Customers say: Super punctual

"I was extremely happy with Hank the owner of Standguard Security Inc. I called Hank early in the day for information about an alarm system and he promptly came to my house that same day in the evening for an estimate and other options that he presented to me for my needs. I called him back and we set a time for the installation of a new system that was free ( just needed to sign up for a monitoring service). The day of installation Hank showed up with his tech guy Chris and promptly started to get to work. Chris the tech guy / installer was great and made sure everything was working correctly and answered all of my questions before leaving. They both were professional and I am very happy with the whole process."

"Our dealings with Protect Your Home/ADT were delightful. We received a call back very fast after requesting a quote through Angie's List. We were able to complete everything on the phone; there was no paperwork or downtime. I had to call Customer Service with a question about the keypad, and they ended up telling me other helpful details on top of my original question."

"Eddie was great to work with! We had a limited time frame to adhere to town inspections and Eddie and his team knew exactly what we needed and quickly got the job done. The results were great and even the inspector acknowledged the impressive repair. They were able to put a knocked out garage wall back on the foundation and repair the interior dry wall. I would recommend this company for any professional contract work due to their reasonable price, ease to work with and quality of work."

Locksmiths FAQs, answered by experts

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.

Expect to pay between $50 to $200 if you hire a locksmith to change your locks. That figure includes labor and the cost of basic hardware. The cost will naturally be higher if you plan to install more expensive locks, like smart locks, and if you need a lot of them.

Homeowners can save money by replacing locks themselves. A typical rekeying kit costs about $10 to $25. The only additional cost is purchasing new house keys, and those are no more than a few dollars per key. If you want to replace the locks on your own completely, the main cost is the price of the locks themselves. A standard knob-style lock starts around $25, while electronic locks and smart locks will run in the hundreds of dollars. The only additional tools you should need are a tape measure, screwdriver, and screws if they are not already provided.

Lock picking is a relatively subtle method of unauthorized access, making it hard to detect. But there are telltale signs to look for. First, look for scratches or tool marks around the keyhole or the lock's surface. Also, check for loose or misaligned components, like a wonky strike plate, which could indicate tampering. Consulting a locksmith or security professional for an assessment can provide valuable insights, too. Investing in high-quality locks and considering additional security measures, like security cameras, can help deter potential intruders and enhance your overall safety.

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.

It is best to use a dry lubricant, such as a Teflon-based option, for door locks. Unlike popular oil-based lubricants, dry lubricants leave a non-stick, water-repellent coating that does not attract dust, dirt, and other debris. Using an oil-based lubricant can cause these particles to build up inside the lock, making it difficult to operate or even damaging the internal mechanism. You can find dry lubricants, some of which are made specifically for locks, at most hardware stores.
