How to install a lock on a refrigerator or freezer

Updated February 21, 2017

There are many reasons to add a lock to a refrigerator or freezer. Many chest freezer models come equipped with a lock, but many upright freezers and almost all refrigerators do not have a lock option available. If purchasing a refrigerator with a lock is possible, go for it. But if it is not, there is hope. Locks are available that will secure the contents of your refrigerator or freezer. Drilling holes into the door and the body of the unit is generally not a good idea, whereas self-stick locks are effective and install easily.

Choose the location of the refrigerator or freezer door lock, and clean the site with rubbing alcohol and a cotton ball. The rubbing alcohol will strip contaminants off the surface of the door and allow the door lock to stick better.

Peel the backing off one of the self-stick pads of the door lock. Stick one side to the door at a time.

Peel the backing off the other self-stick pad with the padlock in place between the two pieces of the refrigerator or freezer lock. Attach the self-stick pad to the body of the refrigerator or freezer.

Tug on both self-stick pads to be sure they are securely in place.


Do not drill through the shell of the refrigerator or freezer unless you are familiar with what is underneath the surface of the area where the screws will enter the shell. The screws may enter critical cooling or electrical components of the refrigerator or freezer with expensive repair consequences.
