How to program the key
Most cars had basic key systems up until the turn of 21st century. The keys themselves were metal and had grooves that corresponded to 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. automotive key programming , also known as transponder keys or chips keys, are designed to make it harder for thieves to steal an automobile.
The key chips that are in the keys have a specific serial number that sends signals to the receiver inside your car. When the signal is received it is compared to a code 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 an extra car key, especially if the system is based on transponders.
You'll require specialized equipment to learn how to program keys. You'll also require the blank key for your specific make and model. You can purchase them from a locksmith or a car dealership, but it's essential to purchase the correct keys. If you attempt to use a key that is from another model, then it will not work.

When the time has passed you can take off the key and see whether the security indicator on your dashboard was gone. If it didn't go out, you will need to repeat the process a third time.

The newest models also allow remote management and configuration, and are cloud-based.
Most 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. The signals are then compared against the correct code in the car's computer and if everything is in order the car will be able to unlock. If the signals do not match then the car won't start. There are a variety of steps you can take to program your new key fob, if it's not already programmed.

This should be left to a professional who can minimize the risk of data corrupting and ensure that your keys are programmed correctly.
Transponder Keys
Transponder keys, also referred to as chip keys, have a microchip built into the head of the key. When the key is inserted into the barrel of the ignition lock and then turned to ON, the antenna ring sends an electromagnetic energy blast through the transponder chip. The chip absorbs this energy, and then transmits a radio frequency signal that includes an identification code. This code matches the unique digital serial numbers of the computer system of the car. This will prevent any unauthorised attempts to start the car as only the correct key can start the car.
It is believed that this technology will be more secure than conventional car keys because it makes it harder for a thief to "hot wire" the vehicle and start it.

The keys have electronic chips inside them that communicate with the car's receiver via radio signals. The car's computer then compares this code on the key to the one in its database. If the codes match the car will begin. If the codes don't match the car won't start or remain dead. Luckily, most of these electronic keys can be programmed and replaced by an expert locksmith or an auto dealer using the appropriate equipment.
The procedure should be fairly simple if you are able to locate a key programmer that is cheap on the internet or in an auto parts store.
