Smart Lock Installation
You have just taken possession of the house and the previous owners handed over a keypad deadbolt with a code nobody wrote down and an app account you cannot get into.
In plain words
A smart lock fitted by a locksmith keeps a way in that works when the battery or network fails, a mechanical key on many models or an external battery contact on key-free ones. Most keypad deadbolts keep a conventional keyway, rekeyed during the visit so a fresh key operates it and the old one retires. Some models instead add small outside terminals where a nine-volt battery can wake a dead lock long enough to enter a code. The technician tests whichever route the model provides, shows the low-battery warning, and explains what the lock does if the internet goes quiet.
How the visit goesThe deadbolt is a stiff double-cylinder model that needs a key from both sides, and in the dark hallway finding it is a nuisance. You want a thumb-turn inside, a keypad outside, and a door that locks itself behind you.

How the visit goes
Measuring the door and its holes
Smart locks are built around the standard residential preparation, so the locksmith measures before choosing. Door thickness is usually between 35 and 45 millimetres; thicker doors need an extension kit and very thin ones may need a different model. The large cross bore for the cylinder, the smaller edge bore for the bolt and the backset from the door edge to the centre of the hole are each checked against the new lock's range. A lever set also needs the handing confirmed. Steel and fibreglass doors, doors with a mortise pocket from an older lock, and doors with glass close to the handle each change what will fit and how it is mounted.
Fitting the bolt, the body and the strike
With the door ready, the mechanical parts go in first. The new bolt is set to the door's backset and slid into the edge bore with its face plate flush. The outside assembly, keypad or touch surface, is placed with its cable fed through the cross bore, and the inside mounting plate is fixed so the two halves clamp the door without twisting. Screws are driven by hand rather than with an impact driver, because an over-tightened housing binds the motor. The interior unit is seated on the plate and the tailpiece aligned so the thumb-turn and the motor share the same travel. A reinforced strike with long screws replaces the light original.
Knowing what works when the internet is out
You leave with a clear picture of what the lock does on its own. On most models the keypad, the key and any fob keep working with no network at all, because they talk to the lock directly; what needs the internet is checking or changing the lock from far away and receiving alerts. Codes and schedules stored in the lock carry on through a router reboot or a power cut. The locksmith will have named which functions on your specific model depend on Wi-Fi or a hub, so a quiet evening with no connection is an inconvenience for the app and nothing more for the door.

What affects the quote
Supplying the lock yourself
If you have already bought a lock, the quote covers fitting and setup only, with a note on whether the chosen model suits your door; if the locksmith supplies it, the hardware is listed alongside.
Number of doors
A single front door is the base case. Adding the back door, the garage entry or a side door, whether each gets its own smart lock or is rekeyed to match the override key, extends the visit accordingly.
Reinforced strike and security hardware
A box strike with long screws is part of a sound installation and is listed as a part. A wrap-around door reinforcer or a hinge upgrade is offered where the door would benefit, as a separate option.
What to have ready
- Which other doors should share the same key or the same system?
- Is there already a keypad or app lock on the door, and who set it up?
- Do you already have a specific lock in mind or in hand?
Smart Lock Installation: questions
QuestionsCan I install a smart lock myself?
Many people do, and on a door that already closes perfectly with the standard holes the instructions are manageable. Where a locksmith earns their place is everything around the box: recognizing a bolt that drags before it wears out a motor, enlarging or filling holes cleanly, fitting a reinforced strike, rekeying the override so the old key retires, and setting up the account and codes in a way that is easy to manage later. If you have started and hit a snag, that is a normal call too.
Do I need a hub or a bridge?
Only if the model you choose uses one to reach the internet. Some locks have Wi-Fi built into the interior unit and connect straight to your router. Others save battery by using Bluetooth at the door and a small plug-in bridge nearby to relay to the network. Locks designed for a home hub join whatever hub you already run. The locksmith checks signal strength at the door itself and recommends the arrangement that keeps the lock reliably connected.
Is a smart lock as secure as a regular deadbolt?
The part that resists force is the same: a steel bolt, a solid strike with long screws and a door that closes true. Smart deadbolts meet the same residential hardware standards as mechanical ones, and a reinforced strike goes in regardless of which you choose. Where a smart lock adds is on the human side: codes that can be revoked and a door that locks itself, plus, on a key-free model, no keys to copy or lose. Good habits, such as unique codes and updates, keep the electronic side tidy.
