40% Off Teeho Keyless Deadbolt

This Teeho Keyless Deadbolt drops from $59.99 to $33.99 at Amazon, saving you 40% off the regular price. This is an affordable alternative to the name-brand ones that are sold for $60-$80. It comes in three colors (Satin Nickel, Matte Black, and Oil-Rubbed Bronze), can be used with up to 20 different key codes, and has an auto-locking safety feature. It runs on four AA batteries, includes a two-year warranty, and has lifetime customer service. Shipping is free with Prime or when you spend $35. Otherwise, it adds $6.99. Editor's note: I've been researching smart locks, and this one kept popping up on "best of" lists. It's no-frills, but reviewers love it!
