MCKB042 — Solder-Free Adapter for Buick 7-Button Smart Keys

This Buick 7-button smart key remote — with lock, unlock, hatch, remote start, panic, and left/right sliding side door controls — runs on an NCF29XX chip board that needs a precise, stable connection for reliable programming. The MCKB042 is a dedicated solder-free adapter built specifically for this Buick key shape, allowing locksmiths to connect directly to the PCB without soldering. It’s designed to pair with the CNP259 Super NXP Killer and other compatible NXP-focused programmers, giving shops a fast, repeatable way to handle this advanced multi-function remote.
