How to Program a Car Key

The majority of cars had basic keys systems prior to the turn of 21st century. Keys themselves were metal and had grooves that matched the internal components of the ignition cylinder. However, as time progressed and technology advanced and improved, automobile manufacturers began to combine electronic and physical protocols to prevent theft. These key systems are called transponder keys or chip keys and they're designed to make it more difficult for thieves to open the vehicle.

The key chips in the keys have a unique serial number that transmits an electronic signal to the receiver inside your car. The signal is compared to a code in the computer of the car when it is received. If the codes match, then your car will start. If not, it won't start at all. This is why it is important to keep a spare car key, especially if your system is based on transponders.

The energy is absorbed by the chip, which then transmits a radio frequency signal with an identification code that corresponds with the unique digital serial number that is stored in the car's computer system. This prevents unauthorized attempts to start the car as only the correct key can do so.

The technology is believed to be more secure than traditional keys for cars because it makes it much more difficult for thieves to "hot wire" an automobile and start it.
