Make sure that before you move into your new home, you change all the locks, garage codes, and security codes. You don’t want the previous homeowners (or their friends) to have access to your house because you forgot this important step.
If you are putting this off, check for hidden spare keys on the property in places like the tops of door frames and under rocks on the porch. (But your best bet is to change the locks ASAP.)
Have extra keys made so you can get in if you’re locked out! You don’t want to have to chance breaking one of your new screens or windows by crawling through when you’re stuck outside. You can get hide-a-key rocks and figurines online, so hide one in your yard or garden and ensure you’re never locked out.
Reset any security codes — garage, alarms, even locks sometimes have security codes, so make sure you change all of the codes before settling into your new digs.
