Key fob chip transplant?

I'm in something of a bind. My key fob is pretty torn up, and the lock button has been ripped clean off, with the PCB pads exposed. I could try to "press" the button by sending a current through the right pad, but I don't want to break anything. Since I can't make a lock input, I can't do the "chicken dance" to program a new fob. I've been trying to clone the chip with a Flipper Zero to no avail.

Would I be able to get a new key and just swap the chip into that? It looks like I can pull the chip straight out of the old case as is. I'm pretty sure it's that black plasticky thing near the end of the case, so if there's nothing on the PCB that needs to be programmed it might work.

Is that even possible?
