Ask for the manufacturer for a new one or for the firmware... You are not going to find a legal way to do that...

It is not possible to read program from locked PIC.

Purpose of locking is to stop people of copying code.

Sorry.

It is not possible to read program from locked PIC.

it is actually quite possible to read the code from a protected pic.

in china they called them self break ic they can give you hex code but you have to give one working chip (they will return you with code)
i agree with millwood
i feel very happy to do such work when people saying you can't do -anonymous
