Keedex K-18 Change Key Replacement Set, Includes 12 Change Keys

Change keys are the small tools a locksmith uses to re-combinate or reset a lock without pulling the whole lock apart. The K-18 gathers the twelve most common change keys into one folding case, so instead of hunting for the one tool that fits a particular lock you fan the set open and pick it. The case itself is engraved with a description of what each key is used for, which is the difference between carrying a set you know and a bag of loose tools.

It is a tool set, not keys cut to a keyway for a door. Change keys are lock-servicing tools used to change a lock's combination; they do not operate an opening and they are not blanks to be cut. If what you need is a key that unlocks a door, this is the wrong item. The K-18 belongs in a locksmith's or maintenance tech's kit.

Twelve keys come in the K-18, and they arrive assembled in the case, not as loose pieces to source one at a time. That is the whole point of the set: the twelve change keys a locksmith reaches for most often, already in hand. Nothing else is needed to use them.

Keedex classes the K-18 as commercial hardware. In practice that means the set is aimed at the locks a locksmith or an in-house maintenance tech meets in office buildings, multi-family, and institutional openings rather than at a homeowner doing one door. A property manager standardizing service across a portfolio is the buyer this set is built for.

The case is engraved with a description of the uses, so the reference travels with the tool. You match the lock you are working on against the engraving instead of carrying a chart or guessing by eye, which matters most for a tech who works across mixed hardware and does not re-combinate the same lock twice in a week.

The keys pivot out of the case knife style, the way blades swing out of a multi-tool, so you select the one you want and leave the rest folded. It stays as one piece in the case rather than twelve separate keys rattling loose in a service bag, which is what makes it practical to carry on a route.

One configuration only, the K-18. There is no size, finish, or handing decision to make on it, so ordering is a single line: the set of twelve keys in the engraved case.
