I'm pretty sure this is what's happening to mine unless anyone has any ideas.

Started yesterday (Friday), when the key fob didn't unlock the car. Manually unlocked it and carried on thinking 'I need to replace those batteries..' Later in the day try to start, cranks, dies.. try again, cranks, dies.. In my head I'm thinking ' what's going on here'.. try a third time and nothing..

Battery is new and charged, terminals clean, replaced batteries in fob. Towed it home and checked the RCM. It looked OK, but I hit it with some solder anyway just in case. Nothing.

I'm not sure if it's taking out the RCM or disconnecting the battery, but, when I hook it all back up, it will crank exactly 2 times again.

Fob's still don't work even though everything else does.. except the starting part of course

I bought extended warranty with it so I guess I'll see what happens Monday if no one else has any ideas.
