Replacing the Key Ring: Low-Voltage Access Control in Richmond, TX

What stands behind Richmond’s doors, from downtown to Harvest Green

Richmond is the Fort Bend County seat, and its buildings span more than a century. The migration from keys looks different in each part of town:

• The historic downtown and county government blocks. Older brick buildings with wood doors in wood frames, transoms, tall ceilings and few hidden paths for cable. Many house law firms, title companies and other offices that work with the courts, where records rooms matter.
• The US-90A, FM 762 and FM 359 corridors. Strip centers, clinics, auto and trade businesses in metal buildings: aluminum storefront entries in front, hollow metal doors in back.
• Church and school campuses. Several buildings, many exterior doors, and a long list of volunteers and staff who each need different hours.
• Established neighborhoods such as Pecan Grove. Homeowners who want a keypad on a side gate, a workshop or the garage entry rather than a full system.
• Newer master-planned communities such as Harvest Green, Veranda, Aliana and Long Meadow Farms, where the association runs pool gates, fitness rooms and clubhouse doors on a schedule.

The Grand Parkway runs directly from our Katy base down to Richmond, so the city sits comfortably inside our regular service area. Call to set up an on-site estimate for your address.

What a key can never tell you, and a credential can

A metal key has no memory. It cannot report who used it, it cannot expire, and it can be copied at a hardware store despite a “do not duplicate” stamp. When one goes missing, the honest fix is rekeying every lock it opened and reissuing keys to everyone else.

A card, fob, phone credential or PIN reverses each of those weaknesses. You can:

• disable one person’s credential in seconds without touching anyone else’s;
• limit a credential to certain doors and hours, such as the youth wing on Wednesday evenings only;
• pull a report of every entry at a given door on a given night;
• unlock the front door on a schedule instead of relying on whoever arrives first.

It is worth being plain about the limits, too. A credential system does not stop someone from holding the door for a stranger. It needs a named person to administer it, or the database drifts until nobody knows who still has access. And it does not remove keys entirely, because every electrified lock still needs a mechanical override for emergencies.

Surveying each opening before choosing any hardware

We do not recommend a single lock for a whole building. Every opening gets recorded on its own line:

1. Door material: hollow metal, solid wood, aluminum storefront or glass.
2. Frame: steel, wood or aluminum, and whether a steel frame in a masonry wall is grout-filled, which makes cutting a strike pocket and routing cable much slower.
3. Existing lock: cylindrical lever, mortise lock, exit device, or a storefront deadlock with a hook bolt.
4. Stile width on aluminum doors, since narrow stiles leave room for only certain hardware.
5. A fire label on the door or frame, which limits what may be cut into it.
6. Hinges and closer: butt hinges, continuous hinge or pivots, and whether the closer actually pulls the door shut and latched.
7. Alignment: a sagging door whose latch barely catches today will not engage an electric strike reliably.
8. Pathway and power: accessible ceiling, attic or crawl space, masonry to drill, and where the lock power supply can live.

That list is what lets us keep existing doors and most existing hardware, which is usually the largest saving in a retrofit.

Least-disruptive options for the doors Richmond buildings already have

A phased plan: the doors people use daily, then the rooms that matter

Phase 1: the daily entrances

Start with the main entry and the staff or volunteer entrance, the doors that account for most key use. Install a controller with spare reader ports, and while ceilings are open, pull cable to the doors planned for later so phase 2 does not repeat the labor.

Phase 2: sensitive rooms

Records rooms, the network closet, medication storage, a counting room or a sound booth: interior doors where the audit trail is worth more than the convenience.

Phase 3: everything else, or nothing

Some doors never need a reader. Those can stay on keys, ideally on a restricted keyway whose blanks are not sold at hardware stores.

The step most retrofits skip

After the switch, every old key still opens every mechanical override cylinder unless those cylinders are rekeyed. We rekey the overrides to a small set of keys held by two or three named people, so the credential system becomes the real control rather than a second way in.

Enrollment follows the organization’s real groups. A church might set up worship team, youth staff, office, custodial and facility committee, each with hours that match what they actually do.

Where a Richmond owner can go it alone, and where a low-voltage installer belongs

Reasonable to do yourself: a battery-powered keypad or Wi-Fi smart lock on a house door, a detached workshop or a single small-office door, where nobody needs central reports and the lock simply replaces a deadbolt.

Call a low-voltage contractor when:

• more than a couple of doors need to be managed from one place, with schedules and an audit trail;
• the door is on a required exit path in a commercial or assembly building;
• the lock must release with the fire alarm;
• a magnetic lock, exit device or storefront hardware is involved;
• cable has to be fished through masonry, plaster or a finished ceiling;
• a gate or a second building has to join the system.

How EVOTECH runs a Richmond keys-to-cards project

1. Collect the current key list, as far as anyone knows it, and the groups that need access.
2. Survey every opening using the checklist above.
3. Mark which doors go in phase 1, which wait, and which stay on keys.
4. Choose the controller and software: locally hosted or cloud-managed, sized for the final phase.
5. Send an itemized quote by door and by phase.
6. Install cable, the power supply, controller, readers and door hardware; adjust doors that do not latch reliably.
7. Test each door for fail-safe or fail-secure behavior with power removed, and verify fire alarm release where it applies.
8. Rekey the override cylinders and document who holds those keys.
9. Enroll users by group, then coach whoever will run the system day to day and leave written notes on every opening.

What sets the price, and the retrofit errors that come back

Price drivers: how many doors are in each phase; whether frames are steel, wood or grout-filled; whether existing locks can stay; pathway difficulty in older masonry buildings; exit devices or maglocks with their egress components; the number of users and credential type; hosted software subscriptions versus a one-time license; fire alarm coordination; and work outside business or service hours.

Errors that bring an installer back:

• Override cylinders left on the old keys, so every lost key still works.
• A keyed storefront deadbolt still thrown at night, defeating the card reader each morning.
• An electric strike installed on a sagging door, so it releases but the latch binds.
• A controller with no spare capacity, forcing a second panel in phase 2.
• Doors without position switches, so a propped door never raises an alert.
• Volunteers sharing one card, which erases the audit trail the project was bought for.
• Nobody named as administrator after the installer leaves.
