Locksmiths know how to operate on the different types of door locks

The locksmiths are trained on a number of different locking systems. These could range from the traditional lock and key systems to the most modern keyless systems.

Locks are the mechanical, electronic or biometric devices which are used to fasten a door or other similar objects. These require some kind of keying for them to open up. The traditional keys are mechanical whereas the modern ones could also be electronic ones. A locksmith gets to know about these different locks and key systems from the training institute which he joins. He can also learn the same from his senior or mentor or from his practical work experience.

Some of the main types of locks which are known to locksmiths are:

1. Privacy lockset: This type of lock has a locking button on the inside knob and there is no device to put in
the key on the outside. These are more appropriately used for maintaining the privacy, rather than being used for the security purpose.
2. Passage lockset: These are used inside the building, especially when there is a need to connect two rooms or passage to some hallway. These feature the non-locking knobs on each side of the door.
3. Dummy knob: These are just for decorative purposes and do not turn because these do not have any latching mechanism.
4. Entry lockset: This is the one which makes use of the locking knobs on both sides of the door, from the inside and from the outside. The locksmiths are familiar with the two variants of these locks. In one, the door might be latched from inside and it requires a key to open it from outside. In the second variant, both the locking and unlocking can happen from both the sides. These provide medium level security for the homes or offices
5. Deadbolt locks: Expert locksmiths generally considered these ones to be the safest bet for the security of the doors and hence, of the facilities. These do not have a spring to operate and these can be operated only manually. These also come in two different models. In single-cylinder ones, there is a turn button in the inside and is operated with a key from the outside. In the two cylinder ones, the turn buttons and the keying options exists each side of the lock.
6. Surface mounted locks: The locks which have been discussed above are fitted into the door frame. There might be some others which can be mounted on to the surface of the door and the bolt slides into a surface mounted strike. These are usually placed on the inside of the door.
7. Night Latch: This makes use of the large, spring loaded latch which automatically locks the doors when the door is closed. This is usually placed on the inside surface of the door.
8. Keyless entry systems: A locksmith is also provided training on the most modern key less entry systems. These are opened by entering the codes, or by bar code reading.
Professional training on all these and many more types of the locks and locking systems is what makes the difference to the practice of this profession by different locksmiths.
