You can reprogram your key fobs at home, however you must know the right process. To get the best results, you must have the following items:
Keys
Most modern vehicles require some kind of transponder key or fob in order to operate, providing security and anti-theft protection. The keys have to be programmed to your specific vehicle and its systems by a certified locksmith or dealer. They are expensive to replace if lost therefore, it is recommended to keep spare keys in the car. You can purchase replacement key fobs in online stores and many brick and mortar auto shops. How do you ensure that the one you have bought is authentic? Can you tell whether it has been programmed for a different vehicle or if it is able to be programmed to work with your car?
If you are planning to program a new key first, you need to make sure that your car is operating. Insert the key you wish to reprogramme into the ignition, but do not turn it. You only have a few seconds before the car's system reverts the commands and exits programming mode. It is important that you move quickly and don't delay between each step. Stop the engine to stop this. Change the key from "on" to "off" to test the system. You should hear a sound indicating that the process was successful. The door locks will be able to cycle.
Certain vehicles of recent years use rolling keys to keep thieves from using stolen keys to start the vehicle. This feature is still vulnerable to a technique dubbed replay attack, which allows thieves to record the signal from the vehicle's key fob and reproduce it later to open the car. To prevent this, manufacturers added security features known as the CAN bus protocols to prevent hackers from gaining access to the vehicle.
Some manufacturers use a special encryption on their keys that can't be decoded with an easy program. You should only try this method if you have experience is with electronic devices. Consult your car's manual or go to the manufacturer's website 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 special reconfiguration to work. Any hardware store can offer you a new car key however the real challenge lies in integrating it with your vehicle. The key needs to be programmed to match the exact identification number on your car, or else it won't be able to start.
Transponder chips, used to stop theft of cars, are a common feature of modern cars. The chip is a microcircuit which transmits a radio frequency signals when the key is inserted in the ignition. The car can detect the signal, and starts the engine only if the signal is in line with the original one that was programmed in the vehicle. The vehicle is also programmed to stop when it detects an incompatible frequency. This makes it harder for novice car thefts to hot-wire a vehicle and then start it.
A circuit board with an induction coil connects the key to the chip. When the key is placed in the ignition the magnetic field is generated around the transponder. This produces a signal which is taken up by the coil, which transmits it to the key's identification number. The key's identification number is then sent back to the car and the engine is started if the identification number matches.
There are many ways to program a transponder, however each requires a special tool. You can buy these tools on the internet or at many locksmiths in the automotive industry. These tools aren't expensive, but they are essential for programming the chip in your car.
You could also use a unreprogrammable key that was programmed for a different vehicle. In this scenario you'll need sure that the key isn't damaged or that the transponder has been altered in any way. To check this, you can use scanners or computers with an USB port to scan the chip and determine its identity.
Reprogramming the transponder is a straightforward procedure, but it requires special software. It also requires the use of a scanner. If you're just beginning it is recommended to seek help from an auto locksmith. Don't buy used keys since they could already be programmed and won't work with your vehicle.
