"I would like to recognize employee Doug A at SafeStreet/ADT. We’ve had an old security system sitting in our house for over 15 years without service or functionality. He took the time to explain the differences between how the old systems work and how the new systems work. He was patient with us, and we are happy customers."

"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."

"There were many things wrong in my computer (my fault and letting grandchildren on computer) Robert was so helpful, gave me many good instructions to keep everything safe, which I have written down, feel like I have a new computer. He was so excellent and experienced, took his time and was meticulous about what needed to be done. He was a pleasure to work with and I will use this company again! Linda Disy"

Locksmiths FAQs, answered by experts

There are several ways to add security to a sliding glass door. To start, install a rod or deadbolt lock instead of the flip-lock that comes standard with most sliding glass doors. Add a sensor to the door and monitor any activity through your home security system.

Finally, installing shatterproof window film will help keep the structural integrity of the glass if it cracks.

Yes, most pros encourage you to change your locks when you move into a new home. While the previous owner may hand you their keys, you have no way of knowing whether other copies exist elsewhere. Changing your locks as soon as you move in is a great way to ensure that you can enjoy new, fully functioning locks that will work with your unique key or code.

Yes, it’s possible a burglar can get through a deadbolt. Some types of deadbolts are harder for an intruder to get through, though. For example, a single-cylinder lock only requires breaking a window nearby and simply turning it. While other locks, such as a double-cylinder lock, may offer greater protection and make it harder for an intruder, no deadbolt is 100 percent effective.

Yes, locksmiths can design and install master key systems that grant different levels of access to various employees while maintaining overall security.

There are several situations when you should change or replace your locks to ensure your home's security. Key moments include moving into a new house, after a break-in or attempted break-in, or when a roommate or anyone else with a key moves out. It is also wise to change your locks if you lose your keys, especially if they have an address attached or you suspect they were stolen. Finally, if your locks are old, broken, worn out, or have become unreliable, they should be replaced.
