Title: FOB Battery Dead
Post by: Auggie on March 07, 2016, 06:18:25 PM
FYI. I have a 2015 SHO and I thought that I would find out how to start the car if the FOB battery was dead because my wife drives the car 90% of the time. I read the owners manual and removed the key from the fob. It then said to insert the key in the slot on the steering column or in the slot in the center council. I do not have either slot so I called Ford and they don't have a clue. It gets cold here in MN so this would be good to know. Does anyone or has anyone ever had to do this ?? If so could you answer this question and get back to me. I tried to post this question on the "SHO Form" but for some reason I am no longer able to post or reply ??

Good advice below... Better yet, the cost of a battery a year is worth the grief factor if it dies... BTW my SHO is a DD and after about 18 months I got some erratic behavior from the fob which a battery change fixed.

This has been discussed in the past.

OK, I think I have got this figured out. The key in the FOB is only used to open the car door. Our car has the numbers on the door but if I forget the code I can always use the FOB key. And like you all said is to insert the FOB in the slot in the center council. Here's how I think this works? As you all know when a battery doesn't have enough voltage to operate the doors or start the engine the battery voltage is not at "0". SO when you put the FOB in the slot there must be a sensor there that will read low voltage and allow a person to step on the brake and push the button and start the engine. Thanks to you guys for your posts and I like the idea of just changing the battery once a year for good insurance.

Perfect time to test it. Remove battery from fob and see if car starts. Would be good info

Ok, I did what Dx suggested. I removed the battery and slid the FOB into the slot in the center council, pressed on the brake and pushed the start button, nothing? I removed the FOB and tried it again but this time I slid the FOB into the slot with greater force. The FOB went in deeper and I could feel something give. I stepped on the brake, pushed the start button and the engine fired right up !! There must be a switch in the slot that activates the starting system which would be a whole lot smarter then a low voltage sensor just in case the FOB battery was in fact at zero voltage. So disregard the BS that I posted in post #7.
