Reprogramming Car Keys
Car keys with transponders are thought to keep vehicles more secure and less likely to be duplicated by thieves. However, keys may require reprogramming when it becomes damaged or lost.
You can change the programming of your key fobs at home, but you need to be aware of the correct procedure. For the best results you should have the following items:
Keys
The majority of modern vehicles require a transponder key in order to operate. This gives security and anti-theft protection. These keys must be programmed to your particular 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 purchase key fobs that can be replaced in online stores and numerous brick-and-mortar auto shops. But how do you know that the key fob you bought is genuine? Can you tell whether it was programmed for a different vehicle or if it could be programmed to work with your car?
To program a new car key you must first ensure that your vehicle is running. Insert the key that you'd like to program into the ignition, but don't turn it. You have just a few minutes before the system resets all commands and leaves the programming mode. For this reason, it is crucial to be quick and not wait between steps. Shut off the engine to avoid this. Switch the key from "on" to "off" to test the system. The door locks should cycle and you will hear a sound that indicates that the process was successful.
Some newer cars use a rolling key technology that stops thieves from using a stolen vehicle's key to open it. The technology is still susceptible to a method known as a replay attack, which allows thieves to record the signal received from the vehicle's key fob, then reproduce it to unlock the car. To stop this, manufacturers have added a security feature called the CAN bus protocol to prevent hacking attempts.
Certain manufacturers also employ special encryption on their key fobs which are not decoded by an ordinary program. These kinds of cars will need to be programmed by a professional, so you should only attempt this procedure with someone who has experience with electronics. It's a good idea to refer to your car's owner manual or look up the manufacturer on the internet, since the steps differ based on car model.
Transponder chips
Car keys that feature transponder chips require a special reprogramming to work. Any hardware store can offer you a new car key but the real challenge lies in implementing it to your vehicle. The key has to be programmed to match the exact identification number on your vehicle, or else it won't start.
Transponder chips, used to protect cars from theft are a standard feature of modern automobiles. The chip is a microcircuit that transmits a radio-frequency signal when the ignition key is placed. The car then scans for the signal and begins the engine if it is in line with the original frequency that was programmed into the vehicle. The car will also shut down if the frequency is invalid. This makes it more difficult for novice car thefts to connect a vehicle to a hot wire and then start it.
A circuit board that has an induction coil connects the key to the chip. When the key is placed in the ignition it creates a magnetic field generated around the transponder. This produces a signal which is absorbed by the coil, which sends it to the key's identification number. The key's ID number is then sent back to the vehicle, and if it matches the engine will start.
There are a few different ways to program a transponder keys, however, they all require an instrument that is specifically designed for the purpose. These tools are available online or from most automotive locksmiths. They are not cheap, but they are vital for programming the chip to your vehicle.
You may also use a reprogrammable key that was previously programmed for a different vehicle. In this case you'll need sure that the key is not damaged or the transponder been altered in any way. To do this, you'll need scanners or computers with a USB port to identify the chip and establish its identity.
The process of reprogramming the transponder key is simple, but it requires an expertly designed software and scan tool. It is best to consult an auto locksmith for assistance if you're a novice. Avoid buying used keys because they may already be programmed and will not work with your car.
EZ Installer
For decades, car owners who needed to replace their key fob had no other alternative than to visit a dealer to have their key paired to the vehicle. This is because in order to make modern keys work, they need to be "paired". This required expensive and complex equipment that was only available to dealers. The EZ Installer from Car Keys Express solves this issue for retailers and locksmiths by simplifying the process of connecting modern keys to vehicles.
The EZ Installer is a basic, "plug and play" OBD device that pairs new keys with vehicles without the need for complex equipment or programming tokens. It connects directly to the standard OBD port on the vehicle, and runs a mobile application that provides easy-to-follow instructions. The EZ Installer is compatible with all modern vehicles, including those that have proximity keys or push-button start. To see if programing key will work with a specific vehicle, look up the compatibility guide on Tom's website.

The EZ Installer also eliminates the need for costly monthly service agreements and updates, which means it could reduce costs for retailers while offering customers the same high-quality service as OEM equipment.
