We originally had issues with the KEVO lock we purchased at Lowes. It would kill a set of batteries in a matter of weeks, when the box said they should last for a year.
I contacted KEVO customer service and they sent me out a new lock to replace the faulty one. This one has operated exactly as advertised. Weve had it on the house for nearly a year and were on the same set of Duracell batteries I installed when I put it in service.
