One Fob, two Teslas?

[dogldogl]

Does anyone know if it possible for two Teslas (Model X, specifically) to be programmed (by Tesla, obviously) to respond to a single fob?

Does the fob modulate a "private/public key" of the car, or is the inverse true?

I'm pretty sure the FOB itself can only be associated with one car at a time.

A slightly different question;
Does anyone have experience attempting to share a single fob amongst two or more Model X vehicles?

Related: Is any portion of the pairing process for fob/car visible to the folks on the forum with dev access to the MCU, who might shed light on this?

(I'm eager to better understand the fob/car handshake [pairing] mechanics).

Sharing of fobs between cars would be nice for those with multiple Teslas. Another thing Tesla could implement would be different colored fobs to match the color of the cars.

They are trying to make things simple. Multi coloured fob would be cool but not going to happen. I got a silver case to match our silver X

This.

Further, I’m looking forward to (hopefully) using the proximity of my phone (Bluetooth) to passively unlock and enable keyless driving on the Model X, so that I can carry zero fobs in future.

We have a red X 100D and a blue X 100D.

Initially thought it would be useful to have a single key fob for both vehicles.

But... If you press one of the key fobs - wouldn't it affect both vehicles, when they're nearby? I've gotten used to carrying both key fobs on a key ring in my pocket - and don't think it's really that big of an issue to carry two key fobs.

As for telling them apart, we bought colored key fob colors, which match the color of each vehicle - so we can easily tell the key fobs apart.

Oh I'd love to see the summon videos of both cars responding to a single key fob command...

Gosh, I hope this is not possible. Risk of abuse making our cars susceptible
