I have an '09 Challenger SRT8, when I got it the lock and unlock was iffy at best, and I'd have to click it a couple times to get it to do either. It progressively got worse to where it would rarely unlock, then started giving me a "Damaged Key" message. So, it would rarely unlock and the PTS didn't work at all. Come today, I buy a new OEM key for it, and I get the same message. Suggestions? I don't want to pay $140 to the dealer to find out I need to pay another $300 for a WIN or PEM module. Key guy told me he guessed it was an onboard computer problem but I want to cover all my bases. Thanks!!
