1. Compare the complete key shape
Place the original key beside the product image. Compare the full housing outline, thickness, side profile, blade or emergency-key opening and key-ring attachment. A vehicle name or model year alone is not enough because more than one key profile can be used.
2. Match the complete button layout
Count every button, then compare each symbol, position and spacing. A three-button key is not a match merely because another key also has three buttons; the complete button layout and housing openings must agree.
3. Use printed identifiers as a cross-check
Record any FCC ID, OE number or part number that is clearly printed on the original key. Use identifiers to narrow candidates, but do not let an identifier override a visible shape or button-layout mismatch.
4. Send useful confirmation photos
Provide sharp, uncropped front and back photos in neutral light, plus a side view when thickness or an opening is unclear. Keep every button, edge and attachment point visible.
5. Confirm before ordering
Review the remaining candidate beside the original key. If more than one profile is possible, request human confirmation instead of treating a Finder result, vehicle year or first visual similarity as a guaranteed fit.
