Reprogramming Car Keys
Car keys with transponders are thought to keep vehicles safer and are less likely to be duplicated by thieves. A key may have to be programmed again in the case of damage or lost.
You can reprogram key fobs yourself but you must be aware of the correct process. For the best results you should have the following items:
Keys
Nearly all modern vehicles require some kind of transponder key or fob to operate, providing security and protection against theft. These keys are programmed by a locksmith or an authorized dealer to work with your car's systems and the specific model. They are expensive to replace if lost and it is recommended to keep spare keys in the car. You can locate key fobs that can be replaced in online stores and numerous brick-and-mortar auto shops. How can you ensure that the one you bought is authentic? Can you tell whether the unit has been programmed to work with a different vehicle or if it could be programmed differently?
If you're looking to program a new key first, you need to ensure that your vehicle is on and running. Insert the key you want to program into the ignition, but do not turn it. You only have just a few seconds before the car's system resets commands and leaves programming mode. It is crucial to move quickly and don't delay between each step. Stop the engine to prevent this. Switch the key from "on" to "off" to test the system. The door locks should cycle, and you will hear a chime to indicate that the process was successful.
Certain vehicles of recent years use rolling keys to keep 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 open the car. To stop this, manufacturers have introduced a security feature called CAN bus protocol to stop hacking attempts.
Certain manufacturers also employ special encryption on their key fobs, which cannot be decoded by an ordinary program. These types of cars require programming by a professional, and you should only attempt this procedure if you have experience working with electronics. Refer to the manual for your car or look up the manufacturer's website to learn how to program it. The steps to follow will differ depending on the type of vehicle.
Transponder chips
Transponder chip car keys require special reprogramming in order to function. While any hardware store can cut a new key for you, the main challenge is making it function to work with the specific car you own. The key must be programmed to match the exact identification code on your car, otherwise it will not start.
Transponder chips, which are used to prevent car theft, are a common feature of modern automobiles. The chip is a small microcircuit which transmits a radio-frequency signal when the ignition key is placed. The car is able to detect the signal and starts the engine only if the signal is in line with the original one that was programmed into the vehicle. The car is also programmed to stop when it detects an incompatible frequency. This makes it much more difficult for thieves who are not experienced to connect a vehicle with hot wires and then start it.
The key and the chip are connected via the circuit board which includes an induction coil. When the key is placed in the ignition it creates an electric field around the transponder. This creates a signal which is taken up by the coil before being 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 several ways to program a transponder, but all of them require the use of a specific tool. You can purchase these tools online or from most locksmiths in the automotive industry. They are not cheap, but they're vital for programming the chip in your vehicle.
You can also use an resettable key that was programmed for an alternative vehicle. In this instance you'll need sure that the key is not damaged or that the transponder has been altered in any way. To accomplish this, you'll need scanners or a computer equipped with a USB port to scan the chip and determine its identity.
The process of reprogramming a transponder key is quite simple, but it requires specialized software and a scan tool. If you're new to the process you should seek out the help of an auto locksmith. Avoid buying used keys because they could already be programmed and won't 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 a dealer to have it digitally paired to the vehicle. It is because for modern keys to function they have 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 with vehicles used by locksmiths and retailers.
