The Lockey 3830 Double Combination Passage Knob Lock is perfect for securing a door, gate, or facility and keeping your property protected. All it takes is your unique code and a twist of the knob to open. Double combination means you have to enter the access code for each side of your door. Great for beach access and pool gates where you want to control who is coming in and out of the property. The lock is keyless and mechanical so you don’t have to worry about keys getting stolen, duplicated or lost! Customize lock access with convenient auto-locking and passage mode features. Auto-locking ensures your door or gate is securely locked every time you close it. Passage mode allows users to come and go as they please without needing to use the entry code. Ideal for backyard family gatherings. Weather resistant and built from zinc plated steel, the lock holds up equally well in both interior and exterior environments. Available in Marine Grade finishes to protect the lock when installed in a salt-air location.
If you have a heavier door or want more heavy duty industrial strength that stands up to a corporate office environment with people constantly using the lock, check out the Lockey 1600DC.
If you want a medium duty option like for a backyard pool gate, where there isn’t much foot traffic, take a look at our Lockey 2830DC.
