Reprogramming Car Keys
Transponders in car keys are believed to make cars more secure and are less likely to be duplicated by thieves. However, a key might need to be reprogrammed if it becomes damaged or lost.
You can reprogram your key fobs at home, but you must be aware of the proper procedure. For the best results, you'll need the following items:
Keys
Nearly all modern vehicles require some kind of transponder key or fob to operate, ensuring security and protection against theft. These keys are programmed by a locksmith or an authorized dealer to function with your car's system and specific model. It is expensive to replace them if they become lost, so it's a good idea to have spares in your possession. You can also find replacement keys fobs at various online stores and in many brick-and mortar auto shops. How can you be sure that the one you bought is genuine? Can you tell whether it has been programmed for a different vehicle or if it could be reprogrammed to fit your vehicle?
If you want to program a new key, the first step is to ensure that your car is on and running. Insert the key you want to reprogramme into the ignition, but don't turn it. You have only a few seconds left before the system will reset all commands and exits the programming mode. Therefore, it is important to move fast and not wait between steps. Shut off the engine to avoid this. Change the key from "on" to "off" to test the system. You should hear a sound signalling that the procedure was successful. The door locks will cycle.
Some newer vehicles use rolling keys to keep thieves from using stolen keys to start the vehicle. This feature is still vulnerable to a method known as a replay attack that allows thieves to record the signal received from the vehicle's key fob, then reproduce it to open the car. To stop this, manufacturers added security features known as the CAN bus protocols to prevent hacking.
Certain manufacturers also have special encryption on their key fobs that cannot be decoded with an easy program. You should only try this process if your experiences are with electronic devices. It is a good idea to read your car's owner manual or search for the manufacturer on the internet, since the steps will differ depending on the vehicle type.
Transponder chips
Car keys that feature transponder chips require a special programming to function. Any hardware store can make you an entirely new car key, but the real challenge lies in implementing it to your car. The key you reprogrammed needs to be matched with the specific identification number of the vehicle, or it won't start the engine.
Transponder chips are a standard feature of modern automobiles and are designed to guard against car theft. The chip is a microcircuit that emits a radio frequency signal when the ignition key is inserted. The car then scans for the signal and then starts the engine if it is in line with the original signal that was programmed into the vehicle. The car will also shut down if a frequency is invalid. This makes it more difficult for thieves with no experience to connect a vehicle to a hot wire and then turn it on.
A circuit board that has an induction coil that connects the chip to the key. When the key is inserted into the ignition it creates a magnetic field around the transponder. This creates a signal which is absorbed by the coil and then transmitted to the key's identification. The ID number of the key is sent back to the vehicle, and if it matches the engine will start.
There are many methods to program a key transponder, but each requires a special tool. You can buy these tools online or at most locksmiths for cars. They're not cheap, but they're vital for programming the chip to your car.
You could also use a reprogrammable key that was previously programmed for an alternative vehicle. In this scenario you'll need to make sure that the key is not damaged or the transponder has been altered in any way. The chip can be read with a scanner, or a computer equipped with the USB connector.
The process of reprogramming the transponder key is easy, but it will require special software and a scanning tool. If you're a beginner you should seek out the help of an auto locksmith. Also, avoid buying second-hand keys as they are likely already programmed and will not work with your vehicle.
EZ Installer
For a long time, owners of cars who required a replacement for their key fob had no other alternative than to visit an auto dealer to have their key connected to the vehicle. This is because modern keys need to be "paired" to a specific vehicle to function, which required the use of expensive and complicated equipment that only dealers could access. The EZ Installer by Car Keys Express simplifies the process of pairing up modern keys to vehicles for locksmiths and retailers.

Check the compatibility guide at Tom's site to see if your vehicle is compatible.
If the device fails to program a remote or a key purchased from Tom's into a vehicle that is compatible the full refund will be available.
Contrary to conventional programming equipment which costs retailers and key professionals tens of thousands of dollars in "token" fees per key, the EZ Installer Pro does not charge these costs. It is able to be used for as long as the key professional or retailer requires. The EZ Installer eliminates the need for costly monthly service contracts and software updates.
