MCU2 Swap from Model S to Model X

[ShadowDANCER]

I'm curious if anyone has attempted or knows about swapping an MCU2 from a 2018 Model S into a 2017 Model X with MCU1. I've got a spare MCU2 from a crashed Model S, and I'm wondering if it's feasible to upgrade my Model X with it.

I imagine there might be some software or coding tweaks needed to make the MCU2 recognize its new home in a Model X. Has anyone heard of someone doing this successfully? Or perhaps there's a resource or guide out there that could provide some insights?

It appears that you will need to adjust the internal electronics in order to replace the entire key.

You can find a walkthrough on Tesla's website for replacing the Media Control Unit

Hmm, maybe this is only available in the US and Canada?

Anyway, it seems like a pretty complicated process. Looks like you need a laptop and their Toolbox 3 software.

Hey! I haven’t heard of many people swapping an MCU2 from a Model S into a Model X, but it’s definitely an interesting idea. The hardware might fit, but as you mentioned, there will probably be some software and coding tweaks needed to get the MCU2 working in the Model X. I’d recommend reaching out to a Tesla service center or a third-party specialist to get more details on what’s involved.
