Reprogramming Car Keys
Transponder keys are said to be more secure for cars and harder to copy by thieves. However, a key may need to be reset in the event that it is damaged or lost.
You can reprogram your key fobs at home, but you need to be aware of the proper procedure. For the best results you should have the following items:
Keys
Modern cars require a transponder key to operate. This is a security feature and protection against theft. These keys must be programmed to your specific car and its systems by a licensed dealer or locksmith. It is expensive to replace them if they're lost, so it's better to have spares in your possession. You will also find replacement key fobs on various websites and in many brick-and-mortar auto shops. But how do you know that the one you have bought is genuine? Can you tell whether it was programmed to work with another vehicle or if it is able to be programmed to work with your car?
To program a new car key you must first verify that your car is running. Insert the key that you wish to program into the ignition, but do not turn it. You will only have just a few seconds before the car's system reverts the commands and exits programming mode. Therefore, it is important to move quickly and not wait between steps. To prevent this from happening, shut off the engine. You can test the car's system by turning the key to the "on" position and back to the "off" position. The door locks should cycle, and you'll hear a chime signalling that the process was successful.
Some newer cars use a rolling key technology that stops thieves from using stolen cars' key to open it. This feature is still vulnerable to a technique dubbed replay attack that allows thieves to record the signal from the key fob of the car, then reproduce it to unlock the car. To counter this, manufacturers have added a security feature called the CAN bus protocol to stop hacking attempts.

Certain manufacturers also employ special encryption on their key fobs which cannot be decoded by a simple program. These types of vehicles will need to be programmed by a professional, and you should only attempt this procedure if you have experience working with electronic devices. Refer to the manual for your car or go to the manufacturer's website to find out how to program it. The steps are different according to the type of vehicle.
Transponder chips
Transponder chip car keys require special reprogramming in order to work. While any hardware store can cut a new key for you, the biggest issue is how to integrate it in conjunction with your particular car. The key you reprogrammed needs to be compatible with the specific identification number of your vehicle or else it won't be able to start the engine.
Transponder chips are a standard feature of modern cars and are designed to guard against car theft. The chip is a tiny microcircuit that transmits a radio-frequency signal when the ignition key is inserted. The car detects the signal and begins the engine only if the signal matches the original that was programmed into the vehicle. The car also shuts down if a frequency is invalid. This makes it much more difficult for novice car thieves to hot wire a vehicle and then start it.
A circuit board with an induction coil that connects the chip to the key. When the key is inserted into the ignition, it creates an electric field around the transponder. This generates a signal that is taken up by the coil and then transmitted to the key's identification. The key's identification code is sent back to the car and the engine is started when the identification number is in line with.
There are a few different methods to program a transponder keys, however, they all require an appropriate tool. You can buy these tools online or from most automotive locksmiths. These tools aren't inexpensive, but they are vital to program your car's chip.
You could also make use of a transponder key that can be reprogrammed that was previously programmed for another vehicle. In this scenario, make sure that the key has not been damaged or the transponder isn't altered in any way. To do this, you'll need scanners or a computer equipped with an USB port to read the chip and determine its identity.
Reprogramming an transponder is a simple procedure, but requires specialized software. It also requires an scanner tool. If you're new to the process it is recommended to seek help from an auto locksmith. Don't buy used keys since they could already be programmed and will not work with your vehicle.
EZ Installer
For a long time, owners of cars who required replacement of their key fob had no other choice than to visit a dealership to have their key linked to their vehicle.
