This guide outlines common sizes and how to replace the battery safely.
Battery sizes and compatibility
Honda remotes from this era typically rely on small coin cells, with CR2032 being the default for most 2006 Accords. Some fob variants may use CR1616. If you’re unsure which one your car uses, inspect the battery you remove or consult the owner's manual or a dealership with your VIN to confirm.
Knowing the exact size helps you avoid buying the wrong battery and ensures proper contact and remote range once installed.
- CR2032 3V coin battery: the most common choice for 2006 Accord remotes.

In practice, CR2032 is the standard for most 2006 Accords, but CR1616 may appear in some variants. If you still have the original packaging or the old battery, that will confirm the correct size.
How to replace the battery
Before you replace, gather the appropriate battery and a few basic tools, and prepare a clean workspace to avoid losing small parts.
- Identify the correct battery size by inspecting the current battery or consulting the manual.
- Carefully pry the fob apart along the seam using a small flat tool or a coin; avoid forcing the case apart. Keep track of the order of the pieces.
- Remove the old battery and place it aside for recycling. Note the orientation of the battery (which side is facing up).
- Insert the new battery with the correct polarity, typically with the positive (+) side facing up toward the contacts inside the fob.
- Snap the fob halves back together and press firmly until you hear a click; test the remote to ensure all buttons work.
If the remote still doesn't function after replacement, recheck battery orientation, inspect the rubber buttons for dirt or damage, and consider replacing the fob's internal membrane or contacting a dealer for further assistance.

Dispose of used batteries properly at recycling centers. If you’re unsure which battery size your specific 2006 Honda Accord key uses, check the owner's manual or contact a local Honda dealer with your VIN. Battery life varies with use, but replacing every few years is common practice for maintaining reliable remote access.
