"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!"

"I hired Cesar and his crew to gut and renovate multiple bedrooms a kitchen and 2 bathrooms. Cesar, Armondo and Benjamin were an absolute pleasure to work with. Their knowledge, expertise and craftmanship are top notch. Cesar is easy to work with and truly cares about making sure his customers are happy. Cesar has an uncanny knack for finding a solution to any problem he encounters. I found his pricing to be very fair and reasonable and I quickly learned I could trust Cesar. If you are looking to remodel, finish off a room or repair any part of your interior, Cesar and his team should be your first call."

"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

Yes, many locksmiths offer 24/7 emergency services for business lockouts, broken keys, and security breaches.

There are many types of deadbolts, but these tips work on most. First, address any grime buildup. A bit of WD-40 will loose up rust and dirt so the deadbolt can turn. Inspect the door and frame alignment if this doesn't resolve the issue. Adjust the strike plate or the deadbolt's position to improve alignment. If the problem persists, disassemble the lock to inspect for damaged or worn parts. If you are unsure how to do it, hire a local locksmith.

If your key breaks in a lock, first remain calm and avoid forcing the broken piece further in. You may be able to remove it yourself if a portion of the key is still protruding from the lock. To aid removal, lubricate the keyhole with a graphite-based spray. Then, try using tools like pliers, tweezers, a bobby pin, or even a jigsaw blade to gently grasp and pull the broken piece out. If these methods don't work, you can't reach the key, or you're concerned about damaging the lock, it's best to call a professional locksmith for assistance.

Begin by checking the power source, typically a battery or wired connection. Ensure the battery is installed correctly, has sufficient charge, and isn't corroded. If it's a wired lock, examine the electrical connections to confirm they are secure and free from damage. Additionally, inspect the lock's programming or settings. Confirm that user codes or access credentials are programmed correctly and that any remote control devices are paired and functional.

Yes, with better technology now available, it’s possible to add a smart lock on your sliding glass door. Smart locks can be easy for almost everyone in the family to operate and can connect to other safety features in the home, like smart lights. Plus, they’re harder for would-be criminals to pick. However, keep in mind that smart locks can potentially be hacked, and some completely rely on phones or Wi-Fi, which can be an issue if the power goes out.
