Customer Questions & Answers

  1. Answered by the admin

    This model is fully mechanical and does not use batteries for power. The lock does feature a passage mode that will keep the door unlocked if the R button is pressed with your combination. To disable the passage model, press the R button followed by the C button. Lock will remain locked and relock after each opening until a code + R is entered again.

  2. Answered by the admin

    The Lockey 3835 is a single sided lock, where its normal use is to have the keypad side require a code to get in and being able to exit freely without entering any codes.

  3. A

    This lock is fully mechanical so it should not cease function in extreme temperature environments.

  4. Answered by the admin

    Lockey gate locks can be installed on vinyl, wood or metal. You do not need a gate box for wooden gates.

  7. Q Does marine grade mean in a salt-air environment? answer now
    Asked by Jon Rickard on January 27, 2022 7:26 AM
    Answered by the admin

    The Lockey marine grade models were designed for salt-air ocean environments. The internal parts are teflon coated and offer a marine-grade finish on the exterior for enhanced corrosion resistance. 

  8. Q Can these be installed on a 1-3/4" thick aluminum commercial door? answer now
    Asked by Marge Pokrzywinski on January 26, 2022 2:20 PM
    Answered by the admin

    This model can certainly be used on an aluminum door that is 1 3/4" thick as long as the door allows for a backset of at least 2 3/8".

  9. Answered by the admin

    These two models function exactly the same. The 2835 model is rated for light/medium usage and the 3835 model is rated for medium/heavy use applications. 

  10. Answered by the admin

    The inside unit is always able to retract the latch. If you need both sides to be locked, we would recommend the Lockey 3835DC.
