Reprogramming Car Keys
Transponders in car keys are thought to keep vehicles more secure and less likely to be duplicated by thieves. Keys may need to be reprogrammed in event of damage or lost.
You can program key fobs yourself but you must be aware of the correct process. For the best results you must have the following items:
Keys
The majority of modern vehicles require a transponder key in order to operate. This gives security and protection against theft. The keys are programmed by a locksmith or an authorized dealer to function with your car's systems and the specific model. It's costly to replace them if they're lost, so it's best to have spares available. You can also find replacement key fobs on various websites and in many brick-and-mortar auto shops. But how do you know that the new one you have bought is authentic? Are you able to tell whether the unit is programmed to work with another vehicle or if it could be reprogrammed?
If you're looking to program an entirely new key, the first step is to make sure that your car is on and running. Insert the key you wish to program into the ignition, but do not turn it. You have only a few seconds left before the system will reset all commands and leaves the programming mode. For this reason, it is important to move quickly and not be able to wait between steps. Turn off the engine to prevent this. Turn the key from "on" to "off" to test the system. 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 stops thieves from using stolen cars' key to start it. The technology is still susceptible to a technique dubbed replay attacks, which allows thieves to record the signal of the key fob of the car, then reproduce it to open the car. To prevent this, manufacturers have added a security feature known as the CAN bus protocols to stop hackers from gaining access to the vehicle.
Certain manufacturers employ a specific encryption on their keys, which can't be decoded with an ordinary program. These types of cars require programming by a professional, so you should only attempt this process if you have experience working with electronics. Consult your car's manual or look up the website of the manufacturer to find out how to program it. The steps to follow will differ depending on the model of vehicle.
Transponder chips
Car keys that feature transponder chips require special reconfiguration to work. Any hardware store can offer you a new car key, but the real challenge is in implementing it to your vehicle. A reprogrammed key will need to match the exact identification number of your car otherwise it won't even start the engine.
Transponder chips, which are used to protect cars from theft are a standard feature of modern cars. The chip is a small microcircuit that emits a radio frequency signal when the ignition key is put in. The car then recognizes the signal and then starts the engine if it matches the original frequency that was programmed into the vehicle. The vehicle is also programmed to stop when it detects an incorrect frequency. This makes it much more difficult for car thieves with no experience to wire a vehicle and then start it.
The chip and the key are linked by the circuit board which includes an induction coil. When the key is inserted into the ignition it creates an electromagnetic field around the transponder. key programer creates a signal that gets amplified by the coil which sends it to the key's identification number. 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, but they all involve using an appropriate tool. You can buy these tools online or at most automotive locksmiths. They are not cheap, but they're essential for programming the chip in your car.
You can also use an reprogrammable key that was previously programmed for a different vehicle. In this case you'll need to make sure that the key is not damaged or the transponder been altered in any way. To do this, you'll need scanners or computers equipped with an USB port to read the chip and determine its identity.
Reprogramming an transponder is a simple procedure, but requires special software. It also requires a scanner tool. If you're a beginner you should seek help from an auto locksmith. It is also recommended to avoid purchasing secondhand keys, as they're probably already programmed and will not be compatible with your car.
EZ Installer
In the past those who wanted to replace their key fob had to visit an authorized dealer to get it digitally paired to the vehicle.

To determine if it'll work with a specific vehicle, refer to the compatibility guide on Tom's website.
A full-money-back guarantee is provided in the event that the device cannot successfully program a remote or key purchased from Tom's for a vehicle that is compatible.
Unlike traditional programming equipment, which costs retailers and key professionals hundreds of thousands of dollars in "token" fees per key, the EZ Installer Pro does not charge these costs. It is available as long as a key professional or retailer wants. The EZ Installer also eliminates the requirement for expensive monthly service contracts and updates, so it will save retailers money while providing customers with the same high-quality service as OEM equipment. It also comes with a world-class warranty that covers all hardware and software for life.
