Katy Access Control Contractor for Takeovers, Upgrades and Ongoing Service

Most Katy calls start with a system already on the wall

Katy has grown fast enough that a lot of its commercial space has already changed hands. Retail pads near the Grand Parkway and I-10, office condominiums along the main arterials, the plazas around Katy Asian Town and the warehouse buildings stretching west toward Brookshire all turn over tenants, and the access control system usually stays behind when the old tenant or the original installer leaves.

So a typical Katy call is not a request for a new system. It sounds more like one of these:

• Nobody can add or delete users because the administrator password left with a former manager.
• Doors unlock an hour early or late every spring and fall since the last time change.
• A former employee’s card still works, and there is no way to tell whose else does.
• New cards can only be bought through a dealer who no longer returns calls.
• The software runs on an aging PC under the front desk, and that PC is failing.
• A power supply is beeping, or a battery case has visibly swollen.
• The door opens for a card but sounds an alarm every time someone walks out.

Each of those can be fixed. The first job is finding out what is actually installed.

The takeover audit: twelve checks on a system we did not install

1. Controller identity: make, model and firmware, and whether the manufacturer still supports it.
2. Administrator access: whether a login can be recovered, or whether only a factory reset remains, which erases the cardholder database.
3. Software host: a local PC, a server or a cloud platform, and whether that PC is still getting patches from its maker.
4. Credentials: 125 kHz proximity, 13.56 MHz smart cards or a mix, and whether you can order more in that format yourself.
5. Reader wiring: Wiegand or OSDP, and the condition of cable at exterior readers after years of sun and rain.
6. Lock hardware: each door’s lock type and its behavior without power, compared against the fire rating label on the frame.
7. Request-to-exit devices: present, working, and wired either to release the lock or only to suppress the forced-door alarm.
8. Door position switches: present, aligned and reporting, or jumpered out by someone tired of the alarms.
9. Power supplies: output voltage under load, fuse condition and battery date codes.
10. Fire alarm release: proven with the fire alarm company, not assumed from a wire in the cabinet.
11. User list: active credentials versus actual people, shared PINs, and cards belonging to former staff.
12. Schedules: holidays, time zone, daylight-saving handling and any door left on permanent unlock.

You receive the findings in writing with a recommendation for every door: keep, repair or replace. Often the right answer is a new controller that reuses the existing readers and cable. Sometimes the wiring is sound but the head-end is past the end of its supported life, and occasionally the audit shows the system simply needs cleanup, not replacement.

Leaving 125 kHz prox cards behind without a lockout day

Older Katy systems almost all run on 125 kHz prox. Those cards answer any reader that asks with the same unprotected ID every time, and a cheap handheld copier can capture that ID from a pocket or purse and write it onto a blank fob in seconds. That matters most where a building runs unattended, such as a 24-hour fitness studio off a Katy arterial or a medical office that sits empty overnight.

Encryption is what fixes the problem, not frequency alone. Some older 13.56 MHz card families use cryptography that was broken years ago, so the goal is a current encrypted credential or a mobile credential on the phone. A migration that keeps the business running looks like this:

1. Confirm the controller can accept the longer card formats that newer credentials use. Older panels limited to 26-bit input sometimes need replacing as part of the change.
2. Swap each reader for a dual-technology model that accepts the legacy prox card and the new credential at once.
3. Issue new credentials one department or shift at a time, deleting each old card as its replacement is handed out.
4. Watch the event log for prox reads until they stop.
5. Turn off prox reading in the reader configuration so a cloned card is refused everywhere.

Mobile credentials suit many offices, but keep a card option for staff who will not install an app on a personal phone and for the day a phone battery dies at the door.

A maintenance calendar that keeps doors off the emergency list

These are starting intervals. A high-traffic warehouse man door or a gym entry cycling hundreds of times a day may need closer attention than a records room opened twice a week.

Administrative habits that turn into service calls

Wiring is only half of what brings a contractor back. On Katy systems we service, these management habits cause as many visits as failed hardware:

• Shared keypad codes. The log records a code rather than a person, and changing it means retraining everyone.
• One access level for everybody. Every employee reaches every door at all hours because nobody designed levels at installation.
• No holiday schedule. The front door unlocks on its weekday schedule on Thanksgiving morning with nobody inside.
• Timed unlock without first-person-in. After a storm closure, doors still open at eight o’clock for an empty building. First-credential unlock keeps them locked until an authorized person actually badges in.
• Silencing instead of fixing. A held-open alarm is disabled when the real problem is a closer that no longer pulls the door shut.
• Borrowed power. A new door is added by splicing its lock onto another door’s output, overloading a supply sized for one.
• A single administrator. Only the installer or one manager can log in, so the business is locked out of its own system when that person leaves.

What EVOTECH does on a Katy call, and what sets the price

1. Phone triage. We ask for photos of the controller label, a reader and a card, which often identifies the system before we arrive.
2. On-site audit. The twelve checks above, door by door.
3. Written findings and an itemized quote, separating what must be fixed now from what can wait.
4. Phased work. Doors are converted in an order that keeps the business open, with after-hours visits where a door cannot be down during the day.
5. Handover. Administrator accounts in your name, a door list, wiring notes and a database backup.
6. Ongoing service, if you want it, on the maintenance calendar you choose.

What moves the number:

• Whether the existing controller can be recovered or must be reset or replaced.
• How much of the current cable, readers and lock hardware can be reused.
• How many credentials need to be reissued.
• A subscription platform versus a one-time license.
• After-hours labor for businesses that cannot lose a door during the day.
• How often you want scheduled maintenance.

Because Katy is our home base, a return trip to finish a phase or recheck a door after adjustment is a short drive rather than a scheduling project. For new installs, see our Katy access control panel installation page.
