If the codes match, your car will begin to start. If the codes aren't compatible, your car will not even start. This is the reason you should keep an extra car key especially if the system is transponder-based.

The majority of modern cars are equipped with a keyless entry system. This system works by emitting radio signals which are detected by an specialized keyfob. These signals are then compared with the correct code stored in the car's system, and when everything is in order the car will be able to unlock. If the signals do not match, the car will not start. If your key fob has not been already programmed, it is possible to follow a series of steps to program it.

This energy is absorbed into the chip, which then transmits the radio frequency signal, which includes an identification code that corresponds with the unique digital serial number of the car's computer system. This stops any attempts by anyone else to start the car as only the right keys can be used.
This type of technology is thought to be more secure than a traditional car key because it makes it harder for thieves to "hot wire" the vehicle to start it.
