Unsolicited advice on duplicate key fobs (2023 F150 Lightning Lariat)

[FLSpartan04]

Hmm. Maybe you got a dud? I have done with with multiple AliExpress keys without issue. I also helped another forum member with his (making a 3d printed key card) and I don’t think he had any issues with programming his. I’ve never done a return to AliExpress, but you could try. I’d probably just order another with how cheap they are. Oh, did you make sure to get the right frequency? You can program the wrong frequency, and it will work in your cup holder spot to start the vehicle, but otherwise it will not. See if it starts the vehicle in the cup holder. If it does, this is likely the case. I did this, as well on accident, and I keep that as a backup hidden in the truck. I figure worst case if I lose my key, I can unlock the truck, find this fob, put it in the cup holder spot, and start the truck to get back home. I like this one being in there, because if it is found, it would seem like it is non functional any way. I also husked the pcb from the original fob case and put it in a 3d printed case, so it doesn’t look like a fob if found.

That’s what I’m thinking but it helps to have confirmation! I was aiming to do that 3d printed mod as well so this is a bit of a bummer but happy to try again. Aliexpress returns are a little tricky but it’s no problem haha. I’m fairly certain I got the right spec one but do you have a specific link and model you could send me? I’ll give it another go and see what happens!

Solid idea though, I like that. I did try to start it removing the two functional away from the car with this one in the spot but same thing.. no go. It’s just odd it gives me the full confirmation, I did it successfully a handful of times last evening and same thing. Time to try again!

I put all the details into my thingiverse upload. Make sure you get the 315 mhz frequency.

Thats the exact one I did following your directions so maybe it was just a dud. Willing to give it another shot though!

Thank you for being so active and developing this kind of stuff along, for real though its killer.

Oh cool! Mine has been no issues so far, so likely you got a dud, then. I love not having to carry a key. I think I’d have even done this if I had PAAK after reading the horror stories of it all of a sudden not working and the passcode not working either. Once you get it programmed, if you run into any other issues, let me know!
