Keys
Nearly all modern vehicles require some kind of transponder key or fob in order to operate, providing security and protection against theft. The keys must be programmed to your specific vehicle and its features by a licensed locksmith or dealer. They are costly to replace in the event of loss and you should have spares in your car. You can locate replacement key fobs in online stores as well as many brick-and mortar auto shops. How can you know that the one you bought is genuine? Do you know 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 ensure that your car is running. Insert the key that you wish to program into the ignition, but don't turn it. There are only a few seconds before the system resets all commands and then exits the programming mode. It is important that you move quickly and don't delay between each step. Turn off the engine to avoid this. You can test the car's security system by turning the key to the "on" position and back to the "off" position. You should hear a sound to indicate that the process was successful. The door locks will go through a cycle.
Some newer vehicles use rolling keys to stop thieves from using stolen keys to open the vehicle. The technology is still susceptible to a technique known as replay attack, which allows thieves to record the signal from the key fob on the vehicle and reproduce it later to unlock the car. To stop this, manufacturers have introduced a security feature called CAN bus protocol to prevent attacks on hacking.
Some manufacturers also use special encryption on their key fobs which are not decoded by a simple program. These types of vehicles require to be programmed by a professional, and you should only attempt this process with someone who has experience with electronics. Consult your car's manual or visit the website of the manufacturer to find out how to program it. The steps are different depending on the model of vehicle.
Transponder chips
Car keys that feature transponder chips require a special reprogramming to work. Any hardware store can give you a new car key however the real challenge lies in integrating it with your vehicle. The key has to be programmed to match the exact identification number of your vehicle, or else it won't start.
Transponder chips, used to protect cars from theft, are a common feature of modern cars. The chip is a small microcircuit that emits a radio frequency signal when the ignition key is put in. The car detects the signal, and starts the engine only if it matches the original that was programmed into the vehicle. The car also shuts down if the frequency is invalid. This makes it harder for novice car thefts to connect a vehicle to a hot wire and then start it.
The chip and the key are connected via an electronic circuit board that contains an induction coil. 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 sent to the key identification number. The key's ID number is sent back to the vehicle, and if it matches the engine will begin to run.
There are a variety of ways to program a transponder, but each requires a special tool. You can purchase these tools online or at most locksmiths for cars. They are not cheap, but they're vital for programming the chip in your vehicle.
You could also use a unreprogrammable key that was programmed for an alternative vehicle. In this instance you'll need sure that the key has not been damaged or that the transponder has been altered in any way. To accomplish this, you can use scanners or computers equipped with a USB port to read the chip and determine its identity.
Reprogramming a transponder is a simple procedure, but it requires specific software. It also requires the use of a scanner. It is recommended to contact an auto locksmith for help in case you're not an expert. Avoid buying used keys because they could already be programmed and won't be compatible with your vehicle.
