FOB Again
Well I had my first experience with FOB "hell" tonight. I went out to start the 06 and got nothing but a "click." This happened numerous times. I naturally thought battery, so I jumped it and off we went. I had a thought that maybe I had left something on. We reached our destination so I shut it down then started it right back up. OK I thought, not problem. I come back out 45 minutes later and guess what? "Click"
I noticed that it said "No FOB detected." I put it in the glove box slot and click again. We get jumped and it started again after several tries. I head immediately to AutoZone and have them test the battery. Their tested shows the battery is good. So I buy a battery for the FOB. Click again. This time it won't even let me in the car or unlock the doors. Into the slot we go again to start and head home.
I get the other FOB and it works fine. Now the original FOB does nothing, even after another new battery and trying to reset it as per the instuctions in the manual. I am frustrated now.
Any ideas? I have read the other FOB threads looking for ideas. Two days ago there was no problem at all.
Who is the best source for a new FOB?

From the many posts in this forum on the subject, the car battery can test good at any given time, yet be on its last legs and about ready to go out completely.
I'd try to do more to find out what shape the battery is really in.

with both of the above. It is likely not the fob. If the battery is the original one from 2006, then that's most likely the culprit. The fact that you were able to have things work when you jumped the car tells the story. You got a good solid three or four years out of your battery, call it good and just get a new one.

Since the other FOB works fine, are you 100% sure you installed the new FOB battery in the correct direction? Others have installed their batteries backwards by mistake. It almost sounds as if the FOB battery was starting to die on you and then when you replaced the battery it died altogether. I would open the second FOB, look how the battery is installed then check the first one. If the battery is installed backwards, reverse it and try again.

Have you tried the good and bad FOB after you got home? Maybe in the morning try the bad one, then if it still don't work and the good one does then it has to be the FOB. May swap the batt. between the two and see if the problem follows the old batt. or if the original FOB works with the new (used) batt.. Could be the new batt. you put in the FOB was bad or as stated put in backwards.

Reminds me of the time years ago when my '65 Ford wouldn't turn over. So, of course I replaced the starter. But that wasn't the problem. Long-story-short, not only had the battery discharged but one of the cables had serious hidden corrosion.
I haven't heard of any C6 with a battery cable corrosion problem. Probably still too new. But it's worth a quick check before you replace the battery.

1. Just change the battery.
2. Get a lawyer and sue.

While we're at it, just get rid of the windows too - don't have to worry about things like indexing.
