Key, Keypad or App? Choose How Your Door Works

Compare Two Separate Decisions

First choose suitable physical hardware for the door. Then choose how authorized people will operate it: a key, keypad, card, phone, or combination. “Smart” describes access and connectivity features; it is not a physical-security rating.

Where a product carries the BHMA Certified Secure Home label, read the separate security, durability, and finish grades. Do not transfer one product’s rating to a different model or to the complete door assembly.

Check Fit and Everyday Use

Record the door thickness, existing hardware, clearance, and whether the door closes and latches without force. A binding door needs attention even if you intend to replace the lock.

Consider who will use the entrance and how they can operate it comfortably. In a rental, condominium, or managed building, confirm permission and any master-key or approved-product requirements before buying.

Plan Backup Access

A mechanical key needs no battery, but the key and lock can still be lost, worn, damaged, or jammed. An electronic lock adds battery and account maintenance. Its local operation during an internet outage may differ from its remote features.

Read the exact model’s instructions. For example, the Google Nest × Yale Lock is key-free and has a specified temporary-power procedure. That is not a universal backup method for smart locks.

Decide Who Manages Access

Check who owns the account, how users are added and removed, what subscriptions or hubs are required, and how access will transfer when someone moves out. Removing an app user does not necessarily invalidate a physical backup key.

Activity records describe events the system detected. They do not always prove which person passed through the door, and the available history depends on the model and settings.
