    Anyone tried to have one of these smart cards programmed for the gen5 prius (prime) yet?

    Inspired from Lexus Credit Card Smart Key | PriusChat

    The 2024 Tacoma higher trims get two normal key fobs a credit card sized key fob
    Haven't figured out the part number yet though

    tacoma4g forum has a thread with pictures /card-key-style-keyfob-for-2024-tacoma-first-look.1990/
    definitely FCC ID HYQ14CBP

    Oddly enough, as far as I can tell the normal key fobs for the Tacomas are HYQ14FBX, which are the same FCC ID for my Prius Prime key.
    Maybe there's a chance that CBP is compatible with FBX?

    Hmmm. Tempting. Can't see why it shouldn't work. Need to be programmed at a dealer, of course, or someone with the top-level TechStream subscription that includes key programming.

    Looks like part number 8990H-A1010. Found it for $223.59 online($322.92 MSRP).

    Transmitter Sub-Assy, Smart Key Supply


    edit: I shot off an email to a parts department. If I get a reply, I'll post an update.

    Got a quick reply. The dealership says it only works with Tacomas. I don't know if I 100% believe them, but I'm not sure I want to spend $225 to test it. If a person wants to test it for "cheap", they could try a used unlocked Lexus HYQ14CBP off ebay. Cheapest ones seem to be running $65-$70.

    The part number helps a lot, thank you! I'll wait for the next 25% off sale at toyota autoparts and give it a try.

    Here it is on ebay for $135. I think the guy from tacoma forum is selling his. Same pic of key fob with credit card.

    I like that shape much more than the key fob. I also like not having to unlock my iPhone to get into my car every time when my hands are full.

    So I'm 99% sure this will work. I've purchased a smart card key and I've done the research but I'm still looking for someone who doesn't charge $250 to program it. Really hoping for something around $100

    Here's the research:
    https://www.toyotanation.com/threads/info-smart-key-card-on-the-avalon.1623584/
    poster notes that it is important for the ECU FCCID to match
    makes sense to me
    https://www.fcc.gov/oet/ea/granteecode

    I go to my prius manual
    https://assets.sia.toyota.com/publications/en/om-s/OM47F48U/pdf/OM47F48U.pdf
    jump to page 669 for the ECU
    FCC ID: NI4TMLF19D-3
    also 671 for the fob
    FCC ID:HYQ23ABN
    FCC ID:HYQ14FBX


    I pull up a tacoma manual
    https://assets.sia.toyota.com/publications/en/om-s/OM04011U/pdf/OM04011U.pdf
    jump to page 689 for ECU
    FCC ID: NI4TMLF19D-3
    sweet it matches
    fob
    FCC ID:HYQ23ABN
    FCC ID:HYQ14FBX
    FCC ID:HYQ14CBP

    matching FCCID
    Additional confirmation

    ah yep, for the lexus, nice

    Lexus RX500 manual
    https://assets.sia.toyota.com/publications/en/om-s/OM0E218U/pdf/OM0E218U.pdf
    page 636
    FCC ID: NI4TMLF19D-2
    prefix matched, suffix doesn't seem to matter

    So if anyone knows a locksmith in the bay area that won't charge me the price of a michelin star dinner just point me in that direction and I'll go find out :)

    this guy's got a fantastic write up for DIY registering the smart key
    amongst other fascinating mods for his tundra

    plus car care nut's experiment boosts my confidence that this will work for my 2024 (I guess just tell the tool that I'm modifying a 2023 instead of 2024?)


    just need to buy a techstream obdii to usb cable to try this now
