Rugged Key Fob Toyota RAV4 3rd Gen(also fits other Toyota models)

I've included a picture of the fob that this model replaces.

Example is printed PETG-CF on Creality K1 using 0.6mm nozzle 0.3mm layer height. Recommend printing PETG or ABS with 0.4mm nozzle, 0.2mm layer height. Print the two main parts of the case inside down and use classic supports. Print the buttons standing on end with supports for the best looking lock symbols.

Uses 4x M2.5x10 countersunk screws and nuts. This is the only hardware you'll need. You'll need to take the original key blade and button assembly(fob) from the OEM key for this to work. It’s a destructive process. Use a utility blade to cut it out. Clamping pressure from the screws keep the blade firmly in place in the new case. This model foregoes the panic button. It also does not have a space for an immobilizer chip, I'm working on adding one. Let me know if you need it and I'll fast-track it. I've been using this model daily printed from PETG for 6 months with no issues.

To assemble, lay the half with buttons outside down, put the buttons in, press your key blade in, install the fob(it’s a snug fit, make sure the nub for the light goes in the hole correctly), put the other half on and install bolts. It may be easier to press in the nuts before assembling everything. They stay in place well. Tighten up the bolts in a cross pattern and you’re good to go! tighten the bolts just until the crack in the middle disappears.

Future updates incoming. The goal is to make it more water resistant in the future.

Share your makes! I'd love to see different color buttons, etc.

UPDATE 04/21/2026 - I've uploaded probably the sloppiest fusion file in existence. It's not pretty, but it's all there. Thought I'd throw it in the mix to make modifications easier since I haven't been able to keep up with it.
