Changing your locks may sound like a simple task, but this is true only if you know what you are doing. There are many different styles of handles on the market. The locking mechanisms on certain styles vary and each has a unique function. If you are going to change your locks, be sure to know what type works best and why. Here is some useful information on styles and basics of changing a lock. Knowing what the lock is used for is important in finding the style that best meets your security needs.

Free through Passage Handles: These handles are exactly as they sound. You will not have to worry about locks. They come in either a knob type handle style or a level style which is very popular. Before purchasing these handles, though, be sure you do not need a lock.

Privacy Door Knobs: These handles are often used in the bedroom or bathroom. You can unlock the door by either turning the knob or turning an extra switch on the inside of the door. These are great for those areas where privacy is desired most.

Security Deadbolt Lock: The single deadbolt lock is a great style lock is good for any entrance to the home, whether the front or back door. However, it is best to use this lock with doors that do not have side lights or a glass pane since entrance would be fairly easy. One would only have to break the glass and reach in to turn the knob. The double deadbolt lock can provide extra strength and security to your doors. It can be locked form the inside or the outside using a key. You can also add a chain, for example, to provide even more security.

Decorative Door Knobs, Deadbolt and Latch Set: These handles help improve your home's appearance. They are often placed on French doors. You can also use them on pantries if there is nothing hazardous inside, which should be kept from small children for instance. There are no locks on these decorative handles, but a little more security can be implemented with a decorative deadbolt and latch set. You can use these two pieces together or by themselves, depending on your needs.

You must now determine if the door handle you currently have is appropriate. To make this determination, you should first look at the latch plate. The hole may not be deep enough for a higher quality latch. Open and remove the existing latch plate, which is on the inside of your door. If it does not fit into the old hole, you will need to chisel the hole to give it a deeper depth. Also, be sure to check that the plunger for the deadbolt lines up with the hole in the frame since the lock will not provide proper security otherwise. Adding longer screws into the pre-drilled areas on the latch plate can add extra security.
