Keys
Most modern vehicles require a transponder key or fob to work, which provides security and anti-theft protection. These keys must be programmed to the specific vehicle and its systems by a licensed locksmith or dealer. They are expensive to replace if they are lost therefore, you should keep extras handy. You will also find replacement key fobs on various websites and in a variety of brick-and-mortar automotive shops. How can you ensure that the one you bought is authentic? Do you know whether it has been programmed for a different vehicle or if it can be reprogrammed for yours?
If you want to program a new key, the first step is to make sure that your car is operating. Insert the key you wish to reprogram into the ignition without turning it. You will only have a couple of seconds before the car's system resets commands and then exits programming mode. Therefore, it is essential to move quickly and not wait between steps. Stop the engine to prevent this. You can check the car's system by turning the key to the "on" position and then back to the "off" position. The door locks should cycle, and you'll hear a sound that indicates that the process has been successful.
Some newer vehicles use rolling key technology to prevent thieves from using stolen keys to open the car. This feature is still vulnerable to a technique known as a replay attack, which allows thieves to record the signal received from the key fob of the car and reproduce it later to unlock the car. To stop this, manufacturers have introduced a security feature called CAN bus protocol to stop hacking attempts.
Some manufacturers use a special encryption on their keys that cannot be decoded using an easy program. These kinds of cars require programming by a professional, so you should only attempt this process only if you've worked with electronic devices. Check the manual of your car or look up the website of the manufacturer to learn how to program it. The steps will vary depending on the model of vehicle.
Transponder chips
Car keys that feature transponder chips require special reprogramming to work. While any hardware store can cut keys for you, the biggest challenge is making it function to work with the specific car you own. A reprogrammed key will need to be compatible with the exact identification number of your vehicle or else it won't be able to start the engine.
Transponder chips are a typical feature of modern automobiles and are designed to prevent car theft. The chip is a small microcircuit which transmits a radio-frequency signal when the ignition key is put in. The car detects the signal and starts the engine only if the signal is in line with the one programmed into the vehicle. The car will also shut down if the frequency is not valid. This makes it more difficult for novice car thieves to hot wire a vehicle and then start it.
A circuit board with an induction coil connects the chip to the key. When the key is inserted into the ignition it creates an electromagnetic field around the transponder. This generates a signal that is taken up by the coil and then transmitted to the key's identification. The key's identification code is returned to the car and the engine is started if the identification number matches.
There are a few different methods to program a transponder keys, however, all require a special tool. These tools are available through the internet or from many automotive locksmiths. They are not cheap, but they're crucial for programming the chip into your vehicle.
You can also use an reprogrammable key that was previously programmed for an alternative vehicle. In this case, make sure the key hasn't been damaged or the transponder isn't altered in any way. The chip can be read using a scanner, or a computer equipped with a USB connector.
Reprogramming a transponder key is quite easy, but it will require special software and a scanning tool. If you're just beginning you should seek out the help of an auto locksmith. Avoid buying used keys as they might already be programmed and won't work with your car.
