I've noticed when I leave the Bluetooth OBD-II dongle i use with the torque app connected to my car that the keyless entry remote range is effectively cut to a few feet from the car.

anyone else notice this phenomena with other OBD-II devices or care to speculate on a cause?

 

I've never noticed that and I leave my adapter plugged in all the time.

 

I've never noticed that

 

No idea then. Can't be radio interference as the remote works in the 400mhz range and bluetooth is 2.4ghz

 

2400/400=6
It can be harmonics from some cheap BT module inside the OBD dongle.

 

My keyless range is like 2-3 feet at all times...I just assumed this was normal. I thought it was pitiful, but normal. And, I have a brand new battery in my remote. Weird.
