Quick Answer

Flex locks are adhesive-mounted cabinet locks that secure cupboards from the outside. They are easy for adults to open but difficult for toddlers, making them a practical choice for kitchens, bathrooms, and offices. Installation takes about 10 minutes per lock with no tools required.

What You Need Before You Start

Before installing flex locks, gather the flex lock kit (typically includes two locks and adhesive strips), a clean cloth, and rubbing alcohol for surface prep. Make sure the cabinet surface is smooth, dry, and free of grease or dust—kitchen cabinets near the stove or sink often have residue that can weaken adhesion. Flex locks work best on flat, non-textured surfaces like painted wood, laminate, or metal. If your cabinets have deep grooves or a rough finish, consider a different lock style or use the included screw-mount option if available.

Choosing Between Flex Locks and Other Cabinet Locks

Flex locks are a surface-mount option that attaches to the outside of cabinet doors. They differ from magnetic locks, which are installed inside the cabinet and require a key to open. Flex locks are visible but easier to install and adjust, while magnetic locks offer a cleaner look but require drilling and alignment. For renters or quick setups, flex locks are the simpler choice. For a more discreet solution, magnetic locks may be worth the extra effort.

Step-by-Step Flex Lock Installation

  1. Clean the cabinet surface: Use a cloth with rubbing alcohol to wipe the area where the lock will attach. Make sure it is completely dry before proceeding. Common mistake: skipping this step can cause the adhesive to fail within days, especially in humid kitchens.
  2. Peel and position the adhesive strip: Peel the backing from the adhesive strip on the lock body. Press the lock firmly onto the cabinet door near the handle, ensuring the strap aligns with the catch on the cabinet frame. Check alignment before pressing firmly—once the adhesive bonds, repositioning is difficult without damaging the strip.
  3. Attach the catch piece: Peel the backing from the catch piece and press it onto the cabinet frame so the flex strap hooks into it when the door is closed. The catch should sit directly opposite the lock body. If the catch is too high or low, the strap won't engage properly. Test by closing the door and pulling gently.
  4. Test the lock mechanism: Close the cabinet door and slide the flex strap into the catch. Try to open the door with a toddler's pull to confirm it holds. Then practice opening it yourself using the release tab. If the door opens too easily, the adhesive may need more time to cure (24 hours for full strength). Avoid heavy use immediately after installation.
