Dormakaba Simplex EE1011 Double Sided Pushbutton Lock

None of the above. The EE1011 is a fully mechanical pushbutton lock, so there is no wiring to pull, no transformer, and no batteries to change. That makes it a common pick for gates to mechanical rooms, storage, and remote openings where getting power to the door is the expensive part of the job. It also means access does not fail when the building loses power.

Yes, and that is the whole point of the EE1011. It is a double sided pushbutton lock: both sides are combination controlled, and each side takes its own independent code. So it restricts movement in both directions, unlike the single sided Simplex models where the inside lever is free egress. Before specifying it, check your egress requirements with the authority having jurisdiction, because a code required to exit is not acceptable on every opening.

No key cylinder. The EE1011 is a non-keyed lock, so access on both sides is by pushbutton combination only and there is no mechanical key bypass. If your facility needs a master key or a key override for lockout situations, you want a Simplex model ordered with the key override option instead, not this one.

The EE1011 is a cylindrical lockset built for a 2-3/4 inch backset, which is the standard commercial backset on a bored door. If your existing lock is a 2-3/4 inch backset cylindrical lock with a standard 2-1/8 inch cross bore, the prep is the same family of prep. Simplex locks use their own through-bolt and spindle layout, so expect some additional drilling on the door face rather than a pure drop-in.

The latch on the EE1011 has a 1/2 inch throw and ships with a standard strike plate, with an ASA strike plate also available for the lock. A 1/2 inch throw needs the strike lip and the frame prep to be within about that distance of the latch face, so on a door with a worn gap or a heavily painted frame, plan on adjusting the strike rather than assuming the old one lines up. If your frame is prepped for a full ASA (1-1/4 by 4-7/8 inch) cutout, order the ASA strike.

With the ASA strike plate, the assembly carries a 3 hour UL and ULC fire rating for an A labeled door. That covers the heaviest common fire door rating, so it suits stair doors, mechanical rooms, and corridor openings in institutional buildings. Confirm the door and frame label rating matches the opening before you install, and specify the ASA strike when the opening is fire rated.

The EE1011 covers doors from 1-3/4 inches up to 2-1/4 inches thick. That takes in standard 1-3/4 inch commercial doors as well as the thicker exterior and insulated doors you find on mechanical rooms and loading areas. Measure the door edge before ordering, because a thin 1-3/8 inch interior residential door falls below the range.

No handing to specify. The EE1011 is field reversible, so one part number covers left and right hand openings and the handing is set during installation. For a property manager stocking spares across a building, that means a single unit on the shelf covers any door in the fleet rather than keeping both hands on hand.

It is a Grade 1 commercial lockset, which is the heaviest ANSI/BHMA duty level and the one written into most institutional and government specs. That puts it in range for high traffic openings in schools, healthcare, and multi-family common areas rather than light residential use.

The Simplex EE1011 in 626 satin chrome is the current replacement for the EE101126D41. Same double sided combination entry and egress function, mechanical operation, and satin chrome finish.

One finish: 626 satin chrome. If the rest of the openings in the building are on 626 satin chrome lever sets and closers, the EE1011 matches without a special order. Buildings standardized on 630 satin stainless or a bronze finish will see a visible difference at this door.
