"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."

"ADT is the best company 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"

"Choice responded quickly but the insurance plan does not pay for all doors to be re-keyed unless you have very few locks. The number of locks covered by the insurance is determined by keyholes, not doors! (Read your policy!) You will likely have to shell out some money to have this essential new-home service if you have more than four keyholes. The locksmith they called was EXCELLENT and made all our locks completely functional. We will happily hire the locksmith again (R.L Locksmith LLC). We paid $201.81 (plus another $50 for some door re-alignment not included in the re-keying benefit) and Choice paid $100 for the job."

Locksmiths questions, answered by experts

A deadbolt differs from a regular lock in its design, construction, and security level. Regular locks are typically used for interior doors, such as for bedrooms and bathrooms, and provide minimal security. They are easy to install and use, often featuring a simple locking mechanism on the inside. In contrast, a deadbolt is one of the most secure locks you can install on an exterior door. Its internal construction is designed to withstand significant force, adding a crucial layer of security that can deter intruders. While deadbolts may be more expensive and complicated to install, they are cost-effective for the security they provide and are built to hold up to wear and tear.

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.

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.

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.

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.
