"What a great guy! We set up an on call situation so he was able to make it out a day earlier than originally thought. He gave me a cash discount. Was done in under 30 minutes. He even explained everything was doing the entire time. Super nice and customer focused. He showed up at exactly the time he said he would too. As soon as I need a lock re-keyed or any lock work done again. I'm calling."

"I called Alarm Protection Group AFTER my office was burglarized. Now I feel SAFE. William is great to work with. He's neat and tidy, prompt, presentable - not a butt-crack type of guy, and he doesn't leave a mess in his wake. He's also knowledgeable about the equipment and only uses high-quality products."

"Walter and Glen at Protect Your Home Group with ADT are the best people to talk to in terms of security alarm. Being a locksmith myself I know how important it is to deal with the right people. I referred a lot of customers to them and so far they are happy with their service. I myself got one for my house. Thank you for a consistent service and great deal."
