Hi.

The only way to open a sentry safe is by using a registered combo, or by contacting Sentry. There is no other simple and non destructive way to open a Sentry.

See here: Sentry respects strong security standards. There is no simple way of hacking a safe if you loos.

Sentry...thank you...someone has found my safe...and after looking in my history on my computer... i noticed they were trying to get advise on how to change combo or get into system by over-ride through your web site.... i was worried about this person finding out combo, until i noticed your strict confindential policy. the last safe i bought they tried a screw driver and broke knob and bashed key pad trying to get in... they couldn't, needless to say we replaced it with a heavier model, but they are trying to figure out another way, so they thought of your web site,( i discovered by researching my google history)... thank goodness you dont give them advise on how to overide or get into my safe without distroying it.
