TIL most alarm panels have a hidden master code that resets everything

I was swapping out an old Honeywell panel last week and stumbled on this in the install manual - the factory default master code works even if the customer changed theirs. Saved me from pulling new wire on a panel that was locked out. Has anyone else used this trick on a stubborn system?

Yeah that saved my ass on a Vista panel last month when the homeowner forgot their code completely.

lol reminds me of the time I tried resetting a panel and accidentally set off the alarm at 2am. Neighbors were not impressed.
