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.

Find a vetted and trusted locksmith to work on your home so you can feel comfortable and safe. Hire a professional with these qualifications:

• Search a verified directory of locksmiths near you, like those on Angi. 

• Check for an Associated Locksmiths of America (ALOA) logo on their website or company logo.

• Read company reviews. You can also check their social media pages.

• Ask for a pro’s credentials, insurance, licensure, and customer testimonials. 

• Check if the locksmith is knowledgeable about various topics, from decorative locks to the newest technologies on the market.

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.

There are many types of deadbolts, but these tips work on most. First, address any grime buildup. A bit of WD-40 will loose up rust and dirt so the deadbolt can turn. Inspect the door and frame alignment if this doesn't resolve the issue. Adjust the strike plate or the deadbolt's position to improve alignment. If the problem persists, disassemble the lock to inspect for damaged or worn parts. If you are unsure how to do it, hire a local locksmith.
