Q: Can you put a smart lock on a sliding glass door?

• <div><p>Yes, with better technology now available, it&rsquo;s possible to add a <a href="https://www.angi.com/articles/keyless-lock-good-regular-deadbolt.htm">smart lock</a> 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&rsquo;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.</p></div>

Q: Can you tell if someone tried to pick your lock?

• <div><p>Lock picking is a relatively subtle method of unauthorized access, making it hard to detect. But there are telltale signs to look for. First, look for scratches or tool marks around the keyhole or the lock's surface. Also, check for loose or misaligned components, like a wonky strike plate, which could indicate tampering. Consulting a locksmith or security professional for an assessment can provide valuable insights, too. Investing in high-quality locks and considering additional security measures, like security cameras, can help deter potential intruders and enhance your overall safety.</p></div>

Q: Can I change the locks myself?

• <div><p>The good news is that, yes, you can change locks yourself. Many people find it&rsquo;s an easy DIY project that requires few tools and not much expense (depending on which lock you&rsquo;re installing). If you have trouble with any part of an installation, you can always call a locksmith to help finish installing them.</p></div>

Q: What deters burglars the most?

• <div><p>Security systems are one of the measures that deter burglars the most. Research suggests most burglars look for signs of a security system before going in, although the presence of a security system doesn&rsquo;t automatically mean they won&rsquo;t enter the home. However, a security system with cameras can decrease the chance of a burglary overall.</p></div>

Q: Can you pick a lock without a keyhole?

• <div><p>It&rsquo;s possible, but depends on the design of your lock. Some door locks that lack a keyhole do boast a small hole on the exterior handle or knob. This hole&rsquo;s primary function is to allow water to drain out of the lock, in addition to giving homeowners an easy spot to insert lubrication. However, you can typically use a paperclip in this pinhole to unlock the door by manipulating the mechanism inside. </p></div>
