"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."

"The garage door sensor isn't working right and they are sending a different model. We've needed to call them several times to get this sorted, but they are good on the phone.
They nickel and dime on the equipment, wanting to charge us 7$ to ship a keyring and it took 7 days to arrive. And then when a sensor was failing they wanted to send a new one but with same slow shipping which would have left our house insecure for a week. I had to moan about it til they agreed to send it faster, but I feel like, "duh, I'm paying to have security when I want it, not just at times when you can get your shipping and your defective gear working.'
So sure I like them, but it leaves a bad taste that I had to suggest to them they should support their products and service. I'd have preferred it if they just had a policy of providing high evel service right out of the gate.
The gear is GE sensors and the phone app seems like a licensed deal, works well. Now we know we can probably do it all cheaper by just buying sensors and contracting for monitoring service seperately, but this is our first experience with home security and I appreciate the level of service. WHen our contract is up, I'll shop around for monitoring but this was a good way to get into it.
Costing us about 49/mo. and we like having the piece of mind.

"We learned on a Friday afternoon that my husband needed a criminal background check in order to participate in an international program - that he was scheduled to fly out for on Sunday morning! We found many online providers that offered an "instant background check" service, but were hesitant to give his SS# to just anyone, so we came to Angie's List to see if any trusted providers were listed here. Upon finding CSI Secure Solutions, I called them directly, and Chris himself (the owner) answered the phone. He personally committed to get it done, and he worked with me directly to get exactly what I needed within the time frame required. He made a stressful situation very seamless and simple, and I recommend him extremely highly!"

Locksmiths FAQs, answered by experts

The good news is that, yes, you can change locks yourself. Many people find it’s an easy DIY project that requires few tools and not much expense (depending on which lock you’re installing). If you have trouble with any part of an installation, you can always call a locksmith to help finish installing them.

Newer, electric-powered door locks generally have a life span of five years or less. That’s thanks, in large part, to a phenomenon called planned obsolescence, in which products are programmed to need replacing after a certain amount of time. That’s also why older, manual, push-key locksets can last up to 30 years with regular cleanings and maintenance. When it does come time for a new set-up, know that the cost to change locks ranges from $130 to $500 on average.

Yes, but adding a deadbolt to some door materials, like steel, may make installation a little bit trickier. For these materials, you will want to hire a locksmith to do the work for you, but be aware that they may charge an additional fee of $25 to $50 or more.

Changing door locks is a task that most homeowners can accomplish on their own. Standard door knobs are quite straightforward, and even more advanced locks, like electronic or smart locks, generally come with instructions. That said, the process can be time-consuming, especially if you plan to replace multiple locks around the house. It’s also a task that you want to complete correctly, considering that it affects the security of your house. That’s why hiring a pro is often best when changing your door locks.

Yes. Most deadbolts purchased from a home improvement store include a step-by-step installation template that is easy to follow, even for novice DIYers. One of the most important steps for successful deadbolt installation is having the proper tools to start with and carefully measuring prior to any attempts at installation.
