Lexus / Toyota keyfob replacement

If you have an old Lexus or Toyota with the three button keyfob you are probably well aware that these don’t last as long as the cars do and they probably look like this:

In my redesign I took the opportunity to add some icons to improve usability. Also, since the “battery case door” didn’t do a good job of holding the battery in - I did away with in entirely.

You should split this in half in your slicer of choice and print both halves flat (no support needed) and you should get something like this:

Note that the icons are separated out in the model so that you can color them if you want or just print in one color to “erase” them.

I printed mine with some left over PETG in Black and Clear. I printed mine with 100% infill - it needs to be sturdy!

Instructions for use:

1. Take out the “key” part of your old keyfob by clipping out most of the plastic material to get a “flush” end. I used a pair of wirecutters to do this.  Your mileage way vary but I found these to be a good fit for my broken key ends.  You could also fill any voids with hot glue which is what I did on one of my keys where most of the plastic was off already after repeated crazy gluing
2. Take out the battery pack thingymajig and discard the old battery case. You won’t be needing that anymore. FYI these take CR1616 batteries
3. Use 3X M2 small screws to join the two halves together or just use a dab of glue

I printed one in Petg and another in PLA.  The iconography looked sharper on the PLA but the PETG feels like it will last longer
