"I would like to recognize employee Doug A at SafeStreet/ADT. We’ve had an old security system sitting in our house for over 15 years without service or functionality. He took the time to explain the differences between how the old systems work and how the new systems work. He was patient with us, and we are happy customers."

"Walter and Glen at Protect Your Home Group with ADT are the best people to talk to in terms of security alarm. Being a locksmith myself I know how important it is to deal with the right people. I referred a lot of customers to them and so far they are happy with their service. I myself got one for my house. Thank you for a consistent service and great deal."

Locksmiths FAQs, answered by experts

If you don’t have your original key, the easiest way to obtain a copy is to call a locksmith. For house keys, your locksmith has several options for configuring a new key: 

  • They can input a lock’s identification code into a database to obtain key-cutting instructions.

  • They could analyze the lock cylinder to determine how to cut a new key.

  • They can create an impression of the lock cylinder from which to cut a new key. 

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.

In general, keyless door locks are considered safe, and their security depends on the type and quality of the lock. They cannot be picked like a traditional lock and often include added features like biometric access, PIN codes, and smartphone connectivity, which can make them more secure. However, they are not without risks. Potential vulnerabilities include hacking for Wi-Fi-connected models, battery failure, power outages, and technical malfunctions. To maximize security, it is important to choose a reliable brand, stay on top of software updates, and perform regular maintenance. While the risks are different, keyless locks are not considered more dangerous than traditional locks.

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

Yes, with better technology now available, it’s possible to add a smart lock 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’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.
