You can change the programming of your key fobs at home, however you need to be aware of the correct procedure. You should have these items to achieve the most effective results:
Keys
Most modern cars require a transponder key in order to operate. This gives security and protection against theft. The keys are programmed by a locksmith or an authorized dealer to function with your car's systems and specific model. It's costly to replace them if they're lost, so it's a good idea to keep extras on hand. You can also find replacement keys fobs in various online stores and in many brick-and mortar auto shops. How can you know that the one you purchased is genuine? Are you able to tell whether it was programmed to work with another vehicle or if it could be reprogrammed for yours?
If you're looking to program an entirely new key the first step is to ensure that your vehicle is on and running. Insert the key you want to reprogram into the ignition without turning it. There are only a few seconds left before the system will reset all commands and then exits the programming mode. Therefore, it is essential to move quickly and not be able to wait between steps. To prevent this from happening, shut off the engine. You can check the car's security system by turning the key to the "on" position, then back to the "off" position. The door locks should cycle, and you will hear a sound that indicates that the procedure was successful.
Certain newer vehicles utilize rolling keys to stop thieves from using stolen keys to start the vehicle. This feature is still vulnerable to a technique known as replay attack. It allows thieves to record and later reproduce the signal received from the key fob of the vehicle to open the car. To combat this, manufacturers introduced a security feature known as the CAN bus protocols to ward off hackers from gaining access to the vehicle.
Certain manufacturers have a unique encryption on their keys that cannot be decoded by an easy program. You should only attempt this process if your experience is with electronic devices. Consult your car's manual or visit the manufacturer's website for information on how to program it. The steps will vary depending on the type of vehicle.
Transponder chips
Transponder chip car keys require a special reprogramming to work. Any hardware store can give you an entirely new car key, but the real challenge lies in making it work with your vehicle. The key needs to be programmed to match the exact identification number of your vehicle, or else it won't start.
Transponder chips are a common feature of modern cars and are designed to stop car theft. The chip is a microcircuit which emits a radio frequency signal when the key is placed in the ignition. The car is able to detect the signal and begins the engine only if the signal is in line with the original that was programmed in the vehicle. The car is also programmed to shut down when it detects an incorrect frequency. This makes it much harder for thieves who are not experienced to hot wire a vehicle and then start it.
The key and the chip are connected via a circuit board that includes an induction coil. When the key is placed in the ignition, it creates an electric field around the transponder. This creates a signal that gets absorbed by the coil, which transmits it to the key's identification number. The key's identification number is then sent back to the car, and the engine starts if the identification number matches.
There are several methods to program a transponder key, however, all require an instrument that is specifically designed for the purpose. These tools are available on the internet or at most auto locksmiths. These tools aren't expensive, but they are essential for programming the chip in your car.
You can also use an unreprogrammable key that was programmed for an alternative vehicle. In this scenario you'll need sure that the key has not been damaged or the transponder has been altered in any way. You can read the chip by using a scanner or a computer equipped with the USB connector.
Reprogramming an transponder is a simple procedure, but requires specific software. It also requires a scanner tool. It is best to consult an auto locksmith for help in case you're not an expert. Avoid buying used keys as they might already be programmed, and they won't work with your vehicle.
EZ Installer
For decades, car owners who needed to replace their key fob had no other choice than to visit a dealership to have their key electronically linked to their vehicle. This is because in order to make modern keys work, they need to be "paired". This required expensive and complicated equipment that was available only to dealers. The EZ Installer from Car Keys Express solves this problem for locksmiths and retailers by easing the process of connecting modern keys to vehicles.
The Easy Installer, a straightforward "plug-and-play" OBD device, pairs new keys with vehicles without the need for complex equipment or tokens for programming. It connects directly to the vehicle's standard OBD port, and then using an app for mobile devices to provide simple instructions. The EZ Installer works with a wide range of modern vehicles that include proximity keys or push-button start. To see if it will be compatible with your specific vehicle, refer to the compatibility guide on the Tom's website.
A full money-back guarantee is offered if the device does not successfully program a remote or key purchased from Tom's for a vehicle that is compatible.
Unlike traditional programming equipment that costs key professionals thousands of dollars through typical per-key "token" fees, the EZ Installer Pro doesn't charge these fees at all, so it can be used for as long as a retailer or key professional wishes it to be. The EZ Installer eliminates the need for costly monthly service contracts and software updates. This allows retailers to save money while offering their customers the same high quality service as OEM equipment. It also offers a leading warranty that covers both hardware and software for the rest of your life.
