How to program a key
The majority of cars had basic keys systems prior to the turn of the 21st century. The keys themselves were just metal and featured grooves that were connected to the internal components of the ignition cylinder. As technology advanced, more and more car manufacturers began to combine physical and electronic protocols in order to prevent theft. These key systems are known as transponder keys or chip keys, and they're designed to make it harder for thieves to start the 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 is compared to the code that is stored in the car's computer. If the codes match, the car will start. If the codes aren't compatible, your vehicle won't start at all. This is why it is important to keep a spare car key, especially if the system is transponder-based.

They will have the tools and equipment to connect to the onboard diagnostic port of your car and make the change.
Keyless Entry Systems
Keyless entry systems allow property access without requiring an actual credential. Security is offered by the combination of sensors and an onboard computing device. This lets you control the system and monitor activities from any place on the property, and it does away with the requirement for locks or keys. The system can also identify and deactivate lost or stolen cards. The newest models also allow remote management and configuration and are cloud-based.
Most modern cars come equipped with a keyless entry system. The system works by emitting radio signals that are detected by the keyfob. These signals are then compared against the correct code that is stored in the car's computer, and when everything is in order the car will be able to unlock. The car won't start when the signals aren't identical. There are several steps you can take to program your new key fob if it's not already programmed.

The car could respond by turning off the door locks or emitting an audible chime, which is a sign that the key has been successfully programmed.

But this is an extremely risky procedure and comes with the possibility of destroying the data on your car's computer. This should be left to a professional, who can minimize the risk of data corruption and ensure that your keys are correctly programmed.
Transponder Keys
Transponder keys are also referred to as chip key. They are equipped with a microchip embedded in the head of the keys. When the key is inserted into the ignition lock barrel and then turned to 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 which contains an identification number. This code matches the unique digital serial numbers in the computer of the car. This stops any attempts by anyone else to start the car as only the correct keys will be able.
This type of technology is thought to be more secure than the traditional car key, as it makes it harder for thieves to "hot wire" the vehicle to start it. But it's not foolproof and thieves have found ways to evade and defeat the system - which means that even cars equipped that have transponder keys aren't safe from theft.
Based on the make and model of your car You may be in a position to program a brand new transponder by yourself by using a key programming device that's compatible with the car you own.

Fortunately, many modern car manufacturers have improved their key systems to be more secure to reduce vehicle thefts. The key system was designed in a way to avoid hot-wiring which is the practice of using a key from a different vehicle to start the engine of your vehicle. To ensure that this method works you'll need at least two key fobs that are functioning for your vehicle. This is one of the main reasons why it's a good idea to always have at least one spare key available.
The key fobs have electronic chips inside them which communicate with the car's radio via radio signals. The computer compares the key's code with the database. If the codes are the same the car will begin. If not, the vehicle will be dead or refuses to start. Fortunately, the majority of electronic keys can be repaired and programmed by an expert locksmith or an auto dealer equipped with the proper equipment.
If you can find a low-cost car key programer on the internet or at an auto parts store, the procedure should be fairly straightforward.

You'll need to repeat this a certain number of times within a specified time frame for your vehicle to enter programming mode. This is indicated by the door locks turning or an audible chime.
Some modern vehicles are programmable with a tool connected to the onboard diagnostic port or EEPROM programming. Unfortunately, the majority of these tools are extremely expensive, and therefore unattainable for most car owners.
