Q: Should I change the locks when I buy a new house?

• <div><p>Yes, you should change the locks as soon as you can after completing the purchase of a house. This is a matter of privacy and security, as you have no idea how many copies of the keys the previous owner made. You can change the locks yourself or hire a pro to replace or rekey the lock, which costs <b>$50 to $100</b>. </p></div>

Q: How do I fix an electronic door lock?

• <div><p>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. </p></div>

Q: What is the difference between a deadbolt and a regular lock?

• <div><p>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.</p></div>

Q: When should I rekey my locks versus replacing them entirely?

• <div><p>Rekeying a lock changes the internal mechanism so that a new key works, while replacing a lock involves swapping out the entire hardware. Rekeying is a good, cost-effective option when you want to ensure old keys no longer work, such as after moving into a new home or losing a key. It's also ideal if you want to keep your existing lock hardware. You should opt to replace the locks entirely if you want to upgrade to a more secure or different style of lock, if the current lock is old or damaged, after a break-in, or if too many copies of the old key exist.</p></div>

Q: Is it possible to pick a deadbolt lock?

• <div><p>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 <a href="https://www.angi.com/articles/types-of-deadbolts.htm">types of deadbolts</a> 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. </p></div>

"I had a security system in place that had transferred ownership to 3 companies in total. I needed service on the system and received poor customer service and outrageous pricing for a small service needed. That inspired me to look elsewhere for a new security system provider. I came across Jeremy and Larry from 1st Security LLC and all I can say, being a person in the service industry, they came through big time. Not only were they punctual and knowledgeable, they were plain old nice !!!! From the quote with Jeremy to the install with Larry, it was a pleasurable experience and one that I would recommend over and over again."

He spoke with me in a very professional manner and put me at ease right away.
The process was seamless and my request was delivered very efficiently. Within just a few hours of providing them with information, I was able to get feedback. Rob took the time to speak with me and answered all of my questions.
I will definitely be using them again in the future should the need arise, and I would definitely recommend them as being very efficient, professional and reliable.
