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: Should I change my locks after buying a house?

• <div><p>Yes, you should always change your locks after buying a house. Do so as soon as possible after you move in. Otherwise, you won&rsquo;t know who has working keys to the property, whether they&rsquo;re spare keys or otherwise. If an intruder gains access to your house with a key, it may not be covered under your <a href="https://www.angi.com/articles/how-to-get-know-your-homeowners-insurance.htm">homeowners insurance</a>.</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: What is the most secure type of lock for a house's exterior doors?

• <div><p>Security experts recommend deadbolt locks as the most secure option for a house's exterior or entry doors. Deadbolts provide the best security because they can prevent most types of forced entry and are harder to lockpick. Common types include the standard single-cylinder deadbolt, which is often found on front doors. For enhanced security, you can opt for a double-cylinder deadbolt, which requires a key to operate from both the inside and the outside.</p></div>

Q: How often should you change your locks?

• <div><p>Locksmiths recommend changing your locks once every seven years for the best security at your home. Locks can wear out over time, so you should <a href="https://www.angi.com/articles/6-keys-proper-door-lock-maintenance.htm">inspect your locks</a> regularly. A higher grade lock provides you with more cycles than those with a lower grade. </p></div>
