How do you program a key
Most cars had basic key systems prior to the turn of the 21st century. Keys were made of metal and had grooves to correspond to the internal parts of the ignition cylinder. As technology advanced, more and more car makers began to mix physical and electronic protocols to stop theft. Key systems like these, also known as transponder keys or chips keys are designed to make it more difficult for thieves to steal an automobile.
The key chips inside the keys have a specific serial number, which transmits signals to the receiver inside of your car. When the signal is received, it compares it to a code stored in the car's computer. If the codes match, your car will begin to start. If not, it won't start at all. This is why you should keep an extra car key particularly if your system is based on transponders.
You'll need special equipment to be able to program keys. You'll also need an uncut key for your particular make and model. You can buy them at an auto locksmith or a locksmith dealership, but it's important to buy the right one. If car key programming use a key from another model, it won't work.
To start the process, you need to insert the new key into the ignition and turn it to the "on" position. You'll need to keep the key in this position for about 10 minutes and 30 seconds. After the time has passed you can take off your key and see if the security indicator on your dashboard has gone off. If it didn't go out, you will need to repeat the procedure three times.

This allows you to control the system and monitor activity from anywhere on the property, and removes the need for locks or keys. The system is also able to detect and block stolen or lost cards. Additionally, the most recent models are cloud-based and allow for remote management and configuration.
The majority of modern cars are equipped with the keyless entry system. To accomplish this the car emits radio signals that are detected by a special key fob. These signals are then compared with the correct code in the car's computer, and when everything is in order the car will be able to unlock. The car will not start when the signals aren't identical. There are several steps you can follow to program your new key fob if it isn't already programmed.

For instance, you could be directed to insert your new key into the ignition with the doors shut, and then press a button on the key fob within a short time period. The car could then respond by adjusting the door locks or generating a chime to indicate that the key was successfully programmed.

This is a risky technique and can cause corruption of the data in 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 programmed correctly.
Transponder Keys
Transponder keys, sometimes referred to as chip keys, come with an embedded microchip 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 chip absorbs this energy, and then sends a radio frequency signal that includes an identification code. This code matches the unique digital serial numbers that are stored in the computer of the car. This prevents unauthorised attempts to start the car as only the correct key will be able to do so.
The technology is believed to be more secure than traditional keys for cars because it makes it much more difficult for thieves to "hot wire" the vehicle and start it. But it's not foolproof and thieves have discovered ways to evade and defeat the system - which means that even cars equipped with transponder keys are not immune from theft.
Depending on the make and model of your vehicle depending on the make and model of your car, you might be capable of programming a new transponder key yourself with a key programer that is compatible with the car you own. The key programmer should include an easy-to-follow guide to walk you through the process of programming your key.

This will save you time and money, and will keep your car's security system working exactly as it should. Plus, it's a lot safer than trying to do it yourself! If you choose the wrong key programmer or follow a guide that is not official and the data in your car's system can be corrupted and the new key won't function.
