Opening the shop or securing it afterward
Moody Street and Main Street have a different access setting from a private driveway or residential side entrance. For a business door, explain whether the key, latch or door-closing action is causing the trouble. Identify the person who can approve the work.
If the business occupies a leased unit, the property manager may control the lock system or need to be involved. Changing keys for one storefront should not accidentally change access to a shared building area.
Unit door or shared entrance?
At a multiunit home, including the South Side’s residential streets, begin by identifying the specific door. The lock to your apartment and the entrance used by other residents may require different permissions.
For a move-in, list the locks you are authorized to change and whether you have working keys. Rekeying may preserve suitable existing hardware. If a key sticks only when the door is closed, mention that so door fit can be assessed alongside the cylinder.

Before you call
- Private unit, shared entry or business door
- Landlord or manager approval where needed
- What the lock does with the door open and closed
Make the estimate specific to the job
Give the actual Waltham address and any access instructions rather than relying on a neighborhood name. Ask about current availability, visit charges, labor and expected parts. If the condition found at the door changes the work needed, discuss the revised scope before approving it.
Street access can vary. Describe current parking or entrance restrictions when you call; this page does not promise a particular route or arrival time.
A useful question
Should I replace a lock before moving into a Waltham rental?
Check with the landlord first. A key-access change may be possible through rekeying, while damaged or unsuitable hardware may need replacement. The property’s existing key system and your permission to change it matter.
