I arrived at work one morning to discover that my shop had been broken into. I called Chi-Town Guard straight away and 15 minutes later somebody was at my door step! The technician filled me in on the different types of security locks available, and helped me decide which kinds of security locks were best for me. The locksmith guy from Chi-Town Guard was really professional and helpful. He even gave me a good price on the security locks because I brought more than one. I would definitely recommend Chi-Town Guard.
