Start with the door, not a diagnosis
A missing key, a key that turns without releasing the latch and a door that will not move are different problems. Tell us which one happened, whether another entrance is available and whether a key is still inside the lock. If the door belongs to a shared building, identify whether you need the outside entrance or your individual unit opened.
The right entrance matters in DC
Include NW, NE, SW or SE with a DC street address. Add the unit, building entrance and a nearby cross street. For an apartment, coordinate with the concierge or property manager if possible. For a car, give the garage name, floor and vehicle position; the street address alone may lead to a different entrance.
What to establish before work begins
Ask about the estimated arrival window, call-out charge, expected labor and any possible additional work. Opening a door does not automatically require a new lock. The condition of the hardware and the available entry options should be assessed before a replacement is proposed. Confirm the scope and price before authorizing a change.
After access is restored
Check that the door closes and locks normally. If keys were lost rather than left inside, discuss whether rekeying is appropriate. Keep the invoice and any new keys together until you have tested each affected lock. A recurring sticking latch deserves a repair assessment instead of repeated lockout visits.
