The Five Typical Lockset Functions

Lever Lockset Function

How can you determine the right lockset type for your needs? This is a question that often doesn't cross most people's minds until they find themselves wandering the aisles of a hardware store or standing in front of a locksmith's shop. Frequently, individuals resort to vague terms like "regular" or "standard" when describing the lockset they intend to buy. Regrettably, manufacturers don't label their locks with such terms, leaving consumers in a guessing game. But let's eliminate the guesswork! Here's some industry wisdom and terminology to empower you as a more knowledgeable shopper:

(Although there are additional lockset functions beyond these five, they are quite rare and only necessary for specific situations.)

  1. Entry Lockset Function: This is the most prevalent type of lock, and chances are you already have one on your home or office door. An entry function lockset typically includes a small button on the interior knob or lever, allowing you to manually lock the door when desired. Most types permit you to either push the button in or push and turn it, keeping the door locked even after a key is used. These are commonly found on residential front and back doors.

  2. Storeroom Lockset Function: This lock is perpetually locked and necessitates a key for every entry. There's no interior button, nor an option to leave the door ajar. It's ideal for commercial purposes, securing supply closets to ensure the door stays locked as long as it's closed. After all, no one wants their office supplies to mysteriously disappear!

  3. Classroom Lockset Function: As the name suggests, this lock is designed for classrooms. Much like the storeroom function, it lacks an interior button. However, it offers the option to leave the door unlocked but only with the correct key. A full turn of the knob or lever either locks or unlocks it, granting control over door access to authorized individuals. This is an excellent choice for those who wish to restrict door access to authorized personnel.

  4. Privacy Lockset Function: Primarily used in bathrooms and bedrooms, this lockset is intended for privacy. It typically features a small hole on the exterior and a push button on the interior. The small hole on the exterior can be opened with a pin or paperclip, providing a simple way to unlock the door from outside. These locks aren't intended for high security but rather to prevent unexpected intrusions when using the bathroom or changing in a bedroom.

  5. Passage Lockset Function: This is more of a door latch than a "real" lock. It doesn't actually lock; it merely keeps the door latched to the frame to prevent it from swinging freely. You'll often find these on closets at home or on doors that don't require locking. Some people also use them on bedrooms to allow door closure without locking.

And there you have it! So, the next time you're shopping for locks, you can use this knowledge to determine which lockset functions are appropriate for each door. This way, you can customize your home or business to your liking, saving time, money, and frustration in the process.
