My 2017 RAV4 SE does not have one. Thinking of getting an aftermarket alarm. Will it affect my warranty? Is it even worth it on getting one?
It will not affect your warranty. If it is Toyota's alarm installed by the dealer they will repair it under warranty if it goes kaput.
Aftermarket would have to be taken to the original installer (most likely) if a problem came up.
I have an aftermarket Viper alarm for all five doors, the hood, glass breakage, hard bump, etc. Is it worth it? I felt it was when I lived on the border but I'm not so sure where I live now.....much safer.
