Keys
Most 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 particular vehicle and its systems by an authorized locksmith or dealer. They are expensive to replace in the event of loss, so it is recommended to keep spare keys in the car. You can find replacement key fobs in online stores as well as many brick-and mortar auto shops. How do you ensure that the new one you have bought is genuine? Are you able to tell if the unit has been programmed to work with another vehicle, or if it can be reprogrammed?
To program a new car key you must first ensure that your vehicle is operating. Insert the key you want to reprogram into the ignition, but do not turn it. There are only a few seconds left before the system will reset all commands and exits the programming mode. This is why it is important to move fast and not pause between steps. Shut off the engine to stop this. You can test the car's security system by turning the key to the "on" position and then back to the "off" position. The door locks should cycle and you'll hear a sound that indicates that the process has been successful.
Certain newer vehicles have rolling key technology, which keeps thieves from using a stolen vehicle's key to open it. The feature is still vulnerable to a technique called a replay attack. It allows thieves to record and reproduce the signal received from the vehicle key fob to open the car. To stop this, manufacturers have 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 an ordinary program. You should only try this process if your experience is in electronic devices. Refer to the manual for your car or visit the manufacturer's website to find out how to program it. The steps will vary depending on the model of vehicle.
Transponder chips
Transponder chip car keys require special reprogramming in order to work. Any hardware store can make you a new car key but the real challenge lies in integrating it with your car. The key needs to be programmed to match the exact identification number on your car, otherwise it won't be able to start.
Transponder chips are a typical feature in modern cars and are designed to stop car theft. The chip is a microcircuit which emits a radio frequency signal when the key is placed in the ignition. The car detects the signal and starts the engine only if the signal matches the original that was programmed into the vehicle. The car is also programmed so that it will shut down when it detects an incorrect frequency. This makes it more difficult for novice car thieves to connect a vehicle with hot wires and then start it.
A circuit board with an induction coil that connects the chip to the key. When the key is placed in the ignition the magnetic field is generated around the transponder. This produces a signal which is taken up by the coil, which sends it to the key's identification number. automotive key programming is returned to the car, and the engine starts when the identification number is in line with.
There are several ways to program a key transponder, however all of them require an instrument that is specifically designed for. These tools can be bought on the internet or at most auto locksmiths. These tools are not expensive, but they are essential to program your car's chip.

In this instance, you must make sure the key has not been damaged or that the transponder isn't altered in any way. To do this, you'll need scanners or computers with an USB port to scan the chip and determine its identity.
Reprogramming an transponder is a simple process, but requires special software. It also requires the use of a scanner. It's best to ask an auto locksmith for help in case you're not an expert. Don't buy used keys since they could already be programmed and won't work with your car.
