Reprogramming Car Keys
Car keys with transponders are thought to keep vehicles more secure and harder for thieves to duplicate. However, a key might require reprogramming in the event that it is damaged or lost.
You can change the key fobs you own, but you must know the correct process. For the best results, you must have the following items:
Keys
Almost all modern cars require a transponder key or fob in order to operate, providing security and anti-theft protection. These keys are programmed by a locksmith or an authorized dealer to function with your car's systems and specific model. They are costly to replace if they are lost, so you should keep extras handy. You can 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 genuine? Are you able to tell if it has been programmed to work with another vehicle or if it is able to be reprogrammed to fit your vehicle?
To program a new car key, you must first verify that your vehicle is running. Insert the key you want to reprogram into the ignition, but do not turn it. There are only a few seconds left before the system will reset all commands and then exits the programming mode. Therefore, car key cutting and programming is important to move quickly and not wait between steps. Stop the engine to stop this. You can test the car's security system by turning the key to the "on" position, then back to the "off" position. The door locks should be able to cycle, and you will hear a sound that indicates that the process was successful.
Certain newer vehicles utilize rolling keys to stop thieves from using stolen keys to start the car. This feature is still susceptible to a technique called a replay attack. It allows thieves to record and then reproduce the signal received from the car key fob to open the car. To counter this, manufacturers have introduced a security feature called CAN bus protocol to stop attacks on hacking.
Certain manufacturers employ a specific encryption on their keys that cannot be decoded using an easy program. It is best to only attempt this process if your experience is in electronic devices. Check the manual of your car or go to the manufacturer's website for information on how to program it. The steps will vary according to the type of vehicle.
Transponder chips
Car keys that feature transponder chips need special programming to function. While any hardware store can cut keys for you, the real challenge is making it function with your specific car. A reprogrammed key will need to match the specific identification number of your car otherwise it won't even start the engine.
Transponder chips, which are used to protect cars from theft, are a common feature of modern automobiles. The chip is a microcircuit which transmits a radio frequency signal when the key is inserted into the ignition. The car then scans for the signal and begins the engine in case it matches the original frequency that was programmed into the vehicle. The car is also programmed to stop when it detects an incorrect frequency. This makes it more difficult for thieves with no experience to connect a vehicle to a hot wire and then start it.
A circuit board equipped with an induction coil connects the chip to the key. When the key is placed in the ignition it creates an electromagnetic field around the transponder. This generates a signal that gets absorbed by the coil, which then transmits it to key's identification number. The key's identification number is then sent back to the car and the engine is started when the identification number matches.
There are a variety of ways to program a key transponder, however each requires an instrument that is specifically designed for. These tools are available on the internet or at most auto locksmiths. These tools are not expensive, but they are essential for programming the chip in your car.
You can also use a reprogrammable transponder key that was previously programmed for another vehicle. In this scenario you'll need sure that the key is not damaged or that the transponder has been altered in any way. To check this, you can use a scanner or a computer with a USB port to scan the chip and determine its identity.
Reprogramming a transponder is a simple procedure, but it requires special software. It also requires a scanner tool. If you're new to the process it is recommended to seek the assistance of an auto locksmith. Avoid buying used keys because they could already be programmed and will not work with your car.
EZ Installer
In the past, car owners who wanted to replace their key fob were forced to visit an agent to have it electronically paired with the vehicle. It is because 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 by Car Keys Express simplifies the process of pairing up modern keys to vehicles for retailers and locksmiths.
The EZ Installer is a simple, "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 utilizing an app for mobile devices to provide simple instructions. The EZ Installer is compatible with the majority of newer vehicles, including those with proximity keys or push button start. Visit the compatibility guide on Tom's website to determine if your vehicle is compatible.
If the device is unable to program a remote or key purchased from Tom's into a vehicle compatible then a full refund is offered.
In contrast to traditional programming equipment that can cost retailers and key professionals thousands of dollars with typical per-key "token" fees, the EZ Installer Pro doesn't charge these fees at all and can be used for as long as a retailer or key professional wishes to use it. The EZ Installer also eliminates the requirement for expensive monthly service contracts and updates, so it can save retailers money while still providing customers with the same high-quality service as OEM equipment. It also comes with an industry-leading warranty that includes all software and hardware for the life of the product.
