Lockey 1600-SCMG-DC – Frequently Asked Questions

1) Will the Lockey 1600 keyless knob lock fit a 1-3/4 inch commercial door?
Yes. The Lockey 1600 mechanical keyless knob lock covers door thicknesses from 1-1/8 inches to 2 inches, so a standard 1-3/4 inch commercial door sits in the middle of the range. That range also picks up older 1-3/8 inch interior doors and thicker exterior slabs up to 2 inches without any special order. Past 2 inches you need the optional Extension Kit, which takes it as far as 5 inches.
2) Does the Lockey 1600 work with a 2-3/8 or a 2-3/4 inch backset?
Both. The latch on the Lockey 1600 is field-adjustable for backset, so the same lock drops into either of the two standard cylindrical preps without swapping parts or ordering a specific backset. That is the practical reason it suits a mixed building where the doors were prepped by different crews over the years.
3) Do I need to specify handing when I order a Lockey keyless knob lock?
No. Handing on the 1600 is changed in the field, so one lock covers a left-hand or a right-hand door with nothing extra to buy. For a property manager stocking spares that means a single shelf item instead of two.
4) What is the difference between single combination and double combination on the Lockey 1600?
That is the order decision you have to make on this lock. Single combination gives one code for everyone who uses the door. Double combination lets you set two separate codes, which is how you separate two groups of users on the same opening, say a tenant code and a maintenance code. Each comes in all three finishes: Jet Black, Marine Grade, and Oil-Rubbed Bronze.
5) What should I use instead of a mechanical push button lock if the facility needs an audit trail?
The Lockey 1600 is a mechanical push button lock with no batteries or electrical connections, so there is no user record. For openings where you need to know who entered and when, the Alarm Lock T3 DL3075 is a Grade 1 electronic cylindrical lock with audit trail and keypad access, and the Alarm Lock Trilogy T2 DL2700 is a Grade 1 standalone electronic cylindrical lock with a digital keypad and 100 user codes that is IC/SFIC compatible. Both are battery powered and require a battery replacement program the 1600 does not.
6) I need a lever instead of a knob for ADA compliance - what is the alternative to the Lockey 1600?
The Lockey 1600 uses a knob, which does not satisfy an ADA lever requirement. The Marks USA 195N is a Grade 1 Survivor Series passage lever lockset described as ADA compliant, and the Marks USA 195RAB is a Grade 1 Survivor Series entry clutched lever lockset. Neither offers combination entry - they are keyed or non-keyed mechanical locksets, so the tradeoff is losing keyless access to gain the lever.
7) Which classroom-rated lock should I specify for a school instead of a mechanical combination lock?
The Lockey 1600 is a commercial mechanical push button lock without a classroom function. For school openings that need a classroom or intruder function, the TownSteel XCE-9000 is a Grade 1 electronic classroom intruder cylindrical lockset with keypad covering 1-3/4 inch to 2 inch doors, the TownSteel FCE-4000 is an RFID electronic intruder classroom cylindrical lockset, and the Schlage XE360M is a Grade 1 wireless tubular lock with a classroom/storeroom function for 1-3/4 inch doors.
8) What lock works on an exterior gate or coastal door where electronics would fail?
The Lockey 1600 is weather resistant for exterior and interior use, is offered in a Marine Grade finish, and runs with no batteries or electrical connections. The electronic cylindrical alternatives in the same size class - the SDC E75 battery-powered keypad lockset and the SDC Electra 7200 solenoid controlled lock running 12/24VDC - both depend on power, and the 7200 needs wiring to the door. For an unpowered exterior opening the mechanical 1600 is the one that does not require a power path.
9) Which keyless lock should I pick if the spec calls for ANSI Grade 1?
The Lockey 1600 is a commercial mechanical push button lock in zinc-plated steel with an adjustable backset. Where a submittal names ANSI Grade 1 outright, the Grade 1 keyless options include the Alarm Lock Trilogy T2 DL2700 for 1-5/8 inch to 1-7/8 inch doors, the TownSteel XCE-2000 electronic keypad lockset for 1-3/4 inch to 2 inch doors, and the Schlage NDEB ENGAGE Series wireless lock for 1-5/8 inch to 2 inch doors.
10) Can I use the Lockey 1600 push button lock on an exterior gate or door?
Yes, it is built for outside as well as inside. The body is zinc-plated steel with Teflon coated stainless steel internals, and the construction is weather resistant. Coastal and wash-down jobs are the reason the Marine Grade finish exists alongside Jet Black and Oil-Rubbed Bronze.
11) Can someone open the Lockey 1600 with a magnet like the old push button locks?
No. The 1600's internal design is magnet-proof, so the bypass trick that works on some mechanical push button locks does not open it. Combined with the fact that there is no cylinder to pick or key to copy, that is the security case for a mechanical keyless lock on a tenant or storage door.
12) How much room does the Lockey 1600 take up on the door face?
The lock measures 7 5/16 x 2 3/16 x 2 13/16 inches (H x W x D). The height is the thing to check: it is a tall escutcheon-style body, not a compact rose, so on a narrow stile aluminum door or a door with a glass light close to the lock edge, measure the flat area above and below the bore before you commit.
13) How does the Lockey 1600 compare to a Grade 1 electronic keypad lock like the Schlage CO-100 or TownSteel XCE-2000?
Different tools. The Lockey 1600 is mechanical, knob style, with an adjustable backset and a 1-1/8 to 2 inch door range, so it goes on a wider spread of doors and needs no power. The Schlage CO-100 is a Grade 1 heavy duty electronic cylindrical lock but is listed for 1-3/4 inch doors only, and the TownSteel XCE-2000 is a Grade 1 heavy duty electronic classroom lockset for 1-3/4 to 2 inch doors. Those give you programmable users and lever operation; the Lockey gives you a door that keeps working when the battery does not.
14) My doors are thicker than 2 inches. Will the Lockey 1600 still work?
Not out of the box, but it is covered. Standard range is 1-1/8 to 2 inches. Above that you add the optional Extension Kit, which carries the lock up to 5 inch doors. Order the kit at the same time as the lock so the installer is not making a second trip.
15) Does a keyless knob lock give a bathroom or bedroom privacy function?
No - the Lockey 1600 works on a push button combination, so anyone with the code can enter and there is no inside thumbturn privacy hold. For a privacy or bed and bath function, the Cal-Royal CAL20 is a Grade 1 extra heavy duty privacy lock covering 1-3/8 inch to 2 inch doors, the Orca Hardware OCL240 is a Grade 2 medium duty privacy cylindrical lockset, and the Schlage CO-100 is a Grade 1 heavy duty privacy function keypad lock for 1-3/4 inch doors.
16) Is a keypad lock the same as a smart lock for a rental property?
They are not the same. The Lockey 1600 is a mechanical keyless knob lock with a single or double combination and no electronics, so a code change is done at the door. A Kwikset 912TNL ZW500 SmartCode electronic Tustin lever uses Z-Wave technology and is keyed on one side, and the CENTRIOS CEB100 is a Grade 1 smart Bluetooth cylindrical lock. Those two allow code management from a phone or hub; the 1600 does not connect to anything and has nothing to pair or lose signal.
17) What is the closest keyed knob lockset if the tenants will not use a combination?
The Lockey 1600 is a knob-style keyless lock with push button combination entry. If the opening needs a key instead, the Marks USA 110AB is an entry knob lockset with a round knob, Grade 2, 2-3/8 inch backset, in satin stainless steel. It keeps the knob trim and entry function but operates on a key rather than a code, so it fits sites that already run a keyway across the building.
18) Can a keyless push button lock replace a storeroom lock on a supply room door?
They control access differently. A storeroom function such as the Marks USA 175RF SFIC keeps the outside trim locked at all times and is released only by a key or interchangeable core, which is Grade 2 with a 2-3/4 inch backset and an ANSI strike. The Lockey 1600 releases on a combination instead, in single or double combination configurations, with a field-adjustable backset. Choose by whether the room should be opened by a code held by many people or by a core you control from a key system.
19) What is the difference between a mechanical push button lock and a standalone electronic keypad lock?
Both open on a code at the door with no key required. The Lockey 1600 does it mechanically in zinc-plated steel with Teflon coated stainless interior components, with one or two combinations set at the lock. Standalone electronic keypad locks hold many codes in software - the Alarm Lock Trilogy T2 DL2700 is a Grade 1 standalone electronic cylindrical lock with 100 user codes, the Alarm Lock DL5200 is a double-sided electronic cylindrical lock with 100 user capacity and battery operation, and the BEST 9KZ EZ Series adds a key override function. The choice is between per-user code management and a lock with no power source to maintain.
20) I need code entry on both sides of the door - is the Lockey 1600 double combination the same thing?
No. On the Lockey 1600, double combination refers to a second combination option on the lock, offered alongside a single combination version in Jet Black, Oil-Rubbed Bronze, and Marine Grade. If the requirement is a keypad on each face of the door, the Alarm Lock DL5200 is a double-sided electronic cylindrical lock with 100 user capacity and battery operation, sized for 1-5/8 inch to 1-7/8 inch doors.
21) Can I standardize a building on one keyless lock across doors of different thicknesses?
The Lockey 1600 has the widest door thickness coverage of the keyless group at 1-1/8 inch to 2 inch, expandable up to 5 inch with an optional Extension Kit, with a field-adjustable backset and field-reversible handing. Fixed-thickness peers force a second SKU when a door differs - the Schlage CO-100 and TownSteel FCE-2000 are both listed for 1-3/4 inch doors only, and the Schlage XE360M likewise. For a mixed-door fleet, the 1600 reduces how many part numbers the standard needs.
22) What keyed entry lockset matches a 1-3/8 inch to 2-1/4 inch commercial door if the keyless option will not work?
The Lockey 1600 tops out at 2 inch on a standard install. For thicker commercial doors on a key system, the Dorma C150 is a Grade 1 heavy-duty cylindrical lock with an entry/office function covering 1-3/8 inch to 2-1/4 inch, and the Dorma C853 is a Grade 1 single cylinder keyed entry lever covering the same 1-3/8 inch to 2-1/4 inch range.
23) Is the Lockey 1600 rated for a high traffic commercial door or is it a residential lock?
It is classified commercial, and the build reflects it: zinc-plated steel body with Teflon coated stainless steel internals for high-traffic use. Typical placements are office buildings, schools, healthcare, retail, warehouses, multi-tenant residential, and municipal buildings.
24) What is a simpler alternative if the door only needs to latch and not lock?
The Lockey 1600 controls access with a combination. When an opening only needs a latch with no access control at all, the Cal-Royal CAL30 is a Grade 1 extra heavy duty passage lockset for 1-3/8 inch to 2 inch doors, and the Orca Hardware OCL210 is a Grade 2 medium duty passage cylindrical lockset. For trim with no latch mechanism at all, the Dorma C501 is a single dummy keyless lever for 1-3/8 inch to 1-3/4 inch doors.
