Replacing a decorative crest does not alter transponder electronics or mechanical key performance when installed correctly.

If your key has electrical or programming issues, consult an authorized service provider rather than relying on cosmetic replacement alone.

• Cosmetic replacement only — does not change electronic operation
• OEM part reduces risk of fit-related damage
• Seek dealer help for programming or electrical faults
• Keep original parts if you need dealer validation later
