[ ] Record cell marking/polarity, cover-screw condition and the actual response from the closed remote. https://techinfo.honda.com/rjanisis/pubs/OM/AH/A5A1515OM/enu/A5A1515OM.pdf#page=397 | PDF page 397 DECISION CHECKS Does the original remote key have the small cover screw shown on printed page 395? 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. No matching cover screw, corrosion, damage or a different remote → No response, stripped screw or insecure case: arrange remote service. What did the reassembled remote do? Cover fastened and the remote responds → Did the second button test work with a securely refitted cover screw? No response, stripped screw or insecure case: arrange remote service. → No response, stripped screw or insecure case: arrange remote service. I have only prepared the plan → Plan prepared; no physical maintenance result recorded. Did the second button test work with a securely refitted cover screw? Response repeatable; screw and case secure → Cover fastened and the remote responds The observation or repeat check is still incomplete → Plan prepared; no physical maintenance result recorded. Screw stripped, case insecure or response unreliable → No response, stripped screw or insecure case: arrange remote service. RECHECK Does another parked button check give the same response with the screw and case still secure? After care: __________ Retest: not checked / improved / unchanged / worse If an earlier condition changes, reassess the later checks and result. RESULT CHECK What did the reassembled remote do? Cover fastened and the remote responds Record only the result you actually observed. A saved web checklist is not confirmation that a vehicle has been repaired. Did the second button test work with a securely refitted cover screw? Does another parked button check give the same response with the screw and case still secure? STOP CONDITIONS No matching cover screw, corrosion, damage or a different remote No response, stripped screw or insecure case: arrange remote service. 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. No response, stripped screw or insecure case: arrange remote service.
