I had fun putting together Howard Hamlin's Duplicated Car Key (used by Saul to open and drive Howard's Jaguar) as seen in Better Call Saul, S06E03 - Rock and Hard Place, and S06 E04 - Hit and Run
The exact model of the RF ID Copier is slightly different, so the electronic components don't all 100% match up, but pretty close.

As I mentioned, the model I picked up isn't exact, but I am not sure if there is a way of knowing what is exact. There are some modifications that need to be done.
1. Remove the shell from the board.
2. Carefully superglue the rubber buttons to the front of the board. This is a little more tricky than it sounds because you don't want glue on the buttons, and there are also raised and depressed areas on the back of the button pad. You only want glue on the raised areas, which are hard to see.
3 . Remove the video screen by detaching the cable on the front of the board.
4. Unsolder the Speaker from the board.
5. Desolder the Speaker, Square Copper Loop, two large capacitors, and the two battery springs from the board.
6. Using red electrical tape, tape the leads to the speaker. Solder the speaker to the position where you desoldered the Square Cooper loop. Hot glue the speaker to the speaker to the upper center of the back of the board, with the leads in the 8 o'clock position.
7. Carefully use a pair of flat pliers to "crush" the square copper loop. It is a stranded wire altogether. Take your time with this, but you just want to make it a little ugly and misshapen. There are two thin leads coming off one corner of the loop. Look at the reference and position them to the top inside corner. Leave them hanging for now. Use a tiny bit of stranded copper wire to wrap around the loop through the left screw-hole of the board. Solder this wire so it can't come back apart, but leave it slightly loose so the loop will flop (you can see this happening as Saul is walking to Howard's car in S06E04).
8. With a dremel, cut small grooves in the bottom of the board about 1/8" below where you desoldered the battery springs. Reinsert these springs into these grooves and superglue in place.
9. Glue the battery box face-down (it is not functional) onto the back of the board. Solder the red lead to the battery spring on the right, cutting it to the appropriate length. Solder the black lead to the battery spring on the left, not cutting it, but bending up the excess.
10. Wrap the thin leads from the copper loop around the red lead of the battery box. Do so in a sloppy manner.
11. Take one of the keyrings off one of the fobs that came with the RFID copier. Allow the magnet of the speaker to hold it in place.
12. Clip the ringer binder through the screw hole on the opposite side to the copper loop.
Again, this is not perfect, but pretty darn close.
