you know if the unit has been programmed to work with a different vehicle or if it could be programmed again?
To program a new car key you must first ensure that your vehicle is running. Insert the key that you'd like to reprogramme into the ignition, but do not turn it. There are just a few minutes before the system will reset all commands and leaves the programming mode. It is important that you be quick and don't delay between each step. To avoid this happening, shut off the engine. 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 sound to indicate that the process was successful. The door locks will be able to cycle.
Some newer cars use a rolling key technology, which prevents thieves from using a stolen car's key to open it. This 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 counter this, manufacturers have added a security feature called CAN bus protocol to stop hacking attempts.
Certain manufacturers have a unique encryption on their keys that can't be decoded with an easy program. You should only try this method if you have experience is in electronics. Check the manual of your car or visit the manufacturer's website to find out how to program it. The steps are different depending on the model of vehicle.
Transponder chips
Car keys with transponder chips require a special reprogramming to function. Any hardware store can offer you an entirely new car key, but the real challenge lies in implementing it to your vehicle. The key must be programmed to match the exact identification number of your vehicle, or else it will not start.
Transponder chips, used to prevent car theft are a standard feature of modern cars. The chip is a small microcircuit which transmits a radio-frequency signal when the ignition key is placed. The car detects the signal and starts the engine only if it matches the original one that was programmed in the vehicle. The car also shuts down if the frequency is invalid. This makes it more difficult for thieves who aren't experienced to hot-wire a vehicle and then start it.
The key and the chip are connected by a circuit board that includes an induction coil. When the key is put in the ignition it creates a magnetic field created around the transponder. This produces a signal which is amplified by the coil which transmits it to the key's identification number. The key's identification number is returned to the car and the engine will start when the identification number is in line with.
There are many methods to program a transponder key, however, all require an instrument that is specifically designed for the purpose. You can buy these tools on the internet or at many locksmiths in the automotive industry. They are not cheap, but they are essential for programming the chip to your car.
You may also use a reprogrammable transponder key that was previously programmed for a different vehicle. In this scenario you'll need sure that the key isn't damaged or that the transponder has been altered in any way. The chip can be read using a scanner, or a computer that has an USB connector.
Reprogramming the transponder is a straightforward process, but requires specialized software. It also requires a scanner tool. If you're a beginner it is recommended to seek help from an auto locksmith. Also, avoid buying second-hand keys, since they are likely already programmed and won't work with your car.
