Transponder Chips
Transponder chips are in many newer cars to prevent car theft. These are small computer microchips that emit low-level radio signals. They have a unique serial number that authenticates the key to your vehicle when it is plugged into the ignition barrel. If your vehicle doesn't recognize the signal it will shut down. This technology has proven to be an immense success in stopping auto theft. This technology has also saved car owners a great amount of money as they do not have to replace their vehicles.

In the past, car thieves would force your car's ignition switch into the "on" position with a flat screwdriver or even use hot wires to disable the system altogether. These kinds of thefts have been drastically decreased with the introduction of the transponder chip.
When you insert a transponder keys into the ignition, it will transmit the signal which is received by a hidden antenna that is positioned around the barrel of the ignition. This antenna is programmed with the frequency of the chip within the key. The car's computer onboard will recognize that the key is genuine and allow the fuel to flow, then power the starter or start it.

There are also buttons that you can press to trigger features like trunk release, door locks or control of the fuel flap. Some fobs have additional functions that can be controlled with the push of a button for example, the "smart" key fob that allows you to bring your car into tight parking spots, like you would with a Tesla or Genesis GV60.
You can program some replacement key fobs yourself using the help from a user guide, but you'll need to call an automotive locksmith in the event that yours isn't functioning.

The majority of key fobs are equipped with security features to make it harder for attackers replicate and clone the signals that they transmit. Certain key fobs come with pseudo-random code generators which generate a new unlock code each time you press the button.

In some instances you can purchase a replacement keyfob from an auto dealer or other retailer. Your automotive locksmith will then program it to work with your car. This is because the majority of major US and Asian auto manufacturers have key-fob programming protocols with third-party companies that produce the tools used by auto locksmiths to program their customer's keys.

Instead, they recommend purchasing fobs specifically designed for your vehicle, so that you can be certain they'll function correctly and are less prone to issues such as interfering or incompatibility. This will save you money over the long term by avoiding costly repairs or replacing your fobs.
