"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."

"We were VERY happy with Don's performance and plan to hire him again for work in one of our bathrooms.   He was on time, professional, and very knowledgeable about many areas of home remodeling and repairs.   In addition to his friendly demeanor,   he also gave us some great suggestions to save us some money.   He worked non-stop for the time that was agreed to via the Angie's List Coupon.     Across the board,  a GREAT experience!"

"James and his team did a good job on renovating our whole house. Before choosing James, we compared a few companies. We made our mind to use his team because he made us feel comfortable to work with. We are 1st time home-owner so finding a contractor who has the patience for us and the knowledge to walk us through decisions when buying materials are very important. James is the one met our requirement. We have 5 bedrooms 2 baths. It took about two months and half to finish because certain materials we ordered did not arrive on time. During the renovation, there were unexpected issues that James discovered, but he was always able to figure out a solution that falls into our budget. I would recommend them to my friends who are in need of a contractor. Oh, BTW, I like the music turned on when they were doing the work. A few cool guys to work with, and they made the stressful renovation project a little more enjoyable."

"Prompt, reliable, and professional service. Good communication with Steve via email and Dennis on site before, during, and after the project was completed. Fair price for the job and good workmanship. I have already recommended them to others. I had them replace the railing, treads, and bottom platform of an outdoor staircase leading up to a second story deck."

I’m a reliable construction and maintenance professional with hands-on experience in residential repairs and renovations. I currently work as a maintenance technician for a large property, handling everything from small fixes like lighting and fixtures to larger projects such as laminate flooring, sinks, and vanities.\n\nPreviously, I was a project manager overseeing full kitchen and bathroom gut renovations, while also working hands-on from demo to installation. This gave me a strong understanding of doing jobs efficiently and to a high standard.\n\nI take pride in being detail-oriented and delivering quality results that last. I’m also honest and upfront—if something is outside my expertise, I’ll communicate that clearly. With strong customer service skills, I focus on making every job smooth, professional, and stress-free for the customer. \n\nIf you’re looking for someone reliable, hardworking, and committed to quality, I’m here to help get the job done right.\n\n

Locksmiths questions, answered by experts

If part of the key is protruding out of the lock, you can use a pair of needle-nosed pliers or tweezers to gently turn the key in the lock to open the door. If the key is fully inserted into the lock, you may also be able to use a key extractor to help turn the key into the unlocked position. 

But if the key breaks off halfway into the lock or you simply can’t reach it to help engage the unlocking mechanisms, you should probably call a professional.

Rekeying is typically cheaper than replacing locks. Professional rekeying costs between $40 and $160, sometimes with an additional fee of $15 to $40 per lock. A locksmith's hourly rate averages around $75. If you do it yourself, a rekeying kit can cost as little as $10. In contrast, replacing a lock costs between $130 and $500, with an average of around $315, depending on the hardware and lock type. Rekeying is a simpler process that changes the key for your existing lock without replacing the hardware. It is a good option if you have a quality lock that works well, you've recently moved, you've lost a key, or you need a quick security upgrade. The best choice depends on the condition of your current locks.

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.

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.

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.
