What are the main disadvantages of physical keys that drive organizations toward keyless systems?
Keys are a logistical nightmare at scale: they get lost, copied, shared, and there's no audit trail of who used them.
The five core problems:
| Problem (DE) | Problem (EN) | Real-world impact |
|---|---|---|
| Schlüsselverlust | Key loss | A single lost master key may force replacing every lock it opens |
| Kosten beim Austausch der Schliessanlage | Cost of replacing the locking system | Re-keying a corporate building can run into 5–6 figures |
| Weitergeben von Schlüsseln | Sharing keys | "I'll lend you my key for the weekend" — no audit, no expiry |
| Illegale Schlüsselkopieren | Illegal duplication | Most key blanks can be copied at any hardware store, even "do-not-duplicate" stamps are advisory only |
| Kein Überblick im Schlüsselmanagement | No visibility into who holds what | Without a registry, you don't know who has access to what — until something is stolen |
Why this drives the move to electronic systems:
Each problem above maps to a feature of electronic access control:
- Lost key → revoke the credential, no hardware change
- Sharing → tied to identity, not a transferable object
- Copying → cryptographic credentials can't be photocopied
- Audit → every door event logged with timestamp and user
Tip: This is the same shift from passwords-on-paper to identity-managed authentication — physical keys are a "shared secret" with all the same problems we have in IT auth.
