"The first project I hired David for was to re-align my gutters and guards. The 2nd was to install security lights and the 3rd will be a new vanity and sink in the bathroom. He does great work, is efficient, fair priced and very professional. Highly recommended! Kerry in Shillington"

"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."

"Art Rosenberger was involved from the first meeting we had with him to completing the installment. He was very professional and put our needs first. He has an extensive knowledge of security systems and he customized our system to fit our needs without unnecessary add-ons. A great listener. After installing the system, he spent over an hour teaching us how the system works and how to use it, making certain that we "got it". The system is working flawlessly, we like the ability to control it from afar via our phones or computers. Mr. Rosenberger is clearly committed to excellence. This is a great service. Very personalized. We recommend Shield Security Systems of the Lehigh Valley with the highest possible confidence."

"Yes, the handyman did a great job. For a senior citizen, it's a little on the expensive side. Must budget my items that need fixing on a month-by-month basis; perhaps, establishing a senior discount would be nice. Otherwise, great people! Great concept!"

Locksmiths FAQs, answered by experts

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.

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.

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.

You can cut a door knob off using a sawzall, but you risk causing additional damage to the door itself. You’ll also need to completely replace the door knob, costing you extra money and another trip to the hardware store.

Newer, electric-powered door locks generally have a life span of five years or less. That’s thanks, in large part, to a phenomenon called planned obsolescence, in which products are programmed to need replacing after a certain amount of time. That’s also why older, manual, push-key locksets can last up to 30 years with regular cleanings and maintenance. When it does come time for a new set-up, know that the cost to change locks ranges from $130 to $500 on average.
