This is the same link I used to order the blanks I have. Do not use this link, turns out it is the wrong blank in the first place. The link is supposed to take you to the blank ZD23RT5 which according to another web site is the correct blank. In fact if you look at the title that is where it says it will take you, but in fact the key shown is ZA-9.P
I ordered two of these thinking I was getting the 23RT5 and got the ZA-9.P instead. The ZD23RT5 is a much more expensive blank. Below is a copy of the web page, note the title has the correct blank number but in smaller print below it actually is ordering the ZA-9.P:
"Aprilia Scotters Transponder Key RW (ZD23RT5) JMA
KB-TP05ZA-9.P
Your Price: $7.65
In Stock
Item Number: KB-TP05ZA-9.P

Below is a link to the other web site that shows the correct blank

Note the considerably higher price for this blank.
I went ahead and had one of the ZA-9.P cut to see if it would open the trunk, It Will Not, so do not waste your money.
So still don't know whether the ZD23RT5 is the correct blank for the 14 or not. But given the price of the blanks I might just get another spare from BRP
