"I had a great experience with this company, specifically thanks to their technician, Diego. He was highly professional, efficient, and fixed my door hinge in less than an hour. What really impressed me was his expertise; he went above and beyond by giving me some incredibly helpful recommendations on how to properly restore the vintage lock and handle on my 70-year-old door. Fantastic service all around. Highly recommended!"

"I would like to recognize employee Doug A at SafeStreet/ADT. We’ve had an old security system sitting in our house for over 15 years without service or functionality. He took the time to explain the differences between how the old systems work and how the new systems work. He was patient with us, and we are happy customers."

"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 FAQs, answered by experts

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.

When you take a key to a hardware store or a locksmith for copying, you can expect the key-cutting process to take as little as 30 seconds. The key copier will review your current key to decide on the correct blank. Then, your original key and the blank are inserted into a key duplication machine to cut an exact key copy. When it’s all said and done, you can have a new key in your hand in just a couple of minutes.

If you’re having an issue turning the key inside a lock, chances are there is dust or dirt buildup within the cylinder. The easiest solution is applying a dry lubricant to the lock, which loosens the dirt buildup. You may need to turn the key a few times for it to work properly again.

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.

Yes, you should change the locks as soon as you can after completing the purchase of a house. This is a matter of privacy and security, as you have no idea how many copies of the keys the previous owner made. You can change the locks yourself or hire a pro to replace or rekey the lock, which costs $50 to $100.
