How to program the key
Prior to the beginning of the 21st century most cars used basic key systems. Keys were made of metal and featured grooves that correspond with the internal parts in the ignition cylinder. As technology advanced, more and more automobile manufacturers began to combine electronic and physical protocols in order to prevent theft. These key systems are called transponder keys or chip keys and are designed to make it more difficult for thieves to open the vehicle.
mobile car key programming contain unique serial codes which transmits a signal to the receiver inside your car. When the signal is received it is compared to a code stored in the car's computer. If the codes match, then your car will begin to start. If the codes aren't compatible, your car will not even start. This is why you should keep a spare car key, especially if your system is transponder-based.

The signals are then compared to the code stored in the computer of the car, and if all is in order, the car will unlock. The car won't start when the signals aren't identical. If your key fob isn't already programmed, you may follow a few steps to program it.

This energy is absorbed into the chip and it transmits an audio frequency signal that contains an identification code that matches with the unique serial number of the car's computer system. This is to prevent unauthorized attempts to begin the car as only the right keys can be used.
The technology is believed to be more secure than a traditional car key since it makes it difficult for thieves to "hot wire" the vehicle to start it.
