2007 Cadillac STS: key fobs..Caddy has a dead battery..car back…

Customer Question
We just bought a 2007...
We just bought a 2007 Cadillac STS with luxury performance package.
This morning we went out to drive the car and get an error message, NO FOBS.
We tried both key fobs; neither of them in proximity to the starter will start the engine when we step on the brake and press the start button.

Nothing listed in the owner's manual about this message will cure our problem.
We're now thinking the Caddy has a dead battery - do you agree that's likely, or is there something else we should try before jump starting the battery? Thanks very much,
Cynthia Saavedra, mother of 15 (and 261 foster children), grandmother of 11.
I need my beautiful car back!

Certain brands of Cell Phone Chargers may produce Electromagnetic Interference (EMI) or Radio Frequency Interference (RFI) that can disrupt the electrical systems within the vehicle. This interference can cause a no start condition with a "No Fobs Detected" message on the DIC. The concerns created by the use of these chargers may be intermittent and random. The concerns can be present with or without the phone connected to the charger. This condition usually occurs when using a non name-brand charger.

if this is not the case ,you most likely have a failed battery.

A no crank, no start condition with a Driver Information Center (DIC) message that displays "No FOB Detected" can be caused by a low battery state of charge (SOC). The Remote Control Door Lock Receiver (RCDLR) will not function if the battery SOC is below 9V.
