Some keys for cars can be programmed by the owner themselves but it's best to consult with an expert. This will help prevent any possible damage to the computer system, and also ensure that the new key is working correctly.
How do you program the key
The majority of cars had basic key systems prior to the turn of the 21st century. Keys themselves were metal and had grooves that matched the internal components of the ignition cylinder. As time went on and technology advanced, more and more automobile manufacturers began blending physical and electronic protocols to prevent theft. These key systems are referred to as transponder keys or chip keys and they're designed to make it difficult for thieves to get into the vehicle.
The key chips contain unique serial codes that transmits a message to the receiver inside your car. When the signal is received it compares it with an existing code in the car's computer. If the codes are identical, your car will start. If not, it won't start at all. This is one of the main reasons why you should always keep a spare key in your vehicle, particularly if you have an electronic transponder.

This prevents any attempts by anyone else to start the car since only correct keys will be able.
This type of technology is thought to be more secure than a traditional car key since it makes it harder for a thief "hot wire" the vehicle and start it.
