What types of access control systems do you install?+
We install keypad (PIN), key fob/card (RFID), biometric (fingerprint), and smartphone-based access control systems. We work with brands including Schlage, Kisi, LiftMaster, and more.
Do you service multi-location businesses?+
Yes. GLC Locksmith serves businesses across 24 DFW cities. For multi-location access control, we can deploy unified systems manageable from a single dashboard.
How much does access control installation cost?+
A single standalone door - a keypad or card reader with an electric strike - typically runs $300-$1,500 installed. Networked multi-door systems with badge management software run $1,000-$2,500 per door depending on reader type and door hardware. We quote the full scope after a free on-site assessment, and a standalone keypad lock is often a lower-cost alternative for a single door.
What makes a lock 'high-security'?+
High-security locks meet UL 437 standards - they resist picking, drilling, bumping, and key duplication. Brands like Medeco and Mul-T-Lock use patented key profiles that can't be duplicated without authorization.
Are high-security locks worth it for a small business?+
Yes, especially for exterior doors, server rooms, or areas with sensitive inventory. The cost difference ($150-$300 per lock vs $30-$60 for standard) is small compared to a single break-in.
Can high-security locks be keyed alike?+
In many cases, yes. If the lock family and keyway allow it, we can key multiple doors alike or plan a master-key setup so the right people get the right level of access.
How do I know if my door closer needs repair or replacement?+
If the door only needs speed or latch adjustment, a repair is usually enough. If the arm is bent, the body leaks oil, or the closer will not hold calibration, replacement is the better fix.
How much does door closer service cost?+
A simple adjustment is usually $85. Full replacement typically runs $150-$450 depending on the closer grade, arm style, and door weight. Hardware is extra when the closer must be matched to the existing door.
Do door closers have ADA requirements?+
Yes. Accessible doors should close at about 5 lb of force or less and take about 5 seconds to move from 90 degrees to 12 degrees. We set the closer so the door latches without slamming and stays code compliant.
Can you install a keypad lock without running new wires?+
Yes. Many commercial keypad locks are battery powered and retrofit to the existing door prep, so we can install them without new wiring in a standard one-door setup.
How many user codes can a keypad lock store?+
A mechanical keypad lock usually has a single code. Electronic models can store roughly 100-2,000 user codes, including systems like Schlage CO and Alarm Lock Trilogy, depending on the model.
How much does keypad lock installation cost?+
Installation starts at $125, then hardware typically adds $200-$900 depending on whether you choose a basic mechanical lock or a networkable electronic model with audit trail features.
What lock grades do you recommend for commercial doors?+
We usually recommend ANSI Grade 1 or Grade 2 hardware for exterior and high-traffic doors. Grade 3 is lighter duty and better suited to low-traffic interior doors.
Should I rekey or replace a commercial lock?+
Rekey if the lock body is still solid and you only need a new key pattern. Replace if the lock is worn, damaged, mismatched to the door, or you want a better grade of hardware.
Can you replace locks on storefront aluminum-glass doors?+
Yes. We can replace mortise and storefront hardware on aluminum-glass doors, including cylinders, levers, and exit trim when the existing setup allows it.
How does a commercial master key system work?+
We build a key hierarchy with change keys for individual doors, master keys for grouped access, and higher levels when a property needs multiple access tiers. That lets one key open selected doors without giving blanket access to every lock.
How is this different from a residential master key system?+
Commercial systems are usually larger, use more restricted keyways, and are planned around staff roles, storage areas, and tenant access. A residential landlord system is usually smaller and simpler.
How much does a commercial master key system cost?+
A small office system can start around $200. Multi-level systems for larger properties typically run $500-$2,500 depending on the number of locks, the keyway, and the level of access control required.
What is an Alarm Lock Trilogy lock?+
Alarm Lock Trilogy covers models like the DL2700 and DL3000. They are standalone keypad locks with code capacity ranging from about 100 to 2,000 users, and some PDL models can tie into a networked system.
Can you reprogram an Alarm Lock Trilogy that is already installed?+
Yes. If the lock is already on the door, we can usually reprogram codes, schedules, and user access on-site without replacing the unit.
How long do the batteries last and is there a key override?+
Battery life is often around a year or more depending on use. Trilogy locks also keep a physical key override, so the door can still be opened if batteries run low or the electronics need service.
When are panic bars required in Texas?+
Panic hardware is commonly required on assembly and educational occupancies with 50 or more occupants. The exact code trigger depends on occupancy type, occupant load, and door function.
Should I repair or replace a panic bar?+
If the bar is loose, the latch needs adjustment, or the rod just needs tuning, repair is usually enough. If the device is bent, missing parts, or past repair, replacement is the better value and usually starts higher than a basic adjustment.
Can a panic bar still lock from the outside?+
Yes. Exterior control can come from keyed trim, a keypad, or access control hardware, while the inside bar always allows free egress. Alarmed panic hardware is also an option when you want an audible alert on unauthorized use.
How do you choose between rim, vertical rod, and mortise exit devices?+
Rim devices are common on single doors, vertical rod devices fit double doors and tall openings, and mortise devices are used when the door and frame are already prepped for that hardware style.
What is the difference between fire-rated and panic-rated exit devices?+
Fire-rated devices are built for rated openings and should not use mechanical dogging on a fire door. Panic-rated devices are for egress safety, and we match the device to the door rating before installing it.
Can exit devices work with access control?+
Yes. We can pair exit devices with electrified trim or access control release so entry is controlled from outside while the inside bar always stays free for egress.
