Homes in Cambridge: what pros run into
Much of East Cambridge grew up around factories near the Charles River and Lechmere. Water travels from Stony Brook to Fresh Pond through an underground conduit about 7.7 miles long.
Cambridgeport's triple-deckers went up mostly in the late 1800s as housing for factory workers. Apartment lockouts in older buildings may involve the super or management, so call them first if possible.
Doors swell and shrink with the seasons, which can make deadbolts hard to throw in winter. Inspectional Services issues building, electrical and plumbing and gas permits.
Permits, licenses and your utility
Ask the locksmith for ID, the company name and a written price before any work begins. Renters should check with the landlord before changing or rekeying locks, since many leases require it. If you share a building entrance, mention it, since common doors are usually the landlord's or the association's call.

Which parts of Cambridge can you help with?

My key will not turn. What now?
Try a graphite lubricant. Do not force it, since a broken key is harder to fix. A key that turns stiffly is often a worn key or a dry cylinder, and a fresh copy cut from the code can solve it.
Can I change the locks if I rent?
Check your lease and local rules first. Many landlords require notice and a copy of the new key. If you change them without permission, you may break the lease, and the landlord may be locked out during an emergency.
Can a locksmith match all my locks to one key?
Often, if the locks share a compatible keyway. The locksmith can rekey them to one key or tell you which ones need new cylinders.
Keep receipts and notes from the visit. They help if the same problem comes back.
