Doors, locks and keys at home

Most of our residential work falls into three situations: someone is standing outside a door that will not open, someone just moved in and does not trust the existing keys, or a lock is worn out and needs replacing.

Moving into a place in San Francisco

You do not know how many keys to that door exist. Previous tenants, a cleaner, a contractor, a building manager. Rekeying the cylinder ends that question in one visit.

✓
Rekey or replace. We will tell you which one the door actually needs.
✓
Match the keys. One key for the front door and the mailbox where the hardware allows it.
✓
Landlords and property managers. Turnovers between tenants are routine work for us.

Questions people ask

Should I rekey or change the locks?

If the lock works well and you only need the old keys to stop working, rekey. If the hardware is worn, damaged or too weak for the door, change it. The difference, explained.

Can all my doors work with one key?

Often, yes. Locks of the same type can be rekeyed to match, so one key opens the front door and the back door.

Do you work on older San Francisco doors?

Yes. A lot of the city's flats still have their original mortise locks, and we repair and rekey them as well as installing new hardware.
