"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."

"This is the best locksmith I've ever met."

"Front Door locks broken on my home. Had to take off work, no way to secure my home. Home Advisor put me touch with Colonial Lock Service, Inc. the gentleman on the phone tried to help trouble shoot the problem when that failed a locksmith was dispatched. The locksmith called and said I will be there in an hour. This young man showed up on time and said don't worry I hear to make it better. He had such great friendly personality and did a great job. He replaced both of my locks and said "Sir your new locks turn like butter now". Well that made my laugh but he was so right, my locks never worked so good. It appears when the door was replace 15 years ago the locks never really lined up right. The replacement locks were are not your local hardware style, much better quality. I was quoted a price which having never used a locksmith before I thought was high, however the quick response, great service, better then average hardware and most of all the locksmith had a great friendly attitude. The price was right. This young man shook my hand and thanked me. Right when I thought there was no more good customer service in this world, WOW!"

"FrontPoint is fantastic and so easy to work with. They'll patiently walk you through every step of home install. I was able to get smart locks, a visual doorbell, and additional sensors for MUCH less than it would have cost to order the locks alone. Reasonable monthly monitoring fees as well. I would highly recommend! Just be sure to order what you need at the beginning, as the discounts are much better at that time."

"Was able to get an appointment at my convenience, salesman Jeremy was both knowledgeable and personable. Jeremy helped me get the best equipment for my concerns, and together we determined what pieces could wait until I could afford to add more. I was offered a lifetime servicing plan for the equipment at no cost to me or for replacement. The keypad is an awesome piece of equipment (which Larry installed and did an outstanding job with!) and once it was up, I was sort of sad that I didn't just leave it as a "desk top" option that Larry had mentioned so I could move it around the house with me. In hind sight if I had known more about the benefits of leaving it as a desk top option, I probably would have opted for it. But initially I thought it was a "short cut" to install, which it would not have been. By far the coolest thing about 1st Security's service is the fact that they use alarm.com, from which I can arm and disarm my system from my cell phone. No juggling at the door, sprinting to the keypad, etc. I also have a peace of mind that I have never really had with Front Point, Guardian or other security services since I can actually see my alarm activity online and on the app. The system also allows up to 239 individual passwords that you can assign to family members or others you hire to do work at your home. My only disappointment is with signage for the house. I want 2 security signs for my home (relatively higher crime area) but was given one and told he'd get the other one to me only after I offered to pay for it (which honestly, I should not have to do - the more signs in my yard, the better advertisement for your company). Also they "were out of" window clings/stickers, something I want immediately upon install. Larry said they were on order and he would get the stickers and extra sign to me as soon as they were in. I'll update you on that when I get them."
