Universal High-Security Key
The Mul-T-Lock MTKEY-MB is a black nylon head key with an integrated magnet, manufactured as a master blank for the 240B, 248B, 264B, and 206B keyways. It is supplied new and keyed different, intended for locksmiths or property managers who need a single compatible blank to cut working keys for those specific Mul-T-Lock cylinders. An image of the security card must be provided before the key can be cut.
Durable Nylon Construction
The black nylon head resists everyday wear and corrosion while remaining lightweight on a keyring. The integrated magnet adds a small convenience for attaching the key to metal surfaces without affecting the mechanical operation. No batteries or electronics are present, so there is no power draw, heat, or noise to consider during normal use.
Precision Cutting Required
The blank is supplied uncut and requires professional key-cutting equipment matched to the listed keyway profiles. Supplying a clear image of the security card is a mandatory step before any cutting service can proceed, ensuring the finished key matches the authorised code. The keyed-different configuration means each cut key will operate only its designated cylinder.

Questions about this item
How do I get this MTKEY-MB key cut for my 240B lock?
You must send a clear image of your Mul-T-Lock key card so the supplier can verify authorisation before cutting the key to match the 240B, 248B, 264B or 206B keyway.
What part of this key will need replacement first?
The black nylon head or the integrated magnet may crack or lose adhesion over time, while the metal blade itself typically outlasts the plastic components.
What stops me from ordering extra copies of this key later?
Each additional copy still requires a fresh image of the original key card; without that proof of ownership the key cannot be cut for the 240B, 248B, 264B or 206B profiles.
