Lost your keys: what to do first to stay secure
A practical checklist after key loss: entry options, lock replacement or rekeying, and next-step prevention tips.
The first step is understanding where the keys were lost and whether your address can be linked to that keychain. That detail defines urgency.
If risk is high, rekey or replace the lock quickly. Rekeying is often the more cost-effective option when hardware is still in good condition.
Then set up a backup plan: spare key with a trusted person, no identifying tags, and a simple routine to verify key possession.
