Yes, most pros encourage you to change your locks when you move into a new home. While the previous owner may hand you their keys, you have no way of knowing whether other copies exist elsewhere. Changing your locks as soon as you move in is a great way to ensure that you can enjoy new, fully functioning locks that will work with your unique key or code.

A keypad deadbolt, a lock requiring a code entered on a keypad entry, can be a convenient option for families with children coming in and out and needing access to the home. It can also offer an easy solution if you rent your home out, since you can easily change the code as needed. So, depending on your home entry’s needs, a keypad deadbolt may be worth the extra expense.

If your door handle turns without opening, the most likely culprit is a loose or stripped spindle. This part connects the handles to the latch mechanism, and when it’s not properly engaged, turning the handle does nothing. Other issues might include a broken latch, loose screws, or even something small blocking an inner mechanism. In any case, it’s usually a matter of tightening, adjusting, or replacing a worn-out part inside the handle assembly—or calling in a professional to do it for you.

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.
