Yes—you should change access when a roommate moves out. In most cases, rekeying is the fastest and most cost-effective way to invalidate old keys while keeping your existing hardware. Replacing the locks makes sense if the hardware is worn, builder-grade, damaged, or you want an upgrade like a smart lock or higher-security deadbolt.
Even if the roommate was a friend and returned their key, you can’t know how many copies exist.
*Local note:* Sugar Land’s rental market and roommate turnover make this a common situation in Fort Bend County—getting ahead of it prevents awkward problems later.
Keys are easy to copy. Hardware store duplicates are fast and cheap, and people often make “just in case” spares without thinking about the long-term security risk.
Rekeying gives you certainty: once it’s done, every key cut before that moment stops working.
| If this is true… | Choose | Why |
|---|---|---|
| Locks are in good condition (Grade 1–2) | ✅ Rekey | Fast + affordable |
| Locks are sticky, old, or unreliable | ✅ Replace | Rekeying won’t fix worn mechanics |
| You want to upgrade security level | Replace/upgrade | Better hardware + better cylinder |
| You want smart lock features | ✅ Replace | New hardware required |
| There was conflict / safety concern | ✅ Rekey ASAP (or replace) | Close the gap immediately |
If you have immediate safety concerns, prioritize personal safety first and contact the appropriate authorities. Locksmith services should only be requested by authorized occupants/owners.
