Learn how to choose a patio door lock for sliding glass doors. Compare keyed, keyless, and smart options, and find the right fit for your Andersen door.
Quick answer
For most sliding glass doors, choose a lock that matches your door's existing prep and your daily routine. If you have an Andersen patio door, the Yale Assure Lock for Andersen Patio Doors with Z-Wave Plus offers keyless entry and smart home integration.
Keyed vs. keyless: what fits your routine?
A keyed patio door lock works like a traditional deadbolt: you need a key to lock or unlock from outside. It's simple, reliable, and familiar, but it means carrying an extra key and potentially fumbling in the dark. If you often enter through the patio, a keyless option can be more convenient.
Keyless locks use a keypad or smart technology to let you unlock with a code or your phone. They eliminate the need for physical keys, which is handy for families, renters, or anyone who wants to grant temporary access. The trade-off is battery dependency and a higher upfront cost.
What to check before buying
Not all locks fit all doors. Before you buy, measure the backset (the distance from the door edge to the center of the hole) and the crossbore diameter. Also check the door thickness and the existing prep—some locks require specific cutouts that may not match your current setup.
For Andersen patio doors, the Yale Assure Lock for Andersen Patio Doors is designed to fit the specific prep of many Andersen doors. This reduces installation guesswork, but you should still verify your door model and prep to ensure compatibility.
Decision rules for choosing a patio door lock
- If you want keyless convenience: Choose a keypad or smart lock like the Yale Assure Lock for Andersen Patio Doors. You'll get code entry and, with Z-Wave Plus, integration with your smart home system. Check if your door has the required prep for the lock you choose.
- If you prefer a physical key: Stick with a keyed lock. It's straightforward and doesn't depend on batteries, but you'll need to manage keys for everyone who needs access. Make sure the lock's backset matches your door's existing hole spacing.
- If you have an Andersen patio door: Consider the Yale Assure Lock for Andersen Patio Doors. It's designed for Andersen doors, which simplifies installation and ensures a better fit. Verify your door model and prep before ordering to avoid returns.
