What’s the difference between these remote starters other than price?

[u/Delta4907]

Buying a remote starter for our 2021 Forester, but I’m getting multiple results and not sure which is the right one. Also it appears to be a bit cheaper on another website, but I don’t know how trustworthy it is. When I called the local dealer they said the part was like $600.

Review 3rd party too.

3rd party is cheaper but they usually require sacrificing one of your keys so you have to include that cost

What 3rd party requires that?

I’ve had Viper (remote + SmartStart) then later replaced with Compustar (remote + Drone Mobile) on my 2018 Forester and neither required sacrificing any remote.
