Our front door deadbolt stopped turning, it was jamming for some time now and this morning it got completely stuck leaving us locked out, Kyle was the locksmith who came on behalf of San Francisco Door & Lock and he handled the situation quickly and very professionally, he quickly removed the old lock, installed an upgraded one and rekeyed it so we could use our existing key, Kyle was quick and very efficient, his price was totally reasonable and we are very happy with the result.
