N Series Pin Tumbler Deadbolt Door Lock, Satin Chrome, Keyed Different, 15/16" Cylinder Length
Description
N Series Deadbolt Lock For Secure Door Control
N Series pin tumbler deadbolt door lock defines this Olympus Lock, Inc. unit as part of a keyed system that can be keyed together with other N Series locks, which supports planned key control across multiple openings. The satin chrome finish described in the name provides a clean, neutral appearance that works well in many commercial or shop environments where hardware needs to look consistent. The product is identified as keyed different in the name, which means each lock is supplied on its own key change in stock keying and that helps keep separate doors on separate keys when a project calls for individual access. The product sits in the deadbolt locks product class, so it provides a positive bolt action rather than a spring latch, which matters when a job requires a true deadbolt function on a door. The manufacturer part number 100-26D78-KD ties this specific configuration to ordering and replacement tasks in the field.
Deadbolt Details That Support Real-World Jobs
- The body is zinc die cast, which creates a rigid housing that supports the cylinder and bolt mechanics so the lock can perform consistently when installed in a door prep.
- The cylinder is solid brass with a pin tumbler design, which provides a well-established locking mechanism that works smoothly with the N Series keyway specified for this product.
- The cylinder length is listed as 15/16 inch, 1-3/8 inch or 1-5/8 inch, so the series offers different depths that allow selection to match door thickness or hardware cutout requirements.
- The barrel diameter is 7/8 inch, which defines the hole size needed in the door or hardware, helping installers align boring operations and retrofits to this dimension.
- The lock passed ANSI/BHMA A156.11 Grade 1 performance requirements, equivalent to E07121(100DR), so it meets a recognized standard that supports use in demanding commercial or institutional applications.
- The standard function allows the key to be removable in the locked or unlocked position, which lets users remove the key after locking or operating the bolt without being constrained to one position.
Installation And Rekeying Function For This Deadbolt
The product description notes that the lock is easily rekeyable via a set screw cylinder release mechanism, which means the cylinder can be removed without destroying components and that simplifies key system changes during maintenance or tenant turnover. The standard function locks are described as non-handed, so the same lock body works on either hand of door, which reduces part variation when stocking for multiple openings. The key removable in locked or unlocked position function allows the cylinder to be rotated to either position and the key withdrawn, which supports user habits in both secure and day-to-day operating modes. The equivalent E07121(100DR) reference in the ANSI/BHMA statement ties this deadbolt to a known function category, which helps match it to project specifications that call out that equivalent code.
Deadbolt Use, Keying System, And Project Fit
Where This N Series Deadbolt Lock Is Applied
The product is categorized under deadbolt locks and specifically described as a deadbolt door lock, so it is intended for door applications where a bolt is projected for security rather than relying on a spring latch. The ability to be keyed together with other N Series locks means this deadbolt fits into a broader N Series key system, allowing doors, drawers, or other N Series-equipped hardware to operate on common keys when planned that way. The keyway is defined as N Series, equivalent to National D4291 4-pin or D4292 5-pin system, which ties the lock to a familiar key profile for locksmiths and shop personnel who already work with that standard. Stock keying is listed as KD/KA - 4 pin standard, which indicates that in stock conditions locks may be keyed different or keyed alike within the 4-pin configuration, giving options for individual or shared access on a project. Stock KA numbers 101, 103, 107, and 915 are specified, which creates clear reference points when matching or extending keyed-alike groups in an installation. The product is also masterkeyed as 5 pin standard with grand masterkeyed available, so it supports tiered key control layouts where individual doors have their own change keys under a master.
Why N Series Cylinder And Grade Rating Matter
The solid brass pin tumbler cylinder paired with the N Series keyway establishes a serviceable core that locksmiths can pin to the N Series 4-pin or 5-pin systems mentioned, which supports both simple keyed-alike sets and more complex master keying. The easy rekeying via set screw cylinder release mechanism allows the cylinder to be taken out for re-pinning or replacement, which saves time during rekey projects because the lock case can remain in the door prep. The ANSI/BHMA A156.11 Grade 1 performance requirement statement signals that this deadbolt lock meets a high test level for this category, which matters when selecting hardware for doors that experience heavy operation or where project documents reference that standard. The identification as non-handed means the same lock can be oriented for either door swing without different part numbers, which simplifies both ordering and on-site layout when door handing changes. The option for key removable in locked position only is also noted as available via direct ship, which allows projects that require keys trapped in the unlocked position to specify that special function for controlled environments. The ability to be keyed together with other N Series locks and tied into masterkeyed or grand masterkeyed systems offers a structured key hierarchy for facilities that need layered access control across multiple openings and hardware types.
