It is significant to extract the broken key from your lock immediately for a number of reasons. Firstly, having a broken key within a lock can lead to damage of the internal components of the lock, especially when you try to carry out broken key extraction with improper tools. In case of damage to lock, this becomes an additional expense.
In case you break the key while the door is already open, you will not be able to lock the door and hence insecurity. Therefore, it becomes important to have the broken key extraction done immediately. Call a locksmith as soon as possible.
However, it is important that homeowners take preventive measures to avoid broken key cases. One of the measures is to regularly lubricate the lock. This ensures that the key moves smoothly within the lock and minimizes instances of broken keys. Also, homeowners should have spare keys in hand. This will assist to avoid overuse of one key. Also, if you notice that your key has slight damage, halt using it and change to the spare key.
