Reprogramming Car Keys

Transponder keys are thought to be more secure for cars and harder to copy by thieves. However, keys may need to be reprogrammed in the event that it is damaged or lost.

You can reprogram your key fobs at home, however you must know the right process. For the best results, you must have the following items:

Keys

Almost all modern cars require some kind of transponder fob or transponder keys to operate, providing security and anti-theft protection. The keys must be programmed to your particular vehicle and its systems by a certified locksmith or dealer. They are costly to replace if they are lost, so you should keep extras handy. You can locate replacement key fobs in online stores, as well as many brick-and mortar auto shops. How can you ensure that the key you purchased is genuine? Are you able to tell whether it was programmed for another car or if it could be reprogrammed for yours?

If you are planning to program a new key first, you need to ensure that your car is running. Insert the key that you wish to reprogramme into the ignition, but do not turn it. You only have a couple of seconds before the car's system resets the commands and leaves programming mode. For this reason, it is important to move quickly and not pause between steps. Shut off the engine to avoid this. You can check the car's security system by turning the key to the "on" position, then back to the "off" position. The door locks should cycle and you will hear a sound that indicates that the process has been successful.

Certain newer vehicles have rolling key technology, which prevents thieves from using stolen cars' key to start it. This technology is still vulnerable to a technique dubbed a replay attack which allows thieves to record the signal received from the vehicle's key fob, then reproduce it to open the car. To prevent this, manufacturers added security features known as the CAN bus protocols to ward off hacking.

Certain manufacturers also employ special encryption on their key fobs, which cannot be decoded by an ordinary program. These types of cars will need to be programmed by a professional, so you should only attempt this process only if you've worked with electronics. Check the manual of your car or visit the manufacturer's website to find out how to program it. The steps to follow will differ depending on the model of vehicle.

Transponder chips

Car keys with transponder chips require a special reprogramming to work. While any hardware store can cut a new key for you, the real problem is to make it work in conjunction with your particular car. A reprogrammed key will need to be compatible with the exact identification number of your car otherwise it won't even start the engine.

Transponder chips are a common feature of modern cars and are designed to prevent car theft. The chip is a small microcircuit that transmits a radio-frequency signal when the ignition key is put in.

The car is also programmed to stop when it detects an incompatible frequency. This makes it much harder for car thieves with no experience to wire a vehicle and start it.

A circuit board that has an induction coil connects the key to the chip. When the key is put in the ignition, a magnetic field is generated around the transponder. This produces a signal which is amplified by the coil which sends it to the key's identification number. The key's identification number is then sent back to the car, and the engine starts when the identification number is in line with.

There are several ways to program a transponder key however, they all require a special tool. These tools are available on the internet or at most auto locksmiths. They are not cheap, but they are essential for programming the chip into your vehicle.

In this instance, you must ensure that the key has not been damaged or the transponder is not altered in any way. To check this, you'll need a scanner 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 simple, but it requires an expertly designed software and scan tool. It is best to consult an auto locksmith for assistance if you're a novice. Also, avoid buying second-hand keys as they're likely to be programmed and won't work with your car.

EZ Installer
