Hello and welcome! Please stop by the member introductions section and tell us some information about your car (PS we love pics of impalas even more).
the device you're looking for is something like this (i used this one 8 years ago on my 2010 and had no issues with the unit): https://www.walmart.com/ip/SCOSCHE-G...Chime/26978037
there may be a volume switch on the unit, i had set mine to high and it was VERY clearly heard...annoyingly loud when at low volumes at times. but at least i didn't forget my keys in the ignition.
