I just recently bought a 2010 Chevy Malibu LS but it did not come with a Keyless Fob. i have 2 questions , first question is how do i know if it has a remote start ? 2nd question is what should the GM # be on the back of the Keyless Fob that im going to buy?

 

I responded to your welcome area post , but will also respond here so others may benefit from your question...


Your RPO (Regular Production Option) codes should tell you what options your vehicle has... the label with the codes can be found in your glove box...
A quick trip to your dealer and they should be able to tell you what options you have and what remote you will need...
I think the codes you want to look for are:
AP3 Remote vehicle starter system ( means you have remote start)
AP8 Remote vehicle starter prep package ( means your vehicle is ready but needs a few items added and enabled)
