How to Program a Car Key
Modern cars come with more than just a key which can start the engine. They also come with a remote control that can lock or open doors. These key fobs must be programmed in order to function.
Some keys for cars can be preprogrammed by the owner themselves but it's best to consult with an expert. This will prevent any damage to the computer system of the car and will ensure that the key is working correctly.
How do you program the key
Most cars had basic key systems until the turn of the 21st century. Keys were made from metal and incorporated grooves to match the internal components in the ignition cylinder. As technology improved, more and more car makers began to mix electronic and physical protocols to stop theft. These key systems are referred to as transponder keys or chip keys and they're designed to make it harder for thieves to start the vehicle.
The key chips inside the keys have a unique serial number that transmits signals to the receiver in your car. The signal is then compared to an identifier in the car's computer when it is received. If the codes are compatible, then your car will start. If the codes don't match, your car will not even start. This is the reason you should keep an extra car key especially if the system is transponder-based.
You'll require special equipment to learn to program keys. You'll need to buy a blank key that matches your car model and make. You can purchase these at an auto locksmith or a locksmith dealership, but it's important to buy the right one. If you use a key that is for another model, it won't function.
Start by inserting the new key in the ignition and turning it to "on". You'll need to leave the key in this position for about 10 minutes and 30 seconds. When the time has passed you can take off the key and see if the security light on your dashboard went out. If it didn't, you will need to repeat the process a third time.

These signals are then compared with the correct code in the car's computer and when everything is in order the car will be able to unlock. If the signals don't match and the car does not start. There are a variety of steps you can follow to program your new key fob, if it's not programmed yet.

Transponder Keys

When the key is inserted into the ignition lock barrel and turned into the ON position the antenna ring transmits a burst of electromagnetic energy through the transponder chip. The chip absorbs this energy and then transmits a radiofrequency signal that includes an identification code. The code is matched to the unique serial numbers that are stored in the computer system of the car. This helps prevent unauthorised attempts to start the car, because only a valid key will be able to start the car.
The technology is believed to be more secure than a conventional car key, as it makes it more difficult for thieves to "hot wire" the vehicle and start it. But it's not foolproof, and thieves have discovered ways to trick and defy the system - so that even vehicles with transponder keys aren't immune from theft.
