Step 1: Retrieve the Emergency Key

Your 2022 Honda Civic key fob has a hidden mechanical key. This is your first point of entry.

Locate the small release button or tab on the side or bottom of your key fob.
Press or slide this button/tab.
Pull out the metal emergency key. Set it aside in a safe place.

Removing the emergency key reveals a crucial slot for the next step.

Step 2: Carefully Open the Key Fob Casing

This is where your small flat-head screwdriver or pry tool comes in handy. Be gentle to avoid damaging the plastic.

Look into the slot where the emergency key was removed. You’ll see a small notch or seam.
Insert the tip of your flat-head screwdriver or pry tool into this notch.
Gently twist or pry the tool. You should hear a slight click as the two halves of the fob begin to separate.
Work your way around the seam if necessary, carefully separating the casing. The goal is to pop it open without excessive force.

Once open, you’ll see the internal components, including the circuit board and the battery.

Step 3: Remove the Old Battery

The battery is usually held in place by small clips or a snug fit.

Note the orientation of the battery (which side is facing up – usually the positive (+) side).
Using your small flat-head screwdriver or your fingernail, gently pry the old CR2032 battery out of its holder. Be careful not to touch the circuit board with your fingers, as oils can interfere with conductivity.

Give the fob a gentle squeeze around the edges to confirm everything is snug.

The moment of truth!

Walk over to your 2022 Honda Civic.
Press the lock and unlock buttons.

If everything went well, your Civic should respond immediately. If not, don’t panic. Check the battery orientation and ensure the casing is fully closed. Sometimes, a quick second attempt is all it takes.
