Secure and Upgrade Your Sliding Doors

Sliding door lock cylinders and sliding locks are essential components designed to keep patio, balcony, and backyard doors protected from forced entry while ensuring smooth operation. Whether securing residential spaces or commercial properties, these cylinder locks provide high-security solutions tailored to modern sliding glass and metal doors. Our selection includes replacement door lock cylinders, sliding lock with key options, and barrel cylinder lock sets for a variety of applications and brands.

Types of Sliding Door Cylinder Locks

Our inventory features several types of sliding door and patio door lock cylinders, including:

  • Keyed Cylinder Locks: Designed for entry from outside with a unique key, these provide enhanced security for glass or metal sliding doors. Options include 5-pin tumbler lock cylinders that are keyed alike for keyed convenience or keyed differently for added security.
  • Thumbturn Cylinders: Allow for quick locking and unlocking from the inside, often paired with a key-operated cylinder on the exterior. Products like the Thumb Turn with Tail Piece Kit are available in multiple colors to match your door hardware.
  • Mortise and Barrel Locks: Mortise locks, such as the vertical slot mortise lock, fit into recessed pockets for a flush, secure installation on metal or wood sliding doors.
  • Specialty Cylinder Options: Including foot bolts and spring-action locks, these add layers of security for patio doors or supplement primary locksets. Consider the Square Spring Action Foot Bolt for additional holding power.
