Reprogramming Car Keys
Car keys with transponders are believed to make vehicles more secure and more difficult for thieves to duplicate. However, a key might need to be reset if it becomes damaged or lost.
You can program key fobs yourself, but you must know the correct procedure. It is essential to have these items to get the most effective results:
Keys
Almost all modern cars require some kind of transponder key or fob to work, which provides security and protection against theft. The keys are programmed by a locksmith or authorized dealer to function with the car's systems and the specific model. They are costly to replace in the event of loss therefore, it is recommended to keep spare keys in the car. You can also find replacement key fobs on various websites and in many brick-and-mortar auto shops. How can you know that the one you bought is genuine? Do you know if the unit has been programmed to work with a different vehicle or if it could be programmed differently?
To program a new car key you must first verify that your vehicle is operating. Insert the key that you'd like to reprogramme into the ignition, but don't turn it. There are only just a few seconds before the car's system reverts the commands and then exits programming mode. Therefore, it is crucial to be quick and not be able to wait between steps. Stop the engine to avoid this. Turn the key from "on" to "off" to test the system. You should hear a chime signalling that the procedure was successful. The door locks will be able to cycle.
Certain newer vehicles have rolling key system, which stops thieves from using a stolen vehicle's key to open it. This technology is still vulnerable to a technique dubbed a replay attack which allows thieves to record the signal from the vehicle's key fob, then reproduce it to unlock the car. To stop this, manufacturers have added a security feature called CAN bus protocol to thwart hacking attempts.
Certain manufacturers also have special encryption on their key fobs, which are not decoded by an easy program. You should only try this process if your experience is with electronics. It is a good idea to read the owner's manual for your car or search for the manufacturer online, as the steps differ based on vehicle type.
Transponder chips
Car keys with transponder chips require a special reprogramming to work. While any hardware store can cut a new key for you, the real issue is how to integrate it in conjunction with your particular car. The key has to be programmed to match the exact identification number on your vehicle, or else it won't be able to start.
Transponder chips, which are used to prevent car theft are a standard feature of modern cars. The chip is a microcircuit which emits a radio frequency signal when the key is placed into the ignition. The car then recognizes the signal and then starts the engine if it is in line with the original frequency that was programmed into the vehicle. The car also shuts down if the frequency is invalid. This makes it much harder for novice car thieves to wire a vehicle and start it.
The chip and the key are connected via the circuit board which includes an induction coil. When the key is placed in the ignition the magnetic field is created 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 ID number is transmitted back to the vehicle, and if it matches, the engine will start.
There are a few different ways to program a transponder key however, all require an instrument that is specifically designed for the purpose. You can buy these tools on the internet or at many locksmiths for cars. These tools are not inexpensive, but they are vital for programming the chip in your car.
You could also use a unreprogrammable key that was programmed for a different vehicle. In this case, make sure that the key has not been damaged or the transponder has not been altered in any way. You can read the chip using a scanner, or a computer with an USB connector.
Reprogramming the transponder key is simple, but it requires an expertly designed software and scan tool. It's best to ask an auto locksmith for assistance if you're a novice. Avoid buying used keys as they may already be programmed and will not be compatible with your vehicle.
EZ Installer
For a long time, car owners who required replacement of their key fob had no choice than to visit a dealership to have their key linked to their vehicle. This is because modern keys need to be "paired" to a specific vehicle to function and work, which required the use of expensive and complex equipment that only dealers had access to. The EZ Installer by Car Keys Express simplifies the process of pairing modern keys with vehicles used by retailers and locksmiths.
The EZ Installer, a simple "plug-and-play" OBD device, connects new keys to vehicles without the use of complicated equipment or tokens for programming. It connects directly to the vehicle's standard OBD port and utilizing a mobile app to provide easy-to-follow instructions. The EZ Installer is compatible with most newer vehicles, including those with proximity keys or push button start. To determine if it'll be compatible with your specific vehicle, look up the compatibility guide on the Tom's website.
If the device fails to program a remote or key purchased from Tom's into a vehicle that is compatible then a full refund is offered.
Contrary to conventional programming equipment which costs key retailers and professionals hundreds of thousands of dollars in "token" fees per key, the EZ Installer Pro does not charge these fees. It is able to be used as long as a key professional or retailer requires. The EZ Installer also eliminates the need for costly monthly service contracts and updates, meaning that it will save retailers money while still providing customers with the same high-quality service as OEM equipment. It also offers a leading warranty that covers hardware and software for the remainder of your life.
