How to Replace the Key Fob Battery on a Lexus HS

Model: Lexus HS Anf10 - Years 2009-2017
Part: Key

To replace the battery in the Lexus HS key fob, you only need a common tool: a flathead screwdriver that most people have at home or a similar tool. First, extract the key blade by pressing the appropriate button while pulling it out. Once done, use the screwdriver as a lever and apply slight pressure to separate the two halves of the key fob and open it. Replace the battery and close it back up. The battery required is a CR1632 button cell.
