FAQs

Will a smart lock fit my door?

Most smart deadbolts fit standard US doors with a 2-3/8 or 2-3/4 inch backset and a 1-3/8 to 1-3/4 inch door thickness. Check the listing for details.

What happens if a smart lock battery dies?

Most smart locks warn you well before batteries run out, and many include a backup key or external battery contacts.

Can renters install smart locks?

Retrofit smart locks that fit over the existing deadbolt are a good option for renters, but always ask your landlord first.
