Take down weak security at your gates with Sumo! You can depend on the SUMO GL2 Surface Mount Gate Lock to protect your pool, dock or beach access after hours. Using the keyed cylinder lockout function, staff can lock the gate with the key and render the keypad inoperable. Everything will be locked down for the night so even users with the code cannot enter. The deadlocking spring latch prevents tampering, meaning no one will be able to jimmy the lock open. Passage mode is for times such as swimming or boating competitions, community pool or dock parties, or simply operating hours, where you have a lot of people coming and going through the gate. You don’t have time to be waiting for people to enter a code for each access. This lock is excellent for gates that surround your indoor and outdoor pools, private beaches, or other liability areas to keep children from harm when you aren’t around to supervise them. No welding needed as the lock housing secures to your existing gate with the included mounting kit. Weather resistant and built from zinc plated steel, it will function in any situation. The SUMO GL2 is ideal for ornamental, aluminum, vinyl, and wood gates.

What others are saying

  1. Great lock but not solidly built

    Noel Raphael (verified owner)

    The lock design is great and works well for a low traffic area. We used ours outside on our entrance to our rubbish area for our condo association. If the door closes too fast, the bottom bolt will snap off. Also, with many people turning the lever handle, the set screw that holds it in place gets worn quickly and then the handle is useless.
    I would have designed the handle with a stronger screw that goes into the inside cylinder rather than try to grip it through pressure. We can’t use this lock so we are looking for other options that will better suit our needs.

  2. Non disclosure of requirements to maintain warranty

    Jerry (verified owner)

    In order to maintain lifetime guarantee it is required for the lock to have a hydraulic closing assist. This was not disclosed anywhere in the description. It is a 1 sentence passing comment in the installation instructions.

  3. Home gate security


    Ordered this latch without really knowing if it was right for the job. Turns out that it was really sturdy and exactly what we needed for additional security on a busy street. The lock/latch system is so adjustable that it would fit just about any gate.

  4. As advertised

    Robert Austin (verified owner)

    The directions were easy to follow. Took some effort, but is well worth it.
    One problem, one call to technical support, and problem resolved.
    I will buy more of these locks for our other pool gates.

Customer Questions & Answers

  1. Q Can the code be changed or is there just one code the whole time? answer now
    Asked by Shernetter on May 21, 2022 10:24 PM

    You can change the access code whenever you desire. Please keep in mind that the lock will need to be uninstalled to change the access code to a new combination. 

  2. A

    To put the lock-in and out of passage mode, you will want to press the Y button after entering your access code before pulling on the lever. When the Y button is depressed with your combination, this will toggle the unit to stay unlocked or lock down when the handle is rotated. 

  3. Q Can you get a replacement handle? answer now
    Asked by Arunas Stungurys on January 15, 2022 10:36 PM

    Lockey handles warranty replacement parts. You can contact them directly here: Lockey Support

  4. A

    The interior handle is always set to passage mode. The exterior side can be set to passage and deactivated as desired. 

  5. A

    The handles can be reversed to operate in either direction. However, the keypad side will need to be installed on the same side as the bolt. A double combination model is available if required. 

    Lockey SUMO GL2DC Double Sided

  6. A

    The latch bolt has a security screw that must be set while installing the lock onto the gate. This security screw ensures that the bolt cannot be unscrewed while the lock is installed.

  7. A

    You would be correct! Each button is pushed independently until the full code is complete. Once the valid code has been entered, pulling down on the handle will retract the latch.

  8. A

    The maximum thickness that this lock will support is 3 1/2 in.

  9. A

    You would have the ability to install the lock in this manner. However, the noncoded side acts as a passage handle and will unlock the latch when turned.

  10. A

    A closing bar is also known as a gate closer. This is a device that prevents your gate from slamming shut after entry. You may use any gate closer you wish for your application.
