Reprogramming Car Keys
Car keys with transponders are believed to make vehicles safer and are more difficult for thieves to duplicate. However, a key may require reprogramming in the event that it is damaged or lost.
You can reprogram your key fobs at home, however you need to be aware of the correct procedure. For the best results you must have the following items:
Keys
Almost all modern cars require a transponder fob or transponder keys to operate, providing security and anti-theft protection. The keys are programmed by a locksmith or an authorized dealer to function with your car's system and specific model. It is expensive to replace them if they are lost, so it's better to keep extras on hand. You will also find replacement key fobs on various websites and in many brick-and mortar auto shops. How can you be sure that the one you bought is authentic? Are you able to tell if it has been programmed for another car or if it could be reprogrammed for yours?
If you want to program a new key first, you need to ensure that your car is running. Insert the key you wish to program into the ignition, but do not turn it. You have just a few minutes before the system will reset all commands and then exits the programming mode. This is why it is crucial to move fast and not be able to wait between steps. Turn off the engine to avoid this. You can check the car's security system by turning the key to the "on" position, then back to the "off" position. You should hear a chime indicating that the process was successful. The door locks will be able to cycle.
Some newer cars use a rolling key technology, which prevents thieves from using stolen cars' key to open it. This feature is still vulnerable to a technique known as a replay attack. It allows thieves to record and later duplicate the signal generated by the car key fob to unlock the car. To prevent this, manufacturers introduced the security feature known as the CAN bus protocols to stop hacking.
Certain manufacturers have a unique encryption on their keys that cannot be decoded using an ordinary program. You should only try this method if you have experience is with electronics. Consult your car's manual or look up the manufacturer's website to learn how to program it. The steps are different according to the type of vehicle.
Transponder chips
Car keys with transponder chips require special reprogramming to work. While any hardware store can cut a new key for you, the main 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 car, otherwise it won't be able to start.
Transponder chips are a typical feature in modern cars and are designed to prevent car theft. The chip is a tiny microcircuit that emits a radio frequency signal when the ignition key is inserted. The car then scans for the signal and then starts the engine in case it matches the original frequency that was programmed into the vehicle. The car also shuts down if the frequency is not valid. This makes it much harder for novice car thieves to wire a vehicle and start it.
The chip and the key are connected by the circuit board which includes an induction coil. When the key is placed in the ignition it creates a magnetic field around the transponder. This creates a signal which is absorbed by the coil and sent to the key's identification number. The key's ID number is sent back to the vehicle, and if it matches the engine will start.
There are many ways to program a key transponder, however each requires an instrument that is specifically designed for. These tools can be bought online or from most automotive locksmiths. They're not cheap, but they are vital for programming the chip in your car.
You could also use a reprogrammable key that was previously programmed for an alternative vehicle. In this instance you'll need to make sure that the key isn't damaged or the transponder has been 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 a transponder is a simple process, but requires special software. It also requires the use of a scanner. It is best to consult an auto locksmith for assistance if you're a novice. Avoid buying used keys as they might already be programmed, and they won't be compatible with your vehicle.
EZ Installer
Until recently, car owners who wanted to replace their keys were required to go to an agent to have it electronically linked to the vehicle. This is because, in order to make modern keys function, they need to be "paired". This required expensive and complicated equipment that was only available to dealers. The EZ Installer from Car Keys Express solves this problem for retailers and locksmiths by making it easier for pairing modern keys with vehicles.
The Easy Installer is a straightforward, "plug and play" OBD device that pairs new keys with vehicles without the need for complex equipment or programming tokens. It works by connecting directly to the vehicle's standard OBD port, and then using an app for mobile devices to provide easy-to-follow instructions. The EZ Installer is compatible with most newer vehicles that have proximity keys or push button start. To determine if it'll work with a specific vehicle, check the compatibility guide on the Tom's website.
If the device is unable to program a remote or key purchased from Tom's into a vehicle that is compatible, a full refund is offered.
In contrast to traditional programming equipment that can cost retailers and key professionals thousands of dollars in typical per-key "token" charges, the EZ Installer Pro doesn't charge any fees, so it can be used as long as a key professional wishes to keep it. The EZ Installer eliminates the need for expensive monthly service contracts and software updates. This lets retailers save money while offering their customers the same top quality service as OEM equipment. It also comes with an industry-leading warranty that includes all software and hardware for life.
