X AUTOHAUX Replacement BMW Key Fob 2-Pack 315MHz KR55WK49127 Compatible with 2006–2014 3-Button, 46 Chip, Batteries Included

This pair of X AUTOHAUX replacement remote key fobs is built to match the KR55WK49127 / KR55WK49123 style used by many BMWs from the mid‑2000s into the early 2010s. Each fob operates on 315MHz and carries a built‑in 46 transponder chip—designed to be programmed and cut at a locksmith or dealer so the remotes work with your vehicle. They are semi‑intelligent remotes: they control locks and trunk release but do not support one‑touch engine start.

Which BMW models will these remotes work with?

These replacements are intended for a wide range of BMW series from 2006 through roughly 2014; compatibility depends on matching the original fob’s FCC/part number and button layout. Always compare the photos and part numbers before ordering.

How do I program and get these keys cut so they work with my car?

Programming and blade cutting must be performed by a qualified locksmith or a dealership. A working factory key is required during the addition of a new key to the vehicle’s system in most cases.

• Bring the new remote and your vehicle to a locksmith or dealer for programming
• A functional original key or key fob is typically required to add a new one
• Have the metal key blade cut to match your door/ignition by a professional
• Confirm programming fees and procedures with multiple locksmiths if needed

Who this product is for: drivers who own compatible BMW models from the 2006–2014 era and need a reliable replacement or spare remote without paying OEM pricing. It’s ideal for vehicle owners who can access a locksmith or dealer for programming and have an original working key to complete the pairing. If your vehicle requires proximity one‑touch start, this semi‑intelligent remote will provide remote locking and trunk control but not push‑button ignition operation.
