Step-by-Step Guide to Replacing Your 2010 Honda CRV Key Fob Battery
Replacing the battery in your 2010 Honda CRV key fob is a simple process. Here’s how to do it:
-
Locate the small Phillips head screw: On the back of your key fob, you’ll find a tiny screw. This is what holds the two halves of the key fob casing together.
-
Unscrew and open the key fob: Use a mini-Phillips screwdriver to carefully remove the screw. Be patient, as the screw can be tight. The original author mentioned it might be secured with threadlocker. If it’s very tight, use a pair of pliers to get a better grip on the screwdriver for initial turning force, while pressing down firmly to avoid stripping the screw head. Working on a soft surface like a terrycloth towel can prevent scratches to your key fob.
-
Separate the key fob halves: Once the screw is removed, the key fob casing should split open into two halves.
-
Open the inner cassette: Inside the key fob, you’ll see a black plastic cassette containing the electronics and the battery. This cassette also splits into two halves. Gently pry it open.
-
Remove the old battery: You’ll now see the old CR1616 battery. Take note of the orientation – the positive (+) side with the writing should be facing down (not visible when installed). Carefully remove the old battery.
-
Install the new battery: Take your new CR1616 battery. Use a cloth or wear gloves to avoid touching the flat surfaces of the battery with your fingers, as this can reduce battery life. Press the new battery into place, ensuring the positive (+) side (writing facing down) is in the same orientation as the old battery.
-
Reassemble the cassette and key fob: Snap the two halves of the inner cassette back together, then close the two halves of the key fob casing.
-
Replace the screw: Reinsert and tighten the small Phillips head screw. Don’t overtighten.
