Medeco 510600T-06-DLT – Frequently Asked Questions

1) Will the Medeco 510600 cylinder fit a knob or lever lockset, or is it only for padlocks?
Both. The 510600 is a Key-in-Knob/Lever style cylinder that drops into knob-type cylindrical locksets, lever-type cylindrical locksets, bored-type auxiliary deadlatches and deadlocks, and System Series KIK style padlocks. It's a retrofit part, so you upgrade the cylinder without replacing the whole lockset.
2) Which Medeco padlocks does the 510600 KIK cylinder work with?
It's built for Medeco System Series KIK style padlocks, specifically the Medeco 54 Series. If your padlock takes a key-in-knob style cylinder, this is the 6-pin replacement for it.
3) Is the Medeco 510600 a high security UL listed cylinder?
Yes. Medeco M4 Key-in-Knob cylinders are UL437 listed for drill and pick resistance, and the 510600 is certified to ANSI A156.30 Level A for patent-protected key control and physical strength, plus ANSI A156.5 Grade 1 for heavy-use applications. That combination is what a spec calling for high-security cylinders is usually asking for.
4) What do I have to specify when ordering a Medeco 510600 cylinder?
Three things. Keyway technology, either Biaxial or M3. Pinning state: Pinned, Sub-Assembled, or Sub-Assembled No Slider. And finish, from 13 options including 605 Bright Brass, 606 Satin Brass, 609 Antique Brass, 611 Bright Bronze, 612 Satin Bronze, 613 Dark Bronze Oil-Rubbed, 618 Bright Nickel, 619 Satin Nickel, 20 Antique Nickel, 622 Flat Black, 624 Dark Bronze, 625 Bright Chrome, and 626 Satin Chrome.
5) Can I get the Medeco 510600 keyed into my existing Biaxial or M3 master key system?
Yes, the 510600 is offered in both Biaxial and M3 keyway technology, so it can be pinned to an existing Medeco system in either family. Order the cylinder in the same technology as the rest of your system, and take the Sub-Assembled option if your locksmith is pinning it in house. Medeco's utility patent-pending key control restricts unauthorized key duplication, which is the point of keeping a facility on one system.
6) Do I have to replace the whole lockset to put Medeco cylinders on my building?
No. The 510600 is a retrofit cylinder, so you pull the existing key-in-knob cylinder and drop this one in. Medeco builds over 100 cylinder designs and tailpiece configurations, which is what lets a facility standardize on one key system across knobs, levers, deadlatches and padlocks without buying new hardware for every door.
7) What is the difference between the Pinned and Sub-Assembled options on a Medeco KIK cylinder?
Pinned means the cylinder arrives keyed and ready to install. Sub-Assembled is supplied for a locksmith to pin into an existing system, and Sub-Assembled No Slider leaves the slider component out for shops building to their own keying. If you don't run a key machine and a pinning bench, order Pinned.
8) I need the new cylinder to match the lever finish on the rest of my doors. What finishes does the Medeco 510600 come in?
Thirteen, covering the common commercial finishes: 626 Satin Chrome and 625 Bright Chrome, 619 Satin Nickel, 618 Bright Nickel and 20 Antique Nickel, 605 Bright Brass, 606 Satin Brass and 609 Antique Brass, 611 Bright Bronze, 612 Satin Bronze, 613 Dark Bronze Oil-Rubbed and 624 Dark Bronze, plus 622 Flat Black. Match the BHMA number on your existing trim and the cylinder face will read the same.
9) Is a 6-pin Medeco KIK cylinder worth it over a standard 5-pin key-in-knob cylinder?
The six-pin configuration adds pick resistance and expands the key control, which is why it's specified on commercial openings where key duplication is the actual risk, not just lock strength. Combined with the UL437 drill and pick resistance listing on Medeco M4 cylinders, this is a security-driven upgrade rather than a durability one. If nobody is trying to copy your keys, a standard cylinder does the mechanical job.
10) Is the Medeco 510600 cylinder rated for heavy traffic commercial doors?
It's a commercial grade part, certified to ANSI A156.5 Grade 1 for consistent quality in heavy-use applications and built from machined brass components. That covers office buildings, schools, healthcare, government facilities, retail, warehouses and multi-tenant residential.
