Car Key Fob Battery Replacement

Introduction

My Subaru's keyless entry buttons weren't working too well, so I decided to replace the battery within it.

This procedure is relatively simple, and the same basic principle can be applied to most other manufacturers' key fobs.

What you need

1. Step 1 Key Fob Battery

   

   • Unscrew the single Phillips screw on the back of the key fob using a #1 Phillips screwdriver.

   • The two black plastic pieces should separate, revealing the control module. Lift out the control module from the rest of the key.
