A clearer description of your Watertown door.
Watertown Square, Coolidge Square and the Arsenal Street corridor are distinct local references. Give the actual address and opening so the request is about your property, not just an area name.

Street frontage or shared access?
The city׳’ג‚¬ג„¢s design materials distinguish several commercial and mixed-use areas. At a particular address, the door for customers may not be the entrance to the residences or offices. Say whether the problem affects a shop, tenant suite, shared building door or private unit. Include the person who can authorize changes to that hardware.
A door that stops closing properly
Describe the latch, handle and key separately. If the door needs pushing or lifting, mention it before asking for a replacement lock. A lock repair assessment should consider the installed hardware and how the opening works. Do not assume that changing the key cylinder corrects a door-fit problem.
Changing who can enter
For a home handover or staff key change, list the doors and any shared key arrangement. Rekeying concerns suitable mechanical cylinders. Building cards, keypad codes and account permissions are separate. Coordinate those with the appropriate manager instead of treating a new key as a complete update of every access method.
The last details before you call
Have the full Watertown address, unit or entrance and a short description of what happened. For a car, add the parking location, make, model and year. Ask about availability and the estimate for your request. This nearby-area page is not a separate branch address or a promise that every job is available.
For this situation.
Should I call it a lock change if the door will not catch?
Explain the symptom first. A door that will not latch may need a different assessment from a request to change which key works.
