How to program a key

Prior to the beginning of the 21st century most cars used basic key systems. The keys themselves were metal and featured grooves that were connected to the internal parts of the ignition cylinder. As time went on and technology advanced, more and more automobile manufacturers began blending electronic and physical protocols to protect against theft. These key systems also known as transponder keys or chips keys are designed to make it harder for thieves to open the vehicle.

The key chips come with a unique serial code which transmits a signal to the receiver inside your reprogramming car keys. When the signal is received it compares it with an existing code in the car's computer. If the codes are identical, your car will begin. If not, it won't start at all. This is the reason you should keep a spare car key, especially if the system is based on transponders.

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

This code matches the unique digital serial numbers that are stored in the computer system of the car. This prevents unauthorised attempts to start the car, as only right keys can be used.

The technology is believed to be more secure than traditional car keys because it makes it much harder for a thief to "hot wire" a vehicle and get it started. It's not foolproof, and thieves have discovered ways to evade detection and defeat the system. Therefore, even vehicles with a transponder keys aren't safe from theft.
