SDC CYL-6KDQ – Frequently Asked Questions

1) What is the difference between the SDC CYL-6KAQ and CYL-6KDQ mortise cylinders?
Keying is the only thing you are choosing between. CYL-6KAQ is the keyed alike version, so every cylinder you order on that number opens with the same key, and CYL-6KDQ is keyed different, so each one gets its own key. Both are the same 6-pin mortise cylinder otherwise. Keyed alike is what a property manager wants when one key should cover a run of doors; keyed different is what you order when each tenant or room has to stay separate.
2) Will an SDC 6-pin mortise cylinder thread into a standard commercial mortise lock body?
Yes. The SDC CYL-6K is a standard 1-1/8 inch mortise cylinder, which is the common size for commercial mortise lock bodies and mortise-prepped trim, so it threads into a standard cylinder prep without modifying the lock. Mortise cylinders thread in on a 1-5/32 inch, 32-threads-per-inch shank, which is uniform across the trade, so the length and the cam are what you match, not the thread.
3) Is a 1-1/8 inch mortise cylinder long enough for my door, or do I need a longer one?
1-1/8 inch is the base length and it suits a standard mortise lock in a 1-3/4 inch commercial door with normal trim. Where it comes up short is when something adds thickness in front of the lock: a thick escutcheon, an armored front, or a cylinder collar or ring stack. If the cylinder face sits proud or recessed by more than about an eighth of an inch once it is threaded home, you are into a 1-1/4 or 1-1/2 inch cylinder instead. Measure from the lock case cylinder pocket out to the finished trim face before ordering.
4) Is a mortise cylinder the right type, or do I need a rim cylinder or a key-in-knob cylinder?
Match the cylinder to the lock, not the door. A mortise cylinder like the CYL-6K threads into the lock body or trim and drives a cam, which is what a mortise lock, most electric strikes with cylinder control, and cylinder-dogged exit trim take. A rim cylinder is flat-backed with a tailpiece and mounts through the door onto a rim exit device or a rim night latch. A key-in-knob or lever cylinder is a figure-eight or clover shape that drops into the knob itself. They do not interchange, so pull the existing cylinder and look at the back before you order.
5) Does a 6-pin cylinder give me better key control than a 5-pin?
Six pins buy you two things over five: more possible key combinations, so the odds of a stray key crossing into your system drop, and a longer pin stack that is harder to pick. That matters most on a master keyed building where the same bitting depths get reused across a lot of doors. The SDC CYL-6K is 6-pin throughout, keyed alike or keyed different.
6) Can I standardize a whole building on the SDC CYL-6K mortise cylinder?
That is the usual reason to buy it. Order the keyed alike CYL-6KAQ where you want one key to run a group of openings, common areas, mechanical rooms, a maintenance run, and the keyed different CYL-6KDQ where each door needs its own key. It is a commercial-rated cylinder, and the standard 1-1/8 inch mortise size means the same part carries across office, school, healthcare, retail, industrial, multi-tenant residential and municipal openings that already use mortise locks.
7) What do I need to check on the cam before ordering an SDC mortise cylinder?
The cam is what actually retracts the lock, so it has to suit the lock body you are putting it into. Pull the old cylinder and compare the cam shape and its rotation before swapping. The other thing worth checking at the same time is the collar or ring: if the old cylinder sat on a spacer ring to bring it flush with the trim, reuse it, because a 1-1/8 inch cylinder set without it can sit recessed in the prep.
8) Can I get more SDC cylinders later keyed to match the ones I already installed?
Keyed alike works within an order, not across the catalog. The CYL-6KAQ ships a group keyed to each other, so plan the group up front and buy the whole run at once rather than adding to it months later. If the openings need to stay separate anyway, or you are keying them into an existing masterkey system through a locksmith, order the keyed different CYL-6KDQ and have them pinned to your system.
