No key fob???
Have an 05 corvette base model. When i sit in car displays no fob while i have key fob right there i hit the start button about 20 times and car eventually turns of after a minute or 2 very annoying does this everytime.
Changed the batteries on the key fob still same problem. Fob works fine to unlock and lock doors at a great distance so i dont think the key fob is the issue!

Also, strong electronic signals from other devices that are near the car.

Since you've ruled out a weak fob battery your RCDLR module may be dying.
Have you tried putting the fob into the slot in the glove compartment when this is happening? Can you open the passenger side door by pressing the door handle (i.e. without pressing any buttons on the fob itself)? What about the rear hatch?
If some antennas work but others don't, you may have one or more bad antennas. If none of these antenna locations works, the only common point of failure is the RCDLR module itself.
Try them all and let us know which ones work and which ones do not.

Check your car battery - this may be one of the early signs that the battery is getting weak. Twice my battery has died and while the car would always start, early on I would have trouble with fob recognition and then getting some weird read outs on DIC.

Pushing buttons on the FOB causes it to send high powered signals to the car where you have large antennas and a powerful receiver. The passive recognition signals require the FOB to receive small signals with the tiny antenna in the FOB. That is why you can unlock the doors from 100 feet pushing buttons but have to be within 3 feet for them to unlock while trying to open the door.
When the passive system isn't working there can be many causes because it is marginal to begin with. Primary causes, IMHO, are battery in the FOB and battery in the car. Both will cause lower signal levels of the transmitter or receiver. Sometimes you get a brand new FOB battery and the new battery is as dead as the old one. Try another. They're inexpensive. Next get a battery tender and make sure the car battery is full charged. If either of these suggestions solves the problem you're done.
If not does it work the same with both FOBs or only one. That would indicate a bad FOB. Does the slot in the glove compartment solve the issue? That would indicate an interference or car receiver issue if both FOBs react the same.

A weak or dying car battery, a weak or dying fob battery or radio frequency (RF) interference from aftermarket devices such as 2-way radios, power inverters, cellular phone chargers, computers, etc. may cause a system malfunction. High RF traffic areas, such as gas stations which use pay-at-the-pump RF transponders, may also cause interference that could lead to a malfunction.
