Most cars had basic key systems until the turn of the 21st century. The keys themselves were metal with grooves that were connected to the internal parts of the ignition cylinder. As technology advanced the number of car makers began to combine physical and electronic protocols to stop theft. These key systems are called transponder key programming keys or chip keys, and they're designed to make it difficult for thieves to start the vehicle.

The key chips in the keys have a specific serial number that transmits signals to the receiver inside of your car. When the signal is received it is compared to a code stored in the mobile car key programmer's computer. If the codes match then your car will begin. If not, it won't start at all. This is why it is important to keep a spare car key, particularly if your system is based on transponders.

If you're looking to learn how to program keys, you'll require certain equipment. You'll also need to purchase an uncut key for your particular model and make.

This helps prevent an unauthorized attempt to start the car, because only a valid key will be able to do so.
