"I locked my keys in my car so I called around to several different locksmiths and Lowkey locks quoted me the best price and told me he could be there within an hour. He arrived in 30 min and it only took a couple of minutes for him to unlock my car. Brett was very professional and as I mentioned very quick. I was very impressed and will be using them again. I would recommend this company 100%"

"John was very professional and is very trustworthy. I hired him for an assembly project for my home gym. He did an exceptional job and was quick. It would have taken me hours to complete the work he did in a relatively short period of time. I highly recommend John."

"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."

Locksmiths questions, answered by experts

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.

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.

Typically, it can take around 15 minutes to rekey a lock. The time depends on the type of lock and how skilled you are at rekeying. The first time you rekey a lock, it may take a little longer. Once you get the hang of the process, it will move along much more quickly.

You might want to change a door lock entry code for a handful of reasons. The most common answers are extra security or a forgotten code. You may also find yourself in a position where you need to temporarily change the code to allow a guest to come and go freely but want to switch it back once things return to normal.

Most door knobs can be removed with a Phillips or flathead screwdriver. If you don’t have either of those available, a paper clip or small pin can sometimes work, but the extra effort may not be worth a quick trip to the hardware store.
