How to Program a Car Key
Modern cars have more than just a key that can start the engine. They also have a remote control that allows you to lock or unlock doors. These key fobs need to be programmed correctly.
Some car keys can be preprogrammed by the owner himself, but it is recommended to consult an expert. This will help protect against any possible damage to the computer system and ensure that the new key is working properly.
How do you program the key
The majority of cars had basic keys systems prior to the turn of 21st century. Keys were made of metal and featured grooves that correspond with the internal parts in the ignition cylinder. As time went on and technology advanced, more and more automobile manufacturers began blending physical and electronic protocols to stop theft. These key systems, also known as transponder keys or chips keys, are designed to make it harder for thieves to open an automobile.
The key chips in the keys have a specific serial number that sends an electronic signal to the receiver in your car. When the signal is received, it compares it to the code that is stored in the car's computer. If the codes match, your car will begin to start. If not, it will not start at all. This is one of the main reasons you should keep a spare key in your vehicle, particularly if you have transponder-based systems.
If you're interested in learning how to program a key, you'll need some specific equipment. You'll also need the blank key for your specific make and model.

These professionals are equipped with the tools and equipment required to access the onboard diagnostics port in your car and make the switch.
Keyless Entry Systems

This lets you manage the system and monitor its activity from anywhere on the property, and it eliminates the need for keys or locks. The system is also able to detect and deactivate lost or stolen cards. The most recent models also permit remote management and configuration as well as are cloud-based.
Most modern cars are equipped with a keyless entry system. To enable this feature the car emits radio signals which are picked up by a particular key fob. The signals are then compared against the correct code in the car's computer and when everything is in order, the car will unlock. If the signals do not match then the car won't start. If your key fob has not been already programmed, it is possible to follow a series of steps to program it.

When the key is inserted into the ignition lock barrel and turned to the ON position the antenna ring emits a burst of electromagnetic energy through the transponder chip. The energy is absorbed by the chip, which then transmits an audio frequency signal that contains an identification code that matches with the unique serial number that is stored in the car's computer system. This is to prevent any attempts by anyone else to start the car as only the correct keys will be able.
It is believed that this technology will be more secure than traditional keys for cars because it makes it more difficult for thieves to "hot wire" an automobile and get it started. However, it's not foolproof and thieves have discovered ways to deceive and defy the system - so that even cars that have transponder keys aren't safe from theft.
You might be able to program a transponder key yourself when you have an instrument that works with your vehicle. The key programmer comes with a user guide that will guide you step-by-step through the process.

This is one of the reasons why it's a good idea to always have at least one spare key available.
The key fobs have electronic chips which communicate with the car's receiver using radio signals. The computer checks the key's code with the database. If the codes are the same, the car will start. If not, the car will not start or fail to start. Most of these electronic key can be programmed and replaced by an experienced locksmith or auto dealer with the proper equipment.
