Smart locks have moved from novelty to normal. We install a lot of them, and we like them for the right customer on the right door. We also take a fair number of them off doors where they were the wrong answer.
Here is an honest look at what you gain, what you give up, and what to check before you buy.
What a smart lock is genuinely good at
Getting rid of shared keys
This is the real win, and it is bigger than most people expect. A cleaner, a dog walker, a contractor, a family member — each can have their own code, and you can revoke one without touching the others. No spare under the mat, no key that has to come back, no wondering who still has one.
Knowing when the door was used
An access log tells you the kids got home, or that the cleaner came Tuesday rather than Wednesday. For rental property and small businesses this alone often justifies the cost.
Auto-locking
An unlocked deadbolt provides nothing. A lock that throws itself after a set delay quietly fixes the most common security failure in any home — the one where somebody simply forgot.
What people underestimate
Batteries
Every smart lock runs on batteries, and they die. Good models warn you well in advance and most provide a backup — a physical key override, or external contacts you can touch a battery to. Know which one your lock has before you are standing outside in February finding out. If a lock has no override at all, that is worth knowing up front.
The door still decides the outcome
A smart lock is a smarter way to operate a deadbolt. It is not a stronger deadbolt. Check the ANSI/BHMA grade on the lock body, and reinforce the strike plate, exactly as you would with conventional hardware. Connectivity does not reinforce a door frame.
Alignment gets less forgiving
You can muscle a stiff mechanical deadbolt closed. A small motor cannot. A door that has settled, swollen, or was never quite right will produce a lock that jams, grinds and drains batteries. If your deadbolt currently needs a shove, fix the alignment first — otherwise you are buying a motorised version of an existing problem.
Keypad wear
On a keypad used daily for years, the pressed buttons can become visibly worn — which narrows the guesswork for anyone paying attention. Rotate codes occasionally. Models with a touchscreen, or ones that let you pad your code with extra digits, sidestep this.
Choosing a type
- Keypad only, no connectivity. Codes, no app, no network. Reliable, inexpensive, nothing to maintain. For most people who just want to stop handing out keys, this is genuinely enough.
- Bluetooth. Works from your phone at the door. No hub, no cloud dependency, but also no remote access from work.
- Wi-Fi or hub-connected. Full remote control, logs and notifications. More to set up, more to keep updated, and it depends on your network being up.
- Retrofit interior-side units. Motorise your existing deadbolt from inside, keeping your current exterior hardware and keys. A good option for renters, or when you want to keep a matching finish.
Before you buy, check these
- Your door thickness and backset. Most locks fit standard doors, but not all doors are standard.
- Whether your door is metal, has a glass insert, or is a narrow-stile storm door. These often need specific hardware.
- Whether the deadbolt currently throws smoothly with the door closed. If not, fix that first.
- What happens when the batteries die. Key override, external contacts, or nothing?
- Whether the manufacturer still supports the model with firmware updates.
Our actual recommendation
Put a good smart lock on the door you use most — usually the one from the garage or the back door — and keep quality conventional deadbolts elsewhere. You get the convenience where it matters daily, without multiplying the number of things that need batteries and updates.
And whichever you choose, get the frame right. A reinforced strike plate with three-inch screws does more for your security than any feature list.
If you would like a straight answer about whether your doors are good candidates, we are glad to take a look before you spend anything.
