  3. Great Locks: Easy to Install, Works Well, and Looks Great


    We didn’t want to carry any more keys then we already had, but wanted secure locks for both of our gates and our work studio in the back. We also wanted the security of a mechanical lock to avoid some of the mishaps our friends are having with their digital locks. We did our homework and found very few that were good quality, we a relatively small size (didn’t overwhelm the doors), and stand up to the elements as an external lock. Then we found the Lockey C-120. It was easy to install, it works smoothly, we got to choose our lock code, and can change the code whenever we want. Sturdy, attractive, and functional.

    Worked great for an awkward gate where most other locking mechanisms wouldn’t work. The code can’t be set to creat a specific sequence of numbers, like 1357, but instead works if those four numbers are entered in any sequence, like 7531 or 5731. If you are concerned about that, you can increase the amount of numbers in the code, making it more difficult for the code to be randomly guessed.

  5. LOCKEY C-120

    Just installed it. I like its compact size and sleek look.
    One thing I would suggest, the info re the coding in the manual should be more clear.

Customer Questions & Answers

  1. Q Can I retrofit this onto a metal cabinet door? answer now
    Asked by B on November 28, 2020 8:52 PM
    Answered by the admin

    This lock can be used for metal cabinet doors but may require a Thin-Door kit to mount properly. The Thin-Door kit for this model can be found here: https://www.gokeyless.com/product/lockey-thin-door-kit/

  2. Answered by the admin

    Since this is a mechanical deadbolt, the lock is not able to lock automatically on its own. For models that do have this feature, please contact our sales team at 937-247-9327, option 1!

  3. Answered by the admin

    Thick door kits are available for doors up to 5" thick! The extension kit needed can be found here: https://www.gokeyless.com/product/lockey-extension-kit/

    You will need to remove the lock from the cabinet and swap the tumblers in the back of the lock to the new code.
