battery keeps going dead but only at home. the dealership blames the key fob.
dealership says that continuous proximity of the fob to the vehicle engages the LED illumination of the door handle. Has anyone encountered this problem? Is there a way to turn off this feature?
Try storing the key fob further away from the vehicle to see if that is indeed the problem.
Sounds like something else is going on, the LED itself wouldn't pull enough power to drain a battery. Either the battery is faulty or something else is draining the battery. Like a bad ground, relay, another light on, etc. Have the dealership inspect it more thoroughly.
Tom's right, LED's that size will run for weeks on a car battery, I would suggest try someone else, and you don't necessarily need the dealer to look at it, there are good independent shops out there, some even specialize in your make of vehicle.
It is possible that the key fob being too close to the car is causing one of the computers or modules to stay awake. This can run down the battery. A similar thing happens to C6 Corvettes if the FOB is too close to the car. The module stays awake and discharges the battery over a couple of days. To test this put the fob further away from the vehicle or store it in a metal kitchen cook pot with a metal lid on it. Putting the FOB in a metal pot with a metal lid will keep it from communicating with the vehicle.
You could also remove the battery from the FOB and try that as a test.
