The 2014 Honda CR-V key fob uses a CR2032 3-volt lithium coin battery.
This article explains the battery type, how to identify the correct size, and the steps to replace it, along with tips for ensuring long-term reliability of the remote.
Battery type and compatibility
For the 2014 CR-V, the most common battery is the CR2032, a 3V lithium coin cell. It fits the standard remote key design used on most market versions of this model year. In rare regional variants, the battery size can differ, so it’s wise to confirm by inspecting the fob’s current battery or consulting the owner's manual.
Common battery sizes to know
Identify which sizes you might encounter in CR-V key fobs from this era before replacing. The sizes listed below cover the most likely possibilities:
- CR2032 — 3V lithium coin battery (the standard choice for the 2014 CR-V key fob).
- CR2025 — 3V lithium coin battery (a thinner variant used in some regional remotes).
- CR1616 — 3V lithium coin battery (rarely used in Honda CR-V remotes).
When in doubt, check the battery itself for the size marked on it and verify against the owner’s manual or retailer guidance.
Replacing the battery
Here are the typical steps to replace the CR2032 battery in a 2014 Honda CR-V key fob. The exact shape of the fob can vary by market, but the method is broadly the same.
- Gather a new CR2032 battery and a small flat tool or coin for prying open the case.
- Remove the mechanical emergency key by sliding the release latch on the fob and pulling the key blade out.
- Open the fob by gently prying along the seam with the flat tool to separate the two halves. Work slowly to avoid damaging the casing.
- Remove the old battery, noting the orientation (plus side facing up in most remotes).
- Insert the new CR2032 with the correct orientation, ensuring it sits flat and makes good contact with the terminals.
- Reassemble the fob, reinsert the emergency key, and test the buttons to confirm the remote functions (lock, unlock, trunk release, and panic, if present).
After replacing the battery, test the fob from a short distance to confirm reliable operation. If the remote still does not respond, inspect for corrosion on the battery contacts or consider having the fob serviced or reprogrammed at a dealership or qualified locksmith.
Tips and additional information
Additional guidance to keep the key fob working smoothly:
- Avoid exposing the fob to magnets or extreme heat, which can affect battery performance.
- Keep a spare CR2032 on hand for future replacements, ideally stored in a protective case.
- If the key has a built-in trunk button and the car does not respond, try replacing the battery and re-testing. If issues persist, a professional re-sync or replacement may be needed.
In some cases, the car’s system may require a re-sync after a battery replacement, especially if the remote has not communicated with the vehicle for a period of time. Consult the owner's manual or a Honda dealer if the fob remains unresponsive after a swap.
Summary
In short, a 2014 Honda CR-V key fob typically takes a CR2032 3V lithium coin battery. Replacing it involves prying open the fob, swapping in the new battery with correct polarity, and reassembling. If performance doesn’t improve after the swap, check the contacts for corrosion or seek professional assistance to re-sync or replace the fob.
