We got this lock and was extremely happy with it. It's amazing how easy you can get in your house, even with your hands full. We did have a problem with it just locking and unlocking whenever it chose to. We called and was walked through steps to try and fix it, although nothing worked. They sent us out a new one with no questions asked. The only problem we have, is for the price, I think more free key accesses should be included. We,are very pleased with the lock and the customer service. Thanks for a great product.
