Doorbell Camera and Smart Lock Setup in Katy, TX 77494
Almost nobody buys a keypad deadbolt because they want a keypad. They buy it to stop handing out keys — to a housekeeper, a dog walker, a teenager who loses them, a contractor who needs the house for one afternoon in November. Read that way this is not a hardware purchase. It is a decision about who gets in, on what schedule, and what happens on the day none of the electronics are available.
Write the access list before anyone opens a box
Every household we work with in Katy turns out to have four categories of person, and each one implies a different feature. Getting this on paper first is what stops you buying a lock that cannot do the thing you actually needed.
- The household. Permanent credentials, phone plus a code plus a key. These people need the lock to be boring and to never ask them for anything.
- Recurring service. A cleaner every other Tuesday, a lawn crew, a pool service. They need a code that only works inside a window, and a record that says it was used.
- One-off access. An appliance delivery, a trades visit, a neighbour collecting a parcel. They need something that expires on its own, because a code you have to remember to cancel is a code that never gets cancelled.
- Emergency. A family member who lives elsewhere and might need to get in when nobody is answering a phone. This is the one people skip, and it is the one that has to work with a flat battery and a dead router.
Hardware that satisfies all four is not exotic or expensive. Hardware chosen without the list usually satisfies two of them.
The eight-foot double entry and where the bolt actually lands
A large share of the bigger plans across Cinco Ranch, Seven Meadows, Grand Lakes, Tamarron and Firethorne have a double front entry rather than a single slab, and that changes the conversation in a way most product pages never mention.
On a double entry only one leaf is in daily use. The other is held closed by flush bolts that shoot into the head and the threshold, and the active leaf’s deadbolt does not throw into a jamb backed by framing at all — it throws into the astragal, the vertical closing strip carried on the edge of the inactive leaf. Three things follow from that geometry:
- The resistance of the whole entry is set by the flush bolts and the astragal, not by the grade stamped on the deadbolt. Flush bolts that are painted in place, short, or not fully seated in the threshold are the actual weak point, and they are invisible with the door shut.
- The pocket in an astragal channel is shallower than a framed jamb pocket. A replacement deadbolt whose bolt sits at a slightly different projection can bottom out or fail to clear, which is a five-minute check on site and a wasted afternoon otherwise.
- The interior escutcheon of a motorised lock is deeper than the thumbturn it replaces, and on a double entry it has to clear the astragal’s interior flange when the inactive leaf is closed.
None of that makes a keypad impossible on a double door — we fit them regularly. It does mean anyone quoting one without looking at the astragal is quoting a guess. We check flush-bolt engagement top and bottom as part of the same visit, because a smart lock on a leaf whose partner is not properly secured is a false sense of security rather than a real improvement.
The construction key, the keyed-alike set, and what your neighbours’ trades still carry
Production builders run a construction keying system so that every trade on the street can use one key during the build, and the homeowner’s key retires it on first use. That part works as designed. What people miss is what happens after handover.
In a typical Katy build the front door, the garage man-door and the back door are keyed alike to a single cylinder, and a fair number of hands touched that set between framing and closing. Replacing the front door cylinder with a smart deadbolt breaks the set — which sounds like progress, and is in fact the moment your least-controlled entry becomes your only key-operated one. The back and side doors still open with the original key, held by whoever still has it.
So we treat rekeying as part of this job rather than a separate trade call. Depending on the hardware you already own, that means either rekeying the remaining cylinders to a fresh key, or keying everything to match the new lock’s own cylinder where the platform allows it. Either way you end the day knowing exactly how many working keys exist and who has them, which is the whole point of the exercise.
Name every code, or the log tells you nothing
The single most useful configuration habit costs nothing: one code per person, named for that person, never a shared household code. A shared code turns the access log into a list of timestamps with no subject. Named codes turn it into a record you can actually act on — the cleaner arrived at 9:40, the code you gave a contractor in March has been used in June, the teenager did get home before the film started.
Schedules do the rest of the work. A recurring service code that is only live on the days that service comes removes an entire class of worry without anybody having to remember anything. An expiring code for a one-off visit closes itself. And any code that has been read aloud over a phone should be treated as spent and rotated afterwards, because a code you never rotate is simply a key you can never get back.
One detail we check that most installs skip: the doorbell’s recordings and the lock’s access log are two separate records kept by two separate devices, and they only line up if both devices agree what time it is. We verify that on the day, so that when you do need to put a clip next to an entry event, the two actually correspond.
Four failures, four ways in
This is the section we care most about, because every emergency call we get about smart locks traces back to a household that never tested one of these four.
| What has failed | What still works | What we set up on the day |
|---|---|---|
| The batteries are flat | The mechanical key, the interior thumbturn, and on many models an external contact that accepts a battery to power the motor long enough to open | A physical key kept off the property — with a neighbour, in a vehicle, at a relative’s house — never inside the door it opens |
| The internet is down | The keypad, the key and any local hub control. Remote unlock, remote status and notifications do not | At least one credential that never touches the internet, and a household that has used it once |
| The router was replaced or the network name changed | Everything local. The lock and the doorbell both need re-enrolling before remote features return | Written credentials and the re-join steps left with you, so a router swap is not a service call |
| A phone is lost | Codes and keys are unaffected | A second administrator account on a different phone, so access can be revoked without the missing device |
We test the key override with the cells removed while we are standing there. It takes two minutes and it is the only way you will ever be sure the backup you are relying on actually turns.
The garage man-door is usually the real problem
On the standard Katy plan the front door is the most watched opening in the house and, quite often, the least interesting one. The door that deserves attention is the man-door from the garage into the mud room or the side yard. It is out of sight of the street, frequently inside a fenced side gate, fitted with the cheapest deadbolt in the package, and very often held by short screws into the jamb alone. It is also the door that gets left unlocked, because everyone treats the garage as inside the house.
The back of the house is usually a slider, and a slider is not a deadbolt problem — it wants a track block, a secondary latch and, if you want to know when it opens, a contact sensor rather than a lock.
So our honest ordering, when a household asks where the money should go, is: correct the man-door strike and screws first, decide whether that door wants a code of its own second, and treat the front door keypad as the convenience feature it genuinely is. We would rather tell you that during a free estimate than sell three locks and leave the weakest opening as it was.
What you are left with when we drive away
The install itself is the short part. What matters is the state of the house afterwards, so the visit ends with a fixed checklist: every code named and written down for you; the key override tested with the batteries out; auto-lock set to a delay that matches how your household actually uses the door, rather than a default that will lock a child out in the back garden; the doorbell and the lock both showing the correct time; the administrator account in the name of the person who should hold it; and all the keys we handled returned to you with a straight answer about how many now exist.
We also leave the doorbell’s own settings in a state you can understand, and we will tell you plainly if the Wi-Fi at your front elevation is the weak link rather than anything we installed.
What moves the scope, and what brings us back
Scope is driven by: how many openings are in the job; whether the entry is a single slab or a double with an astragal; whether rekeying the remaining cylinders is included; the condition of the existing strikes; whether an architectural committee has a say on exterior finishes in your section; and whether the front elevation has usable wireless coverage. EVOTECH quotes after looking at the doors — the on-site estimate is free, the quote is itemised, and there is never a figure attached to a job nobody has seen.
The four callbacks we see most
- Auto-lock set aggressively in a house with young children and a back garden.
- One shared code issued to six people and never changed.
- A lock commissioned onto a strike that needed correcting first.
- No key anywhere outside the building it opens.

Frequently asked questions
We have a double front door. Can we still have a keypad deadbolt?
Usually yes, and we fit them on double entries regularly. The checks that decide it are the depth of the pocket in the astragal, the projection of the replacement bolt, and whether the deeper interior plate clears the astragal flange when the inactive leaf is shut. All three are quick to verify in person and impossible to verify from a photograph, which is why we look before quoting.
Should I rekey the rest of the house at the same time?
We think so, and here is the reasoning rather than a sales line. Your doors were almost certainly keyed alike at handover, and the number of people who have handled that key during construction is not small. Putting a keypad on the front while the side and back still answer to the original key does not reduce the number of uncontrolled keys — it just changes which door they open. Doing both together is the only version of this that leaves you with a genuinely known set.
How many codes is too many?
The limit is not the lock, which will hold far more than a household needs. The limit is whether you still recognise every entry in the list. Our rule of thumb is that if you cannot name every code from memory, you have too many — so prune the expired ones when a service ends rather than leaving them dormant. Dormant credentials are the ones nobody thinks to revoke.
My teenager keeps leaving the door unlocked. Is auto-lock the answer?
It is the obvious answer and it needs one adjustment. Auto-lock closes the gap, but a short timer in a house with a back garden and children will eventually lock somebody out during a barbecue. We set the delay against how the household really moves through the door, make sure everyone who uses the house has their own code rather than relying on a phone, and check the fallback so that being locked out is a two-minute inconvenience and never a locksmith call.
If we sell the house, does the next owner inherit our codes?
Only if you leave them there. A lock should be factory reset and re-enrolled to the new owner’s account at handover, which clears the codes and removes your phone’s authority over the door. Since the mechanical cylinder should also be rekeyed at that point, this is worth doing as one task. We are happy to do it as a standalone visit when a Katy property changes hands.
Can you put one on the garage man-door instead of the front?
Yes, and for some households that is the better first move. It is the door the family actually uses, it is out of public view, and it is typically the weakest opening in the package the builder supplied. We would still correct the strike and the screw length into framing while we are there, because a motorised lock on a poorly anchored strike inherits every weakness of the original fitting.
