Smart locks are genuinely useful in some situations and oversold in others, and an honest locksmith should tell you which is which before selling you anything. The convenience of a code instead of a key is real, especially for rentals and busy households, but a lock is still a mechanical thing bolted to a door, and no amount of connectivity changes the physics of the door and frame behind it. Half Off Locksmith installs and services keypad and smart entry across Broward County, and this page lays out where the money is well spent and where it is not.
Keypad-Only Versus Wi-Fi Connected
The first decision is whether you actually need the lock online. A keypad-only lock lets you and others enter with a code instead of a key, and that alone solves most of what people want: no hidden spare, no lockout from a forgotten key, easy access for people you let in. A Wi-Fi or connected lock adds remote control and a phone app, so you can unlock from anywhere, get notified when someone enters, and change codes remotely. That is worth it if you genuinely manage access from a distance, such as a rental you do not live at. For a primary home where everyone is already there, the connected features often go unused while the added complexity stays.
What Happens in a Power or Wi-Fi Outage
People assume a smart lock dies when the power goes out, and mostly it does not, because these locks run on their own batteries rather than house current. What a Wi-Fi outage does take away is the remote features: the app cannot reach the lock, so remote unlocking and notifications stop until the connection returns. The keypad and any local codes usually keep working through it. This is exactly why the connected layer should be treated as a convenience, not the thing you depend on to get in the door, and why a working local method matters more than the app.
Battery Life and the Mechanical Key Backup
Batteries are the real maintenance item on any electronic lock. Most give plenty of warning with low-battery beeps or app alerts, and swapping them is a two-minute job, but ignoring those warnings is the most common way people lock themselves out of a lock that was supposed to prevent lockouts. Many models keep a mechanical key cylinder as a backup for a dead battery, and if yours does, keep a physical key somewhere you can reach it. A model with no mechanical backup puts everything on the batteries and the electronics, which is a trade-off worth understanding before you buy rather than after.
Only as Strong as the Deadbolt and Strike Behind It
This is the point that gets lost in the marketing. A smart lock's electronics do nothing to stop a door from being kicked in, because a forced entry defeats the frame, not the keypad. If the deadbolt is a cheap grade and the strike plate is screwed into a thin jamb with short screws, a two-hundred-dollar smart lock is guarding a door that a determined shove will open regardless. Reinforcing the strike and using a solid deadbolt does more for real security than any feature on the keypad, which is the same lesson that applies to ordinary locks on our house lockouts and rekeying page.
Retrofit Interior Units Versus Full Replacement
There are two broad ways to add a smart lock. A retrofit unit replaces only the interior thumbturn and drives your existing deadbolt, so the outside of the door looks unchanged and you keep your current keyed cylinder. That is a clean option when you like your existing lock and just want app or auto-lock control. A full replacement swaps the entire lock, inside and out, and is what you need when you want a keypad on the exterior or when the old hardware is worn out. Which one fits depends on your door and what you actually want to change.
Door Prep, Backset, and Bore Fit
A smart lock only works if it physically fits the door. The bore is the round hole the lock passes through, the backset is the distance from the door edge to the center of that hole, and both have to match the lock or it will not seat correctly. Doors also vary in thickness, and a lock forced onto the wrong prep will bind, fail to latch cleanly, or wear out fast. Getting these measurements right is ordinary work for a locksmith and is the difference between a lock that operates smoothly for years and one that jams within months.
Guest Codes for Rentals, and South Florida Heat
The strongest case for keypad entry is short-term rentals and homes with cleaners or service people coming and going. Individual codes let you give a guest or a cleaner their own code, then change or remove it after they leave, so access ends when the stay ends without collecting or rekeying anything. That control is the real value of these locks. One caution specific to our climate: exterior keypads live in relentless heat, sun, and humidity, and cheaper units degrade under it, with buttons wearing or moisture working into the electronics. Choose a unit rated for outdoor exposure and expect an exterior keypad here to work harder than one up north. For managing access across many doors or units at once, our commercial locksmith and master key systems page covers larger setups.
