Classic LoJack®: Replacing the Battery in the Early Warning Key Pass
Attention: If you purchased LoJack before May 2021, you are probably using the Classic LoJack System with Stolen Vehicle Recovery only. If you purchased LoJack after May 2021, you are probably using the New LoJack with Stolen Vehicle Recovery service + Connected Car features.
We recommend changing the battery in your Classic LoJack® Early Warning Key Pass every six months or every time you change the batteries in your home smoke detectors.
Please reference the directions below for more information.
