"Frank is a really superb guy who's a gifted locksmith. And, furthermore, I really trust him. Let me be honest with you. I've always been anxious about hiring a locksmith. Frank, to me, had superb ratings on Angie's List. He engaged quickly during my quick call to him. We then communicated by text continually. He showed up in a quite impressive, branded commercial truck with all of the fixings! Great guy, very personable. He ably replaced the locks. Frank also checked out my other, external doors. He reinforced all lock plates with extremely long screws. I was impressed! I just wish I had more doors! (Just hire him!!)"

"Tim arrived and went right to work solving the problem. He explained exactly what he was going to do to get the lock to function properly. Needless to say he fixed the problem and I was able to get into the house. Reasonable rate also for the visit and repair. A good experience all around. Highly recommended."

Locksmiths questions, answered by experts

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.

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.

First thing first: Make sure you’re using the right key. If it’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’re still locked out, call in for help.

Whether or not keyless door locks are safe and trustworthy depends on the visibility of the programming code—and a trespasser’s determination. Even if you carefully guard entry and programming codes, those trying to break in may be able to crack open the lock’s faceplate with a screwdriver and change the codes. The same goes for manual models.

Some find smart locks the safest option because it’s harder to manipulate codes without access to your phone. But it’s possible to get hacked even then. Consider installing an extended security system, like door and window alarms or surveillance cameras, to enhance security. 

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.
