It is possible to duplicate a conventional key, but not a transponder one. Contrary to the remote central locking element of a standard key which is powered by batteries the transponder chip is powered by an infrared (IR) signal that is transmitted through the antenna ring on the ignition cylinder.

To activate the transponder the ignition cylinder must be in the ON position. The ring emits IR energy that is picked up by a microchip inside the key. The chip then responds with a unique code to the immobiliser inside your car. The computer in the car examines the code in its memory to the transponder's and when the two codes match, it will start the engine.
