I found that ordering a replacement key directly from SentrySafe was the most straightforward and safe option. Here’s what I did:
- Located the serial number on my safe.
- Visited the official SentrySafe website or called their customer service.
- Provided the serial number and proof of purchase or ownership.
- Paid a small fee for the replacement key.
- Waited for the key to arrive, which usually took a few days.

Having all these ready saved me time and hassle.
Tips for Avoiding Future Lost Key Issues
After this experience, I took steps to avoid losing my key again:
