"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."

"There were many things wrong in my computer (my fault and letting grandchildren on computer) Robert was so helpful, gave me many good instructions to keep everything safe, which I have written down, feel like I have a new computer. He was so excellent and experienced, took his time and was meticulous about what needed to be done. He was a pleasure to work with and I will use this company again! Linda Disy"

"Choice responded quickly but the insurance plan does not pay for all doors to be re-keyed unless you have very few locks. The number of locks covered by the insurance is determined by keyholes, not doors! (Read your policy!) You will likely have to shell out some money to have this essential new-home service if you have more than four keyholes. The locksmith they called was EXCELLENT and made all our locks completely functional. We will happily hire the locksmith again (R.L Locksmith LLC). We paid $201.81 (plus another $50 for some door re-alignment not included in the re-keying benefit) and Choice paid $100 for the job."

"I have worked with Richard (owner) for about a year now. Before knowing him I was always confused about how to get some work done in the house. I never had a reliable person to turn to. Since knowing Richard I do not have to worry about whom to ask for any help I need around the house. I can depend on him to find the right person to do any job for me. It is almost as if he is a part of our family. We have put our house on sale and he made sure everything was well taken care of and we were completely satisfied. I would recommend him highly for any work. He has very skilled people working for him."

Locksmiths questions, answered by experts

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. 

Regrettably, entirely pick-proof locks don't exist unless you opt for keyless varieties. Locks advertised as "pick-proof" are, in reality, more resilient against lock-picking and bumping attempts because of complex mechanisms consisting of pins and sidebars. These locks work like this—they assign two tasks to the key, enhancing security by making unauthorized entry more challenging.

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.

Keyless locks are often considered safer since they’re protected by passcodes instead of a physical key, making it harder to be picked. However, they are not infallible. And like all electronic devices, outdated models are more prone to problems and safety concerns. If you’ve experienced multiple lockouts in the past year, or your lock is responding slower than usual after you key in the passcode, it might be time to upgrade to a newer one. Even if your lock is working fine, you should still change your access code at least twice a year.

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.
