MechanMagic's KR5V2X 5-button smart proximity key fob is a direct replacement remote for Honda Civic 2016–2021 models, preloaded with battery and electronics and ready to be cut and programmed by a locksmith or dealer.

How do I install and program this replacement key fob?

The MechanMagic fob arrives with battery and electronics already installed, but it must be cut and professionally programmed before use. Programming requires a qualified locksmith or a Honda dealership with the appropriate diagnostic tools; this is not a DIY plug-and-play remote.

What features and quality checks does this key fob include?

Are there any limitations I should know about?

This replacement is a transmitter-only smart remote and does not include dealer programming services or key cutting. It will not work with Civics that use a non-proximity standard key system. Verify your existing remote’s FCC ID and vehicle fitment before ordering.

• Transmitter only — no cutting or programming service included
• Not compatible with non-proximity (standard) keyed ignitions
• Confirm compatibility via your original FCC ID or part number
• Professional locksmith or dealership programming required
