Key duplication and replacement can be arranged the same visit, including high-security restricted keys that are difficult to copy without authorization.
Moving into a new home or need to revoke access after a rental turnover? Rekeying your locks is often the most affordable solution, since it changes the internal cylinder configuration without requiring new hardware. If you're upgrading instead, our technicians handle multi-point lock installation and repair and can walk you through keyless entry systems for keypad or fingerprint access.

Serving All of Bethesda and Nearby Communities
We serve every Bethesda neighborhood, including Downtown Bethesda, Chevy Chase, Woodmont, and Bradley Hills. Drivers near Chevy Chase and North Bethesda commonly reach out for on-site key programming, while homeowners in Potomac and Kensington more frequently schedule deadbolt upgrades and rekeying after a move.
Coverage extends further to Rockville, Silver Spring, Garrett Park, North Potomac, and Gaithersburg, with additional technicians stationed near Aspen Hill and Olney for shorter dispatch routes across upper Montgomery County.
Commercial Locksmith Solutions for Bethesda Businesses
Local Bethesda businesses require high-security solutions to guard assets and meet safety code compliance. Installing Grade 1 commercial hardware, emergency exit devices, and panic bars provides both reliable security and a clear evacuation route. Commercial lock rekeying prevents former employees or keyholders from gaining entry, establishing clean access boundaries for retail outlets and office buildings.
Access control planning often includes master keying, which lets managers access every office or storage room with one key while staff hold keys restricted to their own workspace. For larger properties, ask about a security consultation to identify weak points before they lead to a break-in or a lockout during business hours.

Frequently Asked Questions
What locksmith services does Locksmith Guarantee offer in Bethesda?
We provide a full range of locksmith services in Bethesda including residential lockouts, lock installation and repair, rekeying, key duplication, car lockouts, transponder key programming, ignition repair, commercial lock systems, smart lock installation, master key systems, and electric strike installation.
What is a business rekey service and when do I need it?
A business rekey service changes the internal pin mechanism of your existing locks so they operate with a new key. You should rekey when keys are lost or stolen, when an employee with key access leaves, or when you take over a new commercial property. It is reliableer and more affordable than full lock replacement and provides professional security control.
Do I need to replace my locks to rekey them?
No. Rekeying only changes the internal pins inside the lock cylinder — the hardware itself stays in place. This makes rekeying significantly more cost-effective than replacing locks while achieving the same security benefit of preventing old keys from working.
Can you rekey multiple locks to work with a single key?
Yes. We can rekey multiple locks across your home or business to operate with one master key for added convenience, while still maintaining the ability to have individual keys for specific doors if needed. This is a common solution for both residential and commercial properties.
Are your locksmiths licensed to work in Bethesda, MD?
Yes. All Locksmith Guarantee technicians operate under Maryland License #507, are fully bonded, and carry commercial liability insurance. We are authorized to perform residential, commercial, and automotive locksmith work throughout Montgomery County and the greater Maryland area.
