How do you program a key?
Before the turn of the 21st century, most cars used basic key systems. The keys were made of metal and incorporated grooves to match the internal components of the ignition cylinder. However, as time progressed and technology improved as it did, car manufacturers began blending physical and electronic protocols to stop theft. These key systems are referred to as transponder keys or chip keys and are designed to make it difficult for thieves to get into the vehicle.
The key chips inside the keys have a unique serial number, which transmits a signal to the receiver in your car. The signal is then compared to the car's computer when it is received. If the codes match, then the car will start. If the codes don't match, your car will not even start. This is one of the primary reasons why you should always keep a spare key in your car, especially when you use transponder-based systems.
If you're interested in learning how to program keys, you'll require some special equipment. You'll also require a blank key that matches your specific make and model.

Once the time is up you can take off the key and check whether the security indicator on your dashboard was gone. If not then you'll have to repeat the process for the third time.

They are equipped with the tools and equipment needed to access the onboard diagnostics port in your car and perform the switch.

The system is also able to detect and block stolen or lost cards. The newest models also allow remote management and configuration as well as are cloud-based.
Most modern cars are equipped with a keyless entry system. The system works by sending radio signals which are detected by an specialized keyfob. The signals are then compared with the correct code that is stored in the car's computer, and if everything is in order, the car will unlock. If the signals do not match, the car will not start. There are several steps you can follow to program your new key fob, if it's not already programmed.

Transponder Keys

When the key is placed in the barrel of the ignition lock and then turned to the ON position the antenna ring emits an electromagnetic energy blast through the transponder chip. This energy is absorbed by the chip and sends back an audio frequency signal that contains an identification code that is matched up to the unique digital serial number in the car's computer system. This will prevent any unauthorized attempts to start the car, as only the correct key can start the car.
This technology is thought to be more secure than a traditional car key since it makes it more difficult for thieves to "hot wire" the vehicle and start it.
