We have to choose different lock cylinder for different doors and using conditions.

Cylinder with one side knob and one side key, open or lock the door by operating the key from the outside, or turning the knob from the inside. Generally used for interior door and fire-rated door, it’s the most common cylinder type in the market.

Double side key cylinder, we can use the key to open or lock the door from the both side.It’s mainly used for high security doors, such as the entrance door.

Bathroom cylinder is the cylinder one side with knob and the other side with slot, you can open the door  by turning the knob from the inside, or rotate the slot by a screwdriver from the out side, it’s used for bathroom doors.

Half cylinder, one side with key, can only open by key from the outside, generally used for the repair and maintenance doors or storage room doors.

Cylinder length= door thickness + escutcheon thickness *2 (generally, there are 2 pcs escutcheon, inside and outside of door). If the mortise lock is not at the middle of the door leaf, you should measure the size and choose the unequal cylinder.

Otherwise, for rebated door, we use unequal knob cylinder generally, we have to confirm the cylinder size on the key side and knob side separately. 

There is no right or wrong answer when it comes to Normal Yale key VS Computer key. This is simply a difference in usage habits.

Generally, a cylinder with 3 YALE key or with 5 computer key.

For YALE key, it’s easy to make a copy, security level is not very high.

For computer key, you can open the cylinder by using the both side of the key, it’s more convenient, the computer key is difficult to duplicate, the security level is higher.
