Keys
Modern cars require a transponder key in order to operate. This provides security and protection against theft. The keys have to be programmed to your specific vehicle and its systems by a licensed dealer or locksmith. They are costly to replace if lost and you should keep extras handy. You will also find replacement key fobs at various online stores and in many brick-and-mortar auto shops. How can you know that the one you purchased is genuine? Are you able to tell if the unit has been programmed to work with another vehicle, or if it can be programmed car keys again?
To program a new car keys, you must first ensure that your vehicle is running. Insert the key you want to reprogramme into your ignition, but do not turn it. There are only a few seconds left before the system resets all commands and then exits the programming mode. It is important that you be quick and don't delay between each step. Shut off the engine to stop this. Change the key from “on” to “off” to test the system. The door locks should cycle and you'll hear a chime signalling that the process has been successful.
Certain vehicles of recent years use rolling keys to keep thieves from using stolen keys to start the car. This feature is still vulnerable to a technique known as a replay attack. It allows thieves to record and reproduce the signal from the car key fob to open the car keys programmed. To stop this, manufacturers added security features known as the CAN bus protocols to ward off hackers from gaining access to the vehicle.
Some manufacturers use a special encryption on their keys, which cannot be decoded using a simple program. You should only try this method if your previous experience is with electronics. Refer to the manual for your car key programming cost or visit the website of the manufacturer for information on how to program it. The steps will vary according to the type of vehicle.
Transponder chips
Car keys that feature transponder chips need special reconfiguration to work. Any hardware store can offer you a new car key, but the real challenge is in implementing it to your vehicle. The key has to be programmed to match the exact identification number of your car, or else it will not start.
Transponder chips, which are used to stop theft of cars, are a common feature of modern cars. The chip is a small microcircuit that emits a radio frequency signal when the ignition key is placed. The car then detects the signal and starts the engine if it is in line with the original signal that was programmed into the vehicle. The car also shuts down if a frequency is not valid. This makes it much harder for novice car thieves to wire a vehicle and then start it.
A circuit board that has an induction coil connects the key to the chip. When the key is put in the ignition it creates a magnetic field generated around the transponder. This generates a signal that is amplified by the coil which sends it to the key's identification number. The key's identification number is then transmitted back to the car and the engine is started if the identification number matches.
There are a variety of methods to program a key transponder, but all of them require a special tool. You can buy these tools on the internet or at many locksmiths in the automotive industry. They are not cheap, but they are vital for programming the chip in your car.

In this instance you'll need sure that the key is not damaged or the transponder been altered in any way. You can read the chip using a scanner, or a computer equipped with the USB connector.
Reprogramming the transponder is a straightforward procedure, but requires specialized software. It also requires the use of a scanner.
