Medeco 54715K0 – Frequently Asked Questions

1) Does the Medeco 54715L padlock come with a cylinder, or do I have to order one separately?
The 54715L ships less cylinder. You order the cylinder separately, which is the point of the design: the body accepts Medeco's cylinder range including Medeco 4 (M4) high security and Intelligent Key electronic cylinders, so the padlock can be brought into the same key system as the doors. Plan the order as two lines, body plus cylinder, and specify the cylinder in the keyway your facility already runs.
2) Can Medeco System Series padlocks be master keyed into the building's existing key system?
Yes. The System Series padlock can be ordered keyed alike, keyed different, or master keyed so it falls under the same system as the door hardware. Because it is a 6-pin cylinder configuration, the cylinder you specify has to be a 6-pin Medeco cylinder in your system's keyway for the padlock to key into the existing hierarchy. This is the usual way facilities get gates, cabinets and equipment onto one key with the doors.
3) What is the difference between key retaining and non-key retaining on this Medeco padlock, and which should I order?
Both are offered on the 54715L. Key retaining means the key cannot be withdrawn while the shackle is open, so the lock never gets left hanging unlocked and the key never walks off with a contractor. Non-key retaining lets you pull the key with the lock open, which is what you want when one master key has to open a run of locks on a route and the tech does not want to be tethered to each one. Utility crews and route inspections usually take non-key retaining; secure storage and equipment lockout usually take key retaining.
4) Boron alloy steel or stainless steel shackle on a Medeco padlock, which one for an outdoor gate?
Both shackle materials are offered on this padlock and they trade off differently. Boron alloy steel is the attack-resistant choice, resisting cutting and pulling while keeping ductility rather than going brittle, so it is what you want on an exposed gate or utility cabinet where somebody may come at it with bolt cutters. Stainless steel is the corrosion choice for coastal, wash-down, or chemical exposure. The lock body itself is built indoor/outdoor weather resistant either way.
5) Will a 7/16 inch shackle fit my existing hasp?
The 54715L uses a 7/16 inch diameter shackle, which is heavy for a padlock and will not pass through a light hasp or a small cabinet staple sized for a 1/4 inch or 5/16 inch shackle. Check the hole in your hasp before ordering. If the opening is smaller, you are looking at a lighter padlock instead, for example the Schlage KS23D/KS23F brass padlock at 5/16 inch shackle diameter or an ABUS 76/40 at 1/4 inch. Upsizing the hasp is usually the better answer on a high security opening, since a 7/16 inch shackle is wasted behind a hasp anyone can twist off.
6) What is the closest equivalent to the Medeco 54715L if I need a padlock that takes an interchangeable core instead of a Medeco cylinder?
The Sargent 60-858-2 is a removable core padlock with a 2 inch stainless steel shackle, so the core drops into an existing Sargent core-based key system. The Medeco 54715L is sold less cylinder and accepts Medeco cylinder technologies including Medeco 4 (M4) High Security and Intelligent Key electronic cylinders, with a 7/16 inch boron alloy steel shackle. Choose by which key system the site already runs: a facility standardized on Sargent removable cores keys the 60-858-2 off its existing pinning kit, while a Medeco key control program keys the 54715L.
7) Our buildings are keyed to Schlage. Is there a padlock that keys into that system rather than a Medeco one?
The Schlage KS23D/KS23F is a brass padlock with a 5/16 inch diameter shackle, which is the padlock to look at when the rest of the site's cylinders are Schlage. The Medeco 54715L is sold less cylinder and takes Medeco cylinders, including Medeco 4 (M4) high security and Intelligent Key electronic, and can be ordered keyed alike, keyed differently or master keyed into a Medeco system. Padlocks follow the key system, so the deciding question is which cylinder platform the master key chart is built on, not the lock body.
8) How is a Medeco System Series padlock different from a Sargent 758 or 858 padlock?
The main split is how the cylinder is handled. The Medeco 54715L is sold as a body less cylinder, so you fit a Medeco 4 or Intelligent Key cylinder and bring the padlock into a Medeco key control program. The Sargent 758 is a key retaining padlock supplied in US4 satin brass and the Sargent 858 is the non-key retaining version with a stainless steel shackle, both finished units in the Sargent line. If the site is already standardized on Sargent, the 758 or 858 keeps one keyway across the property. If the requirement is patented key control and UL 437, the Medeco is the one that carries it.
9) Can keys for a Medeco padlock be copied at a hardware store?
No, and that is the reason to buy it. Medeco 4 key control is utility patent protected, and keys are duplicated only by Medeco or an authorized Medeco service outlet at the owner's request. The key also carries a Shuttle Pin movable element, which is a physical component a 3D printed copy cannot reproduce. For a property manager or facilities group tracking who holds keys to gates and equipment, this is what stops the uncontrolled copies that make a rekey necessary.
10) Is the Medeco 54715L padlock rated for outdoor use in weather?
Yes, the body is an indoor/outdoor weather resistant design intended for outdoor environmental exposure, and the extended shackle option is offered on the indoor/outdoor model specifically. Internals are machined brass cylinder components with hardened stainless steel inserts. For salt air or wash-down, order the stainless steel shackle rather than the boron alloy steel.
11) Do I need a removable core padlock, or is a less-cylinder Medeco padlock the same thing?
They are not the same. The 54715L is a less cylinder body, so a cylinder is installed once when the padlock is set up; changing it later is a service operation. A removable core padlock lets a facility locksmith pull the core with a control key and swap it in seconds without disassembly, which is what large campuses use when tenants and contractors turn over. The Sargent 60-858-2 is a removable core padlock with a 2 inch stainless steel shackle if that is the workflow you run. Choose the Medeco when the priority is patented key control and UL 437 attack resistance.
12) Which padlock will not mar a painted or finished surface the way a steel-bodied lock can?
The ABUS 76/40 is a plastic-covered aluminum core padlock with a 1/4 inch shackle diameter and 1-37/64 inch width, and the covered body is what keeps it from scuffing the panel or door it hangs against. The Medeco 54715L is a black-bodied high security padlock with a 7/16 inch boron alloy steel shackle and hardened stainless steel cylinder inserts. On roll-up doors, cabinets and painted equipment where cosmetics matter more than attack resistance, the 76/40 covers the requirement; where the lock has to resist cutting, pulling and drilling, the 54715L is the one built for it.
13) What other padlock offers patent-protected key control at the same level as the Medeco 54715L?
The Sargent 82-856 is a non-key retaining padlock in the KESO series with a 2 inch by 2 inch brass case and a stainless steel shackle, and KESO is Sargent's restricted key control platform. The Medeco 54715L uses a 6-pin cylinder with Medeco 4 (M4) key control, whose utility patent protection prevents unauthorized duplication and whose Shuttle Pin movable element in the key adds protection against 3D printed keys. Both keep duplication inside an authorized channel; which one you specify usually follows the platform the rest of the facility's restricted keys are already cut on.
14) What color is the Medeco System Series padlock body?
Black. On a fleet of gates or utility cabinets the black body reads as the secured opening, which matters when a property manager wants the high security locks visually distinct from the general purpose padlocks on site. The material spec on the lock is stainless steel, with machined brass cylinder components inside.
