Can I just say how much I LOVE this forum?!?
I just had my new subwoofer/amp "professionally" installed and I get my jeep back with the push button start and keyless entry not working. So the installer tells me those things often go out on vehicles and they probably need to be replaced. Really? Cause they were both working just fine when I dropped my car off!
Anyways, followed the instructions above and the blue wire was connected but it seemed loose. Took the piece off where the wire plugs in and saw one of the pins was completely bent down. Straightened it out, plugged it back in and whaddayaknow everything is working again!
Thank you for this fix!!!!! You guys are awesome!
