"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."

"Really well; the company was able to wire everything as originally planned. The installation was completed in 2 days; we tested the system for 3 days, and we have had no trouble with it at all. The installation involved very little mess or inconvenience and we are delighted with the results. We would recommend L & R to anyone looking for a sophisticated security system that operates in an astonishingly simple way.

"Jim Lockhart is the best of the best. From the time we were planning our project right through completion, he was the model of precision and professionalism. While Jim owns the business, he also worked on site each and every day. Our project together included a 2nd floor master suite addition, additional bathroom remodel, new roof, siding, windows, and HVAC! Jim was always on time and showed up when he said he was. Once our project started he was there every day consistently and worked incredibly hard each day. He worked with high quality sub-contractors when necessary (roof, electrical, and plumbing) and held them to highest standard and was on site while they worked. While construction was occuring, Jim was careful to keep our house as clean as possible and took extra care to ensure my children were comfortable and safe and their home. Jim even took the time say good morning to our dog each day in an effort to make our whole family comfortable! He cleaned each and every day. He was a master communicator and walked us through each step from start to finish. Jim worked on our home for almost 6 months and he took every detail seriously every day. I would highly recommend Jim for any scale job! You would be hard pressed to find a more skilled or professional contractor!"

"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."

Locksmiths questions, answered by experts

Proper door lock maintenance includes keeping the locking mechanism clean and clear of dirt, dust, and grime buildup, lubricating the lock annually, inspecting and tightening the lock regularly, and treating the door with care. If your maintenance reveals problems, it may be time to replace the lock or have a professional inspect it.

Most door knobs can be removed with a Phillips or flathead screwdriver. If you don’t have either of those available, a paper clip or small pin can sometimes work, but the extra effort may not be worth a quick trip to the hardware store.

Yes, you should change the locks as soon as you can after completing the purchase of a house. This is a matter of privacy and security, as you have no idea how many copies of the keys the previous owner made. You can change the locks yourself or hire a pro to replace or rekey the lock, which costs $50 to $100.

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.

Using a combination of tools (often store-bought plumbing tools) and brute force, a burglar can easily snap the lock on a door. Snapping a lock aims to gain access to the cylinder inside, which holds the locking mechanism. Once the thief snaps the lock, they can pick the cylinder open and walk right in.
