N Series Pin Tumbler Deadbolt For Door Security

A solid brass, pin tumbler cylinder is used in this lock, giving the core precise pin control that supports consistent key function over repeated use. The body is built from zinc die cast, creating a rigid housing around the cylinder that supports the bolt mechanism during locking and unlocking.

The lock is keyed to KA101, aligning it with N Series KA101 key systems in the same installation.

Deadbolt Details That Support Daily Use

• The zinc die cast body forms a stable structure around the cylinder, which supports the internal bolt components and helps the lock stay seated in the door prep during service.
• The N Series keyway, equivalent to National D4291 4-pin or D4292 5-pin systems, matches existing N Series key systems so the same key family can operate this deadbolt and other N Series locks.
• Stock keying listed as KD/KA with a 4 pin standard setup allows this deadbolt to participate in keyed different or keyed alike systems, supporting straightforward key control planning on a project.
• Stock KA numbers 101, 103, 107, and 915 provide defined keyed alike groups, which helps installers coordinate doors that need shared access under specific KA numbers.

Door Lock Installation And Cylinder Handling

The cylinder in this deadbolt is rekeyable via a set screw cylinder release mechanism, which allows the core to be removed and rekeyed without discarding the entire lock body. This mechanism gives locksmiths and installers a defined method to change keying while retaining the existing hardware in the door. Cylinder lengths of 15/16 inch, 1-3/8 inch, or 1-5/8 inch are specified, providing size options to match different door thicknesses or hardware stackups that accept these cylinder dimensions. A barrel diameter of 7/8 inch is used, which aligns with preps designed for this cylinder size so the lock can seat properly in the hole. The standard function allows the key to be removable in either the locked or unlocked position, giving users flexibility in how the key is managed during operation.

Using This Olympus N Series Deadbolt In The Field

Where This KA101 Keyed Deadbolt Is Applied

This deadbolt is part of the Olympus N Series, so it is suited to doors that are already specified for N Series keying or that are being set up on an N Series system. Because the lock can be keyed together with other N Series locks, it supports installations where one key family is used across multiple openings, such as mixed hardware doors that share a common keyway. The KA101 stock keying on this model ties directly into KA101 key groups, which is useful when a site uses KA101 as a standard and needs additional doors locked to that same key number. When N Series keyway equivalence to National D4291 4-pin or D4292 5-pin systems is required, this deadbolt aligns with those patterns so the key system can stay consistent across new and existing hardware. The satin chrome finish helps it match other satin chrome door components in a run of openings that follow a coordinated finish schedule.

Details That Support Reliable Locking Performance

The deadbolt has passed ANSI/BHMA A156.11 Grade 1 performance requirements, equivalent to E07121(100DR), which indicates that the lock has been tested to a performance level suitable for applications that call for Grade 1 deadbolt hardware. This performance level helps installers select it for doors where a higher duty rating is specified by standard. The standard function design, with the key removable in both locked and unlocked positions, allows users to operate the lock and then remove the key in whichever state is required by their routine. For projects that call for a different function where the key is removable in the locked position only, that variation is noted as available via direct ship, which supports specifications that need that operating mode. Masterkeyed operation is available as a 5 pin standard, with grand masterkeyed capability available, tying this lock into larger key hierarchies where multiple levels of key access are planned across a facility.
