"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"

Locksmiths FAQs, 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.

There is a reason many commercial garages and storage facilities have roller garage doors. They stand out as one of the most secure options due to their unique design. The compact installation and absence of visible leverage points on the sturdy aluminum curtain make them a formidable obstacle for potential intruders. 

When it comes to how to get a stuck key out of a lock, the simplest way is to use some kind of lubricating substance. One option is to apply graphite powder while wiggling the key gently. As the graphite fills the lock, jiggling should loosen the key enough to allow you to pull it out.

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. 

Lock bumping is a technique locksmiths use to quickly and quietly open a pin tumbler lock, typically found in most types of deadbolts. It involves inserting a specially crafted key, or bump key, into the lock and tapping or "bumping" it with a mallet or similar tool. The force applied causes the lock's pins to jump momentarily, allowing the lock to be turned and opened. Unfortunately, thieves also use this technique to break into homes. Luckily, products like a deadbolt strap will fortify your lock.
