I upgraded my deadbolt to the Powerbolt2 after replacing my front door handleset which went bad. I just wished i ugraded a long time ago. Having the electronic deadbolt is so convient and easy to own. I never have to worry about forgetting keys. I am also very happy with Kwikset's customer service amd their product warranty. I had issues with my kwikset handle set as i stated earlier, Kwikset took care of my faulty product and replaced it within 2 days. I am definately a customer for life.
