Thank you. Those are extremely useful answers. I found it quite difficult to gather up that information by contacting the hardwood/home improvement stores or locksmith companies themselves who for the most part ignored our group's effort no matter how many times we emailed or called them (several times each).
Just some follow up questions if you don't mind.
1. I assume the keys for these inline 5 or 6 pin locks are one-sided pin tumbler lock keys? Also, can you provide a picture example if possible.
2. Are there any other 1-2 very commonly used profiles besides LW4 (C4)?
3. How does the "do not duplicate" engraving on keys work in Australia? In the US, for example, it's just a suggestion or request, and has no legal weight. I found some differing/contrasting opinions on this based on my research of Australian laws.
Sort of more opinionated and less about key/locks business questions and more about Australian culture:
3. Are kiosks (DVD/Blu-ray or otherwise) considered popular enough in Australia? I know the country does have some like Hoyt's (Oovie). Do you think a key kiosk like minutekey be successful in a smaller market like Australia compared to the US where it has achieved success? Would people be willing to just swipe their credit/debit card in a kiosk machine and wait a few minutes for a duplicate key rather than get it cut at a hardware store or a professional locksmith?
http://www.minutekey.com/4. How do Australian companies/stores operate in your opinion? In terms of a revenue share model, what would you prefer or think a company like Woolsworth or Master's Home Improvement would prefer? I'm asking because Lowe's and Home Depot in the US just the current model.
Current Model
minuteKEY collects all the revenue from the kiosk
mK pays a commission (between 15% to 25%) paid to the retailer mK pays for the kiosk, and inventory
mK establishes its own field service network
New
mK sells the kiosk and the retailer or partner collects the revenue mK sells keys to retailer or partner
mK charges a monthly licensing fee for its software
Hybrid
mK collects all revenue from kiosk
mK pays a commission to the retailer
mK partners with an existing kiosk service organization
Anyways, no need to answer them all. Again, I really appreciate you taking the time to answer my questions and will definitely credit the website and your username if you don't mind when I list our group's resources. I spent an hour chatting with Master's Home Improvement yesterday and all I got out of them was the price of a regular and painted key which were roughly $2.50 (AUD) and $4.00. They said they cut all one sided keys. That's all their customer service team knew but I guess they aren't professionals to be fair and would expect the same at Lowe's or Home Depot here in the US.
Lastly, are you a professional locksmith yourself? It seemed like it when you suggested "my customers."
