The 2014 Camry key fob uses a 3-volt CR2032 coin cell. This is the standard battery inside most Camry remotes from that year. It’s a common size that you can buy at most supermarkets, drugstores, or auto parts stores.
In most markets, the CR2032 is the correct choice for the smart-key fob, though some regional variants or different fob designs may use a slightly different coin cell. If you’re unsure, check the old battery for the model code or consult your owner's manual.
Identifying the right battery
Before you buy a replacement, make sure you have the correct type and size. The key fob is designed for a compact, flat battery that sits on the inside face of the fob. Here are the main points to verify:
- Battery type: CR2032 3V lithium coin cell
- Shape and size: approximately 20 mm in diameter and 3.2 mm thick
- Availability: Widely stocked at electronics retailers, supermarkets, and auto parts stores
With the correct battery in hand, you’re ready to replace it and restore key fob function.
How to replace the battery
Follow these steps to replace the CR2032 in your 2014 Camry key fob. Use a clean, flat workspace and handle components gently to avoid shorting the circuit.
- Release the mechanical key (hidden key) by sliding the small latch on the back of the fob and pulling out the key blade.
- Use a small flat-head screwdriver or a thin coin to gently pry apart the two halves of the fob along the seam.
- Separate the halves enough to access the battery holder. Note the orientation of the old battery (plus side facing up).
- Carefully remove the old battery and dispose of it properly according to local regulations.
- Insert a new CR2032 with the plus (+) side facing up, ensuring it sits flat in the holder.
- Reassemble the fob halves, reinsert the mechanical key, and test the fob by pressing buttons to verify it’s functioning.
In most cases, replacing the battery does not require reprogramming or re-pairing the fob with the vehicle. If the fob still doesn’t work after replacement, recheck the battery orientation or consult a dealer.
Summary
The 2014 Toyota Camry key fob uses a CR2032 3V lithium coin cell. Replacement is straightforward: extract the old battery, insert a new CR2032 with the correct orientation, reassemble, and test. Batteries are affordable and widely available.
