Reprogramming Car Keys

Transponder keys are believed to be more secure for vehicles and more difficult to copy by thieves. However, a key may require reprogramming when it becomes damaged or lost.

You can program key fobs yourself, but you must know the proper procedure. To get the best results, you must have the following items:

Keys

Most modern vehicles require a transponder fob or transponder keys to work, which provides security and protection against theft. These keys are programmed by a locksmith or authorized dealer to work with your car's systems and the specific model. They are costly to replace if lost therefore, you should keep extras handy. You can purchase replacement key fobs in online stores as well as many brick and mortar auto shops. How can you be sure that the key you purchased is authentic? Do you know whether the unit has been programmed to work with a different vehicle, or if it can be programmed again?

To program a new car key cut and programed key, you must first verify that your vehicle is operating. Insert the key you want to reprogram into the ignition, but do not turn it. You have just a few minutes before the system will reset all commands and then exits the programming mode. For this reason, it is crucial to move fast and not wait between steps. Turn off the engine to prevent this. 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 cycle, and you will hear a chime signalling that the process has been successful.

Some newer cars use a rolling key technology, which keeps thieves from using stolen cars' key to open it. This feature is still susceptible to a technique dubbed replay attack. It allows thieves to record and reproduce the signal received from the key fob of the vehicle to unlock the car. To counter this, manufacturers have introduced a security feature called CAN bus protocol to stop hacking attempts.

Some manufacturers use a special encryption on their keys that cannot be decoded by an easy program. These types of vehicles require to be programmed by a professional. Therefore, you should only attempt this procedure only if you've worked with electronic devices. It is a good idea to consult the owner's manual for your car or look up the manufacturer on the internet, since the steps will differ depending on the vehicle type.

Transponder chips

Car keys that feature transponder chips require special reprogramming to work. While any hardware store can cut a new key for you, the biggest challenge is making it function with your specific car keys reprogramming. A key that has been reprogrammed will need to be matched with the exact identification number of the vehicle, or it won't start the engine.

Transponder chips, used to prevent car theft are a standard feature of modern automobiles. The chip is a microcircuit that transmits a radio-frequency signal when the ignition key is placed. The car detects the signal and starts the engine only if the signal is in line with the original that was programmed in the vehicle. The car is also programmed to shut down when it detects an incompatible frequency. This makes it more difficult for novice car thieves to hot wire a vehicle and then start it.

The key and the chip are connected via the circuit board which includes an induction coil. When the key is placed in the ignition, it creates a magnetic field around the transponder. This generates a signal, which is absorbed by the coil and then transmitted to the key's identification. The key's identification number is then transmitted back to the car, and the engine starts when the identification number matches.

There are many methods to program a transponder key programming key, however, all require a special tool. You can purchase these tools on the internet or at many locksmiths in the automotive industry. These tools are not expensive, but they are essential for programming your car's chip.

You could also use a reprogrammable key that was previously programmed for another vehicle. In this scenario you'll need to make sure that the key isn't damaged or the transponder has been altered in any way. To accomplish this, you can use scanners or a computer equipped with a USB port to scan the chip and determine its identity.

Reprogramming the transponder is a straightforward procedure, but requires specialized software. It also requires a scanner tool. It's best to ask an auto locksmith for assistance for those who are new to the process. Don't buy used keys since they may already be programmed and will not be compatible with your vehicle.

EZ Installer

For a long time, owners of cars who needed to replace their key fob had no other choice than to visit a dealer to have their key electronically paired to the vehicle. This is because in order to make modern keys function they have to be "paired". This required expensive and complicated equipment that was only available to dealers. The EZ Installer by Car Keys Express simplifies the process of pairing modern keys with vehicles used by locksmiths and retailers.

The EZ Installer is compatible with most newer models that include proximity keys or push button start. To determine if it'll work for a particular vehicle, refer to the compatibility guidelines on Tom's site.
