Locks provide security against burglars and thieves. There are many types of locking systems available are the two popular types are UPVC locks and Padlocks.

• UPVC door locks are used on plastic or wooden doors. The UPVC multipoint locks consist of several small locks that go up with the strip of lock. UPVC locks fits with the door permanently along with a UPVC door handle. They provide good look for the door. If one requires replacing UPVC locks and install a new one, they should know the distance of centre of the door handle from the centre of the keyhole and measurement of the front plate of the lock from the centre of the keyhole.
• Padlocks are popular in usage. Padlocks may use the combination locking system, or they may use simple key-lock system. Some padlocks install a key-lock system and a combination system simultaneously. Strong iron padlocks can be used to lock the heavy doors, one may use lever padlocks too. Various padlocks can be used in various situations. While travelling, a smaller padlock may be used to protect the luggage.

Often we misplace our keys and then forget about it. Misplaced keys may force us to destroy the lock. Misplaced keys cause untidiness too. Key safes made for storing keys can be used to avoid such misplacements. While going outside, one may use the portable key safes; a fixed key safe can be used at home or office, to keep all the keys intact at one place.
