How much does it cost to rekey a lock?

• <div><p>Rekeying door locks yourself costs a fraction of what you would expect to pay a locksmith. On average, it costs between <b>$50 to $100</b> to hire a <a href="https://www.angi.com/nearme/locksmiths/">local locksmith</a> to rekey your house, though labor costs may vary based on where you live. For a DIY solution, you can expect to spend <b>$11 to $25</b> on a rekeying kit. </p></div>

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’t know who has working keys to the property, whether they’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: Why is my lock not opening with the key?

• <div><p>First thing first: Make sure you&rsquo;re using the right key. If it&rsquo;s the correct key for your lock, there are a few reasons why it may not be working, like the key is worn out or the lock is jammed. Try lubricating the lock and pushing the door closed to ensure the mechanisms work correctly. If you&rsquo;re still locked out, call in for help. </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: Should you replace old keyless locks?

• <div><p><a href="https://www.angi.com/articles/what-are-pros-and-cons-keyless-locks.htm">Keyless locks are often considered safer</a> since they&rsquo;re protected by passcodes instead of a physical key, making it harder to be picked. However, they are not infallible. And like all electronic devices, outdated models are more prone to problems and safety concerns. If you&rsquo;ve experienced multiple lockouts in the past year, or your lock is responding slower than usual after you key in the passcode, it might be time to upgrade to a newer one. Even if your lock is working fine, you should still change your access code at least twice a year. </p></div>

"This is the second time we used John. Since he was so good on our first project, it was an easy choice to call him again. This project was to replace rotted wood posts and railings on our front porch. As usual, John’s work was excellent. His attention to detail clearly separated him from many other contractors. John is easy to work with, does what he says he will do, communicated well, consults with you on any decisions and handles unexpected issues with ease. We will use John again for sure."
