"I called Alarm Protection Group AFTER my office was burglarized. Now I feel SAFE. William is great to work with. He's neat and tidy, prompt, presentable - not a butt-crack type of guy, and he doesn't leave a mess in his wake. He's also knowledgeable about the equipment and only uses high-quality products."

"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."

"Grand Handyman is truly amazing. I reached out for one job with a dryer vent, and while he was here he ended up doing two more! Fixed a leaking toilet base and a broken fence gate. He handled every job with ease and I wish I could give him ten stars! He went above and beyond!"

Locksmiths questions, answered by experts

If your key breaks in a lock, first remain calm and avoid forcing the broken piece further in. You may be able to remove it yourself if a portion of the key is still protruding from the lock. To aid removal, lubricate the keyhole with a graphite-based spray. Then, try using tools like pliers, tweezers, a bobby pin, or even a jigsaw blade to gently grasp and pull the broken piece out. If these methods don't work, you can't reach the key, or you're concerned about damaging the lock, it's best to call a professional locksmith for assistance.

Lock bumping is a technique locksmiths use to quickly and quietly open a pin tumbler lock, typically found in most types of deadbolts. It involves inserting a specially crafted key, or bump key, into the lock and tapping or "bumping" it with a mallet or similar tool. The force applied causes the lock's pins to jump momentarily, allowing the lock to be turned and opened. Unfortunately, thieves also use this technique to break into homes. Luckily, products like a deadbolt strap will fortify your lock.

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.

Smart deadbolts are a worthwhile investment for homeowners seeking more convenience, flexibility, and advanced features than a traditional deadbolt can provide. While a strong conventional deadbolt offers sufficient security for most, smart deadbolts provide significant upgrades.

Key benefits include keyless entry via smartphone, keypads, or biometric sensors, and the ability to lock or unlock your door remotely. You can also manage access for guests by creating temporary codes, eliminating the need for physical keys and the risk of them being lost or duplicated. Many models integrate with smart home systems and offer features like automatic locking, entry-exit monitoring, and tamper alerts with encryption for enhanced security.

However, there are downsides to consider. Smart deadbolts are more expensive than their traditional counterparts and rely on batteries and wireless networks to function. This dependency introduces potential vulnerabilities, such as hacking by skilled intruders and privacy concerns. Installation can also be more complex. Despite these drawbacks, the added layer of convenience and protection makes them a compelling option for many.

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 inspect your locks regularly. A higher grade lock provides you with more cycles than those with a lower grade.
