Honda CR-V Key Fob Battery: Deluxe CR2032 3V
Most Honda CR-V smart key fobs use a single CR2032 3V lithium coin cell. Honda specifies a CR2032 for the 2024 CR-V remote, though older remote designs may take a CR1616 or CR1620 instead.

Will This Battery Work in Your CR-V Fob?
A CR-V model year alone does not tell you the battery type. Run this quick check before you buy.
Not every CR-V uses a CR2032. Honda’s 2006 and 2011 CR-V manuals list a CR1616, and some other remote designs use a CR1620. The Amazon listing also says this pack is not for standard Honda keys with the key blade sticking out of the fob.

CR-V Key Fob Battery Replacement Difficulty
This is an easy do-it-yourself job for a CR2032 smart remote. Honda’s documented procedure uses the built-in key and a small flat-tip screwdriver, with a cloth to prevent scratches, and it has no programming step. The hardest part is confirming that your remote really takes a CR2032. Tap a slice to highlight it.
- 25% Opening the fob case
- 20% Swapping the cell & polarity
- 40% Choosing the correct battery
- 15% Testing the fob
The difficulty score and effort split are an editorial estimate based on Honda’s documented steps, not an official Honda rating. Older remotes with a small case screw take a little more care.

Safety, Storage & Disposal
Honda warns that a swallowed remote battery can cause severe internal burns or death. Energizer says serious injury can happen in as little as two hours. Keep new and used cells away from children, and get emergency medical help immediately if you suspect ingestion.
- Never recharge, crush, open, short-circuit or burn it.
- Keep spare cells in their original pack and out of children’s reach.
- Keep used cells out of household trash and recycling bins.
- Tape terminals or bag each cell, then use a battery collection point.
Honda CR-V Key Fob Battery: FAQ
What battery does a Honda CR-V key fob use?
Honda lists a CR2032 for the 2024 CR-V remote. Other CR-V remote designs can use a CR1616 or CR1620, so check your owner’s manual or the code on the old battery.
Does the Deluxe CR2032 fit every Honda CR-V?
No. It fits remotes that call for a CR2032. The listing also says it is not for standard Honda keys with the key blade sticking out of the fob.
Do I install both batteries in the pack?
No. The pack holds two cells, and the documented CR-V remote takes one. Keep the second as a spare.
Is the CR2032 rechargeable?
No. A standard CR2032 is a single-use lithium/manganese dioxide coin cell and must never be recharged.
How long does a key fob battery last?
Honda says remote battery life is about two years, depending on how often you use the remote. This is a Honda estimate, not a Deluxe test result.
Do I need to reprogram the fob after a battery change?
Honda’s documented 2024 CR-V procedure has no programming step. If the fob still fails, check the battery type and polarity, then ask a dealer to inspect it.
How should I dispose of a used CR2032?
Do not put it in household trash or recycling bins. Tape the terminals or bag each cell individually and take it to a battery collection or hazardous-waste service, following your local rules. Keep used cells away from children.
