## Services
### Residential Locksmith
- [Rekeying](https://glclocksmithservice.com/residential-locksmith/rekey-locks/) (Rekey Locks) - From $19 per lock. Change the internal pins of your existing lock so old keys no longer work - without replacing the entire hardware. Ideal after moving, losing a key, or after a breakup.
- [House Lockout](https://glclocksmithservice.com/residential-locksmith/lockout-service/) (Residential Lockout Service) - From $45. Locked out of your home? Our licensed locksmiths arrive fast across Garland and DFW to get you back inside without damaging your door or lock.
- [Lock Change](https://glclocksmithservice.com/residential-locksmith/lock-change/) (Lock Change & Installation) - From $65 + hardware. Replace outdated or damaged locks with new, high-security deadbolts and door hardware. We install Schlage, Kwikset, Medeco, and other top brands.
- [Smart Locks](https://glclocksmithservice.com/residential-locksmith/smart-locks/) (Smart Lock Installation) - From $75 + hardware. Upgrade to keypad, fingerprint, or Wi-Fi smart locks. We install and program August, Schlage Encode, Yale, and more - no key needed.
- [Master Key](https://glclocksmithservice.com/residential-locksmith/master-key-systems/) (Master Key Systems) - From $125. One master key opens all your locks; individual keys open only their designated locks. Perfect for landlords, property managers, and multi-unit residences.

### Automotive Locksmith
- [Car Keys](https://glclocksmithservice.com/automotive-locksmith/car-key-replacement/) (Car Key Replacement) - From $85. Lost your car key? We cut and program replacement keys for most makes and models - at your location. No dealership wait, no tow truck needed.
- [Fob Programming](https://glclocksmithservice.com/automotive-locksmith/key-fob-programming/) (Key Fob & Remote Programming) - From $65. Lost or broken key fob? We program replacement fobs and remotes for most vehicles - domestic and import - at a fraction of the dealership price.
- [Ignition](https://glclocksmithservice.com/automotive-locksmith/ignition-repair/) (Ignition Repair & Replacement) - From $95. Key won't turn, ignition is stuck, or your car won't start? We diagnose and repair or replace ignition cylinders on-site without towing your vehicle.
- [Transponder Keys](https://glclocksmithservice.com/automotive-locksmith/transponder-keys/) (Transponder Key Programming) - From $95. Transponder keys have a microchip that communicates with your car's immobilizer. We cut and program transponder keys for most vehicles at your location.

### Commercial Locksmith
- [Access Control](https://glclocksmithservice.com/commercial-locksmith/access-control/) (Access Control Systems) - Custom quote. Keypad, card reader, and biometric access control installation for offices, warehouses, and multi-tenant buildings across DFW.
- [High-Security](https://glclocksmithservice.com/commercial-locksmith/high-security-locks/) (High-Security Lock Installation) - From $150 + hardware. Medeco, Mul-T-Lock, and other UL 437-rated high-security locks for businesses that need maximum pick, drill, and bump resistance.
- [Door Closers](https://glclocksmithservice.com/commercial-locksmith/door-closer-repair/) (Door Closer Repair & Installation) - From $85 + hardware. Door closer repair corrects a commercial door that slams, closes too slowly, drags, or fails to latch. Leaking hydraulic oil, a bent arm, stripped mounting holes, or a closer that will not hold its speed setting usually points to replacement, while sound hardware may only need alignment and valve adjustment. On site, GLC inspects the closer, hinges, frame, door weight, and latch, then quotes repair or replacement before work begins and tests the full closing cycle.
- [Keypad Locks](https://glclocksmithservice.com/commercial-locksmith/keypad-locks/) (Keypad Lock Installation) - From $125 + hardware. Keypad lock installation gives a business code-based entry without issuing a physical key to every user. Door thickness, existing prep, handing, frame alignment, fire rating, and any exit device determine which lock fits; a sagging door or binding latch must be corrected so an accepted code actually retracts the hardware. On site, GLC checks the opening, explains standalone or connected options, quotes the job before work begins, installs and programs the lock, and tests entry, free egress, and the key override.
- [Lock Replacement](https://glclocksmithservice.com/commercial-locksmith/commercial-lock-replacement/) (Commercial Lock Replacement) - From $95 + hardware. Commercial lock replacement removes worn, damaged, or unsuitable hardware and installs a lock matched to the door and its use. A rough-turning cylinder, loose spindle, cracked case, recurring latch failure, or incompatible storefront hardware can justify replacement, while a sound lock body may only need rekeying or alignment. On site, GLC checks the door, frame, latch, keyway, traffic, and egress function, then quotes the work before it begins and tests every key and locking function.
- [Commercial Master Key](https://glclocksmithservice.com/commercial-locksmith/commercial-master-key-systems/) (Commercial Master Key Systems) - From $200. A commercial master key system lets authorized managers open multiple selected doors while each employee or tenant key opens only its assigned doors. GLC maps access roles, door groups, cylinders, and keyways before pinning the system; worn cylinders or mixed, incompatible keyways may need replacement instead of rekeying. On site, we inventory the openings, confirm who needs each access level, quote the project before work begins, and test every issued key against the plan.
- [Alarm Lock Trilogy](https://glclocksmithservice.com/commercial-locksmith/alarm-lock-trilogy/) (Alarm Lock Trilogy Locks) - From $150 + hardware. Alarm Lock Trilogy installation mounts, hands, programs, and tests the correct Trilogy lock for a commercial door. A unit that accepts a code but does not retract the latch may have incorrect handing, spindle engagement, or door alignment rather than a programming fault, while damaged electronics or a worn chassis can make replacement the better choice. On site, GLC verifies the exact model and door prep, quotes the work before it begins, programs authorized access, and tests the lever, latch, free egress, and key override.
- [Panic Bars](https://glclocksmithservice.com/commercial-locksmith/panic-bar-repair/) (Panic Bar Repair & Installation) - From $95. Panic bar repair restores an exit door that sticks, will not retract, or fails to latch after closing. Common causes include a failed dogging mechanism that leaves the bar retracted, a loose chassis, worn latch parts, a shifted strike, or door and frame misalignment; repair versus replacement depends on the device body, available parts, and condition of the opening. Panic hardware is life-safety equipment, so GLC quotes the work on site before it begins and tests free egress, relatching, accessible operation, and fire-door function where applicable.
- [Exit Devices](https://glclocksmithservice.com/commercial-locksmith/exit-devices/) (Exit Device Installation) - From $150 + hardware. Exit device repair restores a commercial push bar that sticks, will not fully retract, or fails to secure the door after use. A worn return mechanism, binding latch, loose chassis, shifted strike, or rod adjustment can cause the failure; on a concealed vertical-rod device, the top latch may stop engaging even though the bar still moves. Because exit devices are life-safety hardware, GLC checks the full door and frame, quotes repair or replacement before work begins, and verifies free egress, relatching, accessible operation, and fire-door function where applicable.
