Lost your key fob or is it cracked and falling apart? This is a complete replacement 5-button keyless entry remote that's compatible with several Honda models. It's not just a shell – it includes the new electronics inside. It fits Honda Civic (EX, EX-L, Sport Touring 2017-2018), Honda CR-V (various trims 2017-2018), and Honda Pilot (2016-2019, various trims). Check your specific year and trim to be sure! It matches OEM part numbers 7812D-V2X and KR5V2X and uses a 433MHz frequency with a 47-chip transponder. SUPER IMPORTANT: This is a BLANK remote and key. To make it work with your car, you MUST take it to a qualified locksmith or dealership for two things: 1. PROGRAMMING the remote to your car's immobilizer system, and 2. CUTTING the physical metal key blade to match your door/ignition. We highly recommend you get the remote PROGRAMMED first to confirm it works, THEN have the key cut. This is a great, cost-effective way to get a spare or replace a broken fob without paying dealer prices for the whole unit. Package includes one black key fob.
