The 12 v tested fine.
Both my husband's and my fobs seem to get disconnected of something from the car. If I walk up to it and push the button it works and then works normally from the expected range for some amount of time.
A day or two later I can't unlock it until I walk right up and push the button. We replaced the battery in one of the dogs and the same thing. This just started happening a couple weeks ago, was fine for months after we got it (used earlier this year)
