I needed two locks changed and one door opened (the tongue of the lock had broken off in the door and so we couldnt open the door). I was more than impressed with service quality and cost. Mark is friendly quick and tidy and the cheapest locksmith by far on the northside - nearly 50% lower than any other locksmith on the north-side of brisbane. He returned my call in 2 MINUTES!!!! Was at my door step in half an hour, and had the jobs done in 15minutes. No Fuss, no mess. All round nice australian tradesman who I recommend to anyone and everyone.
