"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."

"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!"

"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

Any type of dead bolt lock provides the highest level of safety for a single device. However, it’s also important to determine a lock's grade. Locks can come in either Grade 1, Grade 2, or Grade 3, which indicates how durable it is and if it’s constructed solidly. Safety experts recommend choosing locks based on Grade 1, which offers the highest level of durability.

There is a reason many commercial garages and storage facilities have roller garage doors. They stand out as one of the most secure options due to their unique design. The compact installation and absence of visible leverage points on the sturdy aluminum curtain make them a formidable obstacle for potential intruders. 

If you’re having an issue turning the key inside a lock, chances are there is dust or dirt buildup within the cylinder. The easiest solution is applying a dry lubricant to the lock, which loosens the dirt buildup. You may need to turn the key a few times for it to work properly again.

When it comes to how to get a stuck key out of a lock, the simplest way is to use some kind of lubricating substance. One option is to apply graphite powder while wiggling the key gently. As the graphite fills the lock, jiggling should loosen the key enough to allow you to pull it out.

Several types of deadbolts are available, including single-cylinder, double-cylinder, rim, smart, and electronic deadbolt locks. The most common type found in U.S. homes is the single-cylinder deadbolt, which uses a key on the exterior and a thumb turn on the interior. A double-cylinder deadbolt features two locking mechanisms and requires a key to be operated from both the inside and the outside.
