Your garage door is more than just a convenient entry point—it’s a crucial part of your home’s security system. Whether you park your car inside or use the garage for storage, keeping it secure protects your belongings and your peace of mind.
Understanding Garage Door Locks
Before beginning the replacement process, it’s helpful to understand the types of locks you may encounter and how they operate.
Types of Garage Door Locks
Garage door locks come in various forms, each suited to different needs and door types:
- Manual locks: These are traditional locks operated with a key or thumb turn, often installed on the inside of the garage door.
- Electronic keypad locks: Allow keyless entry by entering a code. Great for convenience and shared access.
- Smart locks: Connected to your smartphone or house design automation system, offering remote control and monitoring.
- Deadbolts for garage entry doors: If your garage has a separate door from the house, a deadbolt adds an extra layer of security.
Components of a Typical Garage Door Lock
Most garage door locks share standard parts:
- Lock cylinder: The part where you insert the key.
- Latch or bolt: Moves in and out to lock/unlock the door.
- Handle or thumb turn: Used to operate the lock from inside.
- Strike plate: Mounted on the door frame to receive the bolt.
Understanding these parts helps when inspecting or replacing your lock.
