Help identify your model and equipmentWhat is excluded?
- Other model years and markets; imported Jazz or Fit Hybrid; modified or aftermarket components with a different procedure.
- Requires confirmed configuration: smart-key.
2 Prepare
You can save preparation while your vehicle or equipment is still unconfirmed.
YOUR OBSERVATIONS
Keep the before and after.
Record the original housing match, CR2032 marking, polarity and the actual button response after closure.
Does the assembled remote respond again under the same parked conditions while the cover and built-in key remain secure?
3 Follow the steps
Confirm compatibility and choose the readiness branch before recording steps.
4 Check the result
- 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?
Select what you actually observed. If you have only prepared the plan, record that instead.
Stop and get help if
- 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.
