Hey everyone, BMWs from approximately model year 2000 onward have keys without replaceable batteries. These keys are charged by the ring antenna in the ignition when you drive the vehicle. If you have more than one of these keys, it is recommended that you use each key at least once every 6 months for an extended driving period in order to maintain a battery charge in the key.
