Medeco 54515R0 G – Frequently Asked Questions

1) Does the Medeco XT padlock need to be wired or have a battery in the lock?
No wiring and no battery in the padlock. All power for the Medeco XT electronic padlock comes from the XT rechargeable key, which is sold separately. That is what makes it workable on gates, utility cabinets, and remote yard enclosures where there is no power to run to the lock. Budget for at least one key when you order, because the padlock will not open without one.
2) Will a Medeco XT padlock hold up outdoors in freezing weather?
Rated -40 to 140 degrees F, so it is built for exterior service in cold climates as well as interior use. The shell is stainless steel and the shackle is boron alloy steel chosen for cut and pull resistance, which is the other half of what an outdoor gate or fence application needs.
3) What shackle clearance options does the Medeco 54515G XT padlock come in, and how do I pick?
Two shackle clearances: 1-1/8 inch and 2.375 inch. Measure the gap you need to span, hasp thickness plus chain link or the staple, and pick the taller 2.375 inch clearance if you are going through a chain or a thick gate hasp. The 1-1/8 inch clearance gives less exposed shackle for a cutter to get a tool onto, so use it wherever the hasp allows. Shackle diameter is 5/16 inch on both.
4) Can I put an XT electronic cylinder into padlocks I already own?
The XT lockcase is built to fit Medeco System Series padlocks, so if your site already runs System Series padlock bodies you can move to electronic credentials without swapping every lock body. A range of cylinder formats is available. If your existing padlocks are another brand or another Medeco family, treat this as a full padlock purchase rather than a cylinder swap.
5) How do I handle a lost key on a Medeco XT padlock without rekeying every lock?
You blacklist it. A lost or stolen XT key can be immediately blacklisted so it stops working, which removes the rekeying trip that a mechanical high security system would force on you. That is the main reason facilities with dozens of remote padlocks move to XT: one lost key does not turn into a site-wide rekey.
6) Is the Medeco XT padlock UL listed for high security?
UL 437 Listed, which is the standard for key operated locks tested against picking, drilling, and forced entry attack. Construction backing that up is machined brass cylinder components with hardened stainless steel cylinder inserts, plus the stainless shell. If a spec calls out UL 437 for exterior padlocks on a facility, this meets that callout.
7) Do I need an electronic padlock, or will a high security mechanical padlock do the job?
Go electronic when you need to know who opened what and when, or when keys circulate among contractors and get lost. The XT gives you audit trail and instant key blacklisting, at the cost of buying and maintaining rechargeable keys. If you just need a strong lock on a fixed opening with a stable key holder list, a mechanical padlock is simpler and there is no key to charge. ZenSupply carries mechanical options like the Sargent 858 non key retaining padlock with stainless steel shackle, the Sargent 60-858-2 with a 2 inch stainless shackle, and the Schlage KS23D/KS23F brass padlock with a 5/16 inch shackle, the same shackle diameter as the XT.
8) What comes with the Medeco 54515G XT padlock, and what else do I have to buy?
The 54515G ships as a complete padlock with the XT cylinder installed. What it does not include is the XT rechargeable key, which is sold separately and is required to operate the lock, and the programming software or web hosted platform you will manage credentials through. Order at least one key per technician who will carry it.
9) What is the difference between the Medeco 54515G XT padlock and a Sargent 758 for a key retaining application?
Both cover key retaining operation: the Sargent 758 is a key retaining standard padlock in a US4 satin brass finish, and the Medeco 54515G is available in a key retaining configuration alongside its non-key retaining one. The distinction is the cylinder. The Sargent 758 is a mechanical padlock keyed to a conventional key. The Medeco 54515G runs Medeco XT electronic cylinder technology on a 6-pin cylinder, is UL 437 listed, and takes its power from the rechargeable XT key rather than any wiring. On the Medeco, a lost or stolen key is blacklisted in the system so it stops working; on a mechanical padlock like the 758, a lost key is handled by rekeying.
10) What is the closest equivalent to the Medeco 54515G XT padlock if I need a mechanical high-security padlock with the same 5/16 inch shackle diameter?
The Schlage KS23D/KS23F is a brass padlock with a 5/16 inch diameter shackle, matching the 5/16 inch shackle diameter of the Medeco 54515G. The difference is in how they are keyed and controlled: the Medeco 54515G uses Medeco XT electronic cylinder technology with a 6-pin cylinder, stores audit events in non-volatile memory, and takes all of its power from the rechargeable XT key with no wiring. The Schlage KS23D/KS23F is a brass-bodied mechanical padlock, so it is opened with a mechanical key and produces no audit record. Choose the Schlage where you want conventional key operation at that shackle size, and the Medeco where you need access history and the ability to blacklist a lost key instead of rekeying.
11) I need a non-key retaining padlock with a stainless steel shackle but do not need electronic audit trail - what should I use instead of the Medeco XT?
The Sargent 858 is a non-key retaining padlock with a stainless steel shackle in a US4 satin brass finish, and it covers the same non-key retaining behavior as the Medeco 54515G, which is offered in both non-key retaining and key retaining configurations. The Sargent 858 is a mechanical padlock, so it does not record openings; the Medeco 54515G stores up to 2,000 audit events per cylinder in non-volatile memory and is powered entirely by the rechargeable Medeco XT key. If the requirement is simply that the shackle releases from the body when unlocked, the Sargent 858 meets it. If the account also needs to know who opened what and when, that is the Medeco XT side.
12) Is the Sargent 60-858-2 removable core padlock a substitute for the Medeco 54515G XT padlock?
They solve different problems. The Sargent 60-858-2 is a removable core padlock with a 2 inch stainless steel shackle, so the core can be pulled and swapped to rekey the lock in the field. The Medeco 54515G is an electronic padlock whose lockcase is designed to fit Medeco System Series padlocks and accepts a variety of cylinder formats, with access permissions changed in the XT software at the key rather than by physically replacing a core. If the site standard is interchangeable core and the goal is core rotation, the Sargent 60-858-2 is the right family. If the goal is credential control without touching the hardware, the Medeco XT is.
13) Does the Medeco XT padlock keep an audit trail of who opened it?
Yes. Non volatile memory in the cylinder holds up to 2,000 audit events, and the key itself carries up to 5,000 audit events. For a utility, healthcare, or government site that has to show who touched an enclosure and when, the record survives loss of power because the memory is non volatile.
14) How many locks can one Medeco XT key open before it needs recharging?
One XT key gives 1,500 to 1,800 openings per charge with cylinder unlock time set at 0.8 seconds, and it can carry access rights to as many as 5,000 cylinders. For a technician running a route of remote sites that is a full day of work and then some on a single charge.
15) Is the Medeco XT padlock the right lock for lockout tagout?
No. The XT is a commercial security padlock, and lockout tagout wants a lightweight, non conductive, individually keyed lock that a worker carries. Use a safety padlock instead: ZenSupply stocks the ABUS 74/40 insulated safety padlock with a 6 pin cylinder, 1/4 inch shackle and 1-1/2 inch body, the ABUS 76/40 plastic covered aluminum core padlock with a 1/4 inch shackle, and the ABUS 72/30 anodized aluminum safety padlock with a 1-1/4 inch body and 3/16 inch shackle.
16) I need matching padlocks across a whole property. What does the Medeco XT give me over standard keyed alike padlocks?
Instead of one key that opens everything, each XT key carries its own access list, so a landscaper key can open the gate padlocks and nothing else, and a change is made in software rather than by cutting keys. Each cylinder logs up to 2,000 events, so you can see whether a unit was actually accessed. Bodies are black stainless steel and the same build across the range, so a fleet of them matches visually on the property.
17) For an outdoor utility enclosure, how does the Medeco 54515G XT padlock compare with an ABUS 76/40 or ABUS 74/40?
Shackle size separates them first. The ABUS 76/40 is a plastic-covered aluminum core padlock with a 1/4 inch shackle diameter and a 1 37/64 inch width, and the ABUS 74/40 is an insulated safety padlock with a 6-pin cylinder, a 1/4 inch shackle diameter and a 1-1/2 inch body width. The Medeco 54515G carries a heavier 5/16 inch boron alloy steel shackle in a stainless steel shell, is rated for operating temperatures from -40 to 140 degrees F, and is UL 437 listed. The ABUS 74/40 also uses a 6-pin cylinder, the same pinning as the Medeco 54515G, but it is a mechanical lock. For an exterior utility point where you want the wider temperature rating, drill and tamper resistant construction, and an access record, the Medeco is the fit; the ABUS units are lighter-bodied padlocks at a smaller shackle diameter.
18) Can I use an ABUS 72/30 safety padlock in place of a Medeco XT padlock for lockout on our maintenance program?
No - they are built for opposite jobs. The ABUS 72/30 is an anodized aluminum safety padlock with a 1-1/4 inch body width and a 3/16 inch shackle diameter, the light, color-coded style used for lockout/tagout where each worker holds a personal lock. The Medeco 54515G is a stainless steel security padlock with a 5/16 inch boron alloy steel shackle, drill and tamper resistant construction, and an electronic XT cylinder that logs up to 2,000 audit events. Buy the ABUS 72/30 for energy isolation on a LOTO program and the Medeco 54515G for asset security and access accountability; a padlock chosen for one is not doing the work of the other.
19) We run a Sargent KESO keying system - is the Sargent 82-856 or the Medeco 54515G the right padlock for us?
If the facility is already standardized on KESO, the Sargent 82-856 stays inside that system: it is a non-key retaining padlock in the KESO series with a 2 inch by 2 inch brass case and a stainless steel shackle. The Medeco 54515G is a separate system - a 6-pin Medeco XT electronic cylinder in a stainless steel shell with a 5/16 inch shackle, programmed through stand-alone, network, web, or mobile options with all programming done at the rechargeable key. Moving an opening to the Medeco means adding the XT key and software side, not just the padlock, so it is usually chosen where the mechanical system cannot give you the audit record or the remote permission changes.
20) I need extra shackle clearance to get around a thick hasp - does the Medeco 54515G cover that, or do I need a different padlock?
The Medeco 54515G is offered with shackle clearance of 1 1/8 inch and 2.375 inch, in both non-key retaining and key retaining forms, so the taller clearance handles a thicker hasp or a chain link without changing brands. Among mechanical alternatives, the Sargent 60-858-2 is built with a 2 inch stainless steel shackle if the opening needs that reach without the electronic cylinder. Match the clearance to the hasp stack first, then decide whether the opening needs the XT audit trail.
21) How is the Medeco XT cylinder pinned, and does that matter for keying?
It is a 6 pin cylinder, but with XT the credential is electronic rather than mechanically cut, so access is granted and revoked in software at the key instead of by pinning a new key. Programming is done at the key and supports stand alone, network, web, and mobile options through a local software client or a web hosted platform.
22) Which padlock should I specify for a marine or coastal gate - the ABUS T84MB/30 or the Medeco 54515G XT?
The ABUS T84MB/30 Nautic is a black sleeve padlock with a 13/64 inch shackle diameter and a 1 17/64 inch body width, built as a small marine-style lock and supplied in a set of three. The Medeco 54515G is a far heavier unit for the same exposure class: a stainless steel indoor/outdoor weather-resistant body with a black lockbody, a 5/16 inch boron alloy steel shackle, and an operating range of -40 to 140 degrees F. For securing a coastal asset that needs real attack resistance and a record of every opening, the Medeco is the specification; the T84MB/30 suits light securing tasks at a much smaller shackle size.

    Solid Lock for Security Enthusiasts

    Posted by Bradley on Oct 2nd 2023

    I recently snagged the Medeco XT Indoor/Outdoor Padlock from Zensupply, and it's a real gem for security-minded folks. The 5/16" shackle diameter adds a robust layer of protection. But, here's the rub: the non-key retaining feature might not be for everyone – you've got to stay extra vigilant not to lose the key! Overall, great for those who prioritize security (like me).

    Sturdy Padlock for Peace of Mind

    Posted by Taylor on Sep 21st 2023

    I've been using the Medeco XT Indoor/Outdoor Padlock, and it's been impressive. The non-key retaining design is practical, and the 5/16" shackle diameter adds to its durability. However, it's a bit weighty for a padlock, which might be a drawback if portability is a concern. Overall, it's a solid choice for securing your belongings.

    Lock It Down with Medeco XT Padlock - My Take

    Posted by Alexander on Aug 1st 2023

    The Medeco XT Padlock is a beast! I love the convenience of its non-key retaining feature, no more fumbling with keys. Plus, it's durable for both indoor and outdoor use. But, here's the deal, the 5/16" shackle might be a bit small for some applications. Overall, it's a solid choice for security, just watch out for the shackle size!
