Help needed with programming for DSC PC2530

["Brian O" <briano1812@xxxxxxxxxxxx>]

Hi Everyone,
   I hope this is the correct place to post this.  I have an old PC2530
alarm system that was monitored by ADT. I discontinued my service to them,
but now that I want to start service with someone else, they tell me I need
the lockout code that ADT programmed into my alarm so they can program the
alarm. Of course ADT isn't giving this out. Is there a way to circumvent
this lockout code?  I have a degree in electronic technology so doing
something to the circuit (grounding reset to the EPROM etc) to be able to
program it is not a problem. Problem lies in that I don't know how bypass
this lockout code or how to program it if I DO get it bypassed. I'm pretty
new to the ins and outs of alarm system other than the basics so any help
would be appreciated. Thanks.
B.
