Features

• Handles 300 Users: The iButton Eternity E4 Keypad/Combination Entry Door Lock can be programmed to control up to 300 iButton or key pad users, making it an ideal programmable combination lock for doors in corporate buildings.
• Deletes/Deactivates Individual Users: The iButton Eternity E4 Keypad/Combination Entry Door Lock lets you delete, deactivate, and in-activate users quickly and easily without knowing their unique index code. This useful upgrade means one less thing you need to keep track of.
• Able to Grant Access for Certain Hours: This lock can be programmed to grant access only during certain hours based on the day of the week. This is true 7-days a week, 24-hours a day. This is great for employees who need to be in the office only during standard business hours or shift employees who should only have access during their own shift.
• Has Auto-Lock & Auto-Unlock Feature: The iButton Eternity E4 lock has features that can be programmed to automatically lock or unlock everyday at a specific time. No need to set this up manually at the lock each time. This is a great feature for retail stores or businesses that open and close each day at the same time.
• Adjustable Lever Handle:The lever handles on the iButton Eternity E4 Keypad/Combination Entry Door Lock are field-adjustable, so you can use it as either a left handed or a right handed lever. This is great if you might move your lock to a new door with hinges on the opposite side.
• Can be Used Inside or Outside: This lock is durable enough to be used either on an external or internal door. If it is going to be used outside, we do suggest you buy an iButton Protective Lock Cover. This shields the inside and/or outside lock body from strong weather.
• Has a Passage Mode: This lock can be set to a passage mode where no code is needed to open the door, then easily be locked again, with the touch of just one button.
  
• Has a One-Touch Quick Lock Button: which does the following:
  
  • locks an Eternity E4 lock from the inside (multiple button presses have no effect since this button cannot unlock an lock)
  • doesn't change the E4's mode (passage or storehouse)
  • once pressed, users can still authenticate in from the outside (via a valid code, iButton, or a key)
  • is useful only if the E4 is in passage mode when it could be in either a locked or unlocked state
  • is irrelevant if the E4 is in storehouse mode when it will always relock after each use and users will always need to a valid code, iButton, or a key to get in
  • can be disabled, if needed (click here for instructions)
• Batteries Last an Extra Long Time: Because the keypad is not lighted, batteries last a lot longer than comparable locks.
• Stands up to Rigorous Use: The extra heavy weight lock body and handle of this specific lock are designed to stand up to rigorous use.
• Can be Programmed on the Lock or on a PC: The iButton Eternity E4 can be programmed on the lock or on a PC, using the optional PC Audit Trail Kit. This makes programming much easier and quicker if you have many users or locks and provides a backup and disaster recovery, if needed.
• Retrofits on Standard Doors: Like all iButton locks we carry, the iButton Eternity E4 Lock is designed for easy Do-It-Yourself installation on standard residential and commercial hinged doors. Just remove the existing door handle or deadbolt and insert this one in its place. The batteries are in the inside lock body, so there is no external wiring to be done.

Latchbolt Types & Handedness

With this lock, you have the option to choose a Mortised Latchbolt/Deadbolt Combo for the Latch Bolt Type below. This is the perfect option if you would like the added safety and convenience of a dead bolt combined with the security of the latch bolt.

How the Mortised Latchbolt/Deadbolt works: While unlocked, simply turn the handle up to enable (lock) the deadbolt and down to disable (unlock) the deadbolt. The latchbolt parts works just like a regular latchbolt meaning it locks automatically when the door is closed.

We do not recommend using on a narrow stile storefront door because the holes needed for this lock can compromise the strength of the door.
