"I contacted Colonial on 10/10/13 and the next morning Steve called and came right away in the heavy downpours. Steve provided Superior service and identified our needs immediately to secure our front door especially with having two small kids.
Steve is great example of professional and courtesy service and represents Colonial Locksmith very well. Colonial Locksmith should be very proud having someone like Steve represent their company in the community.
I would highly recommend anyone in the area that needs a locksmith that will do the job fast and right the first time with a backed guarantee, you can't go wrong.
Many thanks

"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."
