Problems with locks often come unannounced leaving you unprepared for facing the worst and if that problem comes during a weekend where most of the business have a holiday then it gets really difficult for you to handle. Hence, do conduct a detailed enquiry about your local locksmith and find out whether he is able to work weekends also. If he does, you should make a note his number somewhere where you can have easy access such as your mobile phone or personal diary so that you don’t forget it in case an emergency arises all of a sudden.
