Welcome! Auto parts store will usually do this for free. I would go to Amazon and get a OBD 2 adapter so you can use a phone app, connect to the adapter, and clear the codes yourself on demand.
I took a quick look here in Rock Auto's parts catalog, but nothing stood out to me on their site for a replacement. Maybe I overlooked something:
