How to Program a Key

Up until the turn of the 21st century, the majority of cars had basic key systems. Keys were made of metal and had grooves to match the internal components in the ignition cylinder. As technology advanced, more and more automobile manufacturers began to combine electronic and physical protocols to avoid theft. These key systems also known as transponder keys or chips keys, are designed to make it harder for thieves to start a vehicle.

The key chips come with a unique serial code that sends a message to the receiver inside your car. When the signal is received it compares it with an existing code in the car's computer. If the codes are identical then your car will begin to start. If not, it won't start at all. This is one of the main reasons to keep a spare key on your car, especially in the case of a transponder-based system.

You'll require special equipment to learn how to program keys. You'll need to buy an uncut key that matches your car model and make.

After the time is up, you can remove your key and see if the security indicator on your dashboard has gone out. If it didn't you'll have to repeat the procedure a third time.

This prevents any attempts by anyone else to start the car, as only correct keys will be able.

It is believed that this technology will be more secure than conventional car keys because it makes it much difficult for thieves to "hot wire" a vehicle and start it.
