Does power wire (2awg) connected to battery produce a radio frequency that interrupts fobs?

[cpassmore1]

I've been experiencing odd behavior with the way car acts with key fobs after stopping (won't recognize lock signal unless next to car). This ONLY happens after stopping, not if it's in garage/parking lot and sitting for 5-10 minutes. Tech said he talked to their contact at Ford engineering (seems extreme… but whatever) and they're saying that wires connected to the battery can generate radio blocking frequencies that 'jam' fobs.

Tech unhooked battery wire and isn't experiencing any issues with locking/unlocking car.

I'm not sure I believe this… but has anyone else experienced this? Everything is grounded back to the battery.

If that were the case every car with an aftermarket audio system or anything else hooked to the battery would have issues with the key fob. They do not.
