I removed the C pillar trim because i'm getting my windows tinted this week (20% front and back) and under the passenger side C pillar trim I found a long thin wire that seems to be the antenna for the keyless entry/remote. If that's the antenna, how can I make it ''bigger'' to get a better remote range ? And I think I read somewhere that the length of the wire is the frequency but i'm not sure anymore about that..
