Deadbolt Lock
This type of lock has such a name because the bolt requires no spring for it to be operated. It works through manual operation with a key or a thumb turn from the inside of a door. There can be single- and double-cylinder deadbolt. The former is operated by locksmith Singapore using a turn button on the inside and a key from the outside, while the latter is operated with a key on both sides.

Dummy Knob
This type of door lock is mainly used for decoration or applications that do not require a latch. Basically it is just a knob and has no latch mechanism to close. Sometimes referred to as dummy trim in Singapore, this type is offered in a wide selection of styles.

Entry Lockset
In this type, a professional locksmith in Singapore uses two knobs that can be locked from the outside and inside. The inside knob is locked by depressing or turning a button, while the outside is unlocked with a key. There are some models that must be locked on both sides using a key, while in other models, only the inside knob can lock or unlock both sides.

Handleset
This combines a lockset with a deadbolt in which it requires a key to lock or unlock from the outside and usually a pushbutton or thumb turn to unlock from the inside. This type of door lock can be installed by a locksmith as a single- or two-piece unit in Singapore.
