How to Program a Key

Before the turn of the 21st century the majority of cars utilized basic key systems. Keys were made from metal and incorporated grooves to correspond with the internal parts of the ignition cylinder. As time passed and technology improved as it did, car manufacturers began blending physical and electronic protocols to prevent theft. These key systems are referred to as transponder keys or chip keys and they're designed to make it more difficult for thieves to open the vehicle.

The key chips come with a unique serial code that sends a message to the receiver inside your car. The signal is then compared to an identifier in the computer of the car when it is received. If the codes match, then the car will start. If the codes aren't compatible, your car will not even start. This is the reason you should keep an extra car key especially if the system is transponder-based.

You'll require special equipment to learn how to program keys. You'll need a blank key that is compatible with the car's model and make. They can be bought at a dealership or by a locksmith, but you must make sure they're the correct ones. If you use a key from another model, it will not work.

Modern automobiles are equipped with keyless entry systems. The system works by sending radio signals which are picked up using a special keyfob. The signals are compared to the code stored in the car's computer and if everything is in order the car will start to unlock. The car will not start in the event that the signals are not the same. If your key fob isn't already programmed, you may follow several steps to programme it.

When the key is placed in the barrel of the ignition lock, and turned to ON, the antenna ring sends an energy burst through the transponder chip. This energy is absorbed by the chip and it transmits a radio frequency signal with an identification code that matches with the unique digital serial number that is stored in the car's computer system. This is to prevent unauthorised attempts to start the car as only the proper keys will be able to do so.

The technology is believed to be more secure than a traditional car key since it makes it more difficult for a criminal to "hot wire" the vehicle to start it. But it's not foolproof and thieves have discovered ways to deceive and defeat the system - so that even cars that have transponder keys aren't immune from theft.

Key fobs are equipped with electronic chips that transmit radio signals with the car's receiver. The computer in the car then compares the key's code to the one stored in its database. If the codes match the car starts. If the codes don't match, the car will not start or will remain dead.
