Lockey EC781-B-V – Frequently Asked Questions

1) Which keypad orientation do I order for a Lockey EC781, and does it depend on the cabinet door?
Three keypad orientations are offered: vertical, right handed horizontal, and left handed horizontal. Pick based on how the lock sits on the face of the cabinet or drawer. A tall cabinet stile usually takes the vertical keypad, while a drawer front or a wide shallow door takes a horizontal keypad, with right or left handed chosen so the keypad reads upright for the user. Each orientation is also available in black, silver, or white.
2) What size cam does the Lockey EC781 take, and what spindle length comes with it?
The EC781 works with standard cams from 1/4 inch to 1-1/2 inch, and ships with a 16mm standard spindle. That range covers most cabinet and drawer face thicknesses with a conventional cam, so if you are replacing a keyed cam lock you can often reuse the same cam geometry.
3) How much room do I need on the cabinet face to mount the EC781?
Plan for a lock body of 140mm (5-1/2 inches) long by 41mm (1.61 inches) wide, projecting 32.5mm (1.28 inches) deep. On a horizontal install that 5-1/2 inch run has to fit across the drawer front; on a narrow door stile the vertical orientation keeps the 41mm dimension across the stile. Mounting is available in 2 point or 3 point configurations.
4) What happens if the batteries die in a Lockey EC781 with medication or chemicals locked inside?
There is a mechanical key override, and two keys ship with the lock. If the batteries go flat or a code is lost, you open it with the key. The battery condition indicator is there to warn you before it gets to that point.
5) What is the alternative to the Lockey EC781 if I want a key-only cabinet lock with no batteries or codes?
The Lockey EC781 is a battery-operated electronic cabinet lock running on two AA batteries with a keypad and coded access. If you want purely mechanical key operation with nothing to power or program, the Sargent 4142 is a horizontal cabinet lock with a 6-pin brass cylinder, and the Sargent 1655 is a 6-pin cabinet lock with field reversible handing. Those two are keyed-cylinder locks, so access is controlled by key distribution rather than by master, sub-master and user codes.
6) I need cabinet locks that tie into an existing keying and security system - is the EC781 the right choice?
The EC781 manages access electronically with its own code hierarchy and includes 2 override keys, so it stands on its own rather than rolling into a facility key system. If the cabinets need to fall under an existing keyed program with security system integration, the Sargent KESO F1 4152 Series cabinet lock for drawers is built for that integration, and the Sargent KESO F1 4252 Series offers the same KESO F1 platform with field reversible operation.
7) For pool chemical cabinets, can I substitute a Sargent cabinet lock for the Lockey EC781?
Not on equal footing for that environment. The EC781 is a zinc die-cast cabinet lock specifically engineered for wet and chlorinated areas such as pool and aquatic equipment cabinets, water treatment control panels, and chemical storage. The Sargent 4142 and 1655 are 6-pin cylinder cabinet locks and the KESO F1 4152 and 4252 are drawer locks for keyed security systems - they are cabinet locks, but chlorine-environment construction is the EC781's distinguishing feature.
8) Does the Lockey EC781 need wiring or a power supply?
No wiring. The EC781 runs on two AA batteries, with alkaline batteries included, and gives up to 80,000 cycles per pair plus a battery condition indicator. That makes it practical for cabinets where there is no power run available, which is common in pool rooms and remote storage.
9) Can I give maintenance staff their own codes on the EC781 without handing out the master code?
Yes. The code structure is tiered: an 8 digit master code, a 6 digit sub-master code, 4 digit user codes, and a 6 digit technician code. It runs in Public, Private, or Remote Allocation System (RAS) mode, so a facility can issue short user codes to staff or occupants while administration keeps the master. There is also an auto unlock mode and the keypad beep can be switched off.
10) Should I use a keypad cabinet lock like the EC781 or a keyed cylinder cabinet lock?
Go keypad when the cabinet is shared, users change often, or you do not want to issue and chase keys. Go keyed when the cabinet needs to sit in an existing master key system. For keyed cam-style cabinet locks ZenSupply carries Sargent options including the 1655 6-pin cabinet lock and the 4142 horizontal cabinet lock with a 6-pin brass cylinder, plus the KESO F1 4152 and 4252 drawer locks for facilities tied into a high security key system. The EC781 is the choice when the driver is codes instead of keys, and when the environment is wet or chlorinated.
11) The EC781 has to be ordered in a specific keypad handing - is there a cabinet lock I can reverse in the field instead?
The EC781 keypad orientation is selected at order time in left handed, right handed, or vertical, so handing is fixed by the part you buy. For a lock you can flip on site, the Sargent 1655 is a 6-pin cabinet lock with field reversible handing and the Sargent KESO F1 4252 Series offers field reversible operation. Both are keyed cylinder locks rather than keypad locks, so you give up coded access in exchange for that flexibility.
12) What is the difference between the Sargent 4152 and 4252 if I am cross-shopping them against the EC781 for drawers?
Both Sargent options are KESO F1 cabinet locks for drawers: the 4152 Series is described for security system integration, while the 4252 Series adds field reversible operation. The EC781 differs from both in operation rather than application - it is a commercial electronic cabinet lock with a 140mm (5 1/2 in) L x 41mm (1.61 in) W x 32.5mm (1.28 in) D body and up to 80,000 cycles per pair of AA batteries.
13) Will the Lockey EC781 match the other cabinet locks in my facility visually?
Finish choices are black, silver, and white, all three available in any of the three keypad orientations. For a facility standardizing across many cabinets, pick one finish and one orientation per cabinet style and repeat it; the lock is part of the EC Series, so additional units stay consistent.
14) Is the Lockey EC781 a commercial duty lock or a residential one?
It is specified as commercial. Zinc die-cast body, tiered code administration, and up to 80,000 cycles per battery pair put it in facility and MRO service rather than light home use, with typical applications in healthcare medication cabinets, laboratory chemical storage, and industrial wet areas.
