I have worked with this company for years. As a REALTOR, I need competent, trustworthy and reliable contractors to call and to refer my clients to. I also need someone who will show up looking clean and presentable. John is all of this and much more. He is great with rekeys, fixing locks, lockouts, etc. If he doesn't handle it, he knows a reputable contractor who can. I cannot recommend Collin's Locksmith enough!
