Keys
Modern cars require a transponder key to operate. This is a security feature and anti-theft protection. The keys have to be programmed to your particular vehicle and its features by a licensed locksmith or dealer. They can be costly to replace if they are lost, so you should keep extras handy. You can find key fobs to replace them in online stores and many brick-and mortar auto shops. How can you ensure that the one you purchased is genuine? Can you tell whether the unit has been programmed to work with another vehicle or if it could be programmed differently?

There are just a few minutes before the system will reset all commands and leaves the programming mode. It is essential to move quickly and don't delay between each step.

Certain vehicles of recent years use rolling key technology to prevent thieves from using stolen keys to start the vehicle. The feature is still vulnerable to a technique dubbed replay attack. It allows thieves to record and later reproduce the signal from the key fob of the vehicle to unlock the car. To counter this, manufacturers have added a security feature called the CAN bus protocol to prevent attacks on hacking.
Some manufacturers also use special encryption on their key fobs which cannot be decoded by an ordinary program. You should only try this method if your previous experience is with electronics.

Transponder chips
Transponder chip car keys require special reprogramming in order to work. Any hardware store can offer you a new car key, but the real challenge lies in implementing it to your car. A key that has been reprogrammed will need to match the specific identification number of your car, or it won't start the engine.
Transponder chips are a standard feature in modern cars and are designed to stop car theft. The chip is a tiny microcircuit that emits a radio frequency signal when the ignition key is put in. The car detects the signal and begins the engine only if the signal matches the original one that was programmed into the vehicle. The car is also programmed to stop when it detects an incorrect frequency. This makes it much more difficult for thieves who are not experienced to wire a vehicle and then start it.
A circuit board that has an induction coil that connects the key to the chip. When the key is placed in the ignition it creates a magnetic field created around the transponder. This generates a signal that is received by the coil and sent to the key identification number. The key's ID number is transmitted back to the vehicle and if it is in line with the engine will begin to run.
There are several methods to program a key transponder, but each requires an instrument that is specifically designed for. You can buy these tools online or at most locksmiths in the automotive industry. They're not cheap, but they're essential for programming the chip into your car.
You could also utilize a transponder that is reprogrammable that has been previously programmed for another vehicle. In this instance, you must make sure the key isn't damaged or that the transponder isn't altered in any way. To check this, you'll need a scanner or a computer equipped with a USB port to scan the chip and determine its identity.
Reprogramming a transponder key is quite simple, however it requires an expertly designed software and scan tool. It is best to consult an auto locksmith for help for those who are new to the process. Avoid buying used keys as they could already be programmed and will not work with your car.
