  13. Deadbolt Lock : one of the most secure types of locks, a deadbolt extends a solid metal bolt into the door jamb, making it resistant to forced entry.

The choice of lock depends on factors such as type of door, the level of security required, an personal preferences. For optimal security, its common to use a combination of different locks, such as a deadbolt in conjunction with another type of lock.
