Hello, people,

For a 2007 Outlander XLS, I'd like to get a second F.A.S.T. "smart key remote transmitter", part # 8637A025, just in case I lose the one that I already have.
The problem… the local stealer/dealer wants $341, plus $94 for the blank key, plus $120 to program it. THAT's just bloody ridiculous.
For a Used one on Ebay, $285, with an already-cut key, plus programming somewhere.
And it would be even more expensive if I did not have the one fob that I got with the (used) vehicle.





Are there any electronics / radio waves experts out there?
WHAT makes this thing so much more expensive than the $10 Mitsubishi remote, part # Hyq12aba that fits some 2001 vehicles?
What does this thing do?, besides just receive and transmit a certain frequency?
I'm thinking that almost Any other model of key fob (from ANY car make?) Could be programmed to send/receive the needed frequencies.
Yes? No? WHY Not?

I'd really appreciate hearing your thoughts.
Thanks.
