Keys
Nearly all modern vehicles require a transponder fob or transponder keys to operate, ensuring security and protection against theft. The keys are programmed by a locksmith or authorized dealer to work with your car's system and specific model. They are costly to replace in the event of loss therefore, it is recommended to keep spare keys in the car.

If you are planning to program an entirely new key, the first step is to ensure that your car is on and running. Insert the key you wish to reprogram into the ignition without turning it. There are only a couple of seconds before the car's system resets commands and then exits programming mode. It is important that you move quickly and don't be patient between each step. Turn off the engine to prevent this. Change reprogram car key from "on" to "off" to test the system.

Certain newer vehicles utilize rolling keys to keep thieves from using stolen keys to open the vehicle. The technology is still susceptible to a technique dubbed replay attacks that allows thieves to record the signal of 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 stop hackers from gaining access to the vehicle.
Certain manufacturers employ a specific encryption on their keys that can't be decoded with a simple program. You should only attempt this method if you have experiences are with electronic devices. It is recommended to refer to the owner's manual for your car or look up the manufacturer on the internet, since these steps vary by vehicle type.
Transponder chips
Car keys with transponder chips require special reconfiguration to work. Any hardware store can offer you an entirely new car key, however the real challenge lies in making it work with your vehicle. The key needs to be programmed to match the exact identification number of your vehicle, or else it will not start.
Transponder chips, which are used to stop theft of cars, are a common feature of modern automobiles. The chip is a small microcircuit that emits a radio frequency signal when the ignition key is inserted. The car then scans for the signal and starts the engine in case it matches the original frequency that was programmed into the vehicle. The car also shuts down if the frequency is invalid. This makes it more difficult for thieves who aren't experienced 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 placed in the ignition the magnetic field is created around the transponder. This generates a signal, which is taken up by the coil before being sent to the key's identification number. The key's identification number is returned to the car, and the engine starts if the identification number matches.
There are a few different ways to program a transponder key, however, all require an instrument that is specifically designed for the purpose. These tools can be bought 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 instance you'll need sure that the key isn't damaged or that the transponder has been altered in any way. The chip can be read with a scanner, or a computer that has an USB connector.
Reprogramming the transponder is a straightforward process, but requires specialized software. It also requires an scanner tool. It is recommended to contact an auto locksmith for assistance for those who are new to the process. Avoid buying used keys as they could already be programmed, and they won't work with your vehicle.
