Lockouts
Car, home and business lockouts. We open the door, check the ID the law requires, and can rekey or cut a spare while we are there.

Lockouts, installs, repairs and master keys
Lock Installation
Deadbolts, handle sets, smart locks and commercial hardware, fitted so the door latches cleanly and the strike holds.
Lock Repair
Locks that stick, need jiggling or will not latch. We find the cause first and tell you whether repair or replacement makes sense.
Master Key Systems
One key for managers, limited keys for everyone else, and a record of who holds what. Designed with you and keyed on site.

How a call works
You call (240) 763-3127 and tell us what happened and where you are. We ask a few questions about the lock or the vehicle so the technician brings the right parts, and you hear the estimate on the call. When the technician arrives, they check the ID the law requires for the job, confirm the estimate, then start work.
What we check before opening anything
For a home lockout we check a photo ID and proof that you live at the address. For a car we check ID and proof of ownership. For a business we confirm you are authorized for the property. It protects you as much as anyone.
Car keys without the dealer
Our technicians carry the tools to cut and program most car keys where the car is parked. Some newer models need dealer authorization, and we tell you on the call if yours does.
Paying
We take cash, card, PayPal, Venmo, Cash App and Zelle, and payment plans are available. Locks and keys we supply carry a 30-day warranty; if you supply the hardware, it covers our labor. Lockouts are not covered by the warranty.
