Dormakaba 5021-XS-WL-26D-41 – Frequently Asked Questions
1) Will the Dormakaba Simplex 5021 fit a standard 161 prep, or do I have to drill the door again?
The Simplex 502x cylindrical lock goes into an ASA 161 prep, but it needs additional through holes beyond a plain 161 bore, so a door already prepped for a standard cylindrical lockset will need those extra holes drilled. It mounts on wood or metal doors, and a full scale template comes in the box along with the lock assembly, installation manual and required hardware. Door thickness range is 1-3/8 to 2-1/4 inches, and the door or stile needs at least 5 inches of width.
2) Which backset do I order on the Simplex 5021 vs 5022 vs 5025?
Backset is what separates the three models. The 5021 is 2-3/4 inch backset with a 1/2 inch throw latch, and that is the standard commercial pick. The 5022 is 2-3/8 inch backset with a 1/2 inch throw, for doors bored on the shorter backset common on lighter and older openings. The 5025 keeps the 2-3/4 inch backset but carries a 3/4 inch throw latch. Measure from the door edge to the center of the bore before you order, because the backset is not field adjustable on these.
3) Do I need to specify handing on the Dormakaba Simplex 502x pushbutton lock?
No handing to specify. The Simplex 502x is non-handed. It ships pre-assembled for a left hand door and converts to right hand in the field, so one part number covers both swings. For a property manager stocking spares across a building, that means a single SKU on the shelf regardless of which way the door swings.
4) Can I put this Simplex lock on my existing keyway so it works with our master key system?
Yes, and the cylinder choice is how you do it. Two options come with a cylinder in the box: XS on Schlage C keyway and XK on Kaba 90 keyway. The rest are prepped less core so your locksmith drops in the core you already use: B for 6/7-pin SFIC (Best and equivalents), C for Corbin Russwin 6-pin LFIC, M for Medeco/Yale/ASSA/Abloy LFIC, R for Sargent LFIC, and S for Schlage FSIC. If the building is already on a master system, order the prep that matches your core and supply the core yourself.
5) Does the Simplex 502x need batteries or wiring?
Neither. The Simplex 502x is fully mechanical and battery free, with a direct drive design, so there is no power to run, no battery to change on a maintenance schedule, and no dead lock when the power drops. Access is by a single pushbutton code with key override, and egress from the inside is free at all times. For a remote gate house, a storage building, or any opening you do not want to trench power to, that is the reason to pick a Simplex over an electronic keypad.
6) Is the Dormakaba Simplex 5021 fire rated and ADA compliant for a commercial corridor?
Grade 1 under ANSI/BHMA, ADA compliant with the Winston lever, and 3-hour UL/ULC fire rated for A label doors. It is also DOD 5220.22M compliant for supplemental access control, which matters on government and defense contractor work. The lever operation is what satisfies ADA here, so it works on the accessible routes a knob would fail.
7) Will a Simplex 502x work on a narrow aluminum storefront door?
Probably not. This is a cylindrical bored lock needing a minimum 5 inch stile, and most narrow stile aluminum entrances run well under that. For a glass front opening you want a narrow stile device, not a bored lockset. On a wide stile aluminum door, a hollow metal door, or a wood door with 5 inches or more of stile and a thickness between 1-3/8 and 2-1/4 inches, the 502x installs without trouble.
8) How do you change the code on a Simplex 5021, and can I have more than one code?
The combination is changed at the exterior keypad without pulling the lock off the door, so you can rotate the code after a tenant or a contractor leaves without a service call. There is one access code at a time, managed entirely from the keypad, so this is not the lock to use if you need separate codes per user or an audit trail. The key override still gets staff in independently of whatever the code is set to.
9) Can a Simplex pushbutton lock go on an exterior door?
Yes. The 502x is weather resistant and rated for indoor and outdoor applications, with vandal resistant metal pushbuttons rather than plastic ones. Body material is brass or bronze. For an exterior opening, the 744 Dark Bronze with Brass Accents or 626 Satin Chrome are the usual picks over the polished 605 Bright Brass, which shows wear faster on a high traffic entrance.
10) If I buy several Simplex locks for one building, can they all take the same key?
Keying is a choice at order time on the models that ship with a cylinder (XS Schlage C and XK Kaba 90): no special keying, keyed alike, or keyed different. Keyed alike only does anything if you are buying more than one lock on the order. If you picked one of the less core preps (B, C, M, R or S), keying is handled by whatever core your locksmith installs, not by this selection.
11) Should I use the Simplex 502x or a 503x, 504x or 505x?
The 502x is combination entry with key override, one code, changed from the exterior keypad. Step up the series when you need more: the 504x adds a passage function, so the lock can be held unlocked for business hours, and the 505x adds interior combination change. If you only need one code on a door that stays locked with key override for staff, the 502x is the right one and the rest is capability you will not use.
12) What do I get in the box with a Simplex 5021, and what do I still need to buy?
The carton has the lock assembly (outside unit, inside unit, latch and ASA strike), mounting screws, set screw, Allen wrench, combination change tool, the installation manual and a full scale template. What is not included depends on the cylinder option: order B, C, M, R or S and the lock arrives less core, so you supply the interchangeable core. Order XS or XK and the conventional cylinder is in the box.
13) What finishes does the Simplex 502x with Winston lever come in?
Four finishes: 605 Bright Brass, 606 Satin Brass, 626 Satin Chrome, and 744 Dark Bronze with Brass Accents. 626 is the one that matches most existing commercial hardware in a building already standardized on satin chrome, and 744 is the darker option for bronze exterior packages. That is the complete finish range, so if the building runs oil rubbed bronze or black, this lock will not match it exactly.
