Reprogramming Car Keys
Car keys with transponders are believed to make vehicles more secure and less likely to be duplicated by thieves. A key may have to be programmed again in the event that it is damaged or lost.
You can reprogram key fobs yourself, but you must know the correct process. You must have these things to get the most effective results:
Keys
The majority of modern vehicles require a transponder key in order to operate. This gives security and anti-theft protection. The keys are programmed by a locksmith or an authorized dealer to function with the car's systems and the specific model. They are costly to replace in the event of loss and you should have spares in your car. You will also find replacement key fobs at various online stores and in many brick-and mortar auto shops. But how do you know that the new one you purchased is genuine? Are you able to tell whether the unit has been programmed to work with another vehicle, or if it can be programmed differently?
To program a new car keys, first make sure that your vehicle is running. Insert the key you'd like to program into the ignition, but don't turn it. There are only a couple of seconds before the car's system resets the commands and then exits programming mode. This is why it is important to move quickly and not wait between steps. To avoid this happening, turn off the engine. You can test the system of your car by turning the key to the "on" position and then back to the "off" position. You should hear a chime to indicate that the process was successful. The door locks will cycle.
Certain cars with more modern technology have rolling key technology that prevents thieves from using a stolen car's key to start it. This feature is still vulnerable to a technique known as a replay attack, which allows thieves to record the signal of the vehicle's key fob and reproduce it later to unlock the car. To combat this, manufacturers introduced security features known as the CAN bus protocols to prevent hacking.
Some manufacturers also use special encryption on their key fobs, which are not decoded by an ordinary program. These kinds of cars require programming by a professional, and you should only try this with someone who has experience with electronic devices. Check the manual of your car or visit the website of the manufacturer to find out how to program it. The steps to follow will differ according to the type of vehicle.
Transponder chips
Car keys with transponder chips need special programming to function. Any hardware store can offer you a new car key however the real challenge lies in integrating it with your car. A key that has been reprogrammed will need to be matched with the exact identification number of your car or else it won't be able to start the engine.
Transponder chips, which are used to stop theft of cars are a standard feature of modern automobiles. The chip is a small microcircuit that transmits a radio-frequency signal when the ignition key is put in. The car can detect the signal and begins the engine only if the signal is in line with the original that was programmed into the vehicle. The car will also shut down if a frequency is invalid. This makes it more difficult for novice car thefts to hot-wire a vehicle and then start it.
The key and the chip are linked by a circuit board that includes an induction coil. When the key is put in the ignition it creates a magnetic field created around the transponder. This creates a signal that is amplified by the coil which then transmits it to key's identification number. The ID number of the key is transmitted back to the vehicle and if it matches the engine will start.
There are many ways to program a transponder key but they all involve using an appropriate tool. You can buy these tools online or from most locksmiths for cars. These tools are not cheap but are essential for programming your car's chip.
You can also use a reprogrammable transponder key that was previously programmed for a different vehicle. In this case, you'll need to make sure that the key has not been damaged or the transponder has been altered in any way. You can read the chip using a scanner, or a computer that has a USB connector.
Reprogramming an transponder is a simple procedure, but requires specialized software. It also requires an scanner tool. If you're just beginning, it's best to seek help from an auto locksmith. Avoid buying used keys as they may already be programmed and won't work with your vehicle.
EZ Installer
Until recently the time when car owners wanted to replace their key fob were forced to visit a dealer to have it digitally 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 available only to dealers. The EZ Installer from Car Keys Express solves this issue for locksmiths and retailers by making it easier for pairing modern keys with vehicles.

The EZ Installer is compatible with all modern vehicles, including those that have proximity keys or push-button start. Check the compatibility guide at Tom's website to determine whether your vehicle is compatible.
If the device fails to program the remote or 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 fees. It can be used for as long as a key professional or retailer requires. The EZ Installer eliminates the need for costly monthly service contracts and software updates. This lets retailers save money while offering their customers the same high quality service as OEM equipment.
