How to program a Key

Before the turn of the 21st century, most cars used basic key systems. The keys themselves were metal with grooves that matched the internal parts of the ignition cylinder. As time passed and technology advanced and improved, automobile manufacturers began to combine physical and electronic protocols to protect against 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 contain an unique serial number that sends a message to the receiver in your car. The signal is compared with an identifier in the car's computer when it is received. If the codes are identical the car will begin to start. If not, it will not start at all. This is why you should keep an extra car mobile key programmer, especially if the system is transponder-based.

If you want to learn how to program keys, you'll need some special equipment. You'll need to buy an uncut key that matches the model and make of your car. These can be purchased at the dealership or through locksmiths but you must make sure they're the right ones. If you use a key that is for another model, it won't function.

The chip absorbs the energy and then transmits a radiofrequency signal that includes an identification code. This code is in line with the unique digital serial numbers in the computer of the car. This is to prevent unauthorized attempts to begin the car since only right keys can be used.

This type of technology is thought to be more secure than a traditional car key since it makes it more difficult for a thief "hot wire" the vehicle to start it.
