Programming credit card key yourself

Anyone have luck programming a credit card key yourself with tech stream or GTS+. Searched bunch of post looks like it’s been done on older tacos. Not trying to get raped at the dealer.
UPDATE
So I think I’ve got it. Tech stream soft ware 20$ cable and 25$ seed code 100$ OEM card key from eBay. I’ll post up once I’ve either done it or bricked my truck stay tuned.

I called dealer to confirm and it would have only been 180$ to program, probably should have just done that, but I’m in to deep now gotta see it thru.

 

maybe check some of the Lexus forums? I think they’ve had these credit card keys longer than us poors

 

How much dose the Dealer charge?

 

We’ve had it a good while, albeit unofficially…
