Questions shoppers ask
Which brand of smart locks has the best warranty?
On paper, Baldwin scores highest, with no full coverage but some parts covered to lifetime. Level Lock covers everything longest, at 2 years.
Is a long warranty on smart locks really that long?
Often not for the whole product. Many longer warranties cover only certain parts after the first year or two, and you usually pay for the labor. The bars above show full and partial coverage separately.
Do I need to register to get the warranty?
None of the 12 brands require registration for their basic coverage. Registering can still get you recall notices. Keep your receipt either way.
Forward the receipt and I-BUY.AI tracks the return window and warranty for you.
