Keys

Most modern cars require a transponder key in order to operate. This provides security and anti-theft protection. These keys must be programmed to your particular vehicle and its features by an authorized locksmith or dealer. It's expensive to replace them if they are lost, so it's best to keep extras on hand. You can find replacement key fobs in online stores, as well as many brick and mortar auto shops. How can you ensure that the key you purchased is authentic? Can you tell whether the unit is programmed to work with another vehicle, or if it can be reprogrammed?

To program a new car key first make sure that your vehicle is running. Insert the key you wish to program into the ignition, but do not turn it. You only have a few seconds before the car's system resets commands and leaves programming mode. It is essential to move quickly and do not be patient between each step. Shut off the engine to stop this. You can test the car's security system by turning the key to the "on" position and back to the "off" position. The door locks should cycle and you'll hear a chime signalling that the process has been successful.

Certain newer vehicles have rolling key system, which prevents thieves from using a stolen vehicle's key to open it. The technology is still susceptible to a technique known as replay attacks that allows thieves to record the signal from the key fob of the car and then replicate it to open the car. To combat this, manufacturers introduced security features known as the CAN bus protocols to prevent 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. These types of vehicles require programming by a professional.

Transponder chips

Car keys with transponder chips require a special reprogramming to work. Any hardware store can offer you a new car key however 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, or else it won't start.

Transponder chips are a typical feature of modern cars and are designed to prevent car theft. The chip is a microcircuit that transmits a radio frequency signals when the key is inserted into the ignition. The car then scans for the signal and then starts the engine in case it matches the original frequency that was programmed into the vehicle. The car will also shut down if a frequency is invalid. This makes it much harder for car thieves with no experience to wire a vehicle and then start it.

The key and the chip are connected by the circuit board which includes an induction coil. When the key is put in the ignition it creates a magnetic field created around the transponder. This produces a signal which gets taken up by the coil, which then transmits it to key's identification number. The key's ID number is sent back to the vehicle, and if it matches the engine will begin to run.
