Key buzzer to chime

This appears to give some more input on the module I linked above. Door Buzzer too quiet? - Ford Bronco Forum

Based on a quick read of the above, it looks like it might have some potential.

Provided that it is actually a chime and not a buzzer. Funny how many hits I got when I googled "chime" that actually related to "buzzer".

Thanks for all the information, looks like a good place to start. I did fine this one which is for a Viper. The pins look similar to the one used back then, but haven't found the schematic yet to verify.
