Reprogramming Car Keys
Transponder keys are thought to be more secure for vehicles and more difficult to copy by thieves. However, a key may need to be reprogrammed when it becomes damaged or lost.
You can change the programming of your key fobs at home, however you need to be aware of the proper procedure. For the best results you must have the following items:
Keys
Nearly all modern vehicles require some kind of transponder key or fob to work, which provides security and anti-theft protection. The keys have to be programmed to the specific vehicle and its systems by an authorized locksmith or dealer. It's costly to replace them if they're lost, so it's best to keep extras on hand. You can locate 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 one you purchased is genuine? Can you tell whether 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 verify that your car is running. Insert the key that you want to reprogramme into the ignition, but don't turn it. There are only a few seconds before the system will reset all commands and exits the programming mode. It is crucial to be quick and don't be patient between each step. To avoid this happening, turn off the engine. You can test the car's security system by turning the key to the "on" position, then back to the "off" position. There should be a chime to indicate that the process was successful. The door locks will go through a cycle.
Certain vehicles of recent years use rolling keys to keep thieves from using stolen keys to start the vehicle. This feature is still susceptible to a technique called replay attack. It allows thieves to record and then reproduce the signal from the key fob of the vehicle to unlock the car. To prevent this, manufacturers have added a security feature called CAN bus protocol to thwart attacks on hacking.
Some manufacturers also use special encryption on their key fobs which are not decoded by a simple program. These kinds of cars will need to be programmed by a professional, and you should only attempt this procedure with someone who has experience with electronic devices. Check the manual of your car or look up the website of the manufacturer to find out how to program it. The steps will vary depending on the type of vehicle.
Transponder chips
Car keys with transponder chips require special reconfiguration to work. Any hardware store can offer you a new car key, but the real challenge lies in making it work with your car. The key you reprogrammed needs to be matched with the exact identification number of the vehicle 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 microcircuit which transmits a radio frequency signals when the key is put in the ignition. The car can detect the signal, and starts the engine only if the signal matches the original that was programmed into the vehicle. The car will also shut down if the frequency is invalid. This makes it much more difficult for novice car thieves to wire a vehicle and start it.
The chip and the key are connected via the circuit board which includes an induction coil. When the key is placed in the ignition it creates a magnetic field generated around the transponder. This generates a signal that is absorbed by the coil and sent to the key identification number. The key's ID number is transmitted back to the vehicle and if it matches the engine will start.
There are several methods to program a key transponder, however all of them require a special tool. These tools can be bought on the internet or at most auto locksmiths. They are not cheap, but they are vital for programming the chip in your vehicle.
You may also utilize a transponder that is reprogrammable that has been previously programmed for another vehicle. In this case you'll need to make sure that the key has not been damaged or the transponder been altered in any way. To accomplish this, you'll need a scanner or a computer equipped with a USB port to scan the chip and determine its identity.
Reprogramming an transponder is a simple procedure, but it requires specialized software. It also requires a scanner tool. It's best to ask an auto locksmith for assistance in case you're not an expert. Avoid buying used keys as they may already be programmed, and they won't work with your car.

For a long time, owners of cars who required a replacement for their key fob had no choice than to visit an auto dealer to get their key connected to the vehicle.

The EZ Installer works with most modern vehicles with proximity keys or push-button start. Visit the compatibility guide on Tom's site to see if your vehicle is compatible.
If the device is unable to program the remote or key purchased from Tom's into a compatible vehicle the full refund will be available.
