BEST BES-5E6A1AR626 – Frequently Asked Questions

1) What is the BEST 5E utility cylinder cam lock actually for?
It's a cam lock cylinder that lets an international mortise lockset be brought onto a BEST masterkeyed system. Instead of ripping out the existing lockset, you replace the cylinder with the 5E, which accepts BEST Eurocylinder and 3C European interchangeable core technology, and the door then keys the same as the rest of your BEST system. It ships uncombinated, so a locksmith pins and keys it to your existing system.
2) Do I have to give the lock brand and model when ordering a BEST 5E cam lock?
Yes, and it's not optional in practice. Fit is determined by the lockset you are retrofitting, so the 5E is specified with the lock manufacturer name and model number to get proper fit and function. Without that, there's no way to pick the right cam type, cam length, mounting position and rotation for your lockset.
3) Does the BEST 5E cam lock come keyed, or do I have to have it keyed?
It comes uncombinated, meaning no pinning and no key. That's deliberate: the point of the 5E is to fold the opening into an existing BEST masterkeyed system, so a locksmith or your in-house key control pins it to your system's keyway and change key. Order the keyway you already use so the cores match the rest of the building.
4) Can I use a standard BEST core in the 5E, or only a European core?
Either. The 5E takes the BEST 3C European interchangeable core, or a standard core when specified with the E option. That matters if you already stock standard BEST cores for the rest of the property and don't want a second core inventory just for the retrofitted international openings.
5) Can I keep the existing international mortise locksets and just change the cylinders?
That's exactly the case the 5E is built for. It replaces the cylinder in a compatible international mortise lockset so you get unified key control without replacing the lock bodies, trim or door prep. The limit is that BEST ties fit to the specific lockset, so the maker and model of what's in your door has to be specified when the cylinder is ordered.
6) What is the difference between a fixed cam and a lost motion cam on a BEST utility cylinder?
A fixed cam moves with the key the whole way, so the cam turns as soon as the key turns. Lost motion gives the plug some free rotation before it picks up the cam, which is what many mortise locksets need so the cylinder can return to the key-pull position without dragging the lock mechanism. The 5E offers both, plus a direct throw member option where the cylinder drives the lock's own actuator instead of a cam. Which one you need is dictated by the lockset you're retrofitting, not by preference.
7) Is the BEST 5E cam lock available in 7-pin as well as 6-pin?
Both. 5E utility cylinders come in 6-pin and 7-pin. Match the pin count to the rest of your BEST system: a 7-pin system needs 7-pin cylinders, and mixing pin counts breaks the masterkeying you installed it for.
8) Where can I find service and keying instructions for BEST E Series cylinders?
BEST publishes an E Series Service Manual covering the family, hosted at zensupply.com/content/pdf/best/E-Series-Service-Manual.pdf. For the install itself, work from the instructions for the lockset the cylinder is going into, since the cam and mounting setup is driven by that parent device.
