Hello everyone. Been reading the board for months before and after purchasing my 2008 G6 GT sedan. I have the remote for the key-less entry until recently the only remote i have broke. So my question is should i have the dealer add the remote start and two new remotes for about 350-400. Or should i just install a aftermarket remote start with alarm system. Also has anyone ever put in their own system. I great at electronic but never installed a complete alarm system with remote start before. The installations directions seem simple just wasn't sure.
