Lockey 2500KO Surface-Mount Hookbolt Keypad Lock with Built-in Key Override

The Lockey 2500KO Hookbolt Keypad Lock is the same as the Lockey 2500 except that it has a key override built into the knob handle which is slightly larger than the knob of the 2210. This is a keypad lock for a sliding door, a pocket door, a sliding gate, a wall door, or any sliding panel that needs a hook-type mechanism to secure and lock it.
  • The hook mechanism of this combination lock rotates and catches on the strike plate/catch when the knob is turned to the locked position.
  • This versatile keypad door lock works on doors that slide open in either direction and on pocket doors, too.
  • It can be installed on a thick door or gate up to 3" thick with the optional Lockey Thick Door Kit.
  • For a model without a built-in key override, see Lockey 2500 Sliding Door Keypad Lock.
  • This keypad lock is not available with a double-sided keypad. For a double-sided lock, try one of our other hook door locks.
  • We also carry replacement lock bodies for the inside and outside of this surface-mount lock. For replacements, view our Lockey Replacement Lock Bodies - 2500.

  • USE WITH THE MANUFACTURER'S BUILT-IN SLIDING DOOR LOCK: The most common configuration is to leave your existing lock in place and install this sliding door keypad lock either above or below it. That ensures you will have a large, strong handle to pull your door open/closed and it also gives you added security. Also, sliding glass door locks come in many sizes and shapes--it can be difficult to find a keyless lock that will fit in the existing holes in your door.
  • TWO WAYS TO INSTALL: The catch for this lock can be used two ways:
    1. It can be mounted flat on the frame (i.e., in the same plane as the door), as shown in the diagram below. In this case, the lock's hook will go into the opening on the side of the catch.
    2. Or, it can be mortised into the wall (i.e., perpendicular to the plane of the door). In this case, the lock's hook will go into the opening on the front of the catch.
  • A SIMPLE CONFIGURATION: Here is a diagram of the simplest type of installation (descirbed in #1 above).

Locking and Unlocking

UNLOCKING a keypad combination lock is quick and easy:

  • On the inside, you don't need the combination to lock this sliding door keypad lock—just turn the turn knob or thumb turn to retract the deadbolt.
  • On the outside, first press the "C" button or turn the thumb turn as far as it will go. This will clear out any previous keypad entries.
  • Next, enter in the secret code.
  • Finally, turn the knob, lever handle, or thumb turn to retract the deadbolt.

LOCKING is even easier:

  • Just turn the knob, lever handle, or thumbturn to extend the deadbolt of this surface-mount lock into the locked position. You don't even need to enter the code.

It is so easy, once you've tried it, you'll wonder how you lived without it!
