Emtek 6621-FB – Frequently Asked Questions
1) What door prep does the Emtek 6621 keyed sideplate lockset need, and can it go into an existing bored door?
It drops into a standard 2-1/8 inch cross bore, which is the same prep almost every residential bored lockset uses. Backset is adjustable between 2-3/8 and 2-3/4 inches, so an existing bore at either of the two common backsets works. What it does not do is reuse the old face prep alone: the sideplate is a long escutcheon at 5-1/2 inches center to center between the knob or lever and the key cylinder, so the plate needs a clean face and the second bore for the cylinder.
2) Is the Emtek 6621 a double cylinder lock, and does it take a key on the inside too?
Yes, it is double keyed. The 6621 is an entry function with a double cylinder, meaning a key operates it from both the outside and the inside rather than a thumbturn indoors. That is the setup people choose for a door with glass beside or in it, since there is no turn piece to reach through for. It also means anyone inside needs a key to get out, so check your local egress rules for the opening before you commit.
3) Do I have to specify handing when I order an Emtek Tuscany sideplate lockset?
Handing is required, right hand or left hand, on every order of the 6621. That is true regardless of which inside trim you pick, and it is called out specifically for leversets since a lever has to point toward the latch edge. Stand outside the door: if the hinges are on your right it is right hand.
4) Can the Omnia D12036PD be used in place of the Emtek 6621 on a exterior entry door?
No. Despite matching the 5-1/2 inch center-to-center spacing and the sideplate appearance, the Omnia D12036PD is a double dummy, meaning it has no working latch or cylinder and is surface trim only. The Emtek 6621 is a keyed entry lockset with a double cylinder function. For an entry opening the working equivalents are the Omnia D12036AC in double cylinder or the D12036A in single cylinder.
5) What is the difference between the Emtek 6621 Tuscany sideplate lockset and the Omnia D12036AC?
Both are double cylinder sideplate designs at the same 5-1/2 inch center-to-center spacing. The Emtek 6621 is a Tuscany series lost wax cast bronze tubular set with a double cylinder keyed function, ordered with your choice of Tuscany knob or lever for the inside trim. The Omnia D12036AC is a double cylinder deadbolt lever lockset in solid brass with a sideplate design, and comes as a lever set. So the decision is bronze with a knob-or-lever choice versus solid brass in a lever configuration.
6) I need a keyed sideplate set but code says no double cylinder on my egress door. What should I use instead of the Emtek 6621?
The Emtek 6621 is a double cylinder keyed function, meaning it takes a key on both sides. Where a single cylinder is required so the inside can be operated without a key, the Omnia D12036A is a single cylinder deadbolt lever lockset in solid brass. It keeps the keyed sideplate concept and moves the inside to a thumbturn-style operation rather than a second cylinder.
7) Can I key several Emtek Tuscany sideplate locksets alike so one key runs the whole house?
Yes. Keying is a required selection on the 6621, and you choose keyed different or keyed alike at no charge. There is also a keying to code field, so if the property already runs a code you can enter it and have the new locks cut to match the keys in circulation instead of rekeying later.
8) Is the Emtek 6621 Tuscany lockset solid bronze, and is it suitable for a commercial building?
The 6621 is lost wax cast bronze, a solid bronze substrate rather than a plated finish over a lighter base, in Flat Black Bronze or Medium Bronze. It is a residential-rated lockset. For an apartment corridor, an office, or anything on a commercial occupancy schedule with grade requirements, this is not the part to spec.
9) Should I use a sideplate lockset like the Emtek 6621 or a separate knob and deadbolt?
A sideplate lock puts the handle and the key cylinder on one continuous escutcheon, 5-1/2 inches between centers, so the door face reads as one piece of hardware instead of two. Functionally the 6621 is a tubular bored lock with the latch doing the securing, not a separate deadbolt. If you want a deadbolt behind the sideplate look, the Omnia D12036AC is a double cylinder deadbolt lever lockset with a sideplate design, and the D12036A is the same idea single cylinder with a thumbturn inside.
10) I want a matching sideplate on a closet or French door that does not lock. What do I use with the Emtek 6621?
The 6621 is a keyed entry lock, so it is the wrong part for a non-latching opening. For the inactive leaf of a pair or a closet door where the trim just needs to match, the Omnia D12036PD is a double dummy sideplate lever lockset at the same 5-1/2 inch center to center, so the plate geometry lines up with the working door.
11) Will the Emtek 6621 latch faceplate match my existing mortised latch pocket, round corner or square?
Both faceplate profiles are available on the 6621 latch, round corner and square corner. Match whichever is already routed into the door edge and you avoid recutting the pocket. Same applies to the strike: the set includes one, so the frame side is covered.
12) I want knobs, not levers, on a 5-1/2 inch center-to-center sideplate set. Which one works?
The Emtek 6621 Tuscany sideplate lockset at 5-1/2 inch center to center is ordered with your choice of inside trim, including knobs such as the Octagon, Parma, Petal, Georgetown, Old Town, Bristol, Hampton, Lowell and Windsor, plus Ebony and Ice White porcelain, as well as the Medici, Napoli, Octagon and Padua levers. The Omnia D12036A, D12036AC and D12036PD at the same spacing are lever locksets. If the specification calls for a knob on a sideplate, the 6621 is the set that carries it.
13) Is the Emtek 6621 or the Omnia D12036AC the better match for a bronze finish package?
The Emtek 6621 is a lost wax cast bronze set from the Tuscany Bronze collection, offered in Flat Black Bronze and Medium Bronze. The Omnia D12036AC is solid brass construction. If the rest of the openings are running a bronze package, the 6621 keeps the substrate consistent; if the job is standardized on brass, the D12036AC matches that side.
