GROUNDWORK — Replace the smart-entry key battery Task: fit-smart-key-battery | Content version 2.0.0 Source page: https://csl-12-auto-repair.pages.dev/tasks/fit-smart-key-battery/ MODEL / APPLICABILITY [{"modelId":"fit-2015-us","market":"US","year":2015,"engine":"1.5L gasoline","configurations":["smart-key"]}] EXCLUSIONS Other model years and markets; imported Jazz or Fit Hybrid; modified or aftermarket components with a different procedure. Requires confirmed configuration: smart-key. PREPARE [ ] Park in a safe place away from traffic. Work with the vehicle stationary, parking brake set and ignition off unless a step explicitly calls for a parked functional check. [ ] Does your original remote have a removable built-in key, matching the Smart Entry Remote drawing on printed page 396? [ ] Keep children and pets away from tools, fluids and coin cells. Never enter underneath the vehicle. [ ] Coin wrapped in a soft cloth [ ] Clear work tray [ ] One CR2032 coin cell; match the original cell and polarity. [ ] Local coin-cell recycling container OBSERVE & RECORD Observation date: __________ Vehicle / equipment confirmed: __________ Record the original housing match, CR2032 marking, polarity and the actual button response after closure. Removable-key housing match: __________ Cell marking and fitted polarity: __________ Parked button response: __________ | Choices: Responds; Intermittent; No response; Not tested Cover and built-in key retention: __________ Before care: __________ STEPS 1. [ ] Compare the remote with the official Smart Entry Remote drawing. A conventional key with a screw uses a different task and a CR1620; do not substitute this guide. https://techinfo.honda.com/rjanisis/pubs/OM/AH/A5A1515OM/enu/A5A1515OM.pdf#page=398 | PDF page 398 https://techinfo.honda.com/rjanisis/pubs/OM/AH/A5A1515OM/enu/A5A1515OM.pdf#page=397 | PDF page 397 2. [ ] Remove the built-in key. Lay the remote on a clear tray so loose buttons cannot fall away. https://techinfo.honda.com/rjanisis/pubs/OM/AH/A5A1515OM/enu/A5A1515OM.pdf#page=398 | PDF page 398 3. [ ] Wrap a coin with a soft cloth and carefully pry at the cover edge shown in the manual. Remove the upper half without losing the buttons. https://techinfo.honda.com/rjanisis/pubs/OM/AH/A5A1515OM/enu/A5A1515OM.pdf#page=398 | PDF page 398 4. [ ] Note the fitted cell’s polarity before removing it. Install a CR2032 with the same correct polarity; keep the cell out of children’s reach. https://techinfo.honda.com/rjanisis/pubs/OM/AH/A5A1515OM/enu/A5A1515OM.pdf#page=398 | PDF page 398 5. [ ] Seat the cover and built-in key, then test the remote buttons near the stationary car. Keep a working key available; do not lock your only key inside. https://techinfo.honda.com/rjanisis/pubs/OM/AH/A5A1515OM/enu/A5A1515OM.pdf#page=398 | PDF page 398 6. [ ] If it still fails, stop reopening or forcing the housing and arrange remote inspection. Dispose of the old cell under local rules. https://techinfo.honda.com/rjanisis/pubs/OM/AH/A5A1515OM/enu/A5A1515OM.pdf#page=398 | PDF page 398 7. [ ] Record the original housing match, CR2032 marking, polarity and the actual button response after closure. https://techinfo.honda.com/rjanisis/pubs/OM/AH/A5A1515OM/enu/A5A1515OM.pdf#page=398 | PDF page 398 DECISION CHECKS Does your original remote have a removable built-in key, matching the Smart Entry Remote drawing on printed page 396? Yes — ready for this check → Continue with the steps, stopping if the real component differs from the manual. Not yet / not sure → Preparation saved. Return when the condition is confirmed; leave the vehicle untouched. Remote is wet, corroded, broken, swollen or a different design → Still unresponsive, loose cover or uncertain polarity: have the remote checked rather than forcing its contacts. What happened after reassembly and a stationary button test? Cover secure, built-in key retained, remote responds to the button test → Did a second parked button check confirm response with secure cover and key retention? Still unresponsive, loose cover or uncertain polarity: have the remote checked rather than forcing its contacts. → Still unresponsive, loose cover or uncertain polarity: have the remote checked rather than forcing its contacts. I have only prepared the plan → Plan prepared; no physical maintenance result recorded. Did a second parked button check confirm response with secure cover and key retention? Responds again; cover and built-in key secure → Cover secure, built-in key retained, remote responds to the button test The observation or repeat check is still incomplete → Plan prepared; no physical maintenance result recorded. Intermittent response, insecure cover or uncertain cell fit → Still unresponsive, loose cover or uncertain polarity: have the remote checked rather than forcing its contacts. RECHECK Does the assembled remote respond again under the same parked conditions while the cover and built-in key remain secure? After care: __________ Retest: not checked / improved / unchanged / worse If an earlier condition changes, reassess the later checks and result. RESULT CHECK What happened after reassembly and a stationary button test? Cover secure, built-in key retained, remote responds to the button test Record only the result you actually observed. A saved web checklist is not confirmation that a vehicle has been repaired. Did a second parked button check confirm response with secure cover and key retention? Does the assembled remote respond again under the same parked conditions while the cover and built-in key remain secure? STOP CONDITIONS Remote is wet, corroded, broken, swollen or a different design Still unresponsive, loose cover or uncertain polarity: have the remote checked rather than forcing its contacts. A part, label, connector or fastener differs from the cited manual; access requires raising the vehicle; you cannot identify the correct component. SERVICE HANDOFF Take the recorded observations, their dates and any actual work history to the service provider. Still unresponsive, loose cover or uncertain polarity: have the remote checked rather than forcing its contacts.
