I want to go keyless in my new back door. I had a Weiser keyless lock in the old door and have a Schlage in my front door. Both are OK to use although we use the front door very little so I can't really attest to the Schlage's durability. The Weiser has conked out quite a bit. We've changed batters many times and finally got a new circuit board. It's not worth transferring it to the new door. I'm hoping there's someone who has a fairly new keyless lock who could give a review. Thanks
