"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."

"When I called around for quotes and to make the appointment, AA Key & Lock had clear upfront pricing and answered all of my questions. They had several options to find a convenient time for the service. They were able to rekey front and back door and install deadbolt on basement door for a newly purchased home in about an hour."

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.

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.

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.

Aside from the labor costs, several other factors can impact the cost of hiring a locksmith. If you can avoid services during off-hours, you can save on fees often charged for urgent requests. Consider additional factors such as:

  • Type of services required

  • Emergency call fees

  • Home and lock location

  • Number of locks to repair or install

  • Peak hours

  • Type of locks

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.
