Tubular locks have got their name from the shape of the keyway which is circular. The tubular locks have a basic ring-shaped hole and in the middle it has a solid metal cylinder. There are about seven or eight pins in the ring gap. In a tubular lock the key pins are moved horizontally. The lock has grooves cut into the outsides of the ring shape. There is a specific way in which the key has to be inserted in the lock.

The tubular locks provide light – medium duty. They have a smaller rose and come in market with decorative levers. However, they have limited cylinder options, cannot be used on thick doors and the chassis is not operational.

Cylindrical locks are also a bored lockset. In the cross bore of these locks, a latch or bolt mechanism is involved. The cylindrical locks are quick and easy to install. The mechanism of the lock uses a series of different length of pins. These pins follow the pattern of the key. The pins take the correct positions, such that the lock is released when the key is inserted into the lock. There are five types of cylindrical lock, namely-

A) Euro Cylinder Locks

They are available in many sizes and many brands. They are also one of the most popular locks. The euro cylinder locks have three different locking options-

  • Single cylinder type– This type of lock can be locked from one side only
  • Double cylinder type-This type of lock can be locked from either side of the door.
  • Key and thumb turn option– This type of lock is opened by using a key on the outside whereas a thumb turn is used on the inside.

The euro locks are very popular because they have a wide range of varieties in order to accommodate the varying door thicknesses.

B) Oval Cylinder Locks

Apart from an oval shaped barrel and an oval mortise lock case; they are similar to the euro locks. The oval cylinder locks lacks the thumb turn locking option.

C) Mortise Locks

These locks are more significant than euro locks because they are larger and round. However, this big size serves as a disadvantage because it doesn’t fit every type of door or lockset. The biggest advantage of mortice locks is that, it consists of a threaded housing, which makes it more secure and hence very less vulnerable to breaking or snapping.

D) Key In Knob Cylinders Locks (KIK Cylinders)

Key in Knob is abbreviated as KIK. The KIK cylinder locks have a many locking mechanisms such as levers, knobs and deadlocks.
