Condo door or neighborhood home?
For a condo, confirm whether the unit door is resident-controlled and whether building staff need to approve work. Exterior appearance rules may affect replacement locks or smart hardware. Have a manager contact available even if the immediate request is only a lockout.
For a house, describe whether the key is lost, the cylinder is difficult, or the door no longer aligns. Rekeying changes key access; it does not straighten a sagging door. We look at those as separate questions and explain the useful next step.
