A medicine cabinet lock can prevent young children from accessing harmful substances that you keep in the cabinet. Follow these steps to to fit a lock safely and securely.

Step 1 - Assess the Cabinet

Fitting a lock largely depends on the shape, size, and material of your medicine cabinet. If it is plastic, you may have trouble getting a lock to stay put. Plastic can crack and fracture, so you might need to replace the cabinet with a more solid unit. If your existing cabinet is made of wood or another material, you can proceed with the project.

Step 2 - Choose the Lock

Choose a medicine cabinet lock that you know will be secure, such as a padlock, combination lock, or keyless lock. If you buy a hasp and staple separately from the medicine cabinet lock, you must ensure that the lock will fit through the ring of the hasp.

Step 3 - Mark the Screw Holes

There are 2 ways to fit the hasp. You can situate it on a corner or on a straight side of the cabinet. Mark the place where the screws will go to hold the hasp. Drill pilot holes in the cabinet, but try not to drill all the way into it. The thickness of your cabinet material will determine how far to drill.

Step 4 - Fit the Hasp and Staple

Set the hasp where you marked the holes and apply the screws to fix it in place. Tighten the screws, then test the match between the hasp and staple to ensure they are in perfect unison. Once you are happy with the positioning, you can test the lock.

Step 5 - Attach the Medicine Cabinet Lock

Open the padlock or combination lock and hook it into the ring of the hasp. Set the combination lock to a number you will remember. Close it and make sure it fits easily. If the padlock requires a key, test it before you place it in the ring and close it. If you are happy with the fitting, you are set to go.
