How Do I Change the Batteries on My Safe?

Need Help with Your Digital Lock?

Most digital lock problems are related to low, dead or Non-Alkaline batteries. For most SentrySafe models, we recommend the following:

• Refrain from using rechargeable or Non-Alkaline batteries.
• Use quality name brand batteries.
• All batteries have expiration dates on them. Ensure those dates are as close to 10 years out from current year as possible.
• When changing batteries do not mix brands (i.e. all 4 batteries should be Duracell) or mix old batteries with new batteries.
