The Lockey 3835 Double Combination Passage lever lock is perfect for securing a door, gate, or facility and keeping your property protected. All it takes is your unique code and a push of the lever 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 1150DC.

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 2835DC.

    Excellent for Special Needs

    Krissy Banzet (verified owner)

    I have an Autistic 7 year old son, who is an escape artist. These locks have been such a stress relief for me.
    Being a single parent it’s hard to keep track of him at all times. (Morning, noon and night) Now I can actually sleep at night because I don’t have to worry about him getting out of the house.

    Not impressed with the construction of this lock. The handle fits loosely even with the set screw tightened, feels cheap. You have to remove the lock completely to change the code, not user friendly.

Customer Questions & Answers

  1. Answered by the admin

    This lock does have a passage mode function so that the lock remains unlocked after a code is entered when desired. 

  2. Answered by the admin

    Yes, the lock will need to be removed from the door in order to change the combination. 

  3. Answered by the admin

    This model is a double-sided version that would require a code to both enter and exit through the door. 

  4. Q Does the lock require batteries? answer now

    Answered by the admin

    The Lockey 3835DC is fully mechanical and does not require any batteries to operate!

  5. Q What type of housing do we need to purchase with this lock? answer now
    Asked by Jessica Richardson on July 22, 2019 3:54 PM
    Answered by the admin

    No additional housing is needed to mount this lock unless you are attempting to mount this on a gate with no space available to mount the lock. In this case, you would need to purchase a weldable gate box to mount the unit. 

  6. Answered by the admin

    The Marine Grade finish is the same cost as the other finishes so there is no difference in pricing.
