Before the turn of the 21st century the majority of cars utilized basic key systems. The keys were made of metal and had grooves to correspond to the internal parts in the ignition cylinder. As technology improved, more and more car manufacturers began to combine physical and electronic protocols to stop theft. These key systems are called transponder keys or chip keys, and are designed to make it more difficult for thieves to start the vehicle.

The key chips in the keys have a unique serial number that sends an electronic signal to the receiver inside your car. When the signal is received, it compares it to a code stored in the car's computer. If the codes are identical, your car will begin to start. If the codes don't match, your vehicle won't start at all. This is one of the main reasons why you should always keep a spare key in your car, especially in the case of an electronic transponder.

Begin by putting the new key in the ignition and turning it to "on". It is necessary to leave the new key in this position for about 10 minutes and 30 second. Once the time is up, you can remove the key and observe whether the security indicator on your dashboard went out. If it didn't then you'll need to repeat the process for the third time.
