However, some manufacturers may have variations, so it's essential to measure your existing knobs before purchasing replacements.

Types of Exterior Door Knobs

Different types of exterior door knobs exist, such as keyed knobs, privacy knobs, and passage knobs. Keyed knobs provide security, while privacy knobs are suitable for bedrooms or bathrooms. When selecting new knobs, ensure they match your door's intended use and locking system. Additionally, consider the design and finish to maintain a cohesive look throughout your home.

Installing exterior door knobs can be a DIY project if you have basic tools and a little patience. Remove the old knob by unscrewing it, carefully follow the manufacturer's instructions for the new knob, and ensure everything is aligned correctly. Don’t forget to test the knob’s functionality before securing it fully.
