Keys
Almost all modern cars require some kind of transponder key or fob to operate, ensuring security and anti-theft protection. These keys are programmed by a locksmith or an authorized dealer to work with your car's system and specific model. It's expensive to replace them if they're lost, so it's a good idea to keep extras on hand. You can purchase replacement key fobs in online stores, as well as numerous brick-and-mortar auto shops. How can you ensure that the key you purchased is authentic? Can you tell if the unit has been programmed to work with a different vehicle or if it could be reprogrammed?
To program a new car key you must first ensure that your car is running. Insert the key you want to program into the ignition, but do not turn it. There are only just a few seconds before the car's system resets commands and leaves programming mode. Therefore, it is essential to move fast and not pause between steps. To prevent this from happening, shut off the engine. Turn the key from "on" to "off" to test the system. The door locks should cycle and you will hear a chime signalling that the procedure was successful.
Certain cars with more modern technology have rolling key technology, which stops thieves from using a stolen car's key to start it. The feature is still vulnerable to a technique dubbed a replay attack. It allows thieves to record and then duplicate the signal generated by the key fob of the vehicle to open the car. To counter this, manufacturers have introduced a security feature called the CAN bus protocol to thwart hacking attempts.
Some manufacturers also use special encryption on their key fobs that cannot be decoded with an easy program. You should only attempt this process if your experiences are with electronic devices. It is a good idea to refer to the owner's manual for your car or search for the manufacturer on the internet, since the steps differ based on vehicle model.
Transponder chips
Car keys with transponder chips require a special reprogramming to function. While any hardware store can cut a new key for you, the real challenge is making it function to work with the specific car you own. The key you reprogrammed needs to be matched with the specific identification number of the vehicle, or it won't start the engine.
Transponder chips, which are used to stop theft of cars are a standard feature of modern automobiles. The chip is a small microcircuit that emits a radio frequency signal when the ignition key is inserted. The car is able to detect the signal, and starts the engine only if it matches the original one that was programmed in the vehicle. The car is also programmed to stop when it detects an incorrect frequency. This makes it more difficult for thieves who are not experienced to wire a vehicle and start it.
The key and the chip are connected via a circuit board that includes an induction coil. When the key is put in the ignition the magnetic field is created around the transponder. This generates a signal that gets taken up by the coil, which sends it to the key's identification number. The ID number of the key is transmitted back to the vehicle and if it is in line with the engine will start.
There are a few different ways to program a transponder key however, they all require a special tool. These tools can be purchased online or from most automotive locksmiths. They're not cheap, but they're crucial for programming the chip into your car.

In this scenario, you'll need to make sure that the key has not been damaged or that the transponder has been altered in any way. To accomplish this, you'll need a scanner or a computer equipped with an USB port to scan the chip and determine its identity.
Reprogramming a transponder key is quite simple, but it requires special software and a scanning tool. It's best to ask an auto locksmith for help if you're a novice. Avoid buying used keys as they might already be programmed, and they won't be compatible with your vehicle.
