How to Program a Key
Prior to the beginning of the 21st century most cars used basic key systems. Keys were made from metal and had grooves to correspond with the internal parts of the ignition cylinder. As time passed and technology advanced, more and more automobile manufacturers began to combine physical and electronic protocols to prevent theft. These key systems are referred to as transponder keys or chip keys and are designed to make it difficult for thieves to start the vehicle.
The key chips contain a unique serial code which transmits a signal to the receiver in your car. When the signal is received it compares it with the code that is stored in the car's computer. If the codes are similar then your car will start. If not, it will not start at all. This is one of the primary reasons why you should always keep a spare key on your vehicle, particularly in the case of transponder-based systems.
If you're interested in learning how to program keys, you'll need some special equipment. You'll need to buy a blank key that matches the car's model and make.

Start by inserting the new key into the ignition and turning it to "on". You'll need to keep the key in this position for around 10 minutes and 30 seconds. When the time has passed you can take off the key and check whether the security indicator on your dashboard was gone. If not then you'll have repeat the process the third time.

The system is also able to detect and deactivate lost or stolen cards. Additionally, the most recent models are cloud-based, allowing for remote management and configuration.
Most modern cars come equipped with the keyless entry system. The system works by sending radio signals which are received by a special keyfob. The signals are compared to the code that is stored in the computer of the car, and if all is in order, the car will unlock. If the signals do not match then the car won't start. There are several ways to program your new key fob if it's not already programmed.
First, you'll need ensure all the doors are locked except for the driver's side. You'll also need the original key fob, and any other accessories you want to program.

When the key is placed in the ignition lock barrel and then turned into the ON position, the antenna ring sends a burst of electromagnetic energy through the transponder chip. The chip absorbs the energy and then sends a radio frequency signal that contains an identification code. This code is in line with the unique digital serial numbers of the car's computers. This is to prevent unauthorized attempts to begin the car since only correct keys will be able.
This type of technology is thought to be more secure than the traditional car key because it makes it harder for a thief "hot wire" the vehicle and start it. However, it's not foolproof and thieves have discovered ways to evade and defy the system - so that even vehicles with transponder keys aren't safe from theft.
