I left a message for another locksmith who advertised early hours but never returned my call! Since my sliding door to the terrace (ground floor) could not be locked due to a key broken into the lock, I was quite concerned. So I waited till Mosman Locksmiths opened, and was able to book a locksmith for the same day. Locksmith Pete arrived promptly and took very little time to fix my lock, at a reasonable price. In future, I will call you first! Thanks.
