Kwikset 780-3S.STRKP – Frequently Asked Questions

1) Will the Kwikset 780 deadbolt fit my existing door prep, or do I need to drill new holes?
The 780's latch has an adjustable backset covering 2-3/8 and 2-3/4 inches, which are the two standard residential bore layouts, so it drops into an existing deadbolt prep without redrilling. Installation takes a screwdriver. The included latch has round corner faceplates, so if the door edge is mortised for a square corner faceplate you would need to pare the mortise corners.
2) Can I key the Kwikset 780 SmartKey deadbolt to match the keys I already carry?
SmartKey re-keying lets you set the 780 to an existing key yourself in seconds, no cylinder removal and no locksmith. It works with either the Kwikset KW1 keyway or the Schlage SC1 keyway, so a property manager replacing bolts across a building can bring the new deadbolts onto the key already in use on either system. Two keys ship with the lock.
3) Does the Kwikset 780 deadbolt have a 1 inch throw, and will it work with my current strike?
One inch throw, and a round deadbolt strike is included in the pack. That 1 inch bolt is what building codes and insurers generally look for on an exterior entry door. If the frame already has a strike with a 1 inch deep pocket, the bolt will seat in it; if the existing strike is shallow or the pocket was cut for a shorter bolt, use the round strike supplied and deepen the frame mortise to take the full inch.
4) Is the Kwikset 780 deadbolt rated for a fire door?
The 780 is UL fire rated, so it can go on a rated opening. It is a residential product carrying ANSI/BHMA Grade 2, which is the top residential grade for security, durability and finish. For a commercial rated opening where the spec calls Grade 1, look at a heavy duty commercial bolt such as the Cal-Royal CRB800 with its UL 3-hour fire rated latch, or the Design Hardware D1 Series.
5) Single cylinder or double cylinder deadbolt, which do I need on a door with glass beside it?
The Kwikset 780 is single cylinder: key on the outside, thumb turn on the inside. That is the right choice almost everywhere, because anyone inside can get out without hunting for a key. If a local ordinance or an insurer requires a keyed cylinder on both faces (often on doors with glass within reach of the bolt), the 780 is not the part; a double cylinder such as the Dexter DB2000 double cylinder, the Callan 210S, or the Baldwin Reserve Contemporary Round is what to specify. Double cylinder bolts are restricted on egress doors in many jurisdictions, so check the code before you order one.
6) What is the closest commercial-grade equivalent to the Kwikset 780 single cylinder deadbolt?
The Kwikset 780 is a Grade 2 single cylinder deadbolt operated by key outside and thumb turn inside, with a 1 inch throw and a latch adjustable from 2-3/8 to 2-3/4 backset. The Hager 3215 is a Grade 2 single cylinder deadbolt with a 1 inch throw in cylinder x thumbturn function, fitting doors 1-3/8 to 1-3/4 thick. The Arrow DBX61 is also a Grade 2 cylinder x thumbturn deadbolt in the DBX series, and the Dexter DB2000 single cylinder is Grade 2 cylinder x thumbturn for 1-3/8 to 1-3/4 doors. All three keep the same key outside, turn inside operation on a standard door prep.
7) Which deadbolt steps up to Grade 1 when a spec calls for heavier duty than the Kwikset 780?
The Kwikset 780 carries ANSI/BHMA Grade 2 certification. Where a drawing calls for Grade 1, the Dexter DB1000 single cylinder is Grade 1 cylinder x thumbturn for doors 1-3/8 to 1-7/8 thick, the Accentra D111 is a Grade 1 single cylinder deadbolt in the D Series with a 2-3/8 backset for 1-3/8 to 1-3/4 doors, and the Falcon D111 is a Grade 1 heavy duty deadbolt in the D100 Series with an adjustable backset. The Deltana CL200LM is another Grade 1 single cylinder deadbolt in cylinder x thumbturn function.
8) What deadbolt should be used instead of the Kwikset 780 on a glass-adjacent or sidelite door where a thumb turn is not wanted?
The Kwikset 780 is a single cylinder deadbolt with a thumb turn on the interior, so it opens from inside without a key. Where the inside turn needs to be replaced by a keyed cylinder, the Hager 3214 is a Grade 2 double cylinder deadbolt for 1-3/8 to 1-3/4 doors, the Dexter DB2000 double cylinder is Grade 2 for the same thickness range, and the Delaney LU Series is a Grade 2 double cylinder deadbolt. Local egress code governs whether double cylinder is permitted on the opening.
9) Which deadbolt uses a Schlage C keyway instead of the Kwikset SmartKey cylinder?
The Kwikset 780 uses SmartKey Security re-key technology, compatible with the Kwikset KW1 keyway or SC1 keyway options, and is re-keyed by the owner in seconds. Where a building is keyed to a Schlage C system, the Hager 3215 single cylinder deadbolt, the Hager 3115 cylinder x thumbturn deadbolt and the Hager 3214 double cylinder deadbolt are all supplied with a Schlage C keyway and fit doors 1-3/8 to 1-3/4 thick.
10) Which deadbolt carries a fire rating comparable to the Kwikset 780 for a rated opening?
The Kwikset 780 is fire rated UL. Among comparable bolts, the Hager 3215, Hager 3115 and Hager 3214 all carry a fire rating and fit doors 1-3/8 to 1-3/4 thick, and the Cal-Royal CRB800 is a Grade 1 heavy duty single cylinder deadbolt with a UL 3-hour fire rated latch. Match the bolt to the label on the door assembly.
11) Is a Grade 2 SmartKey deadbolt enough for an apartment building entry, or do I need Grade 1?
Grade 2 is the top residential rating and the 780 is built to it, which suits unit entry doors on multi-family and single family rentals. Where the door is a shared or main building entrance taking commercial traffic, spec Grade 1 instead: the Accentra D111, the Delaney LM Series less core bolt, the Deltana CL200LM, or the Dexter DB1000 single cylinder are Grade 1 cylinder x thumbturn bolts. The trade-off is re-keying: those need a locksmith or a core swap, while SmartKey lets on-site staff re-key a unit themselves after a tenant turnover.
12) I need a deadbolt for an exterior entry door, is the Kwikset 780 the right type?
Yes for a keyed exterior entry. The 780 is a tubular single cylinder deadbolt meant for exterior doors where keyed entry and security are needed, and it is a standalone bolt, so it goes above a knob or lever, not in place of one. If you want the bolt and the latch tied together so one turn of the inside lever retracts both, an interconnected lock like the Falcon H2101 does that job instead. For a door that only needs to be secured from inside with no key outside, the Arrow E60 blank plate by thumbturn exit deadlock is the part.
13) Does the Kwikset 780 SmartKey protect against lock picking and bumping?
SmartKey Security is the reason to pick the 780 over a standard pin tumbler bolt: it resists advanced break-in techniques, and it is the same mechanism that lets you re-key the cylinder yourself. Paired with the 1 inch bolt throw and Grade 2 certification, that covers the two ways an entry bolt usually gets beaten, at the cylinder and at the frame.
14) Do I need to buy a strike plate and latch separately with the Kwikset 780?
No extras needed for a standard install. The 780 ships as a pack with the 6AL adjustable latch, the STRKP round deadbolt strike, and two keys. All you bring is a screwdriver. The one thing to plan for is the key system: decide up front whether you are re-keying to a KW1 or an SC1 key, since SmartKey handles both and you set it after the lock is mounted.
15) Can I use the Kwikset 780 on a classroom or office door that needs a keyed deadbolt on both sides of the operation?
Not the right tool. The 780 always operates from a thumb turn inside, which is what you want on a dwelling entry but not what a classroom deadlock spec calls for. For those, the Falcon D111 Grade 1 or D211 Grade 2 classroom deadbolts, the Hager 3118 Grade 1 classroom deadbolt with a Schlage C keyway, or the Corbin Russwin DL3011 cylindrical deadlock are the commercial parts to look at.
16) Is a classroom function deadbolt the same as the Kwikset 780 single cylinder deadbolt?
No. The Kwikset 780 is keyed outside with a thumb turn inside, so anyone inside can retract the bolt by hand. Classroom function deadbolts operate differently: the Falcon D211 is a Grade 2 classroom function deadbolt with single cylinder operation in the D200 Series, the Falcon D111 is the Grade 1 classroom version, and the Hager 3118 is a Grade 1 classroom deadbolt with a Schlage C keyway and a 6-pin cylinder for 1-3/8 to 1-3/4 doors. These are specified for institutional openings where the bolt is controlled by key rather than by an inside turn.
17) What is a lighter-duty alternative to the Kwikset 780 for interior or low-traffic doors?
The Kwikset 780 is a Grade 2 deadbolt built for exterior doors where keyed entry and security are needed. For openings that do not call for Grade 2, the Cal-Royal ED500 is a Grade 3 single cylinder deadbolt with an adjustable backset for 1-3/8 to 1-3/4 doors, the Cal-Royal LSD is a Grade 3 single cylinder deadbolt with an ADA ergonomic thumbturn over the same thickness range, and the Callan Model 200S is a Grade 3 single cylinder deadbolt with square trim in cylinder x thumbturn function.
18) What deadbolt takes an interchangeable core instead of the Kwikset 780 fixed cylinder?
The Kwikset 780 comes with two keys and a SmartKey cylinder re-keyed by the owner. Facilities standardized on a small format interchangeable core system use a different bolt: the Arrow E61 26D IC is a Grade 2 single cylinder deadlock with SFIC prep supplied less core for 1-3/8 to 1-3/4 doors, the Deltana CL200LAIC is a Grade 2 single deadbolt prepped for interchangeable core with a 2-3/4 backset, and the Delaney LM Series is a Grade 1 single cylinder less core deadbolt in dull chrome US26D.
19) What should be used in place of the Kwikset 780 on a door with no exterior keyed access?
The Kwikset 780 is keyed on the outside with a thumb turn inside. Where the outside face should carry no cylinder, the Arrow E60 is a Grade 2 exit deadlock, non-keyed, in blank plate x thumbturn function for 1-3/8 to 1-3/4 doors, and the Callan Model 205S is a Grade 3 one-sided half-bore deadbolt. Both throw the bolt from the inside only, so they suit stockroom and service doors that are never entered by key.
20) Is an electronic or keypad deadbolt a drop-in for the Kwikset 780?
The Kwikset 780 is a mechanical deadbolt operated by key outside and thumb turn inside, installed with just a screwdriver. Electronic bolts change how the door is credentialed: the Delaney KP400 is a Grade 2 electronic deadbolt with a programmable remote, the Codelocks CL2210 is an electronic mortise deadbolt, the Codelocks CL2200 is a medium duty electronic surface deadbolt in brushed steel, and the Dormakaba Saffire LX-D is an RFID electronic deadbolt with BLE and electronic lock override. They require power and credential management rather than a key and turn.
21) Does the Kwikset 780 replace a mortise deadbolt?
No. The Kwikset 780 is a bored deadbolt whose latch drops into a standard 2-3/8 to 2-3/4 backset door prep and installs with a screwdriver. A mortise deadbolt needs a pocket cut into the door edge: the Dormakaba D900 is a small case mortise deadbolt with a D cylinder in cylinder x thumbturn function, the Emtek 2050 and 2051 are European mortise deadbolts with an integrated roller latch in square and round trim, and the BEST 8T is a T Series tubular deadbolt tube component rather than a complete lock. Confirm the existing door prep before swapping either way.
22) What is the difference between the Kwikset 780 and a deadbolt with a fixed 2-3/4 backset?
The Kwikset 780 latch adjusts from 2-3/8 to 2-3/4, so one bolt covers either bore center. The Deltana CL200LA is a Grade 2 single deadbolt supplied with a 2-3/4 backset, and the Accentra D111 is a Grade 1 single cylinder deadbolt with a 2-3/8 backset. A fixed-backset bolt has to be ordered to match the hole already in the door, while an adjustable latch is set at install.
23) Is the Baldwin 8BR0618001 or the Arrow 460 a substitute for the Kwikset 780 deadbolt?
Neither is a lock. The Kwikset 780 is a complete single cylinder deadbolt shipped with a 6AL latch, a round deadbolt strike pack and two keys. The Baldwin Reserve 8BR0618001 is a deadbolt spacer for a double cylinder application, and the Arrow 460 is a mortise lock strike with a straight lip for latchbolt and deadbolt functions on a 1-3/4 door. Those are components ordered alongside a lock, not in place of one.
24) What should be specified instead of the Kwikset 780 when the knob or lever and the deadbolt need to work together?
The Kwikset 780 is a standalone deadbolt for a separate bolt bore above the knob prep. Where one device is wanted, the Falcon H2101 is a Grade 2 entrance interconnected lock with a single cylinder deadbolt in the H2 Series, and the Baldwin Estates 8011 is a contemporary 1-5/8 double cylinder deadbolt in entrance function from the Estate Series. An interconnected lock retracts latch and bolt together from the inside lever.
25) What finishes does the Kwikset 780 SmartKey deadbolt come in?
Five finishes: Satin Nickel, Venetian Bronze, Bright Chrome, Bright Brass, and Matte Black. That spread lets you match the 780 to warm brass or bronze trim, to brushed nickel, or to the black hardware common on newer builds, so a landlord standardizing entry doors across a portfolio can keep one lock model and vary only the finish.
26) What deadbolt matches the Kwikset 780 in decorative styling for a residential entry?
The Kwikset 780 is a Signature Series residential deadbolt offered in Venetian Bronze, Satin Nickel, Bright Chrome, Bright Brass and Matte Black. Where a different trim shape is wanted on the same key outside and turn inside function, the Bravura 310B Elite is a Grade 2 traditional round deadbolt, the Bravura 310SC Elite is a Grade 2 contemporary square deadbolt, the Brinks Raleigh Series is a transitional round single cylinder deadbolt with a 4 way adjustable backset, and the Brinks Mendocino Series is the contemporary square equivalent.
