Keyfob replacement question - original half works

I finally jumped on the prius bandwagon, and so far it's been sorta fun/sorta worrisome. lol I got a 2008 with 129k miles for $3,800. Battery seems good (but it only sometimes shows green when I drive, it's usually blue if that matters). I averaged 42mpg with hwy driving around 60-65 and interstate driving around 78. I assume everything is decent. I took it to Toyota today and got an oil change and inspection. The only thing it needed was a new belt at $90. It's in good shape inside and out, so I hope I get many many miles out of it. The only problem I encountered was today when the heads up display didn't come up, but the car ran ok. I quickly found out how to reset it by unplugging the battery clip. Toyota said the 12v was fine, but I know how these things can work. A bad cell can act up randomly, but pass inspection for a while.

On to the real question. I didn't know I had a half-baked keyfob(i was busy inspecting this in other places, and it was a private party sell from 2 1/2 hours away. I didn't realize this until I was already on the way home). It only has one remote, and at first, it only started the car while inserted, and you had to unlock the car with the key. The proximity sensor didn't work and the lock/unlock buttons didn't work. I replaced the battery in it, and now the proximity sensor works, and the autostart without inserting works. However, the unlock/lock still doesn't work. The remote was damaged, so I'm excited to just have the other back. My question is do you think it's worth buying a used/new silver logo and having Toyota do a completely new programming on it for $105 labor, or should I just get a cheap eBay black logo to have for starting the car and the key to unlock it, and program that feature myself? My wife will rarely drive this (she has a 2015 Sienna), and other than the annoyance of always remembering to manually lock it, with the smart unlock I don't really care about the missing buttons. I assume I can't program a silver or black to have the buttons since my buttons don't work and they are needed in the chicken dance. Local locksmith quoted me 240 for a silver programmed, while the toyota dealer quoted me 225 for the fob, another 45 for the metal key!, and 105 for programming. They did say that if I pay 105 for programming, I can program as many as I want. I'm unsure if they knew the fob only partially worked.

 

My problem is the home-based programming requires working fob buttons, which I don't have. If I go to the dealer, can they even program a new fob to the car without messing up my current one? I don't think it's worth all the hassle to just get back button lock/unlock. I've been driving a 99 Camry with no fob and a 96 s-10 with no fob. Just having the smart door unlocks and keyless start is already an upgrade. It was a cheap car, and it isn't worth spending all this to fix items that are not really necessary. The only thing I want to put money into at this point is upgrading the stock stereo. New radio, speakers, and a little sub under the seat is all I"m looking for.

 

im paying for one with a locksmith to use the software.

 

i just want a fully working key to start with. this is a new car to me, so i will "invest"
