Bose PM8500 5 digit pin

I have a Bose PM8500 I am currently locked out of it. I am a maintenance supervisor at a mall and a store closed and left behind everything for their sound system in their store anyways it just so happens that it’s the same amp we use for the mall and ours took a crap. However, the one I took out of the store is locked is there a way around it?

Is anybody willing or able to help with a Bose Pm8500 5 digit code. I’m locked out of mine and can’t seem to find any info
