Therefore, to prolong the useful life of your door locks, here are a few tips that will help you in their maintenance:-
a) Clean the locks
Locks are exposed to dirt and dust throughout their usage which tends to build up on its inside. This results in jammed locks.
Therefore, to avoid the gradual process of ending up with a jammed lock, clean them from time to time with special spray lubricants. It is recommended to clean the locks once every year.
b) Keep away from excessive force
It is advisable to avoid applying unnecessary force on the door locks as it tends to weaken them. All the excess force results in reduced strength, durability, and functionality.
c) Ensure proper balance
Note that the door should not lean or sag. This puts too much pressure on the locks and hinges which ultimately weakens its ability to function properly.
d) Use them consistently
Last but not the least, having the best door lock in the world doesn’t help if you don’t use it regularly.
Regular usage ensures that the lock is always in working condition and not jammed. This reduces your chances of getting stuck with a useless, inefficient lock.
All homeowners are aware of the risks involved with using old and worn-out door locks. Over the course of time, you may feel the need to change the locks to ensure that your house is secure.
Moreover, there are several relatively simple ways to achieve this.
The process of changing the locks on a door may involve replacing it or rekeying it.
Replacing a lock is pretty self-explanatory. It involves removing the existing lock and installing a new one in its place. It is ideal to replace the entire lock that has a damaged internal mechanism.
On the other hand, rekeying is a rather cheap option. It involves replacing or realigning the pins of the lock in order to match it to a brand new key.
Rekeying is considered suitable when you are moving into a new house and a lot of other people like contractors, agents, etc. might have the keys to your locks.
However, if you lose the keys somehow, it is best to change the lock. In such situations rekeying is not an option as the process requires the use of the original key itself.
