Service, repair and takeover of access control you already own
Most of what reaches us from a Katy 77491 mailbox is not a request for a brand-new system. Readers are already on the doors and something about them stopped behaving: a card that works on the third swipe, a keypad whose master code left with a manager two years ago, a door that clamps shut when it should release, or a controller that came back from a power blink with half its programming missing. EVOTECH IT LLC handles that class of work every week, much of it on equipment we did not sell.
A service call can mean diagnosis with a meter rather than guesswork, replacing a power supply or a reader, re-terminating wire that was never landed properly, rebuilding a credential database, adding an opening to a panel that still has capacity, or lifting a dead proprietary head end off a building. Just as often the honest answer is that the system is fine — ten-year-old controllers are frequently worth keeping and need nothing more than a battery, a clean ground and terminations that are not twisted together above a ceiling tile.
77491 is a P.O. box ZIP — tell us the door, not the mailbox
Katy uses a small group of ZIP codes for street delivery and a separate pair strictly for post office boxes. 77491 is one of the box ZIPs. Nothing sits inside it physically; it is where your mail lands, not where your hardware is bolted. That reads like trivia until a work order goes out carrying a billing address and a technician stands at a post office counter instead of your failing entrance.
So when you call, hand us two separate facts: the address of the opening, and the address the invoice should follow. A great many Katy companies that keep a 77491 box are physically out along Franz Road, Katy-Fort Bend Road, Highway Boulevard, Kingsland, Pin Oak, or in the flex and warehouse rows tucked behind the interstate frontage roads — several street ZIPs, one shared mailbox. Name the building, the suite, the specific door that is misbehaving, and whether a controlled gate or truck court sits between our van and that door.
The openings we meet in old Katy and the Franz Road corridor
The building stock on this side of Katy is mixed in a way that matters to a technician. The older town core along Avenue D and Highway Boulevard, near the rail corridor and the rice dryers, runs to mid-century masonry storefronts with narrow-stile aluminum entry doors. Those stiles are too thin for many common electric strikes, which is why an inherited installation there so often shows a strike mortised into a frame that cannot really support it.
Move out toward the Franz and Katy-Fort Bend corridors and the picture changes to pre-engineered metal buildings, tilt-wall flex suites and multi-tenant service condos. Hollow metal doors in knock-down frames are the norm, and the frame return is often welded closed or grouted, so new wire means a raceway decision rather than a fish tape. And on the shop side, a controlled entrance almost never belongs on the overhead bay — it belongs on the man-door beside it, with the bay left to its own operator.
Five failures behind most of the service calls we take here
Power first, always. A dying standby battery, a transformer feeding one device too many, or a filtered output drifted out of spec produces symptoms that look exactly like a bad reader. We meter before replacing anything.
Wire and terminations. Staples driven through jacket, Wiegand runs stretched past a sane length, shields left floating at both ends, and splices lying loose above a grid ceiling. Intermittent faults almost always live here.
The door itself moved. Gulf Coast slab movement and seasonal swings pull frames out of square. A strike that no longer lines up with a latch, a closer that stopped shutting the last inch, or a magnet with a gap you can slide a card through are mechanical problems wearing an electronic costume.
Programming drift. Undocumented schedules, expired holiday calendars, a database with no backup, and an admin account tied to a person who left. This failure costs the most to unwind and the least to prevent.
Weather on the reader. West-facing keypads in full afternoon sun, unsealed penetrations that wick rain into a back box, and insects nesting inside a pedestal. Sun, water and pests retire more readers around here than vandalism ever does.
Adopting a system the last company walked away from
Orphaned access control is common in older Katy commercial space. A building changes hands, the integrator folds or stops returning calls, and what remains is a panel in a closet with no documentation, no admin password, and cards in a format nobody can identify by eye. Sometimes the manufacturer still exists and recovery is procedural; sometimes the platform was proprietary and the licensing is simply dead.
Our approach is to document before we recommend. We map every opening, label what is actually wired versus what is only pretending to be, identify the panel and firmware, read the credential format off a working card, and find out whether parts and licences can still be obtained. Then you get a plain answer: recover it, partially replace it, or migrate it. When migration is the honest call, it is staged opening by opening so the building stays secured and operating the entire time.
Staff turnover: issuing, revoking and genuinely auditing credentials
The technical side of access control is easy compared to the human side. Fobs leave in glove compartments. Subcontractors get a credential for a two-week job and keep it three years. A terminated employee walks out at 4 p.m. and the badge is still live the next afternoon because the only person who could disable it was in a meeting.
We set systems up so the ordinary case takes seconds, not a site visit: named credentials rather than a pile of anonymous cards, groups that mirror how your business actually works, time windows that stop out-of-hours entry by people who have no reason to be there, expiring credentials for temporary help, and an administrator who is a role instead of a single person. We will also sit with you and read the event log, which is where the uncomfortable facts live — the back door that opens at 5:40 every morning, or the door that has been propped every Friday since spring.
The exit check we run whether or not you asked for it
There is one part of a service visit that is not optional for us. Before we close anything up, we verify that people can get out. A locked door is a security control in one direction and a hazard in the other, and the mistakes on inherited installations are consistent: a magnetic lock with no release tied to the fire alarm, a request-to-exit sensor aimed at a wall, a push-to-exit button nobody in a hurry would find, a keyed deadbolt added behind an electrified opening, and exit hardware needing two separate actions.
If we find any of that, you hear about it in writing, even when you called about something else entirely. Some of it we correct on the same visit; some involves your fire alarm contractor or the local authority having jurisdiction, and we say so rather than quietly working around it.
What moves the price of an access control service visit
We never publish figures for this work, because the honest range across two openings in the same building can be wide. What the estimate turns on:
- How many openings are involved, and whether they sit on one panel or several.
- Whether existing cable is reusable — sound wire in a usable path is the single biggest saver on a service job.
- The lock type. A surface magnet, a mortise strike and an electrified panic device are three different labor conversations.
- Panel age and parts availability. A supported platform is repairable; a discontinued one may only be replaceable.
- Access to the work — hard ceilings, occupied suites, tilt-wall cores, and openings that must stay in service all day.
- Scheduling, if after-hours work keeps a shop or clinic from losing a day.
The on-site estimate is free and the quote is itemized line by line.
What to have ready before the truck shows up
A little preparation routinely turns a two-visit job into one. Have someone on site who can authorize work and open the electrical or IT closet where the panel lives — that closet is locked more often than the doors we came to fix. List every controlled opening, including the ones that stopped working so long ago people quit mentioning them, and collect any passwords, licence paperwork or old invoices from the previous company even if they look useless.

Frequently asked questions
My keypad beeps but the door never releases. Is that the lock or the controller?
A beep usually means the reader accepted the credential, so the fault is normally downstream: a supply that cannot hold voltage under load, a worn relay, a broken conductor in the lock run, or a strike binding because the frame shifted. We meter at the lock before replacing anything — swapping a keypad on a power problem just moves the symptom.
Will you service a system EVOTECH did not install?
Yes, and it is a big part of what we do in Katy. We document what is there, identify the panel and credential format, and tell you honestly whether it is repairable, partially repairable, or at the end of its supported life. There is no requirement to rip anything out to become our customer.
A former employee never returned a fob. What can be done today?
If the system holds a credential database we disable that one credential immediately and leave everyone else untouched. If it was configured with a pile of unassigned generic cards — unfortunately common — the only sure fix is re-issuing that door group, after which we set it up so the next departure is a thirty-second task.
Do I need a whole new system to unlock doors with a phone?
Not always. Some controllers accept a reader that handles both cards and phone credentials, letting you keep the panel and the wiring and change only the heads. Other platforms will not, and we say so plainly rather than selling a reader that disappoints you.
Our rear door was held open all weekend and nobody knew. Can that be alarmed?
Yes, provided the opening has a door position contact or we can add one. Held-open and forced-open are standard events, and they can trigger a local sounder, an email or a camera bookmark so you have video of the moment rather than a guess.
Can you work outside business hours so we do not shut down?
We schedule evenings and weekends regularly for shops, clinics and warehouses that cannot lose a working day. Say so at booking and it is priced into the itemized quote up front instead of appearing as a surprise line later.
