How do you program the key
The majority of cars had basic key systems until the turn of 21st century. The keys were made of metal and featured grooves that correspond with the internal parts in the ignition cylinder. As technology advanced, more and more automobile makers began to combine physical and electronic protocols in order to prevent theft. These key systems, also known as transponder keys or chips keys, are designed to make it difficult for thieves to start a vehicle.
The key chips in the keys have a specific serial number that transmits an electronic signal to the receiver in your car. When the signal is received, it compares it to the code that is stored in the car's computer. If the codes match, your car will start. If not, it won't start at all. car key programing is why you should keep an extra car key particularly if your system is transponder-based.
You'll need special equipment to learn to program keys. You'll need to buy a blank key that is compatible with the car's model and make. You can purchase them from the locksmith shop or at a car dealership, but it's important to purchase the correct keys. If you use a key for another model, it will not function.
To begin the process, simply insert the new key into the ignition and turn it to the "on" position. You'll need to keep the new key in this position for around 10 minutes and 30 seconds. After the time has expired you can take off the key and see whether the security indicator on your dashboard was gone. If it didn't, you'll need repeat the process the third time.

It is possible to monitor and control the system from anywhere within the property. Keys and locks are not required. The system is also able to detect and block stolen or lost cards. In addition, the newest models are cloud-based and allow for remote management and configuration.
The majority of modern cars are equipped with the keyless entry system. The system works by emitting radio signals which are picked up using an specialized keyfob. The signals are compared with the code that is stored in the car's computer, and if all is in order the car will start to unlock. The car will not start when the signals aren't the same. If your key fob has not been already programmed, it is possible to follow several steps to programme it.
The first step is to ensure that all doors are locked, with the exception of the driver's side. You'll need the original key fob and any other devices you wish to program.

Transponder Keys
Transponder keys, sometimes referred to as chip keys, come with a microchip embedded in 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 emits an electromagnetic energy blast through the transponder chip. This energy is absorbed into the chip, which then transmits a radio frequency signal with an identification code that is matched with the unique digital serial number of the car's computer system. This helps prevent an unauthorized attempt to start the car because only a valid key can do so.
This technology is thought to be more secure than a traditional car key, as it makes it more difficult for a thief "hot wire" the vehicle and start it. However, it's not foolproof and thieves have found ways to deceive and thwart the system so that even vehicles with transponder keys aren't safe from theft.

Key fobs are equipped with electronic chips that communicate via radio signals to the car's receiver. The car's computer then compares the key's code to the one in its database. If the codes match the car will begin. If the codes do not match, the car will not start or will remain dead. Most of these electronic key can be programmed and replaced by an experienced locksmith or auto dealer using the proper equipment.
