Hi there. I'm new to the site. I just bought a sweet 2000 Wrangler Sport. 5spd 6cyl. No problems until last night. Went to crank it and it ran for 2secs or so and then shut down on me. I had the "key" symbol come on, and the odometer showed, "no sup", or "no 5up", (not sure if it was and s, or 5). Anyway the manual seems to suggest that the electronics could no longer match the key code, thus shutting my jeep down. The problem is I only have the one key. Is there a way to reset the the jeep electronics, or to bypass the Sentry system all together? Some of the things I tried:
Disconnected the battery for 5 mins. Reconnected, but no luck.
Ran the diagnostic system, but no luck their either.
Any suggestions? Thanks in advance.
