Transponder chips do not require the use of batteries to operate, a tiny copper coil contained in the chip is used as an antenna to induce a voltage from the magnetic field emitted from an antenna around the vehicles ignition.

Upon starting your car the vehicles antenna reads the code embedded on the transponder chip located the head of the key. If the code on the transponder chip matches the code stored in the vehicles engine or immobiliser ECU the vehicle will start. If the code doesn’t match the vehicle will not run.
