Can you rekey a whole triple-decker?

Yes, we do this weekly for Somerville landlords. Can rekey all three units in one visit. Keyed alike or differently based on your preference.

Do you work with property managers?

Yes, several Somerville property management companies use us for their entire portfolio. Volume pricing available.

What about smart locks for student housing?

Very popular request. We install smart locks in Tufts-area housing so roommates can have temporary codes instead of physical keys.

Should I rekey my locks or replace them entirely?

Rekeying is cheaper and works great if your locks are in good condition—just changes the internal pins so old keys don't work. Replace locks if they're worn out, damaged, or you want to upgrade security. We'll inspect your locks and recommend the most cost-effective option.

Can you work on old locks in historic Somerville buildings?

Yes. Many Somerville homes have vintage locks from the early 1900s. We can repair, rekey, or source parts for antique lock mechanisms. If repair isn't possible, we'll recommend period-appropriate replacement hardware.

Can you come out the same day?

Usually yes. For emergency lockouts, we respond as quickly as possible. For non-emergency services (rekeying, installations), we often have same-day or next-day availability.
