The 2016 Honda Civic key fob uses a CR2032 3-volt lithium coin cell. This is the standard battery type for most Civic remotes from that era and is easily available at electronics and automotive stores.
Understanding the battery and its compatibility
Honda’s 2016 Civic key fob generally relies on a single CR2032 battery across its trim lines. The battery fits into a small compartment in the back of the fob and is designed for quick, once-in-a-while replacement. If you aren’t sure which battery your specific fob requires, you can confirm by opening the fob and checking the battery type printed on the battery or the compartment label.
Fob design and function
The four-button remote used with most 2016 Civics provides lock, unlock, trunk release, and panic functions. Replacing the battery is a routine maintenance task and does not typically require reprogramming of the fob once the new battery is in place.
Replacing the battery
To replace the battery, you’ll need a CR2032 3V coin cell and a small tool to open the fob. Below are the steps to complete the replacement.
- Buy a fresh CR2032 battery from a reputable retailer or auto parts store.
- Turn the fob face down and locate the seam along the case. Use a small flathead screwdriver or a coin to gently pry apart the two halves of the fob.
- Carefully remove the old battery, noting which side was facing up (the plus side is typically marked on the battery).
- Insert the new CR2032 with the correct orientation (plus side facing up, as indicated inside the fob or on the battery labeling).
- Snap the fob halves back together and test all buttons to ensure proper operation. If any button doesn’t respond, reopen and reseat the battery.
The replacement process is quick, typically taking just a few minutes. When disposing of the old battery, do so at an appropriate recycling facility or store that accepts lithium batteries.
Where to buy and quick tips
CR2032 batteries are widely available at automotive retailers, big-box stores, pharmacies, and online. If you’re unsure, bring your fob to the store to confirm the battery size before buying. Keep a spare battery on hand to avoid downtime if the fob’s battery runs low in the future.
Summary
For a 2016 Honda Civic key fob, the standard battery is a CR2032 3V lithium coin cell. Replacement is straightforward: pry open the fob, swap in a new CR2032 with the correct orientation, reassemble, and test. Batteries are inexpensive and widely available, and no special programming is typically required after replacement.
