If you want to DIY this, 9651 has a spring on the board , first thing is the cover closing it?
Second if you believe you have factory reset it's means you have the default engineer code? Manuals are widely available on internet of course
Oh change the battery probably rattling by now
What area or part of country are you in?
The 9651 doesn't need allot to set it up for DIY use if your competent enough
Others also who post in here will suggest that ... ... But of course you might just "mash" it up as I say
