Hi,
I can't close the door/lid of the battery on my Garmin sensor. The battery is flush but it never shuts. I line it up correctly but if I remove pressure at all, it pops back. And every single time I slide it into the locked position, one side pops but. Two people have tried many, many times and it just will not close.
I did this to replace the battery because my sensor was no longer being detected. But it seems that failing to lock the battery in place is keeping the new battery from being detected.
