Kwikset 660M-SMT-KA6-CP Mobile Home Round Single Cylinder Deadbolt, 2-3/8" Backset Round Drive-In Bolt, Round Corner Strike, In Clear Pack

A drive-in bolt has a round collar that taps straight into the bored edge hole, so there is no rectangular faceplate to chisel out. The 660M mobile home deadbolt ships with that round drive-in latch, which is why it suits metal-edged and thin mobile home doors where routing a square face plate is awkward. If your existing door is already mortised for a square-face latch, the round drive-in collar will leave that cutout exposed.

The strike is included. The 660M ships with the deadbolt, the latch, the round corner strike, keys and screws, so the only thing you supply is a screwdriver. The round corner strike matches the rounded strike cutouts typical of mobile home jambs; if your frame is prepped for a square corner strike, plan on a different strike or some filing.

Yes, that is the point of SmartKey. You rekey the cylinder in seconds with the learn tool and a working key, without pulling the lock off the door. For a property manager standardizing units, that means one key can be made to operate this deadbolt and any other Kwikset SmartKey lock on the same keyway, and you can reset a unit after a tenant turns over instead of replacing hardware.

The 660M is single cylinder: key on the outside, thumbturn on the inside. That is what most codes and most landlords want on a unit door, because occupants can get out by hand. If you specifically need key operation on both sides, this is not it, and a double cylinder option such as the Callan Model 210S or the Dexter DB2000 double cylinder is the type to look at instead.

No. The 660 is a residential deadbolt aimed at mobile home and house entry doors. For a commercial opening where a graded lock is specified, look at a Grade 1 or Grade 2 commercial deadbolt instead, for example the Accentra D111 Grade 1 or the Arrow DBX61 Grade 2, both cylinder by thumbturn like this one.

The Kwikset 660M is a residential single cylinder deadbolt keyed outside with a thumbturn inside. For a commercial-rated substitute with the same cylinder x thumbturn function, the Accentra D111 is a Grade 1 single cylinder deadbolt with a 2-3/8 inch backset and a 1-3/8 to 1-3/4 inch door thickness range, and the Dexter DB1000-SCT is a Grade 1 cylinder x thumbturn deadbolt covering 1-3/8 to 1-7/8 inch doors. Both drop the SmartKey re-keying feature in exchange for an ANSI grade.

The Kwikset 660M is single cylinder only, key outside and thumbturn inside. For a double cylinder opening, keyed on both faces, the Dexter DB2000-DCT is a Grade 2 double cylinder deadbolt for 1-3/8 to 1-3/4 inch doors, the Hager 3214 is a Grade 2 double cylinder deadbolt with a Schlage C keyway for the same thickness range, and the Design Hardware D1 Series is a Grade 1 extra heavy duty double cylinder deadbolt for 1-3/4 inch doors. Verify local egress code before specifying a double cylinder on a dwelling unit exit.

The Hager 3215 is a Grade 2 single cylinder deadbolt with a 1 inch throw and a fire rating, for 1-3/8 to 1-3/4 inch doors, and the Hager 3118 is a Grade 1 classroom deadbolt with a Schlage C keyway, 6-pin cylinder and a fire rating over the same thickness range. The Cal-Royal CRB800 is a Grade 1 heavy duty single cylinder deadbolt with a UL 3-hour fire rated latch.

The Kwikset 660M uses SmartKey re-keying rather than an interchangeable core. For an SFIC system, 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 inch doors, the Deltana CL200LAIC is a Grade 2 single cylinder interchangeable core deadbolt with a 2-3/4 inch backset, and the Delaney LM Series 301702 is a Grade 1 single cylinder less core deadbolt in dull chrome US26D.

The Kwikset 660M is built for a 2-3/8 inch backset with a round drive-in bolt. For a 2-3/4 inch backset, the Deltana CL200LA is a Grade 2 single cylinder deadbolt with a 2-3/4 inch backset. Where the backset is uncertain, the Cal-Royal ED500 is a Grade 3 single cylinder deadbolt with an adjustable backset for 1-3/8 to 1-3/4 inch doors, and the Falcon D111 is a Grade 1 classroom deadbolt with an adjustable backset.

The 660M-SMT-KA6-CP is supplied keyed alike under the KA6 key group, so locks ordered in that group operate on the same key. Being SmartKey, it can also be rekeyed on site to whatever key you are already carrying rather than forcing the building onto a new one.

The 660M is a fixed 2-3/8 inch backset. If you are buying blind for a mixed portfolio of doors, an adjustable-backset deadbolt is the safer order, such as the Brinks Raleigh with its 4 way adjustable backset or the Cal-Royal ED500, which has an adjustable backset and covers 1-3/8 to 1-3/4 inch doors.

For thicker doors, the Deltana 7312KA2 covers 1-3/8 to 2 inch doors as a Grade 3 double cylinder deadbolt, and the Corbin Russwin DL3011 cylindrical deadlock covers 1-3/4 to 2-1/4 inch doors. Both are options when the opening falls outside a standard residential mobile home door.

The Kwikset 660M is a round trim single cylinder deadbolt whose distinguishing feature is SmartKey re-keying. Without that feature, the Bravura 310B Elite is a Grade 2 traditional round deadbolt, cylinder x thumbturn, the Callan 200S-G2 is a Grade 2 single cylinder round trim deadbolt, and the Brinks Raleigh E2401 is a transitional round single cylinder deadbolt with a 4-way adjustable backset for openings where the backset is not confirmed.

No. The Kwikset 660M is a complete single cylinder deadbolt supplied with latch, strike, keys and screws. The Arrow 460 is a mortise lock strike for latchbolt and deadbolt functions with a straight lip, and the BEST 8T is a tubular deadbolt tube component from the T Series. Those are parts that serve an existing lock, not a standalone deadbolt for an unprepped door. The Baldwin 8BR0618001 is likewise a deadbolt spacer, not a lock.

The Kwikset 660M is mechanical, operated by key outside and thumbturn inside. For electronic control in a deadbolt footprint, the Delaney KP400 is a Grade 2 electronic deadbolt with a programmable remote, the Codelocks CL2200 is an electronic surface deadbolt in brushed steel, and the Dormakaba Saffire LX-D is an RFID electronic deadbolt with BLE and electronic lock override.

The Cal-Royal LSD is a Grade 3 single cylinder deadbolt with an ADA ergonomic thumbturn, cylinder x thumbturn function, for 1-3/8 to 1-3/4 inch doors. It is worth specifying over a standard turn piece where residents have limited hand strength.

The Kwikset 660M is keyed from the outside with a thumbturn inside, so it secures an exterior entry. The Arrow E60 is a Grade 2 exit deadlock that is non-keyed, with a blank plate outside and a thumbturn inside for 1-3/8 to 1-3/4 inch doors - it locks only from within and cannot be opened by key from the exterior. Use the E60 where no outside access is wanted, not as a substitute on a tenant entry door.

All of these keep the cylinder x thumbturn function. The Arrow DBX61 is a Grade 2 single cylinder deadbolt, the Cal-Royal CB160 is a Grade 2 single cylinder deadbolt with a tamper-resistant cylinder guard, the Falcon D211 is a Grade 2 medium duty deadbolt, and the Deltana CL200LM is a Grade 1 single cylinder deadbolt. The CB160 cylinder guard is the one to look at for doors that have seen attack attempts.

Two: satin chrome and polished brass. Satin chrome is the usual match for brushed nickel and stainless entry sets on newer units, polished brass for older bright brass hardware. Pick by what is already on the entry knob so the door reads as one set.

Yes, assuming the door is already bored. The 660M mounts with a screwdriver, and the drive-in bolt drops into the edge hole with no faceplate mortise, so a tech can swap a failed deadbolt on a turnover in a few minutes. It arrives in a clear pack, which is convenient if you are staging hardware by unit.
