2014 Rav4 Key Battery Replacement

Most cars now come with smart keys for added security. These keys integrate the remote lock and unlock function, a panic button, and in some cases remote start or trunk release. The remote functions typically require a small lithium coin cell type battery. In this video, I had to replace the battery for a 2014 Toyota Rav4. Watch to see how it's done whether battery replacement solves the problem!
