Have you ever handed your keys to a valet? Or give a contractor a spare key? There is a possibility that your keys have been copied or you have extra keys that are unaccounted for.
Re-key your locks any time you feel you might have misplaced a key or allowed a stranger to borrow your key. Weiser SmartKey Re-key technology makes re-keying fast and convenient, without having to replace the entire lock.
Locks are subject to wear and tear. Worn or rusted locks are a serious weakness in home security. Old, worn out locks are easier to pick and break, and they are more difficult to open legitimately with a key as time goes on.
Closely inspect deadbolts every six months for signs of tampering and excess wear. If your lock has severe tarnish, rust, or other visible signs of wear, it may be time to look for a replacement lock. If your lock is becoming increasingly difficult to open with the key, especially on cold nights, you need to replace or service the lock immediately to avoid an inconvenient malfunction that may leave you locked out.
