can someone help me i noticed when
 

my spark plugs were being put on a sticker says auto starter installed now i have a antenna in my car above my mirrior that comes down the windshild a little bit if i have this where would it be ,and how could i get a keypad for it?:confused:

The unit would most likely be under the dash. Take a look under and see if there is a box(usually black) that doesn't look factory. As far as getting a remote it might be difficult to get one that would work.

there is a small box on the antenna the antenna has a point at the end i hvae no clue what it is for but tom i'll look under my dash ty

Is there a brand name on the antenna?
