A 2017 Ford F-150 integrated keyhead transmitter that works only at close range, responds intermittently or stops locking and unlocking the truck may simply have a weak coin cell. This guide covers the original integrated keyhead transmitter with the flip-out metal key blade. Ford specifies one CR2032 3-volt lithium coin battery for that remote. It does not cover the separate intelligent-access transmitter, which Ford documents with two CR2025 cells and a different opening procedure.
There is no dedicated OBD-II trouble code that proves a key-fob battery has failed. Compare the symptoms with a known-working spare and confirm the remote style before buying anything. A damaged case, wet circuit board, failed button, vehicle receiver fault or door-lock problem can resemble a weak battery.
Easy, with delicate case clips
10–20 minutes
About $7–$15 for a multipack; planning estimate
Do not recharge, crush, puncture, open, short, heat or burn this primary lithium cell. Stop if the remote case is cracked, the battery has leaked, a contact is bent or the case will not latch securely. Ford warns against touching the battery contacts or printed circuit board with the screwdriver.
Featured battery and exact package
Energizer CR2032 3-volt lithium coin batteries, six-pack; ASIN B0002RID4G. Amazon identifies the selected variation as a six-pack, model CR2032, model name “3V Lithium Coin Cell 2032,” UPC 039800039170. The package contains six batteries; the covered F-150 remote uses only one. A remote, shell, key blade, screwdriver, tape and programming service are not included.
The manufacturer’s CR2032 data identifies a 3.0-volt lithium/manganese-dioxide coin cell with IEC designation CR2032. It is about 20 mm in diameter and 3.2 mm thick. Match the marking on the original cell and Ford’s manual. Do not substitute a thinner CR2025 or a rechargeable look-alike simply because its diameter is similar.

Fitment: identify the remote before opening it
| Vehicle or remote | Coverage | Selection check |
|---|---|---|
| 2017 Ford F-150, US/Canadian-market original integrated keyhead transmitter | Covered | Flip-out metal key blade released by a button; Ford specifies one CR2032 cell. |
| 2017 F-150 intelligent-access transmitter | Not covered | Ford specifies two CR2025 cells and a different opening sequence. Do not install this guide’s CR2032. |
| Aftermarket remote or replaced shell | Not automatically covered | Its holder and opening method may differ. Follow the remote manufacturer’s instructions. |
| Other F-150 years or other Ford models | Not established here | A similar-looking case is not fitment proof; check the exact owner’s manual. |
Engine, cab, bed, drivetrain and transmission do not select the cell in this battery-only job; the actual transmitter type does. Trim labels are not a safe shortcut because keys can be replaced during a truck’s life. If your case lacks the flip-out blade or its internal layout differs from Ford’s manual illustrations, stop.
Symptoms and diagnosis before replacement
- Reduced working range: the remote works near the truck but not at its former distance.
- Intermittent response: lock, unlock, panic or remote-start functions require repeated presses.
- One remote works and the other does not: a comparison with a known-good spare supports checking the weak remote’s cell.
- Visible damage or moisture: points to a case or circuit-board problem, not merely normal battery depletion.
Test from the same location and use deliberate button presses. If both remotes fail, only one door fails to lock, or other vehicle electronics are acting up, diagnose the truck rather than buying more coin cells. A door-lock actuator, wiring, fuse, vehicle battery, receiver or configuration issue can produce similar symptoms. Radio-frequency interference can also reduce range temporarily.
A routine battery change does not prove that a replacement key is programmed to the vehicle, and it does not erase or add keys. Lost-key programming is a separate security procedure. If the truck starts normally with the mechanical key but remote buttons remain dead after a correctly installed fresh battery, inspect the remote for damage or consult a qualified locksmith or Ford service department.
Tools and supplies
| Tool or Supply | Exact Product | Product Link | Purpose and Selection Check |
|---|---|---|---|
| Required replacement cell | Energizer CR2032, 3 V lithium coin batteries, six-pack, B0002RID4G | Exact battery package | Use one only after confirming the integrated keyhead transmitter. Keep remaining cells sealed and secured. |
| Required opening tool | Clean, narrow flat-tip screwdriver already owned | No purchase needed | Ford calls for a screwdriver at the illustrated clip position. It must fit without being forced; keep it off contacts and the circuit board. |
| Required disposal supply; purchase optional | Scotch Super 33+ vinyl electrical tape, 0.75 in × 12.5 yd, B000H5Y3BA | Electrical tape option | Cover the removed cell’s terminals as CPSC directs. Existing suitable non-conductive tape is enough; never tape the installed cell. |
| Work surface | Clean, well-lit table and shallow parts tray already owned | No purchase needed | Keeps the cell and cover accounted for. Avoid carpets, seat gaps and areas accessible to children or pets. |
No scanner, torque wrench, lift, vehicle-battery disconnect, lubricant or programming subscription is required for the manual’s transmitter-battery procedure. No threaded fastener is disturbed, so there is no torque specification. Do not spray cleaner into the remote or use metal tools to bridge battery contacts.
Estimated DIY versus professional cost
| Cost item | Planning allowance | Assumption |
|---|---|---|
| Six-cell battery package | About $7–$15 | Planning range, not a current Amazon quote; five cells remain. |
| DIY tools and consumables | $0–$3 incremental | You already have a suitable screwdriver, work surface and tape. |
| DIY total | About $7–$18 | Battery-only work on an undamaged original remote. |
| Locksmith, parts counter or shop | About $15–$50 | Cell plus a small service charge; ask what is included. |
These are broad estimates, not local quotes. A cracked shell, failed transmitter, new key, cutting or programming is excluded and can cost substantially more.
Numbered replacement steps
- Confirm the transmitter. Verify the 2017 F-150 integrated keyhead transmitter with a button-released metal key blade. Confirm CR2032 in Ford’s manual and, when opened, on the removed cell. Prepare one fresh cell and disposal tape.
- Release the key blade. Press the transmitter button and swing the metal key fully out before beginning. This exposes the case arrangement shown in the manual and keeps the blade from snapping out unexpectedly.
- Release the battery-cover clip. Insert a correctly fitting flat screwdriver only at Ford’s illustrated position. Gently push the clip, then press it down to release the battery cover. Do not twist aggressively or lever against the printed circuit board.
- Remove the cover carefully. Lift away the released battery cover without scattering the cell or disturbing internal pieces. Note exactly how the cover, holder and old cell sit.
- Remove and secure the old cell. Ford directs inserting the screwdriver in the shown position to release the battery. Keep its tip away from the contacts and circuit board. Lift out the cell, account for it immediately and cover both faces/terminals with non-conductive tape for a battery-collection center.
- Install one fresh CR2032. Handle the new cell by its edges. Ford specifies the positive (+) face upward. Seat it flat in the holder without bending contacts. Stop if it rocks, does not match the removed cell or requires force.
- Reinstall the cover. Align the battery cover and press it into place until the clips are fully engaged. Inspect the full seam. The case must not gape or release the cell during normal handling.
Final inspection and functional checks
Check that the key blade releases and folds normally, all buttons move freely and the cover is flush. Keep the truck unlocked or have the mechanical key available for the first test. From a normal nearby position, test lock, unlock, panic and—if equipped on this exact remote—remote start according to the owner’s manual. Confirm the intended doors respond.
The Ford manual’s battery-change procedure does not specify reprogramming after a routine cell swap. If the remote remains inoperative, reopen it once to verify CR2032, positive side up, flat seating and intact contacts. Persistent failure calls for diagnosis; do not bridge contacts with foil, stack cells, bend terminals repeatedly or follow an unrelated “reset” sequence.
Common mistakes to avoid
Confusing the two Ford transmitters: the intelligent-access remote uses a CR2025 and different steps. Forcing the clip: a mismatched screwdriver or wrong pry point can crack the cover. Touching electronics with the tool: Ford specifically warns against contacting the battery terminals or printed circuit board. Reversing polarity: the integrated keyhead transmitter’s CR2032 installs positive side up. Leaving a used cell loose: tape it immediately and keep it out of reach. Assuming every remote fault is the battery: water, impact, worn buttons and vehicle-side faults need separate diagnosis.
Frequently asked questions
Does every 2017 F-150 remote use CR2032?
No. Ford’s 2017 manual specifies CR2032 for the integrated keyhead transmitter, but CR2025 for the intelligent-access transmitter. Identify the physical remote before ordering or opening it.
Do I need to program the remote after changing the cell?
Ford’s battery-replacement sequence does not include programming. A routine cell swap retains the existing transmitter. Programming a new or lost key is a separate procedure.
Why buy six cells when the remote uses one?
The featured Amazon variation is a six-pack and one cell is used per covered remote. A smaller correctly identified CR2032 package may be more practical if you cannot store spares securely or will not use them before their labeled date.
Will a CR2025 fit?
It shares the nominal diameter but is thinner. Do not substitute it in the integrated keyhead transmitter; use Ford’s specified CR2032. The CR2025 belongs to the separately documented intelligent-access transmitter.
Can a weak remote battery trigger the check-engine light?
No dedicated OBD-II code proves this coin cell is weak, and the check-engine light is not a remote-battery diagnosis. Investigate engine or emissions warnings separately.
Where can I ask a truck-specific follow-up?
Use the Ford F-150 chatroom and browse the F-150 repair-guide hub. Describe the remote style and symptoms, but do not post key codes, security identifiers, VIN photos or registration details.
