Sanity Check ? Making Changes to a Key Field of a Rather Large Parent Table

Thanks for your quick response, I was out of the office and didn't see this until today.  I'm definitely not against changing the key field to the record ID, but how can I do this and make sure the only thing that displays is the Customer Name on each form?  I also need it to link to the record from the customer name.

I know that I can update the record picker to show only the club name field, but in my test version after I save it, it displays the record ID.
