Locksets which come under the doorknob assembly are available in differing levels of security and wide range and variety of styles. They can be bought from any of the hardware store (Lowe's, Home Depot). These locksets can be ornate in brass and can cost from twenty dollars upto three hundred to four hundred dollars. It doesn't matter which design or style of lockset is being used, the procedure of installing or removing them is more or less same. Most of these sets are easy to install and can be easily taken apart, especially those which you might have bought from a specialty or department store. Amongst the most secure and inexpensive locksets are known as Brinks Locks.
Two basic locksets available are the spring latch and the deadbolt. Although spring lathes are much easier to install but the deadbolts are more secure.
The knob outside has a keyhole while knob inside has the button for locking.
1. Firstly, unscrew the inner knob. Usually it has 2 exposed screws; you simply have to remove them. Outside portion is free; inside half will pull off and hence by pulling it out, it can be removed. If you are not ale to visualize the screws, you should look closer and check for a small button along the shaft.
2. Then remove the cover finding small notched opening. Then slip your screwdriver and pop off the cover.
3. Remove 2 screws that hold the lock and the faceplate can be removed easily.
Assembling the locksets:
The procedure of assembling is the same as the dismantling but the only difference is that it is done in the reverse direction.
1. Firstly insert the lockset in the opening from the outer side.
2. Now, using 2 screws install the faceplate.
3. Snap the cover along the bent wire latch which holds it in position.
4. Then depressing the latch on shaft, slide the knob on the shaft.
5. At last, check your lock by locking and unlocking it several times and make sure that the key should move freely.
