Nismo Key?

[Addicted2Kouki]

Anyone know where I can get this key?

I got one of them when I first bought my car some years ago.
A couple months ago I got pulled over and searched for about 1 hr.
They saw this key in my wallet because it was my spare and confiscated it.
I didn't really miss it until now.

Problem is...these have been discontinued.

I'm feeling a bit nostalgic.
Anyone wanna help me out? possibly point me in the right direction...
Searching usually puts me in another dead end because its discontinued.
