Frequently Asked Questions (FAQs)

1. Can you deadbolt a sliding door?

Sliding doors come equipped with small latches that hook onto a piece of metal in the door's frame. These latches are generally operated by moving a small lever and are extremely easy to open. Therefore, the locks on sliding glass doors simply cannot offer the high level of security that a good deadbolt lock does.

2. What kind of lock is best for a sliding door?

One simple type designed to secure sliding doors is called a two-bolt locking system. You can find these locks online or in a reputable hardware store. They are simple to install and can be installed at any height on the door.

3. Can you put a lock on sliding door?

The strongest way to secure your sliding door is with a sliding door lock. These locks are installed at the top of your door where the stationary glass and the sliding glass door meet. These locks work in addition to the door locks and can only be opened by an adult or tall child.
