2014 Ford Focus Battery Size: Car vs. Key Fob
Find the U.S. 2014 Ford Focus gasoline-model battery specification and CR2032 key-fob size, plus opening methods and polarity instructions.
For the U.S. gasoline-model 2014 Ford Focus covered by Ford’s manual, the car battery is Group 96R. The factory key-fob battery is one CR2032 3-volt lithium coin cell. These are separate batteries with different jobs.
Ford’s U.S. owner’s manual lists Motorcraft BXT-96R-500/BXT-96R-590 for the 2.0L GDI and 2.0L GTDI EcoBoost engines on page 295, and CR2032 for the remote control on page 60. Ford’s 2014 Focus owner’s manual
If you mean the car’s battery
Use Group 96R as the starting point for the gasoline models covered by that manual, then have the seller confirm the application by VIN. AutoZone’s 2014 Focus battery guide also identifies Group 96R. Check the specified starting capacity, terminal layout and hold-down fit—not just whether a battery will fit in the tray.
Do not apply this gasoline-model specification to a Focus Electric or assume it covers every overseas-market Focus. Use that vehicle’s own manual and a VIN-based parts lookup.
If your problem is slow cranking or needing jump-starts, replacing the small battery inside the key fob is not a repair for the car’s starting-power supply. Have the vehicle battery tested before buying a replacement.
If you mean the key-fob battery
Buy one CR2032, 3V lithium coin cell for the factory remotes described in Ford’s manual. Before removing it, check the installed battery’s code and photograph its orientation. If an aftermarket replacement fob has a different marking, follow its own specification rather than forcing in a CR2032.
The opening method—and battery polarity—depends on the key design:
| Your key type | Battery access | New battery orientation |
|---|---|---|
| Integrated keyhead transmitter: ignition key and remote buttons in one unit | Twist a thin coin in the slot near the key ring to remove the battery cover | Follow the instructions inside the transmitter |
| Intelligent Access Type 1: removable blade beneath a cover released by side buttons | Hold the side buttons, lift off the cover and remove the blade; separate the case at the illustrated pry points | + facing downward |
| Intelligent Access Type 2: blade released by a slider on the back | Remove the blade, then twist a thin coin under the tab hidden behind the blade’s head | + facing downward |
These methods come from Ford’s replacement instructions, pages 60–62. For Type 1, consult the manual’s illustrations before inserting a screwdriver. Stop if the release or case does not match your fob.
Remove the old cell carefully, install the replacement fully in its holder, and reassemble the cover and blade. Ford says not to wipe away grease on the battery terminals or circuit board, and not to touch the contacts or board with the screwdriver. On Type 2, use a coin—not the backup key—to lift the battery cover.
Test before considering programming
Try lock and unlock beside the vehicle after reassembly. If the remote still fails, recheck the battery code, polarity and seating, then compare operation with a spare key if available.
A normal battery change does not require reprogramming: Ford states that replacing the battery will not delete the transmitter from the vehicle and that it should operate normally. Buying a different key is a separate programming task. Ford’s battery-replacement note
