Quick answer: Whenever you move into a new home or apartment, change the locks (Baltimore PD), or rekey them so old keys stop working (Waco PD). A DIY rekey kit works if it matches your lock brand; otherwise call a locksmith. Renters: ask your landlord first.
⚠ Safety first:
- Keep at least one door or window per room usable as a quick fire exit; don’t let security hardware block escape (Seattle PD).
- Use the right screws and drill bits, and wear eye protection when drilling.
- If something feels wrong or you see suspicious activity, call 911 (Baltimore PD).

⚠ When to call a pro: a cracked or split door frame; locks or doors damaged in a break-in (report to police first); doors that don’t fit their frames; and any hardwired lights, doorbells or cameras that need new wiring; that’s a job for an electrician (see breakers and outlets). Renters: ask your landlord before changing locks or drilling. Renting? See what you can fix vs. call your landlord.
