""This is a very belated review, last year our house was broken into and our front door and lock were damaged. We had an emergency locksmith fix the lock the same day, but he did a pretty poor job. These nice folks came over to quote for a replacement door and saw my lock was not fit for purpose and without me even asking for their help offered to fix it for me. They did it in a jiffy, on the spot, and did not even ask me to compensate for it. It took such a weight off my mind because I was so worried about getting locked out of my house one evening due to the lock being banged up. We ultimately went with someone else for our door (Banham, extremely overpriced but after what we went through, we wanted to be ultra-cautious) but I was so impressed with Under Lock And Key's service and if we had not been broken into twice in one year we would have gone with them rather than Banham. They were very accommodating to our requirements and custom needs and reasonably priced for the quality and service. Thank you so much to the 2 men that came over and fixed our lock a year ago, it really made such a difference to us."
