Reprogramming Car Keys
Transponder keys for car keys are believed to make vehicles more secure and harder for thieves to duplicate. The key could need to be reprogrammed in event of damage or lost.
You can change the key fobs you own but you must be aware of the correct process. You should have these items to achieve the most effective results:
Keys
Most modern cars require a transponder key in order to operate. This is a security feature and anti-theft protection. The keys are programmed by a locksmith or authorized dealer to work with the car's systems and the specific model. They are costly to replace if they are lost and it is recommended to keep spare keys in the car. You can locate key fobs to replace them in online stores as well as many brick-and mortar auto shops. How can you be sure that the key you purchased is authentic? Do you know if it has been programmed for a different vehicle or if it is able to be reprogrammed to fit your vehicle?
If you're looking to program a new key, the first step is to ensure that your vehicle is running. Insert the key that you'd like to reprogramme into your ignition, but don't turn it. You will only have just a few seconds before the car's system reverts the commands and leaves programming mode. It is crucial to move quickly and do not wait between each step. Shut off the engine to stop this. Turn the key from "on" to "off" to test the system. The door locks should cycle and you'll hear a chime to indicate that the process has been successful.
Certain newer vehicles utilize rolling keys to stop thieves from using stolen keys to open the vehicle. The technology is still susceptible to a technique dubbed replay attacks which allows thieves to record the signal of the key fob of the car, then reproduce it to unlock the car. To prevent this, manufacturers have added an additional security feature known as the CAN bus protocol to thwart hacking attempts.
Certain manufacturers also have special encryption on their key fobs which cannot be decoded by an easy program. These types of vehicles require programming by a professional. Therefore, you should only attempt this process only if you've worked with electronic devices. Check the manual of your car or go to the manufacturer's website for information on how to program it. The steps to follow will differ depending on the model of vehicle.
Transponder chips
Car keys with transponder chips require a specific reprogramming to work. While any hardware store can cut a new key for you, the main problem is to make it work to work with the specific car you own. The key has to be programmed to match the exact identification number of your car, or else it will not start.
Transponder chips are a standard feature of modern automobiles and are designed to stop car theft. The chip is a microcircuit which transmits a radio frequency signals when the key is inserted into the ignition. The car is able to detect the signal and begins the engine only if the signal matches the original one that was programmed into the vehicle. The car is also programmed to stop if it detects an invalid frequency. This makes it much harder for car thieves with no experience to hot wire a vehicle and start it.
A circuit board that has an induction coil connects the chip to the key. When the key is inserted into the ignition it creates an electric field around the transponder. This generates a signal that is taken up by the coil and sent to the key's identification. The key's ID number is then sent back to the vehicle and if it matches, the engine will start.
There are a few different ways to program a transponder keys, however, they all require an instrument that is specifically designed for the purpose. These tools can be purchased on the internet or at most auto locksmiths. They're not cheap, but they are vital for programming the chip to your car.
You can also use a reprogrammable transponder key that was previously programmed for a different vehicle. In this case, make sure that the key isn't damaged or that the transponder isn't altered in any way. To do this, you can use scanners or computers equipped with an USB port to scan the chip and determine its identity.
Reprogramming an transponder is a simple procedure, but requires specialized software. It also requires an scanner tool. If you're just beginning it is recommended to seek out the help of an auto locksmith. Don't buy used keys since they could already be programmed and will not work with your vehicle.
EZ Installer
Prior to recently the time when car owners wanted to replace their key fob were forced to go to an agent to have it electronically linked to the vehicle. This is because modern keys have to be "paired" to a specific vehicle to function in a way that 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 for retailers and locksmiths.
The EZ Installer is a basic, "plug and play" OBD device that pairs new keys to vehicles, without the need for complex equipment or programming tokens. It works by connecting 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 models, including those with proximity keys or push button start. To see if it will work for a particular vehicle, refer to the compatibility guide on Tom's website.
A money-back guarantee of 100% is offered in the event that the device fails to successfully program a remote or key purchased from Tom's for a vehicle compatible.
Unlike traditional programming equipment that can cost retailers and key professionals thousands of dollars in typical per-key "token" costs, the EZ Installer Pro doesn't charge any fees and can be used as long as a key professional wishes to keep it. The EZ Installer also eliminates the requirement for expensive monthly service contracts and updates, so it can save retailers money while offering customers the same high-quality service as OEM equipment. It also offers a top warranty that covers hardware and software for the remainder of your life.
