How do you program a key?

Most cars had basic key systems until the turn of 21st century. Keys were made of metal and featured grooves that correspond to the internal parts in the ignition cylinder. As technology improved, more and more automobile manufacturers began to combine electronic and physical protocols in order to prevent theft. These key systems are called transponder keys or chip keys and they're designed to make it harder for thieves to open the vehicle.

The key chips that are in the keys have a unique serial number, which transmits signals to the receiver inside of 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 the car will begin to start. If not, it will not start at all. This is one of the primary reasons why you should always keep a spare key in your vehicle, particularly if you have transponder-based systems.

These professionals are equipped with the tools and equipment needed to connect to the onboard diagnostic port on your car and perform the change.

Keyless Entry Systems

Keyless entry systems permit property access without the need for a physical credential. Security is provided by a combination between sensors and an onboard computing device.

There are a variety of steps you can take to program your new key fob, if it isn't already programmed.

Transponder Keys

Transponder keys, also known as chip keys, have a microchip embedded in the head of the key. When the key is inserted into the ignition lock barrel and turned to the ON position the antenna ring transmits a burst of electromagnetic energy through the transponder chip. This energy is absorbed into the chip and it transmits the radio frequency signal, which includes an identification code that is matched with the unique serial number in the car's computer system. This stops unauthorized attempts to begin the car, as 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 difficult for a criminal to "hot wire" the vehicle and start it.
