Find answers to common questions about our locksmith services, pricing, and coverage throughout DC.
What neighborhoods do you serve in Washington, DC?
We serve all quadrants of Washington, DC, including Capitol Hill, Shaw, Columbia Heights, Navy Yard, Petworth, Dupont Circle, Georgetown, Adams Morgan, Foggy Bottom, and surrounding areas.
Should I rekey my locks or replace them completely?
If your existing lock mechanisms are in sturdy working condition, lock rekeying is a cost-effective choice. Replacement is recommended if locks are damaged, outdated, or lack modern drill resistance.
Can you install smart locks on historic Washington DC doors?
Yes. Our technicians adapt modern electronic smart keypads and deadbolts to fit historic wood doors and custom mortise lock openings without damaging historic door surfaces.
What commercial locksmith hardware do you install?
We install Grade-1 commercial deadbolts, master key systems, panic exit devices, continuous hinges, door closers, and electronic keypad locks compliant with commercial building codes.
Can you replace transponder keys for modern vehicle models?
Yes, we cut and program high-security laser-cut keys, transponder chips, smart fobs, and push-to-start proximity remotes for almost all vehicle makes and models.
How do master key systems work for multi-tenant buildings?
A master key system configures lock cylinders so individual tenant keys open only specific doors, while a master key opens all authorized locks across the facility.
Do you provide upfront pricing before starting work?
Yes. We provide clear, transparent pricing over the phone or upon initial assessment before any installation or service begins.
Are your locksmith technicians licensed and insured in Maryland & DC?
Yes. All Locksmith Guarantee technicians are fully licensed, bonded, and insured professionals trained in physical and digital security standards.
