"I described my project to John (change two existing deadbolts and install three new deadbolts), he asked a few questions, and gave me a very reasonable price. He arrived on time, was very friendly, explained what he was doing, and worked steadily until the job was complete. He was very professional and answered my questions as the job progressed. He ran into some difficulty with one of my existing deadbolts but did not complain and did not charge me extra for his trouble. I highly recommend John. His prices are fair, he is a skilled professional, and he is easy to work with."

"SafeStreets provided an outstanding experience from start to finish. The installation was quick, and the technician explained everything clearly. The system works perfectly, and the home automation features are a huge bonus. Highly recommend SafeStreets!"

"RJ was very nice and very knowledgeable about his trade. He and his help did a good job, cleaned up the job site and even offered to come back and replace the lock when we purchased a new one. I would highly recommend him."

"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."

"I hired Mark with Anderson Diagnostics on 2 separate occasions. Both were very positive experiences. The first time Mark changed out interior and exterior door hardware, and did drywall/wall texture repair. The second time I hired him to paint the interior of my home as well as change the baseboards in my master bedroom. He does excellent quality work and communicates very well. I also feel like he has integrity. I plan to hire him for future jobs."

Locksmiths FAQs, answered by experts

Yes, you should always change your locks after buying a house. Do so as soon as possible after you move in. Otherwise, you won’t know who has working keys to the property, whether they’re spare keys or otherwise. If an intruder gains access to your house with a key, it may not be covered under your homeowners insurance.

First thing first: Make sure you’re using the right key. If it’s the correct key for your lock, there are a few reasons why it may not be working, like the key is worn out or the lock is jammed. Try lubricating the lock and pushing the door closed to ensure the mechanisms work correctly. If you’re still locked out, call in for help.

Several types of deadbolts are available, including single-cylinder, double-cylinder, rim, smart, and electronic deadbolt locks. The most common type found in U.S. homes is the single-cylinder deadbolt, which uses a key on the exterior and a thumb turn on the interior. A double-cylinder deadbolt features two locking mechanisms and requires a key to be operated from both the inside and the outside.

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. 

Always consider security a top priority in your home. Perform a safety inspection of your home. Look for broken locks and rusty deadbolts, and take an inventory of who has access to your keys.

Consider the locks on your shed, safe, and other household items. Professional locksmiths can help you determine the best safety and security options for your home and feel at ease.

When a locksmith comes to your home, ensure your safety by having the locksmith show identification and provide an itemized invoice that you can reference later.
