The default code for a Sentry Safe is typically either 1-2-3-4 or 0-0-0-0. The actual combination, however, can vary depending on the model of safe and when it was produced. It is important to note that if you have recently purchased your Sentry Safe, it may come with its own unique factory set code. This will be printed somewhere inside the safe itself. If you cannot find this information, then you should contact Sentry directly as they are able to provide customers with their individualized codes over the phone or by email. It's always best practice to change your default code once you've received your safe in order to ensure maximum security; this way no one else will know what your combination is!
