"Erwin was professional and thorough. He understood our needs and had the perfect solution and executed it. He was extremely responsive, even during the evening. He also went above and beyond by anticipating the style of an appropriate doorknob according to photos he had seen. And besides all this, he has a respectful and friendly demeanor. Highly recommend Capitol M. Locksmith!"

"Every one was on time when it came to installing our security and automation system. The installation advisor kindly asked we leave a review and we are happy to. Using the Safe Streets Group is a good decision. Many thanks to the advisor that helped us."

"I was told arrival time would be 30-40 minutes. It was much longer (over 1 1/2 hours). But he did a fine job when got there. The real problem was the home advisor system. I had multiple companies contacting me and after I contracted with one, another called and lied, saying the locksmith in route did not work for company and saying he was coming instead. What a fiasco. I was at work and had just had a home break in. It was atrocious. I will not use home advisor again."

"I can’t say enough great things about Walter! He completed multiple projects in my home, and every single one was done with precision, professionalism, and attention to detail. From start to finish, he was reliable, communicative, and clearly takes pride in his work. He showed up on time, came prepared, and handled everything efficiently—no shortcuts, just quality craftsmanship. What really stood out to me was how he took the time to explain things, offered helpful suggestions, and made sure I was completely satisfied before wrapping up each project. It’s not easy finding someone you can trust in your home, but he exceeded all expectations. If you’re looking for someone dependable, skilled, and professional, I highly recommend him. I will definitely be using his services again!"

"After my husband and I had worked for hours trying to repair our boxsprings we broke down and called for help. Bobby Nesbitt was the man who saved us from another horrible night sleep. We called him at 5:00, hoping to have him put us on his schedule but we were amazed he said he could come that night at 8:00. He took one look and figured it all out. He was fast, knowledgeable and couldn't have been nicer. We will call him again when we get our list together. I've already told my friends about the wonderful service he gave us. Thanks Bobby you're the best."

Locksmiths questions, answered by experts

Deadbolts are solid and durable as can be, but the pin and tumbler can still be forced open, thus making this type of lock susceptible to picking. Most types of deadbolts are harder to pick than a traditional spring-based lock, though. It requires a specialized lock pick and a tension wrench to align all of the pins, thus unlocking the door. 

Lock bumping is a technique locksmiths use to quickly and quietly open a pin tumbler lock, typically found in most types of deadbolts. It involves inserting a specially crafted key, or bump key, into the lock and tapping or "bumping" it with a mallet or similar tool. The force applied causes the lock's pins to jump momentarily, allowing the lock to be turned and opened. Unfortunately, thieves also use this technique to break into homes. Luckily, products like a deadbolt strap will fortify your lock.

It is best to use a dry lubricant, such as a Teflon-based option, for door locks. Unlike popular oil-based lubricants, dry lubricants leave a non-stick, water-repellent coating that does not attract dust, dirt, and other debris. Using an oil-based lubricant can cause these particles to build up inside the lock, making it difficult to operate or even damaging the internal mechanism. You can find dry lubricants, some of which are made specifically for locks, at most hardware stores.

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.

Yes, keyless locks can deter burglars, mostly because they boost security and offer advanced features. Most models allow for unique codes or temporary access, making it harder for intruders to break in. Many of these smart locks even alert you if someone tries to tamper with them. However, you need to remember that while they provide an added layer of protection, no lock is completely foolproof. Pairing these locks with good security habits—like proper lighting and surveillance cameras—creates a strong defense to help stop intruders in their tracks.
