Rampart Welding repairs DoorKing gate operators and telephone-entry systems across Houston — slide and swing operators, barrier arms, and the 1812, 1802, and 1835 entry systems. We program, repair boards, and convert dead landlines to cellular. Call (713) 816-5880.
DoorKing is the standard on Houston HOA and apartment gates — both the operators and the telephone-entry call boxes. When residents can't get in or the gate won't run, we service the whole DoorKing system, entry and operator together.

If a resident's call connects but the gate doesn't open, the fault is usually the relay, the wiring between the entry panel and the operator, or the operator itself — not the call box. If calls don't connect at all, it's typically a dead landline that needs cellular conversion. We test both halves.
DoorKing entry problems split into two categories: the call doesn't connect (a phone-line issue, increasingly a retired landline) or the call connects but the gate doesn't move (a relay, wiring, or operator issue). We diagnose which and fix the actual break, since they're entirely different repairs.

Free estimates for structural repairs and new installations. Flat diagnostic fee for opener and electronic troubleshooting.
DoorKing HOA and commercial work falls under our $250 diagnostic, credited toward the repair if approved. Landline-to-cellular conversion is quoted in writing after we confirm the line status. 30-day billing available for management companies.

We service DoorKing slide and swing operators, barrier arms, and the 1812, 1802, and 1835 telephone-entry systems common on Houston HOA and apartment gates — including programming, board repair, and landline-to-cellular conversion.
If a resident's call connects but the gate doesn't open, the fault is usually the relay, the wiring between the entry panel and the operator, or the operator itself — not the call box. If calls don't connect at all, it's typically a dead landline that needs cellular conversion. We test both halves.
Yes. Carriers are retiring the copper landlines many DoorKing entry systems relied on. We convert these units to cellular so the entry system keeps working without a landline.
Yes. We program and reprogram entry codes, resident directories, and access settings on DoorKing systems, and can train your manager on routine changes.
