Utilizing special techniques, it is possible to copy a standard car key, but not the transponder key. Contrary to the remote central locking element of a conventional key, which is powered by batteries, a transponder chip is powered by the infrared (IR) signal transmitted by the antenna ring that is located on the ignition cylinder.
