How to Program a Car Key Modern cars have more than a key that will start the engine. They also have a remote control which can be used to lock or unlock doors. Key fobs have to be programmed to work properly. Certain keys for cars can be preprogrammed by the owner themselves but it's best to consult with a professional. This will avoid any damage to the computer system of the vehicle and ensure that the key functions properly. How do you program the key The majority of cars had basic keys systems up until the turn of the 21st century. The keys were made of metal and featured grooves that match the internal components in the ignition cylinder. As time passed and technology improved, more and more automobile manufacturers began blending physical and electronic protocols to stop theft. These key systems are referred to as transponder keys or chip keys, and are designed to make it harder for thieves to start the vehicle. The key chips inside the keys have a specific serial number that transmits a signal to the receiver inside your car. The signal is compared with a code in the computer of the car when it is received. If the codes match, your car will begin to start. If the codes don't match, then your vehicle won't start at all. This is why you should keep an extra car key, especially if your system is transponder-based. If you want to learn how to program keys, you'll require some special equipment.

Most modern cars come equipped with the keyless entry system. To enable this feature the car emits radio signals that are picked up by a special key fob.

This stops any attempts by anyone else to start the car as only the correct keys will be able. This technology is believed to be more secure than conventional car keys because it makes it much more difficult for thieves to “hot wire” the vehicle and start it.
