Keys
Most modern cars require a transponder keys to operate. This gives security and protection against theft. The keys are programmed by a locksmith or an authorized dealer to work with the car's systems and the specific model. It is expensive to replace them if they're lost, so it's best to have spares in your possession. You can also find replacement keys fobs at various online stores and in many brick-and mortar auto shops. How can you know that the one you purchased is authentic? Are you able to tell whether the unit has been programmed to work with another vehicle, or if it can be programmed again?
If you want to program an entirely new key first, you need to make sure that your car is operating. Insert the key you want to reprogram into the ignition, but do not turn it. You will only have a couple of seconds before the car's system resets commands and then exits programming mode. This is why it is crucial to be quick and not pause between steps. To prevent this from happening, turn off the engine. You can test the car's security system by turning the key to the "on" position and back to the "off" position. There should be a chime indicating that the process was successful. The door locks will be able to cycle.
Certain newer vehicles have rolling key system, which prevents thieves from using a stolen vehicle's key to start it. This feature is still vulnerable to a technique dubbed a replay attack which allows thieves to record the signal of the vehicle's key fob, then reproduce it to open the car. To prevent this, manufacturers have added a security feature known as the CAN bus protocols to stop hacking.

Certain manufacturers have a unique encryption on their keys that cannot be decoded using a simple program. These types of vehicles require to be programmed by a professional, and you should only attempt this procedure only if you've worked with electronic devices. Consult sell or look up the website of the manufacturer to learn how to program it. The steps are different according to the type of vehicle.
Transponder chips
Transponder chip car keys require special reprogramming in order to work. Any hardware store can give you a new car key, but the real challenge lies in integrating it with your car. The key must be programmed to match the exact identification number on your vehicle, or else it won't start.
Transponder chips are a standard feature of modern cars and are designed to stop car theft. The chip is a microcircuit that transmits a radio-frequency signal when the ignition key is placed. The car can detect the signal and begins the engine only if it matches the one programmed into the vehicle. The vehicle is also programmed to shut down when it detects an incompatible frequency. This makes it more difficult for novice car thieves to hot wire a vehicle and then start it.
The key and the chip are linked by the circuit board which includes an induction coil. When the key is placed in the ignition, a magnetic field is generated around the transponder. This generates a signal that is taken up by the coil and then transmitted to the key's identification number. The ID number of the key is then sent back to the vehicle and if it matches, the engine will start.
There are a few different ways to program a transponder keys, however, all require an appropriate tool. You can buy these tools on the internet or at many locksmiths for cars. These tools are not expensive, but they are essential to program your car's chip.
You may also use a resettable key that was programmed for an alternative vehicle. In this instance, you must make sure the key hasn't been damaged or that the transponder isn't altered in any way. The chip can be read with a scanner, or a computer with an USB connector.
Reprogramming an transponder's key is easy, but it will require special software and a scanning tool. It's best to ask an auto locksmith for assistance if you're a novice. Avoid buying used keys as they could already be programmed and won't work with your vehicle.
