Some have buttons that activate the security system of the vehicle or unlock the trunk.

5. Transponder Keys
In contrast to mechanical keys, transponder keys are equipped with a chip inside them that transmits the radio frequency signal to the car whenever it is inserted into the ignition. The computer system in the vehicle analyzes the signal to determine whether the serial number is identical to the one on the key. If it does, the vehicle will let the key unlock the door and begin the engine. The concept behind this is to prevent car theft by making it harder to wire a car and start the engine.
In theory, this technology is effective but clever car thieves are always looking for ways to defeat this technology. Additionally, the chips in these types of keys are not as durable as people would like to believe. They can get wiped out quickly, which can cause the key to stop functioning at all.
