Your door locks are the first line of defense between your family and the outside world. But most homeowners only think about changing their locks after something has already gone wrong. Here are five clear signs that it is time to call a locksmith and upgrade your home security — before a problem occurs.
1. You Just Moved Into a New Home
This is the single most important time to change or rekey your locks. When you buy or rent a home, you have no idea how many copies of the key exist — previous owners, real estate agents, neighbors, contractors, cleaning crews, and former tenants may all have keys that still work on your locks.
At minimum, rekey your locks the day you move in. If the hardware is old or low-quality, consider a full lock replacement with better-grade deadbolts.
2. Your Keys Were Lost or Stolen
Lost your keys at the gym, had your purse snatched, or left them at a restaurant? If you cannot account for every copy of your house key, treat the situation as a security breach. A stranger who finds your keys may be able to identify your home from other items (a gym membership tag, a mail piece in your bag, a car with your registration in the glove box).
Rekeying your locks immediately after losing keys is fast (10–15 minutes per lock), inexpensive, and gives you full peace of mind. Call (972) 544-4574 for same-day service.
3. Your Lock Is Stiff, Sticky, or Hard to Turn
A lock that requires jiggling the key, lifting the door handle, or pushing extra hard to engage is not just an inconvenience — it is a sign of internal wear or a misaligned door frame. A worn lock cylinder can fail entirely at the worst moment, leaving you locked out of your own home or unable to lock it securely.
If a shot of lubricant (graphite or dry teflon — never WD-40 on locks) does not fix it, the lock mechanism likely needs to be replaced.
4. You Recently Had a Break-In or Attempted Break-In
After a burglary or attempted entry, change your locks immediately — even if the intruder did not succeed. Look for these signs of tampering:
- Scratches or score marks around the keyhole (from picking or bumping tools)
- Bent or damaged strike plate or door frame
- A lock that now turns more loosely than before
A compromised lock should never be trusted again. Our locksmiths can also assess and reinforce your door frame and strike plate to prevent future forced entry attempts.
5. You Had a Major Life Change
Change your locks (or at minimum rekey them) after any of these situations:
- A roommate moves out — especially if the separation was not amicable
- A relationship ends and an ex had a key
- A contractor, housekeeper, or pet sitter who had temporary access is no longer in your life
- You fired a house manager or property caretaker
- A family member who had a key has passed away and you do not know who else may have copies
In all of these cases, rekeying is usually the fastest and most affordable solution since the locks themselves are typically still in good condition.
