How to program a Key
Prior to the beginning of the 21st century, the majority of cars had basic key systems. The keys themselves were metal with grooves that were connected to the internal components of the ignition cylinder. However, as time progressed and technology advanced as it did, car manufacturers began blending electronic and physical protocols to prevent theft. These key systems are called transponder keys or chip keys, and they're designed to make it harder for thieves to get into the vehicle.
The key chips have a unique serial code that transmits a message to the receiver inside your car. The signal is compared to a code in the car's computer when it is received. If the codes are compatible, then the car will start. If the codes don't match, your car will not even start. This is one of the main reasons you should keep a spare key on your vehicle, particularly if you have transponder-based systems.
You'll require specialized equipment to learn to program keys. You'll also need a blank key for your specific make and model. They can be bought at a dealership or by a locksmith but you must make sure that they are the correct ones. If you use a key for another model, it will not work.

The system is also able to detect and disable stolen or lost cards. The newest models also allow remote management and configuration and are cloud-based.
Modern automobiles are equipped with keyless entry systems. This system works by emitting radio signals that are detected by the keyfob. The signals are then compared to the correct code that is stored in the car's computer and when everything is in order the car will be able to unlock.

This will prevent any an unauthorized attempt to start the car since only the right key can perform the task.
The technology is believed to be more secure than traditional keys for cars because it makes it much difficult for thieves to "hot wire" the vehicle and get it started.
