Reprogramming Car Keys
Transponder keys for car keys are thought to keep cars more secure and are harder for thieves to duplicate. However, keys may require reprogramming in the event that it is damaged or lost.
You can change the key fobs you own but you must be aware of the correct process. For the best results you must have the following items:
Keys
Most modern cars require a transponder key to operate. This provides security and anti-theft protection. These keys are programmed by a locksmith or an authorized dealer to function with the car's systems and the specific model. They can be costly to replace in the event of loss, so it is recommended to keep spare keys in the car. You can also find replacement key fobs on various websites and in many brick-and-mortar auto shops. But how can you tell that the new one you have bought is genuine? Are you able to tell whether the unit has been programmed to work with a different vehicle or if yours can be programmed differently?
If you want to program an entirely new key first, you need to ensure that your vehicle is operating. Insert the key you want to program into the ignition, but do not turn it. You only have just a few seconds before the car's system reverts the commands and leaves programming mode. For this reason, it is important to move fast and not wait between steps. To prevent this from happening, shut off the engine. You can check the car's system by turning the key to the "on" position and then back to the "off" position. The door locks should be able to cycle, and you'll hear a chime signalling that the procedure was successful.
Certain newer vehicles utilize rolling keys to stop thieves from using stolen keys to open the vehicle. The technology is still susceptible to a technique dubbed replay attacks which allows thieves to record the signal from the vehicle's key fob, then reproduce it to unlock the car. To counter this, manufacturers have added an additional security feature known as the CAN bus protocol to thwart hacking attempts.
Certain manufacturers also employ special encryption on their key fobs, that cannot be decoded with an easy program. It is best to only attempt this method if your previous experience is in electronics. Refer to the manual for 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 special reprogramming to function. While any hardware store can cut keys for you, the biggest issue is how to integrate it with your specific car. A key that has been reprogrammed will need to be matched with the exact identification number of the vehicle or else it won't be able to start the engine.
Transponder chips are a typical feature of modern cars and are designed to stop car theft. The chip is a microcircuit that emits a radio frequency signal when the key is placed in the ignition. The car detects the signal and starts the engine only if the signal is in line with the one programmed into the vehicle. The car also shuts down if a frequency is invalid. This makes it difficult for thieves with no experience to wire a vehicle hot and then turn it on.
A circuit board equipped with an induction coil that 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 sends it to the key's identification number. The key's identification code is transmitted back to the car, and the engine starts when the identification number matches.
There are many methods to program a transponder keys, but they all involve using an appropriate tool. These tools can be purchased on the internet or at most auto locksmiths. They are not cheap, but they are vital for programming the chip into your car.
You could also utilize a transponder that is reprogrammable that has been previously programmed for a different vehicle. In this scenario, make sure that the key hasn't been damaged or the transponder isn't altered in any way. The chip can be read with a scanner, or a computer with a USB connector.
The process of reprogramming a transponder key is quite simple, however it requires specialized software and a scan tool. It is recommended to contact an auto locksmith for assistance for those who are new to the process. It is also recommended to avoid purchasing second-hand keys as they are likely already programmed and will not work with your car.
