Smart Lock Install: 4 Things to Check Before You Buy

A smart lock is a great upgrade, but the most common problems happen before it's ever installed — buying one that doesn't fit your door. Four checks save the headache: measure the door, confirm the deadbolt type, set individual codes, and test the backups.

How do I know a smart lock will fit my door?

Measure your door thickness first. Most smart locks fit standard doors (around 1⅜ to 1¾ inches), but thicker or thinner doors need an adapter or a different model. Also check the backset (the distance from the edge to the bore hole) and the bore hole size. A two-minute measurement prevents a returned lock.

Does my existing deadbolt matter?

Yes. Confirm your deadbolt type matches the lock you want. Some smart locks replace the entire deadbolt; others (like retrofit models) keep your existing deadbolt and exterior key and only swap the interior thumb-turn. The retrofit type is easiest if you like your current keys — just verify compatibility with your hardware.

Should everyone share one code?

No — set a unique code per household member (and temporary codes for guests, dog walkers, or contractors). Individual codes let you see who came and went and revoke one person's access without changing everyone's. Shared codes defeat half the point of a smart lock.

Why test the backup options?

Because batteries die and tech glitches. Test the backup key or battery option before you rely on the lock — know where the physical key is (most keep one), how to jump-start it with a 9-volt battery if it dies, and how the manual override works. Getting locked out of your own smart lock is avoidable.

Record codes and backups

Keeping track of codes and the backup-key location keeps the household running smoothly. Okoniq Property Hub stores your device and access notes with your home maintenance records in one private place. Pair a smart lock with a doorbell camera for full entry coverage.

Frequently asked questions

Are smart locks secure?

Reputable smart locks use strong encryption and are as secure as — often more than — a traditional lock, with the bonus of access logs and remote control. Choose a known brand and keep its app updated.

What happens if the batteries die?

Most warn you well in advance and offer a backup: a physical key, an external battery contact, or both. Replace batteries on schedule and keep a backup key accessible.
