2009 Trouble with wireless ignition node
My friend has a 2009 RAM 2500 with a soft touch pear-shaped ignition key. Has a hidden-typical key in buy of his Integrated Ignition key.
Recently it was brought to my attention that the following happened in chronological order.
- Early Summer, vehicle sat for 2 weeks unused.
- First 3 start attempts, key/fob 1 failed to be recognized. Pull Negative battery cable, wait 2 minutes. Re-attach neg. battery cable, vehicle starts on first attempt.
- Next day key/fob 1 Remote keyless Entry (RKE) functions fail to unlock doors/panic. Still starts engine.
- unknown time gap.
- Key-in ignition sense fails, cluster claims key is always in actche.a week or 2 pass, key/fob 2 RKE functions fail, still starts engine.
- Take to stealership, dealer claims to have replaced the 2032 clock batteries in fobs
- Today, noticed that with or with out key present, engine starts with finger in key-hole.
- Today, disassemble key/fob 2, clean all contact surface with isopropyl alcohol, Bend up 2032 battery terminals. RKE still fails.
- Today, after hours of searching the internet and autozone for diagrams, pulled 16pin wire connector from Wireless Ignition node(WIN)(Key switch). Chime still 'dings' claiming key-in ignition, while keyswitch is still unplugged.
- Plug 16pin plug back into Wireless Ignition Node, Chime changes to a stuttered chime, stops.
- Close and reopen drivers door, key-in ignition chime still 'dings (w/o key).
- No longer starts with finger in keyhole. Claims invalid key.
I think that once the key is integrated and authenticated, it holds onto the digital signature of the key until it is removed. That's why I believe I could still start the key with my finger and the key was nowhere in sight.
If this still starts after re-authenticating key, I will make a video.
