Ronald has helped me out too many times to count now with car key issues. He is the best person to go to the DMV and prices a lot fairer than most of the competition in the area or your normal dealership. If you have any key issues, he is the person to go to!

Frequently Asked Questions
Can you help if I am locked out of my house or car?
A1 All Locksmith DMV offers 24/7 mobile lockout help in Gaithersburg and surrounding Montgomery County and Frederick County communities, Maryland. Call 240-701-6448 with your exact location and describe the lock or vehicle. The technician confirms authorization before opening it.
Do I visit a shop?
Mobile service only. We come to your home, business or vehicle; there is no walk-in storefront.
How much will the service cost?
Car and house lockouts start at $89. The exact price is confirmed on the phone before dispatch and again on site before any work begins. A lockout opening is different from replacing a lost car key. Confirm the total estimate and any applicable travel, labor, parts and after-hours charges before dispatch. Approve the final price before work starts.
How soon can a technician arrive?
Call to confirm technician availability, the price estimate and a current arrival time for your exact location.
Can you replace my only car key?
Mobile car key replacement and programming are available for supported vehicles. Have the year, make and model ready. Compatibility, key availability and pricing are confirmed before dispatch; proof of ownership is required.
Can you rekey a lock instead of replacing it?
Rekeying changes the key that operates a compatible working lock. Damaged or incompatible hardware may need replacement. Describe the lock and the number of doors when you call.
Do you speak Spanish?
Yes. Call 240-701-6448 for service in English or Spanish.
