Adding a smart lock? Decide what stays on the door first

Keeping the key changes the shopping list

Yale's Approach is an example of an interior retrofit: it attaches over an existing compatible deadbolt and retains the outside key. Yale describes compatibility with most single-cylinder deadbolts, not every lock. Send the existing lock's model and photos of both sides before buying a retrofit kit.

If you want a new exterior keypad and lock, compare complete replacement packages. Schlage's Encode Plus, for example, has exterior and interior bodies, specified door dimensions and its own physical backup key. Do not assume that buying a replacement preserves your current key or matches another door's lock.

State any requirement to preserve the exterior appearance. If this is a rental or managed property, confirm permission for the proposed change before ordering. Existing trouble closing or locking the door should also be included in the assessment.

Separate keypad entry from remote access

A code that works while you stand outside is different from unlocking through an app while away. Schlage lists built-in Wi-Fi and a 2.4 GHz network requirement for Encode Plus. That is a model-specific example; check whether your selected lock needs a separate bridge, module or compatible home system for the features you want.

Schlage's Encode support guidance says keypad or physical-key operation remains possible without Wi-Fi, while some connected features are unavailable. Do not treat a successful keypad test as confirmation that remote access is ready.

• List the exact model and every accessory included in the package.
• Name the app or existing home system you want to use.
• State whether remote control, temporary guest access or only local entry matters to you.
• Keep network passwords, access codes and setup credentials out of the project-request photos.

Plan for a flat battery or unavailable phone

Ask the installer to show the selected model's battery warnings and backup entry method. Encode Plus specifies a low-battery indicator and physical backup key; other models may use different arrangements. Learn your actual model's procedure rather than relying on a general claim that smart locks work during an outage.

Decide who will respond to battery alerts and where an authorized person can access the backup method. Do not include that location in the installation inquiry.

Finish with a handoff you can repeat

Ask whether the proposal includes only mechanical fitting or also supported app setup and a demonstration of the agreed features. Use an account you control, and enter its credentials yourself. Have the installer demonstrate normal locking, unlocking and any promised connected feature before calling setup complete.

Send Coast & Craft the product link, existing hardware photos and the features you want reviewed. Hardware suitability, any door adjustment and the accepted setup work need confirmation before the visit.
