Buying Guide

Confirm vehicle compatibility

Match the shell to your car model/generation and key type to ensure button alignment and transponder compatibility

Check construction material

Choose zinc alloy, ABS plastic, or silicone based on desired durability, scratch resistance, and weight

Consider RF shielding needs

If relay-theft is a concern, opt for a Faraday-lined box or pouch to block RFID/key fob signals

Look for included hardware

Kits that include screws, inserts, and pry tools simplify swapping shells and ensure a secure fit

Prioritize button and cutout precision

Accurate button molds and cutouts reduce accidental presses and preserve remote functions
