Degol : Why you need a new door lock ?

If you’ve bought a home or rented a new apartment but haven’t changed the lock(s), you should get a new deadbolt, or at least have a locksmith install a new cylinder—the part the key goes into and that locks and unlocks the door. If you rent your place, you should also change the lock, either with a new deadbolt or cylinder, if your lease allows you to. The chief concern is what’s called key control. “Who knows how many neighbors have a key [to your existing lock]?” said locksmith. “How many ex-boyfriends or ex-girlfriends have a key? They may be lying in the yard in a hide-a-key rock. Who knows?”

Besides these specific concerns, your locks may also simply be old, meaning worn out, outdated, or both. Lock technology—specifically resistance to lockpicking and other forms or stealth entry—has advanced significantly in the last decade.
