Kimpex backresttrunk

Hey there.. Not sure if this goes here or not.. But I have a Kimpex backrest /trunk that is lockable… But the PO did not have the keys from the Original Owner. I have looked (not real hard) for a set of keys… Was wondering if any of you knows where the data plate-or key number is located… And where I can get a set if keys for this…

Thanks I’m advance.
