Is Locksmith Guarantee a licensed Maryland locksmith?

Yes. Locksmith Guarantee holds Maryland Locksmith License #507, maintains BBB A+ Accreditation, and dispatches mobile workshops from 5442 Stream Bank Ln, Greenbelt, MD 20770.

What proof of authorization do I need for a home, business, or car lockout?

Please have government-issued photo ID plus documentation connecting you to the property or vehicle—such as a lease, deed, utility record, manager authorization, or vehicle registration matching the VIN.

What if a child, elderly relative, or pet is locked inside a car or room?

If anyone's health or safety is at professional risk, call 911 as scheduled rather than waiting for standard locksmith dispatch.

Should I rekey my locks or replace the whole lockset after moving in?

If the existing cylinders rotate smoothly and the exterior hardware is sturdy, rekeying resets internal pins to new keys at lower cost while keeping your trim. Replace hardware when latches bind, spindles sag, or you want higher security or keypad access.

Can all exterior doors on my house be set to use one single key?

Yes, whenever every cylinder shares a compatible keyway profile (for example, all Schlage C or all Kwikset KW1). Mixed keyways require swapping incompatible cylinders first.

Why does my deadbolt work fine with the door open, yet stick when closed?

That points to door-to-frame alignment—hinge sag, swollen wood, or tight weatherstripping pushing the bolt against the strike plate—not a bad key. Adjusting and deepening the strike box prevents snapped keys and burnt-out keypad motors.

Can you fix a Kwikset SmartKey lock that stopped working during a DIY reset?

Often yes. Pulling a key partway out during a SmartKey reset desynchronizes internal wafer carriages; we can reset the core on a dedicated cradle or swap in a compatible replacement cylinder.

How do I open a keyless touchscreen smart lock when the batteries die?

Check whether your model has a hidden mechanical override cylinder or two 9V emergency jump terminals underneath the keypad; holding a fresh 9V alkaline battery firmly to the contacts powers the screen temporarily so you can enter your PIN.

Can you add a standard deadbolt to a commercial fire-exit door?

Designated commercial exit and fire-rated doors must preserve single-motion interior egress and fire-label integrity; instead of illegal slide bolts or secondary deadbolts, use code-compliant panic bars, alarmed exit hardware, or Grade 1 storeroom/classroom levers.

What is the difference between keyed-alike locks and a commercial master-key system?

Keyed-alike locks all open with one identical key, whereas a tiered master-key system gives individual keys to separate suites or offices while letting an authorized manager's master key open the group.

Can your mobile van make a replacement car key if I lost every key?

For many supported domestic, Asian, and select European vehicles, yes—we originate the mechanical or laser blade and pair compatible transponder/smart fobs at your parked vehicle without towing to a dealership.

Should I buy an inexpensive replacement car key fob online first?

Confirm compatibility before ordering: look-alike fobs frequently carry the wrong MHz frequency, omit the transponder chip, or arrive permanently locked to another car's VIN.

Does erasing a lost electronic car fob stop the missing metal blade from opening the door?

No. OBD key deprogramming blocks engine start and remote buttons for the missing fob, while mechanical door cylinders must be rekeyed or replaced if physical cabin entry is a concern.

Can you open an electronic or mechanical safe without ruining it?

Opening methods depend on the safe's UL security rating, lock model, and whether an internal relocker has fired. Send a photo of the safe door and keypad/dial first so we can check non-destructive vs. precision repair options.

Do you have local walk-in storefronts in every Maryland town listed on your site?

No—5442 Stream Bank Ln, Greenbelt, MD 20770 is our dispatch base, and all city/county pages describe mobile on-site locksmith service.

How are service prices confirmed?

After checking your details by phone and inspecting the lock, door, or vehicle on-site, our technician explains the recommended work and confirms the total price before starting.
