Medeco Maxum Double Cylinder Residential Deadbolt with High-Security Key Control

The Medeco Maxum Double Cylinder Residential Deadbolt delivers industry-leading physical security and key control for demanding residential applications. Featuring the Medeco 4 (M4) patent-pending design, this UL 437 Listed and BHMA A156.5 Grade 1 Certified deadbolt protects against unauthorized key duplication, bumping, picking, drilling, wrenching, and kicking attacks. A solid 1" hardened steel bolt housed in heavy-gauge tubular steel provides maximum resistance to physical attack, and the unit fits doors 1 3/8" to 2 1/2" thick with a standard 2 1/8" crossbore and 1" edge bore (ANSI A115.13 prep).

Key Features

  • High-Security Bolt Construction: Solid 1" hardened steel bolt and bolt-throwing mechanism surrounded by a heavy-gauge tubular steel housing for maximum resistance to crowbar and physical attacks.
  • Door Thickness Compatibility: Fits doors 1 3/8" to 2 1/2" thick with a standard 2 1/8" crossbore and 1" edge bore (ANSI A115.13 prep) for straightforward installation.
  • Medeco 4 (M4) Key Control: Patent-pending key control technology protects against unauthorized duplication of keys, including deterrence against 3D-printed key copies or blanks, ensuring only authorized individuals can duplicate keys.
  • Drill and Pick Resistance: Hardened steel inserts and rotating pins provide drill and pick resistance per UL 437 standard; solid-brass construction with strategically placed drill pins offers maximum protection.
  • Steel Shroud Over Bolt: Steel shroud over the bolt protects against "ice pick" type attacks, adding an additional layer of physical security beyond the bolt itself.
  • High-Security Strike Plate: Special box-design strike plate secured with 2" screws that anchor directly to the building structure behind the frame, preventing kick-in type attacks.
  • Master Keying Capabilities: M4 deadbolts can be master keyed into systems that include M4, M4 BiLevel, and M4 CLIQ keys and cylinders, supporting extremely large master key systems.
  • Special Angle Cut Keys: Requires a special key cutting machine and Medeco-specific blanks; angled cuts plus fore and aft positioning dramatically increase key combinations for large master key systems.
  • Available Finishes: Offered in 14 finishes including Bright Brass (05), Satin Brass (06), Antique Brass (09), Satin Brass Blackened (10), Bright Bronze (11), Satin Bronze (12), Oil Rubbed Bronze (13), Bright Nickel (18), Satin Nickel (19), Antique Nickel (20), Black (22), Dark Bronze (24), Bright Chrome (25), and Satin Chrome (26).

Medeco 11TR624-19 – Frequently Asked Questions

1) Will the Medeco Maxum deadbolt fit a 2 inch thick door, and does it use the holes already in my door?
Doors from 1-3/8 to 2-1/2 inches thick are covered, so a 2 inch door is inside the range with nothing extra to order. The prep is standard ANSI A115.13: a 2-1/8 inch crossbore through the face and a 1 inch bore in the edge. If the deadbolt coming off the door was drilled to that prep, the Maxum goes back into the same holes with no new boring.
2) Do I order the Medeco Maxum deadbolt in a 2-3/8 or 2-3/4 inch backset?
Both backsets are offered, and the door decides it, not preference. Measure from the edge of the door to the center of the 2-1/8 inch crossbore. 2-3/8 inches is the usual residential setting; 2-3/4 inches turns up on heavier doors and most commercial preps. Order the wrong one and the bolt will not line up with the strike pocket in the jamb.
3) Should I use a double cylinder deadbolt like the Medeco 11TR62, or a single cylinder with a thumbturn?
The Maxum 11TR62 is the double cylinder version, keyed on both sides with no thumbturn. That is the right call when there is glass in or beside the door, because breaking the glass and reaching in gets an intruder nothing to turn. The trade off is real: anyone inside needs a key to get out, and many jurisdictions do not permit that on a required egress door. If the door has to open from the inside without a key, order a single cylinder Grade 1 instead, such as the Dexter DB1000 single cylinder or the Accentra D111.
4) Can somebody get a copy of a Medeco Maxum key cut at a hardware store?
No. Maxum keys carry angled cuts plus fore and aft pin positioning, which takes a special key cutting machine and Medeco specific blanks, so a hardware counter or a mall kiosk cannot produce one. The cylinder is solid brass with hardened steel inserts and rotating pins for pick and drill resistance to UL 437, and it holds ANSI/BHMA A156.30 certification for key control and duplication protection. For a landlord or a facility handing keys to tenants and contractors, that is the reason to buy this rather than a Grade 1 deadbolt on a stock keyway.
5) Will this deadbolt actually stop a kick in, and does a strike plate come with it?
A box design high security strike is included, and it is anchored with 2 inch screws that pass the jamb and bite into the framing behind it. That is the part that stops a kick, so make sure those screws land in the stud rather than just the jamb trim. The bolt itself is a solid 1 inch hardened steel bolt with its throwing mechanism inside a heavy gauge tubular steel housing, and a steel shroud covers the bolt against ice pick style attacks. Certified BHMA A156.5 Grade 1.
6) I have a 2-1/4 inch thick entry door. Which double cylinder deadbolt will fit it?
The Maxum is the one that reaches, covering 1-3/8 to 2-1/2 inch doors. Most double cylinder deadbolts stop short of that: the Dexter DB1000 double cylinder is listed to 1-7/8 inches, the Deltana 7312KA2 to 2 inches, the Hager 3214 to 1-3/4 inches, and the Design Hardware D1 to 1-3/4 inches. If you would rather have a commercial cylindrical deadlock than residential trim on that opening, the Corbin Russwin DL3011 is listed for 1-3/4 to 2-1/4 inch doors.
7) Can a Medeco Maxum deadbolt be added to an existing Medeco master key system?
Yes, into an M4 system. Maxum deadbolts master key with M4, M4 BiLevel and M4 CLIQ keys and cylinders, so mechanical and CLIQ electronic cylinders can run under one schedule, and the angled cut geometry supports very large systems. Cylinders come 5 or 6 pin and the keyway is set at the factory, so hand over the keying detail with the order rather than planning to pin them in the field.
8) What is the closest Grade 1 double cylinder deadbolt to the Medeco 11TR62 Maxum?
The Design Hardware D1 Series double cylinder deadbolt is Grade 1, rated extra heavy duty, and prepped for 1-3/4" doors. The Dexter DB1000-DCT is also a Grade 1 double cylinder and covers 1-3/8" to 1-7/8" doors. Both take a key on each face the way the 11TR62 Maxum does. The Maxum is certified to BHMA A156.5 Grade 1, is UL 437 listed against picking and drilling, and fits doors 1-3/8" to 2-1/2" thick on a 2-1/8" crossbore with a 1" edge bore.
9) Which double cylinder deadbolt fits a door thicker than 2 inches?
The Medeco 11TR62 Maxum is built for doors 1-3/8" to 2-1/2" thick on standard ANSI A115.13 prep. Among the other double cylinder deadbolts, the Deltana 7312KA2 is listed for 1-3/8" to 2" doors, the Dexter DB1000-DCT for 1-3/8" to 1-7/8", the Dexter DB2000-DCT for 1-3/8" to 1-3/4", and the Design Hardware D1 for 1-3/4". Measure the leaf at the bore before substituting, because a thick solid core or a clad exterior door will exceed several of these ranges.
10) What Grade 1 deadbolt gives a thumbturn on the inside instead of a second keyed cylinder like the Medeco 11TR62 Maxum?
The 11TR62 Maxum is double cylinder, keyed on both faces. Where egress code or a facility standard calls for a thumbturn inside, the Dexter DB1000-SCT is a Grade 1 cylinder x thumbturn deadbolt for 1-3/8" to 1-7/8" doors, the Accentra D111 is a Grade 1 cylinder x thumbturn on a 2-3/8" backset for 1-3/8" to 1-3/4" doors, and the Deltana CL200LM is a Grade 1 single cylinder deadbolt. All three keep the same Grade 1 certification level while releasing from inside without a key.
11) How does keying the Medeco 11TR62 Maxum compare with a deadbolt cut on a Schlage C keyway?
The 11TR62 Maxum runs Medeco cylinders on the DL keyway with M4 key control, UL 437 listed against picking and drilling and certified to ANSI/BHMA A156.30 for restricted duplication, and it master keys into systems built with M4, M4 BiLevel and M4 CLIQ cylinders. The Hager 3214 double cylinder deadbolt is Grade 2 on a Schlage C keyway, and the Hager 3118 Grade 1 classroom deadbolt uses the same Schlage C keyway with a 6-pin cylinder, so blanks for those cut on standard shop equipment.
12) What is the difference between the 1 inch faceplate latch and the drive-in latch on the Medeco Maxum deadbolt?
Two latch styles are sold. The faceplate version has a plate that seats in a shallow mortise on the door edge, which is what most existing wood entry doors are already cut for. The drive-in has no plate and presses straight into the 1 inch edge bore, so nothing has to be chiselled. Order the drive-in for a door that has never had a deadbolt, or where you do not want to cut a pocket in the edge. Both use the same 1 inch edge bore, so the boring does not change either way.
13) What other Grade 1 double cylinder deadbolts are worth looking at besides the Medeco Maxum?
Two sit in the same class. The Design Hardware D1 Series double cylinder is Grade 1, extra heavy duty, for 1-3/4 inch doors. The Dexter DB1000 double cylinder is Grade 1 for 1-3/8 to 1-7/8 inch doors. Both give you the bolt strength. What neither gives you is the key control: restricted Medeco blanks that a hardware store cannot cut, and UL 437 pick and drill resistance. If the worry is keys walking off a jobsite or out of a rental, that difference decides it. If the worry is only somebody prying the door, the other two do that job.
14) Is the Medeco Maxum right for apartment unit doors across a building I manage?
It suits that use, and multi-unit residential on a master key system is one of its listed applications. This is Medeco's residential Maxum line rather than a commercial cylindrical deadlock, but it is not a light duty part: BHMA A156.5 Grade 1 for the deadbolt and ANSI/BHMA A156.36 Grade 1 for the cylinders. Across a portfolio the payoff is one M4 system covering every unit, with keys tenants and contractors cannot copy. For hollow metal commercial openings in the same building, the Corbin Russwin DL3011 cylindrical deadlock is the more usual specification.
15) I do not need restricted keys. Is there a simpler double cylinder deadbolt?
Yes, in Grade 2. The Hager 3214 double cylinder runs the Schlage C keyway and fits 1-3/8 to 1-3/4 inch doors, and the Delaney LU Series double cylinder is Grade 2 in a stainless steel finish. The Schlage C keyway means any locksmith or hardware counter can cut a key on the spot, which is convenient and is precisely what the Medeco is built to prevent. Choose on which of those two you actually want on that door.
16) Which double cylinder deadbolts are certified Grade 2 or Grade 3 rather than Grade 1?
The Dexter DB2000-DCT is a Grade 2 double cylinder deadbolt for 1-3/8" to 1-3/4" doors, and the Delaney LU Series 320601 is a Grade 2 double cylinder in stainless steel US32D. At Grade 3, the Callan 210S is a double cylinder deadbolt and the Deltana 7312KA2 is a Grade 3 double cylinder for 1-3/8" to 2" doors. The Medeco 11TR62 Maxum sits at BHMA A156.5 Grade 1 with a 1" solid hardened steel bolt in a heavy gauge steel housing.
17) Is a cylinder by blank deadlock the same thing as a double cylinder deadbolt?
No. The Corbin Russwin DL3011 and DL3211 are Grade 1 cylindrical deadlocks keyed on one side with a blank plate on the other, and the DL2211 is the same cylinder x blank arrangement in classroom function. The Callan 205S is a one sided half-bore deadbolt, and the Arrow E60 is a Grade 2 non-keyed exit deadlock with a blank plate outside and a thumbturn inside. The Medeco 11TR62 Maxum is double cylinder, meaning a keyed cylinder on both faces of the door.
18) Can an Arrow 460, a Baldwin 8BR0618001, or a BEST 8T be ordered in place of a Medeco 11TR62 Maxum deadbolt?
None of the three is a complete lock. The Arrow 460 is a mortise lock strike for latchbolt and deadbolt functions with a straight lip, listed for 1-3/4" doors. The Baldwin 8BR0618001 is a deadbolt spacer for double cylinder Reserve trim. The BEST 8T is the tubular deadbolt tube component of the T Series. The Medeco 11TR62 Maxum ships as a complete bored deadbolt including its box design high-security strike plate with 2" screws that anchor into the framing.
19) What deadbolt suits a door already prepped for a mortise case instead of a 2-1/8 inch crossbore?
The Medeco 11TR62 Maxum is a bored deadbolt on ANSI A115.13 prep, a 2-1/8" crossbore with a 1" edge bore, so it will not drop into a mortise pocket. For a mortise prep, the Dormakaba D900 is a small case mortise deadbolt taking a D cylinder, supplied keyed different on SC keyways, cylinder x thumbturn. The Emtek 2050 and 2051 are European mortise deadbolts with an integrated roller latch, square and round trim respectively, also cylinder x thumbturn.
20) Which deadbolt takes a small format interchangeable core so it can be pinned into an existing facility keying system?
The Arrow E61 26D IC is a Grade 2 single cylinder deadlock supplied with SFIC prep less core for 1-3/8" to 1-3/4" doors, so the facility supplies its own cores. The Deltana CL200LAIC is a Grade 2 interchangeable core deadbolt, non cylinder, on a 2-3/4" backset, and the Delaney LM Series 301702 is a Grade 1 less core single cylinder deadbolt in dull chrome US26D. The Medeco 11TR62 Maxum instead arrives with Medeco cylinders on the DL keyway and master keys within M4 systems.
21) What backset options do the alternatives to the Medeco 11TR62 Maxum deadbolt use?
The 11TR62 Maxum is built in both 2-3/8" and 2-3/4" backsets, so it can be ordered to the bore already cut in the door. The Accentra D111 is a fixed 2-3/8" backset and the Deltana CL200LA a fixed 2-3/4" backset. When the backset on site is unconfirmed, the Cal-Royal ED500 is a Grade 3 deadbolt with an adjustable backset, the Falcon D111 is a Grade 1 heavy duty deadbolt with an adjustable backset, and the Brinks Raleigh E2401 uses a 4 way adjustable backset.
22) Which deadbolt should be specified for a fire rated opening?
The Hager 3214 double cylinder deadbolt carries a fire rating, is Grade 2 on a Schlage C keyway, and covers 1-3/8" to 1-3/4" doors. The Hager 3115 and the Hager 3215 are fire rated cylinder x thumbturn deadbolts over that same thickness range, and the Hager 3118 is a fire rated Grade 1 classroom deadbolt with a 6-pin Schlage C cylinder. The Cal-Royal CRB800 is a Grade 1 heavy duty single cylinder deadbolt with a UL 3 hour fire rated latch.
23) Do I order the Medeco deadbolt with 5 pin or 6 pin cylinders?
Both pinnings are available. Six pin gives more usable key changes, so specify it if the deadbolt is joining a master key system or one you expect to grow. Five pin is enough for a standalone door or a small keyed group. Keep every cylinder in one system on the same pinning, otherwise the master schedule gets awkward to expand later.
24) Can I get the Medeco Maxum deadbolt to match the satin chrome levers already on my doors?
Twelve finishes are sold: 605 bright brass, 606 satin brass, 609 antique brass, 610 satin brass blackened, 612 satin bronze, 613 dark bronze oil-rubbed, 619 satin nickel, 622 flat black, 624 dark bronze, 625 bright chrome, 626 satin chrome, and 20 antique nickel. Those are BHMA finish numbers, so match by number rather than by the name on the carton. Levers stamped 626 or US26D take the 626 Maxum.
25) What is the classroom function deadbolt option when only the outside face should be keyed?
The Falcon D111 is a Grade 1 heavy duty classroom deadbolt in the D100 Series with an adjustable backset, and the Hager 3118 is a Grade 1 classroom deadbolt with a Schlage C keyway, a 6-pin cylinder, and a fire rating for 1-3/8" to 1-3/4" doors. The Corbin Russwin DL2211 is a Grade 1 cylindrical deadlock in classroom function for 1-3/4" doors. The Falcon D211 covers classroom function at Grade 2, medium duty, in the D200 Series.
26) What replaces mechanical key control with electronic credentials on a multi-unit residential entry door?
The Dormakaba Nova-D is an RFID multihousing smart electronic deadbolt, and the Dormakaba Saffire LX-D is an RFID electronic deadbolt with BLE and electronic lock override. The Delaney KP400 is a Grade 2 electronic deadbolt with a programmable remote, and the Codelocks CL2200 is a medium duty electronic surface deadbolt in brushed steel. The Medeco 11TR62 Maxum handles the same control mechanically, through M4 key control against unauthorized duplication and master keying across M4, M4 BiLevel and M4 CLIQ systems.
27) Which double cylinder deadbolts come in decorative residential trim?
The Emtek 8323 Modern Disc is a double cylinder deadbolt in brass, the Baldwin Reserve DC.CRD and DC.CSD are double cylinder deadbolts in contemporary round and contemporary square trim, and the Baldwin Estates 8011 is a contemporary 1-5/8" double cylinder deadbolt in entrance function. The Medeco 11TR62 Maxum is a residential deadbolt with a plain cylindrical rose, offered in finishes including 605 bright brass, 613 dark bronze oil-rubbed, 619 satin nickel, 622 flat black and 626 satin chrome.
