"It went great. They could have had a serviceman at my location within an hour. Instead the serviceman, Joshua, called to make sure I needed the service and approximately what it would cost to repair it. Instead, Joshua knew what the issue was and told me how to repair it myself. It's not so much that I got away without paying a minimal service charge, it's that I found a contractor I could trust. They will be my go-to locksmiths from now on."

"Every one was on time when it came to installing our security and automation system. The installation advisor kindly asked we leave a review and we are happy to. Using the Safe Streets Group is a good decision. Many thanks to the advisor that helped us."

"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."

"Chris was excellent! I highly recommend. We had a problem with our front door, literally for years. It continued to get worse and worse until it became a real problem. Chris and I diagnosed the problem, and Chris fixed it beautifully. It is such a pleasure to have our door work as it did when it was installed. He was prompt and went above and beyond. I will definbitely utilize Chris in the future"

"Alexander was very considerate about setting a time for the locksmith service and calling me regarding delays because of the horrible weather and road conditions that day. He carried all necessary parts in his truck. He was very efficient in getting the job done. I was very happy."

"Stanley was a great person to work with.  He was prompt and worked hard to get all of our locks on the same key and in working order.  We bought an older home and the previous owner had a different key for each door, he was able to put all doors on the same key and special ordered a cylinder for one of the locks as it was giving us trouble and an original lock dating over 70 years.  We appreciated all of his work and recommend him to anyone looking for a locksmith."

Locksmiths questions, answered by experts

Yes, as long as it’s thick enough for the deadbolt. Most interior hollow core doors are at least 1 1/2-inches thick, which is usually the minimum requirement for a deadbolt. You’ll want to find the lock block first before installing. Also, most hollow doors require additional reinforcement for locks, such as a reinforcement plate or plywood block.

It’s possible, but depends on the design of your lock. Some door locks that lack a keyhole do boast a small hole on the exterior handle or knob. This hole’s primary function is to allow water to drain out of the lock, in addition to giving homeowners an easy spot to insert lubrication. However, you can typically use a paperclip in this pinhole to unlock the door by manipulating the mechanism inside. 

It could be difficult to get in and out of a lock for several reasons, such as the keyhole needing additional lubrication. Particles, debris, and dirt can also get into a lock, making a key stuck (the lubrication can help with the removal). 

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. 

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.
