"WOW. I have a discontinued impossible to find lock on my sliding glass door. I looked everyone, eventually I posted on this lock smith blog a picture begging for help. The owner Terry replied and said that he had one, only one left and gave me his cell phone. I called him and he answered right away. I am in Northern California, he was able to ship it to me which was great. He then continued to text with me as I asked him questions about the door he even threw in a new wheel mount as the tread came off the wheels and he advised I should not run the door like that as it would ruin the track. Thanks so much to Terry, a life saver. I was otherwise looking at having to replace this door for thousands of dollars."
