Issue: Reduced Infokey radio range
 

Hi
I have i2, bought is used.
The range in which infokey works is reduced to just about one foot.
I tried both infokeys, with different batteries.
I did check the antenna under the rubberized console cover - if I remove it then it won't wake up at all.
Tried to replace antenna with a wire of increased length - no changes.
Any suggestions?

I know you tried with different batteries, but to be clear, you tried with brand new batteries?

Batteries were new.
Another battery was extracted from working infokey from another Segway.

I’ve bought many new batteries from stores and internet and about 1/2 of them were no good. I built a tester (a 3v flashlight bulb with wires soldered to ends) and test each battery. Clearly there is a difference, I think if you search posts for info you can find the brand that is best. No trouble since then.

I took 2 AA batteries, they made 3.7v together. Powered infokey from them - no change.

Radio Board needs replacement. It has to be programmed by Segway to the SN of the unit.
