A patio door is a popular feature in today's homes because it provides light, air and easy access to outdoor living space. Unfortunately, it also provides an accessible entry for burglars because the built-in lock can be disabled and because the door is typically in the back or on the side of the house, where it's concealed from view. Many see a patio door makes a home vulnerable so a lock is a popular addition. You can feel more protected from home intrusion by installing a lock designed specifically for a patio door.

There are several different models of locks for patio doors. One is designed to lock in several positions, allowing a 3-inch ventilation opening without minimizing security. This kind of lock is also an effective way to childproof a house and keep little ones from getting out while still allowing the breeze to enter.
