How to program a key
Prior to the beginning of the 21st century, most cars used basic key systems. The keys were made of metal and featured grooves that match the internal components of the ignition cylinder. As time went on and technology advanced, more and more automobile manufacturers began blending physical and electronic protocols to prevent theft. Key systems, also known as transponder keys or chips keys are designed to make it difficult for thieves to steal the vehicle.
The key chips inside the keys have a specific serial number that transmits a signal to the receiver inside of your car. When the signal is received, it compares it to the code that is stored in the car's computer. If the codes are similar then your car will start. If not, it won't start at all. This is why you should keep an extra car key, especially if your system is based on transponders.
You'll require special equipment to be able to program keys. You'll need to buy a blank key that matches the car's model and make. They can be bought at the dealership or through locksmiths, but you must make sure they're the right ones. If you attempt to use a key from an alternative model, it will not work.

The newest models also allow remote management and configuration and are cloud-based.
reprogram car key are equipped with keyless entry systems. The system works by emitting radio signals that are received by the keyfob. The signals are then compared to the correct code stored in the car's computer, and when everything is in order, the car will unlock. The car will not start when the signals aren't identical. If your key fob has not been already programmed, it is possible to follow a few steps to programme it.
You'll first need to be sure that all doors, except the driver's door are locked. You'll also need the original key fob, and any other accessories you'd like to program.

Transponder keys, sometimes referred to as chip keys, have a microchip built into the head of the key. The antenna ring transmits electromagnetic energy to the transponder whenever the key is inserted in the barrel of the ignition lock. The energy is absorbed by the chip and it transmits the radio frequency signal, which includes an identification code that corresponds with the unique digital serial number in the car's computer system. This helps prevent unauthorized attempts to start the car, as only the correct key will be able to do so.
It is believed that this technology will be more secure than traditional car keys because it makes it much more difficult for thieves to "hot wire" an automobile and get it started. It's not foolproof, and thieves have discovered ways to trick and defeat the system. So even cars equipped with transponder keys aren't safe from theft.

If the codes match, the car will start. If the codes don't match the car won't start or remain dead.
