In contrast to the central locking element remote key fob repair near me of a conventional key which is powered by batteries, a transponder chip is powered by an infrared (IR) signal transmitted by the antenna ring on the ignition cylinder.

The chip responds with an unique code to the immobiliser of your mobile car key repair (look at these guys). The car's computer compared the code stored in its memory with the one from the transponder chip and if they match the engine will begin to rev.
