Accentra AU-NTB633-NR-626 – Frequently Asked Questions

1) Does the Accentra nexTouch NTB633 have a key override if the batteries die or a code is forgotten?
No. The NTB633 is configured non-keyed, with no cylinder override, so the keypad is the only way in. If your facility needs a mechanical key bypass on that opening, this is the wrong configuration. Where a key override matters, the BEST 9KZ EZ Series electronic keypad cylindrical lock is built with a key override function, and the Lockey E985 keypad lever lock includes key override as well. On the NTB633 itself, a 9V battery backup terminal and a low battery indicator are built in, so a dying battery is signaled rather than discovered at the door.
2) Will the nexTouch NTB633 keypad lock fit a 1-3/4 inch door?
Yes, 1-3/4 inches is the standard door thickness for the NTB633, and thicknesses up to 3-1/4 inches are available to order. That upper range is unusually wide for an electronic cylindrical lock: most keypad cylindrical locks stop around 2 inches, so on a thick door the NTB633 is one of the few that can be ordered to suit. Note it is a 2-3/4 inch backset lock, so the existing cross bore has to be 2-3/4 inches from the door edge or the door needs re-prepping.
3) Will the NTB633 latch into the strike that is already in my frame?
The latchbolt throws 3/4 inch in stainless steel, and the lock ships with a 1-1/4 inch curved lip strike sized for a 1-3/4 inch door. Other lip lengths are available to special order, and all strikes are reversible. If your frame carries a standard ANSI strike prep the curved lip strike will not drop into it, so specify the lip length you need with the order rather than reusing the old strike.
4) Is the NTB633 handed, or can I use the same lock on left and right hand doors?
Handing is field reversible on the NTB633, so one part number covers both hands and you can flip it on site. The front is a free-floating bevel that adjusts from flat to the standard 1/8 inch in 2 inch bevel, which means the same latch works on a flat-edge or beveled door edge without swapping parts. For a property manager stocking spares across a building, that is one lock on the shelf instead of two.
5) Can I install and program an Accentra nexTouch keypad lock myself?
Mechanical installation is a standard cylindrical prep, but the system configuration and programming on the nexTouch NTB633 has to be done by a Yale Accentra Certified Integrator. Plan the labor accordingly: a contractor can hang the lock, but the credential setup is not a self-serve step. If you need a standalone keypad lock you program yourself at the door, the Alarm Lock Trilogy T2 DL2700 is a standalone electronic cylindrical lock with a digital keypad and 100 user codes.
6) Is the nexTouch NTB633 approved for a fire rated door?
Fire rated, UL and cUL listed up to 3 hours, and certified to ANSI/BHMA A156.13 Series 1000 Grade 1. It is also windstorm certified, subject to your local code. That combination is what a healthcare, school, or government spec typically calls for on a stairwell or corridor opening, and it is why the lock carries a stainless steel mechanism rather than a lighter residential-grade one.
7) Can I put the NTB633 on a door that is only 1-5/8 inches thick?
No. The NTB633 is built for 1-3/4 inch doors as standard, with thicker doors available to order, so a thinner leaf is outside what it covers. For a 1-5/8 inch door, the Alarm Lock Trilogy T2 DL2700 and the Trilogy 4100 both cover 1-5/8 to 1-7/8 inches, and the Kwikset 912TNL SmartCode lever covers 1-3/8 to 2 inches.
8) What is a straight equivalent to the Accentra nexTouch NTB633 keypad cylindrical lock from another manufacturer?
The closest peers are Grade 1 standalone electronic cylindrical locks that grant access from a keypad at the door. The TownSteel XCE-2000 Series is a Grade 1 electronic cylindrical lockset with keypad in a classroom function, fitting doors 1-3/4 inch to 2 inch. The SDC E75 Series is a battery-powered electronic cylindrical lockset with keypad access control for doors 1-3/4 inch to 2-1/8 inch. The Alarm Lock Trilogy T2 DL2700 is a Grade 1 standalone electronic cylindrical lock with digital keypad and 100 user codes for doors 1-5/8 inch to 1-7/8 inch. The NTB633 differs from all three in one respect worth confirming before you substitute: it is built non-keyed, with no cylinder override, so keypad entry is the only way in.
9) I need a keypad lock but the door has to keep a mechanical key override - what do I use instead of the NTB633?
The NTB633 is configured non-keyed, so there is no key bypass on it. For an opening that must retain a mechanical override, the BEST 9KZ EZ Series is an electronic keypad cylindrical lock with a key override function, and the Lockey E985 is an electronic keypad lever lock with remote control and key override, for doors 1 3/8 inch to 1 3/4 inch. Both keep a cylinder in the assembly so an authorized key still opens the door if the electronics or batteries are down.
10) Our door is 1-3/4 inch but we have a few thicker doors in the building - which electronic locks cover the range?
The NTB633 is 1-3/4 inch standard with up to 3-1/4 inch available to order, which is the widest reach in the keypad group. Among the electronic peers, the SDC E75 Series covers 1-3/4 inch to 2-1/8 inch, the TownSteel XCE-2000 and XCE-9000 Series each cover 1-3/4 inch to 2 inch, the Schlage NDEB covers 1-5/8 inch to 2 inch, and the Schlage CO-100 keypad lock is 1-3/4 inch. The Alarm Lock Trilogy T2 DL2700 and Trilogy 4100 are 1-5/8 inch to 1-7/8 inch, so they will not take a 2 inch leaf.
11) We want credentials on a phone or card rather than a punched code - what replaces the NTB633?
The NTB633 reads a pushbutton keypad. If the credential needs to be a phone or card instead, the Schlage NDEB is a Grade 1 ENGAGE Series cylindrical lock with a 2.4 GHz Bluetooth Low Energy mobile-enabled reader for doors 1-5/8 inch to 2 inch, the Schlage XE360M is a Grade 1 wireless tubular lock with a smart mobile reader at 1-3/4 inch, and the TownSteel FCE-2000 Series is a Grade 1 standalone motorized cylindrical lockset with RFID at 1-3/4 inch. The CENTRIOS CEB100 is a Grade 1 smart Bluetooth cylindrical lock in a privacy function.
12) We are specifying a school opening that needs classroom intruder lockdown - is the NTB633 the right lock?
The NTB633 is a Grade 1 keypad lock without a deadbolt or cylinder override, suited to office entry, multi-family common areas, and general facility access control. For a lockdown-capable classroom opening, the TownSteel XCE-9000 Series is a Grade 1 electronic classroom intruder cylindrical lockset with keypad for doors 1-3/4 inch to 2 inch, and the TownSteel FCE-4000 Series is an RFID electronic intruder classroom lockset at 1-3/4 inch. The Schlage XE360M carries a classroom/storeroom function with an offline push button.
13) The door is on an access control system with a card reader elsewhere - do I still need a keypad lock like the NTB633?
Not necessarily. The NTB633 is a standalone keypad lock: the credential is entered at the door. If the release decision is made by a panel and the lock only needs to be energized, the SDC Electra 7200 Series is a solenoid controlled cylindrical lock running dual voltage 12/24VDC for doors 1-3/4 inch to 2 inch, with no reader in the lock at all.
14) The opening needs a keyed cylinder for a master key system rather than codes - what should I order?
The NTB633 is built non-keyed. For an opening that has to sit in a key system, the Dorma C853 is a Grade 1 entry keyed single cylinder lever lockset for doors 1-3/8 inch to 2-1/4 inch, the Marks USA 175RF SFIC is a Grade 2 storeroom clutched lever prepped for a small format interchangeable core with a 2-3/4 inch backset and ANSI strike, and the Orca OCL250 is a Grade 2 entrance cylindrical lockset. The 175RF shares the NTB633's 2-3/4 inch backset.
15) What do I have to specify when ordering an Accentra nexTouch NTB633?
Two choices build the part: lever style and finish. Lever styles are Augusta (AU), Monroe (MO), and Pacific Beach (PB). Finishes are 605 Bright Brass, 613E Dark Oxidized Satin Bronze, 626 Satin Chrome, and BSP Black Suede Powder Coat, and every finish is offered on all three levers. Beyond that, call out door thickness if the opening is over 1-3/4 inches and the strike lip length if your frame needs something other than the standard 1-1/4 inch curved lip.
16) What is the difference between the nexTouch NTB633 and a keypad lock with a deadbolt or key override?
The NTB633 is the stripped configuration in the nexTouch keypad line: latch only, no deadbolt, and no cylinder. Everything happens through the keypad. That suits multi-family common areas, office interiors, and secure rooms where you want code-controlled access and no keys circulating. If the opening needs a separate deadbolt throw or a mechanical bypass, a different nexTouch configuration is the one to order, not this one.
17) What else could I use instead of the Accentra nexTouch NTB633 on a 1-3/4 inch commercial door?
Several Grade 1 electronic cylindrical locks cover the same opening. The TownSteel XCE-2000 Series is a keypad electronic cylindrical lockset rated Grade 1 for 1-3/4 to 2 inch doors with a classroom function. The SDC E75 Series is battery powered with keypad access for 1-3/4 to 2-1/8 inch doors. The Schlage CO-100 is a Grade 1 standalone keypad lock built for 1-3/4 inch doors. If you want a credential reader rather than a keypad, the Schlage NDEB ENGAGE Series is a Grade 1 Bluetooth cylindrical lock for 1-5/8 to 2 inch doors. None of those match the NTB633's up-to-3-1/4-inch thickness option.
18) Will an Accentra nexTouch keypad lock hold up on an exterior or unheated entry?
The nexTouch NTB633 is built with a weather resistant seal at the keypad and a stainless steel mechanism and latchbolt, and it carries windstorm certification subject to local code. That is the exterior-duty package on a Grade 1 cylindrical lock. Battery power is backed by a 9V terminal with low battery indication, so a cold-weather battery drop is flagged before it strands anyone outside.
19) Can I lock out codes on an Accentra nexTouch NTB633 during a lockdown?
The NTB633 has a lockout mode built in, along with a deadlocking latch function that resists carding at the latch. Combined with the keypad-only configuration, a lockdown means no valid code opens the door and there is no key cylinder to defeat. Programming who and what is affected is set up by the certified integrator. If you specifically need a classroom intruder function with an inside-controlled lockdown, the TownSteel XCE-9000 Series and the FCE-4000 Series are Grade 1 classroom intruder cylindrical locksets.
20) What is a simpler keyless option if we do not want batteries or electronics on the door?
For keyless entry without any electronics, the Lockey 1600 is a heavy duty mechanical keyless knob lock with adjustable backset, and the Lockey 2830 is a mechanical pushbutton keyless knob lock with an auto-locking passage function. Both fit doors 1-1/8 inch to 2 inch. They are code entry the same way, but the code is set mechanically inside the lock rather than programmed - the NTB633 is an electronic lock and requires a Yale Accentra Certified Integrator to configure and program it.
21) Is the Schlage CO-100 keypad lock a drop-in for the NTB633?
They are both Grade 1 heavy duty electronic cylindrical keypad locks, but the function is not the same. The Schlage CO-100 listed here is a privacy function lock for a 1-3/4 inch door - privacy is an inside-locking function for a restroom or similar opening. The NTB633 is a commercial access control lock with no deadbolt and no cylinder override, granting entry from the keypad only. Confirm the door function before treating one as the other.
22) Which Grade 1 mechanical lockset matches the NTB633 on the non-secured doors of the same job?
The NTB633 carries ANSI/BHMA A156.13 Series 1000 Grade 1. To hold Grade 1 on openings that do not need credentials, the Marks USA 195N Survivor Series is a Grade 1 ADA compliant passage lever lockset, the Marks USA 195RAB is a Grade 1 Survivor Series entry clutched lever, the Dorma C150 is a Grade 1 heavy-duty cylindrical lock in entry/office function for doors 1-3/8 inch to 2-1/4 inch, and the Cal-Royal CAL30 Calypso is a Grade 1 extra heavy duty passage lock for 1-3/8 inch to 2 inch.
23) Can I use the Kwikset SmartCode 912TNL in place of the NTB633 on a commercial opening?
They read differently and are built for different duty. The Kwikset 912TNL ZW500 SmartCode is a Z-Wave electronic Tustin lever, keyed one side, for doors 1-3/8 inch to 2 inch - a home automation credential path. The NTB633 is specified for commercial use, carries ANSI/BHMA A156.13 Series 1000 Grade 1 and UL/cUL fire rating up to 3 hours, and is non-keyed. If the opening is a rated commercial door, check the fire label requirement before considering the SmartCode.
24) What looks like a keypad lock substitute but will not secure the door?
Dummy and half dummy trim is the common mistake. The Dorma C501 is a single dummy trim keyless lever lockset for doors 1-3/8 inch to 1-3/4 inch, the Dorma CL701 is a Grade 2 single dummy non-keyed lever, and the Orca OCL2170 is a Grade 2 half dummy lever. All three are non-keyed like the NTB633, but they carry no latch mechanism and do not control access - they are pull trim. Passage sets such as the Orca OCL210 latch the door but never lock it.
25) We need an audit trail of who opened the door - which keypad locks record entries?
The Alarm Lock T3 DL3075 is an electronic cylindrical lock with audit trail and keypad access, Grade 1, in the DL3200 Series. The Alarm Lock Trilogy T2 DL2700 holds 100 user codes and is IC/SFIC compatible, and the DL5200 is a double-sided electronic cylindrical lock with 100 user capacity on battery power for doors 1-5/8 inch to 1-7/8 inch. The NTB633 is programmed through a Yale Accentra Certified Integrator, so the reporting available to you depends on how the integrator configures the system.
