Greetings...
Fell down the rabbit hole on recent news about thefts of our vehicles using the vehicle's key fob code transmission.
Ordered a faraday case for my fobs to use when on trips to the big city...
However, I'm looking at my emergency key and instruction for it's use if the fob battery fails.
Now I'm wondering, can I just remove the fob battery and use the emergency process to access and start the vehicle when in sketchy country? Without the battery the fob won't be transmitting a signal to repeat/record. The hard key can get me into the vehicle. I can lock up the vehicle using the armrest button when exiting.
So I guess my question is, does anyone know how long the fob will keep it's emergency (pressing dash button with fob) start capability after the fob battery dies/is removed?
How long does the fob chip retain it's coding function without the fob battery?
