Replace Honda Key Battery

1. Determine Your Battery Type:

Flip over your keyless entry remote and look for the battery type written on the back. If the battery type is illegible, don’t worry. Once you open the fob, the battery type will be written on the existing battery.

2. Open your Honda Key Fob:

If your keyless entry remote has a screw, remove it using a jeweler’s screwdriver. Separate the two halves of your remote using a small flathead screwdriver. Exert gentle pressure to avoid damaging the key.

3. Remove the Dead Battery:

Note the position of the positive and negative sides of the battery in the remote when you remove it. This will ensure you install your new battery properly. Be careful not to touch the battery terminals with your fingers. The oils in your skin can corrode the terminals and result in a shorten the life of your remote.

4. Insert the New Battery:

The new battery should go in the same position as the old. If you’re unsure, look for the positive (+) and negative (-) marks inside your keyless entry fob.

5. Reconnect the Two Halves of Your Honda Keyless Entry Remote:

Align the two halves of the fob and apply gentle pressure until you hear the remote snap together.

Test your remote to ensure it’s working properly. If you’ve purchased multiple batteries, leave the remaining batteries in the packaging and tape them inside your glovebox. Do not apply tape directly to the battery, the adhesive will effect its conductivity.
