Lock Cylinders

The lock cylinder, also known as the door barrel, is the crucial component that allows you to lock and unlock your doors. When you insert your key into the cylinder, its rotation activates the lock mechanism, securing your home. Ensuring you have a high-quality lock cylinder is essential for maintaining the safety and security of your property.

A malfunctioning door lock cylinder doesn’t mean you need to replace the entire door. You can easily and quickly find the right lock cylinder from the wide selection available at Thirard.
