A keypad or fingerprint lock is only as good as its installation. The hardware matters, but so do door prep, alignment, batteries, codes and testing. Here is what a careful job looks like, step by step, and what to ask before anyone drills into your door.
Start with the door, not the lock
Before any lock goes on, we look at the door. Is it solid, hollow, wood, metal or fiberglass? Is it straight, and does it close without rubbing? A smart lock cannot fix a door that sticks or sags, and it will only make the problem more annoying.
We also check the existing holes. Most residential doors have one large hole for the lock and one smaller hole for the latch. A good installation uses those holes cleanly, or enlarges them with the right tools instead of forcing something to fit.
Backset, bore and door prep
Backset is the distance from the edge of the door to the center of the lock hole. The two common sizes are different, and many locks include an adjustable latch to handle both. Measure first, and do not assume.
Door prep means making sure the bore, the edge hole and the strike area are clean, square and the right size. Rough or oversized holes lead to a loose lock, a wobbling keypad and a latch that does not line up. Taking a few extra minutes here saves trouble for years. For more on door work, see our lock installation page.
Alignment of the latch, strike and keypad
Alignment is where good installers earn their keep. The bolt has to slide cleanly into the strike on the frame, with no scraping and no force. If you have to lift or push the door to lock it, the alignment is off.
The keypad side and the interior side also have to be mounted straight and drawn together evenly, with the cable routed without pinching. The photo below shows a keypad smart lock with a fingerprint reader on a door, and a technician testing the installation, which is exactly the kind of check we mean.
Batteries and power
Almost every keypad and smart lock runs on batteries. Use fresh, good quality batteries of the type the maker recommends, and install them with the right orientation. Cheap or mixed batteries can cause odd behavior, such as a lock that works for a few days and then stops.
Learn how your lock warns you when power is low. Most give a signal, a light or a sound, well before the batteries die. When you see it, change them promptly. Keep spare batteries somewhere other than the lock itself, and tell everyone in the household where they are.

Codes, users and the backup key
Set up your own codes right away and remove any starter code the lock came with. Choose codes that are not simple patterns or dates that someone could guess. If your lock supports separate codes for different people, use them, so you can remove one person later without changing everyone else.
Always keep a backup key. Many keypad deadbolts still have a regular key cylinder, and that is your safety net if the electronics fail or the batteries run out. The photo below shows a keypad deadbolt on a white door beside a lever handle, a common pairing on many front doors. Keep the key somewhere safe, not under the mat.

Testing before we leave
A proper job ends with testing, not just tightening the last screw. We lock and unlock the door from the inside and outside, using the keypad, the fingerprint reader if there is one, and the backup key. We open and close the door several times to confirm the latch moves cleanly.
We also test with the door closed hard, then softly, because a lock that works in one case but not the other is not set correctly. Only then do we walk you through the settings. The photo below shows a keypad smart lock installed on a white door with a lever, and a technician’s tool bag on the ground, which is how a finished job often looks.
If you ever need your existing hardware reworked rather than replaced, we also handle deadbolt installation and repair.
Florida humidity and weather
South Florida is hard on electronics and metal. Humidity, salt air, heavy rain and strong sun can all shorten the life of a lock that is not made or installed for it. Choose a model with a finish and seals suited to outdoor exposure, especially on doors that face the weather.
Installation matters here too. A tight, well sealed mounting keeps moisture away from the keypad and the battery compartment. Check the lock after storms, wipe it down with a soft cloth, and avoid harsh cleaners. We serve homes and businesses across Broward, Miami-Dade and Palm Beach counties, and we see how the climate affects hardware every day.
Common questions
Can I put a keypad lock on any door?
Most standard residential doors can take one, but the door needs the right bore, edge hole and thickness, and it must close properly. Very thin, damaged or unusual doors may need extra work. We check the door first and tell you plainly if anything has to be adjusted. Ask us before you buy.
What happens if the batteries die?
Most locks warn you well before that happens, with a light or sound. If they do run out, many models keep a regular key cylinder as a backup, or let you power the lock briefly from outside. That is why we always recommend keeping a backup key in a safe place. We will show you how yours works before we leave.
How many codes should I set up?
One code per person is a good approach if your lock allows it, so you can cancel one without disturbing the rest. Avoid simple patterns, birth dates and the starter code. Change codes when someone no longer needs access, such as a former tenant or contractor. Keep a short written list of who has which code.
Will Florida humidity damage a smart lock?
It can shorten the life of a lock that is not built or installed for outdoor conditions. Choose a model with a suitable finish and good seals, mount it snugly, and keep it clean. Checking it after heavy storms is a smart habit for any exposed door. Cleaning and a regular look now and then go a long way.
Should I still keep a regular key?
Yes. Electronics can fail, batteries can run low and phones can die. A regular key is your simple, dependable backup. Keep it in a safe place that is not obvious to a stranger, and make sure someone you trust knows where it is. It costs nothing to keep and can save a long wait.
