How to Program a Car Key
Modern cars have more than just a key to start the engine, they also include a remote to lock and unlock doors. These key fobs have to be programmed to function.

How do you program the key
Most cars had basic key systems prior to the turn of the 21st century. The keys were made of metal and incorporated grooves to correspond with the internal parts of the ignition cylinder. As technology improved, more and more car makers began to combine physical and electronic protocols in order to prevent theft. Key systems like these, also known as transponder keys or chips keys are designed to make it harder for thieves to steal a vehicle.
The key chips that are in the keys have a specific serial number, which transmits a signal to the receiver in your car. When the signal is received, it compares it to an existing code in the car's computer. If the codes match, 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 to keep a spare key in your vehicle, particularly when you use transponder-based systems.
If you want to learn how to program a key, you'll need certain equipment. You'll need to buy a blank key that is compatible with the car's model and make. They can be bought at a dealership or by a locksmith however, you must be sure they're the correct ones. If you use a key that is for another model, it will not function.
Start by inserting the new key into the ignition and turning it to "on". It is necessary to keep the key in this position for approximately 10 minutes and 30 seconds. After the time has expired you can take out the key and observe if the security light on your dashboard went out. If it didn't, you'll need to repeat the process for a third time.

These professionals have the tools and equipment needed to access the onboard diagnostic port on your vehicle and make the switch.

The system can also detect stolen or lost cards and then deactivate them. Additionally, the most recent models are cloud-based and allow for remote management and configuration.
Modern cars are equipped with keyless entry systems. To accomplish this the car emits radio signals which are picked up by a particular key fob. These signals are then compared against the correct code stored in the car's system, and when everything is in order the car will be able to unlock. The car won't start if the signals are not the same. If your key fob is not already programmed, it is possible to follow a series of steps to program it.
The first step is to ensure that all doors are locked, with the exception of the driver's side. You'll need to have the original key fob and any other devices you wish to program.

Transponder Keys
Transponder keys, sometimes referred to as chip keys, have a microchip embedded in the head of the key. The antenna ring transmits electromagnetic energy to the transponder whenever the key is inserted into the ignition lock barrel. The energy is absorbed by the chip, which then transmits the radio frequency signal, which includes an identification code that is matched with the unique digital serial number of the car's computer system. This is to prevent unauthorised attempts to start the car since only proper keys will be able to do so.
It is believed that this technology will be more secure than conventional car keys because it makes it more difficult for thieves to "hot wire" a vehicle and start it. But it's not foolproof and thieves have discovered ways to deceive and thwart the system so that even vehicles with transponder keys aren't protected from theft.

The key fobs have electronic chips inside them which communicate with the car's receiver via radio signals. The car's computer then compares this code on the key to the one stored in its database. If the codes are the same, the car will start. If not, the vehicle will be dead or refuses to start. Luckily, most of these electronic keys can be programmed and replaced by an experienced auto dealer or a locksmith using the appropriate equipment.
