"Making the appointment online was super easy. A woman called the next day to confirm, which was nice. The locksmith who arrived (Nick) was highly professional and friendly. He did a great job at an affordable price. I am very happy with Mass Lock, I'd use them again and would recommend them to anyone."

Customers say: Quick response

"Roy was a lifesaver! On a Saturday night I realized my house keys went missing and I got an almost immediate response when I reached out. I made an appointment with him for the morning and he called 15 min prior to tell me he was on his way. When he arrived he was a few minutes early. He had my condo door unlocked in less than 5 minutes and I thought what he charged me, for a house call on Easter Sunday, was very fair. I really appreciated how responsive and reliable Roy was. I will definitely recommend him next time someone I know needs a locksmith."

"Awesome Service! I hired recently to install two garage door openers. I am pleased with his service. I described him as a professional, punctual and knowledgeable. He knows what he is doing. He visited prior to start the project and described what will be needed to complete the project and show up exactly on time (sharp) and completed the job very neatly and professionally. The best part and extra mile he gave in the whole project was follow up after the job is complete which mostly no one does after receiving the payment. Thank you so much for the job."

Locksmiths FAQs, answered by experts

There are several situations when you should change or replace your locks to ensure your home's security. Key moments include moving into a new house, after a break-in or attempted break-in, or when a roommate or anyone else with a key moves out. It is also wise to change your locks if you lose your keys, especially if they have an address attached or you suspect they were stolen. Finally, if your locks are old, broken, worn out, or have become unreliable, they should be replaced.

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.

Smart locks offer a similar level of safety to traditional or conventional locks because they often use comparable locking mechanisms, such as deadbolts. The primary difference is the access method: smart locks use a login or code instead of a physical key, which adds convenience. While not inherently safer, some smart locks have added security features that can deter intruders, like shutting down after too many incorrect code attempts or being harder to pick. For the best security, it's recommended to combine any lock with other home safety features like motion-activated lighting, security cameras, and window and door sensors.

Using a combination of tools (often store-bought plumbing tools) and brute force, a burglar can easily snap the lock on a door. Snapping a lock aims to gain access to the cylinder inside, which holds the locking mechanism. Once the thief snaps the lock, they can pick the cylinder open and walk right in.

Lubricating a door lock is an important part of door lock maintenance. It involves taking the lubricant of your choice (it’s best to use whatever the lock’s manufacturer suggests) and spraying it directly into the keyway. Push and pull your key in and out of the lock to make sure it’s all the way in.
