BEST AD433-2 – Frequently Asked Questions

1) Will the BEST AD433-2 combinator cut keys for my Cormax keyway system?
Yes. The AD433-2 is the combinator configured for BEST standard and Cormax keyways, in right-hand operation. If you run premium keyways, M Series, or Peaks, that's a different tool: BEST builds the AD433P series for premium keyways, the AD434 series for M Series, and the AD436/AD437 series for Peaks. Ordering the AD433-2 for a Peaks system gets you a tool that won't serve it.
2) What is a key combinator and why would a locksmith use one instead of duplicating from a pattern key?
A combinator cuts a key to the original masterkeyed code rather than tracing an existing key. Duplicating from a pattern key copies whatever wear and error is already in that key, and each generation compounds it, so by the second, third, and fourth generation copy the cuts have drifted far enough to cause trouble in a masterkeyed system. Cutting to code off the AD433-2 keeps every key inside the original tolerances the system was designed around.
3) I manage a multi-tenant building on a BEST masterkey system. Is the AD433-2 the right tool to add keys in house?
It's the correct tool only if your system runs BEST standard or Cormax keyways, and only in the hands of someone who has your bitting codes and knows how to run a combinator. It cuts to the system's original masterkey codes, so the person operating it needs access to that code list; this is a tool for qualified locksmiths and security professionals, not a counter-top duplicator. Property managers without in-house key control usually keep this with their locksmith.
4) What is the difference between the AD433-2, AD433-3, and AD433-4?
They're the keyway-configuration variants within the same AD433 combinator family. The AD433-2 is the standard and Cormax, right-hand version. The -3 and -4 cover other keyway requirements in the series. Configuration follows the keyway: premium keyways can call for a left-hand or right-hand setup depending on the specific keyway, and patented keyways call for left-hand. Match the model to the keyway family your system was pinned to.
5) Does the BEST AD433-2 come in more than one configuration, or is there only one to order?
One. The AD433-2 ships as a single model with no options to specify, already set for standard and Cormax keyways in right-hand operation. Everything else in the lineup is a separate model number, not a variant of this one.
6) Where can I find BEST's documentation on which keyway my cores use before I order a combinator?
BEST publishes a Key and Core Brochure covering its keyway families, and that's the reference to check your cores against before committing to a combinator model. Keyway identification is the whole decision here, since the AD433-2 only serves standard and Cormax.
