Types of Garage Door Locks

Choosing the right lock depends on your garage setup, security needs, and budget. Here are the most common types:

Keyed locks require a physical key to operate and provide an extra layer of security. They are often used on swing-out or sectional doors.

Modern smart locks offer remote access via apps or keypads. Some can even integrate with home automation systems for enhanced security.

These locks physically block the door’s movement, making them extremely secure. They are often paired with other types for maximum protection.
