Rekeying is one of those security tasks that's easy to put off. The lock works, the key turns, nothing obviously wrong. But there are situations where an unchanged lock represents a real and immediate security risk — and most Las Vegas homeowners don't act on them until something goes wrong.
1. You Just Moved Into a New Home
This is the most urgent case, and the one most often skipped. When you close on a Las Vegas home and pick up the keys from the title company, you are almost certainly not holding the only copies. Previous owners may have given keys to family members, housekeepers, dog walkers, neighbors with emergency access, and multiple contractors. Real estate agents often have a lockbox history that includes multiple showing agents. Rekey every exterior lock on move-in day — not eventually.
2. A Roommate or Tenant Moved Out
You may have gotten the key back. But did you get all the copies? Las Vegas is a high-turnover rental market, and we receive calls regularly from landlords in Henderson and North Las Vegas who discover a former tenant retained access to a unit after departure. Rekeying between tenants is the only way to ensure complete key control.
3. You Lost a Key
A lost key is the single most common reason Las Vegas residents call us for rekeying. The moment a key is unaccounted for — whether it fell out of your pocket at the Boca Park shopping area or was left in an Uber — the integrity of your home's key control is gone. Someone has your key and they may or may not know your address. Rekey immediately and don't wait to see if the key turns up.
4. You've Recently Had Work Done on Your Home
Home renovation is common in Las Vegas's growing housing market. Contractors, subcontractors, HVAC technicians, electricians — any of them may have been given temporary key access during a project. Once the project is complete, rekeying ensures none of those keys remain operational.
5. There's Been a Break-In in Your Neighborhood
A residential burglary nearby is a signal to review your own security posture. This is a good time to rekey, assess your deadbolt grades, and check your strike plate installation. Las Vegas communities like Summerlin and Henderson have active neighborhood watch networks — if your app is showing break-in alerts in your zip code, don't wait.
6. After a Relationship Ends
This is a sensitive but serious situation. After a romantic partner, spouse, or live-in family member moves out, any key they had should be considered uncontrolled regardless of what they say. Rekeying is not an accusation — it's a practical security step that applies in any key-change-of-occupant situation.
7. Your Locks Are More Than 10 Years Old
Lock cylinders wear over time. Pins wear down, springs weaken, and the tolerances that make a lock pick-resistant degrade. If your Las Vegas home has original builder hardware from a decade ago, a rekey combined with a security assessment is worthwhile. You may find that a cylinder upgrade during rekeying costs less than you expected and delivers meaningful security improvements.
