Keyed cylinder locks are designed to secure doors, windows, and sliding patio entrances by using a precision-engineered cylinder core and pin system that only the matching key can turn. Commonly used in both residential and commercial settings, these locks are a preferred solution for upgrading or replacing worn, damaged, or outdated cylinders without changing the entire lock hardware.

How Keyed Cylinder Locks Work

Inside the cylinder, a series of pins and springs align with the cuts of the inserted key. When the correct key is used, it lifts the pins to the precise height needed for the cylinder plug to rotate, engaging or disengaging the lock. This design allows for easy rekeying or replacement, making it a cost-effective option when security needs change.

Types and Applications

You'll find keyed cylinder locks in a variety of types, including single-cylinder, double-cylinder, and thumbturn options. They are suitable for sliding patio doors, hinged entry doors, and specialty windows. Choose between keyed alike cylinders, where one key operates multiple locks, or keyed differently, where each lock has its own unique key.

  • Pin tumbler cylinders, including popular 5-pin designs
  • Compatible with AmesburyTruth systems and leading door brands
  • Options for Schlage and Weiser keyways
  • Durable finishes and sizes for residential and commercial use

Replacement and Installation Tips

Replacing a cylinder lock is straightforward, usually requiring only a screwdriver and the correct replacement part. Always check the length and profile of your existing cylinder to ensure compatibility. If you are matching keys across multiple locks, look for keyed alike cylinders. For increased security or unique access, select keyed differently models.

AmesburyTruth cylinders are built for long-lasting performance and fitment with a wide range of North American window and door products. Popular applications include patio door handles, aluminum storefront doors, and commercial locksets. When in doubt, compare your cylinder's tailpiece, body diameter, and keyway to options like the Schlage key cylinder or Weiser-compatible American cylinder.
