The video shows us how to replace the battery of a Fiat key. Specifically, the key shown in the photo is from a Fiat Freemont, but the tutorial is also valid for Jeep keys that have a similar appearance. First, we extract the emergency key, which is the blade of the mechanical key, by pulling it outward while pushing the appropriate button.
Turn the key and NOTHING happens with the starter. The display reads "Key Not Detected". Turn the key around, use the other key, wiggle the key in the ignition nothing. Thirty minutes later car works great! Works great with both keys. So now it is working great. Seems weird to take it to the dealer.
