Possible to add remote start to my 2026 2500hd custom?

I got this truck back in March and love almost everything about it, the only thing it's lacking is remote start. I live in a state that turns into a glacier for half the year and the older I get the less I want to deal with the cold.

I called the dealer and they quoted $850 to install it, plus there's about a 6 month backorder. Is it possible to add remote start while keeping the factory key fob without paying those insane dealer prices?

[I found this kit](https://www.shopchevyparts.com/chevrolet/2026/silverado-2500-hd/electronics/85768274-silverado-2500-remote-start-upgrade-without-power-lock-lift-tailgate-button-remotes-p-92341636.html?sort=2a) that still needs dealer programming but is a little more reasonable. I've seen other aftermarket systems and I just don't want an additional fob I have to carry around.
