Reprogramming Car Keys
Transponder keys are said to be more secure for vehicles and more difficult to copy by thieves. However, keys may need to be reprogrammed if it becomes damaged or lost.
You can reprogram key fobs yourself, but you must know the correct process. You should have these items to achieve the best results:
Keys
Modern cars require a transponder key to operate. This is a security feature and anti-theft protection. The keys are programmed by a locksmith or an authorized dealer to function with your car's systems and specific model. They are expensive to replace in the event of loss and you should keep extras handy. You can also find replacement keys fobs on various websites and in many brick-and-mortar auto shops. How can you know that the one you purchased is genuine? Are you able to tell if the unit has been programmed to work with a different vehicle or if yours can be programmed differently?
If you're looking to program a new key the first step is to ensure that your vehicle is running. Insert the key you wish to reprogram into the ignition, but do not turn it. There are only a few seconds left before the system resets all commands and exits the programming mode. This is why it is crucial to be quick and not wait between steps. To avoid this happening, turn off the engine. You can check the system of your car by turning the key to the "on" position and back to the "off" position. You should hear a chime to indicate that the process was successful. The door locks will be able to cycle.
Certain newer vehicles utilize rolling key technology to prevent thieves from using stolen keys to start the car. This technology is still vulnerable to a technique known as a replay attack which allows thieves to record the signal from the key fob on the vehicle and reproduce it later to unlock the car. To counter this, manufacturers have introduced an additional security feature known as the CAN bus protocol to stop hacking attempts.
Some manufacturers also use special encryption on their key fobs that cannot be decoded with an easy program. These types of cars require programming by a professional, so you should only try this if you have experience working with electronics. It's a good idea to refer to the owner's manual for your car or look up the manufacturer on the internet, since these steps vary by car model.
Transponder chips
Car keys with transponder chips require a special reprogramming to work. While any hardware store can cut keys for you, the real challenge is making it function with your specific car. A reprogrammed key will need to be matched with the exact identification number of your car otherwise it won't even 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 key is inserted in the ignition. The car then detects the signal and begins the engine in case it matches the original frequency that was programmed into the vehicle. The car will also shut down if the frequency is invalid. This makes it much harder for novice car thieves to connect a vehicle with hot wires and start it.
The key and the chip are linked by the circuit board which includes an induction coil. When the key is inserted into the ignition, it creates a magnetic field around the transponder. This creates a signal which is received by the coil and then transmitted to the key's identification. The key's identification number is returned to the car and the engine is started when the identification number is in line with.
There are a few different ways to program a transponder keys, however, they all require an appropriate tool. You can purchase these tools on the internet or at many locksmiths in the automotive industry. They're not cheap, but they're crucial for programming the chip to your vehicle.
You could also use a reprogrammable transponder key that was previously programmed for a different vehicle. In this instance, you must make sure that the key has not been damaged or that the transponder has not been altered in any way. The chip can be read using a scanner, or a computer that has a USB connector.
Reprogramming the transponder key is easy, but it will require specialized software and a scan tool. If you're just beginning it is recommended to seek the assistance of an auto locksmith. Avoid buying used keys because they could already be programmed and won't work with your car.
EZ Installer

To determine if it'll work for a particular vehicle, check the compatibility guide on Tom's website.
If the device fails to program a remote or key purchased from Tom's into a compatible vehicle, a full refund is offered.
