Digital vs Physical Access Control – What's Best for Your Business?
The choice between digital access control and physical keys isn't just about technology – it's about security, economics, and compliance.
With new legal requirements like CER and NIS2, access documentation has become critical for many businesses. In this guide, we compare the two methods across all important parameters.
TL;DR – Quick Comparison
| Parameter | Physical Keys | Digital Access Control |
|---|---|---|
| Security | Can be copied | Cryptographically protected |
| Traceability | None | Audit trail |
| Revocation | Requires rekeying | From the dashboard |
| Time-limited access | Not possible | Yes, down to minutes |
| CER/NIS2 compliance | No | Yes |
| Operating costs | Ongoing (keys, locks) | Lower over time |
| Technician onboarding | Hours/days | Seconds |
Security
Physical Keys
- Can be copied – A key can be copied at any locksmith
- No control – You don't know who has copies
- Lost keys – Requires rekeying of all affected locks
- No 2FA – Anyone with the key has access
Digital Access Control
- Cryptographically secured – Keys cannot be copied
- Personally tied – One key per person
- Revocation from the dashboard – It takes effect when the lock system receives the change. For a phone key, typically within about 30 seconds.
- MitID/2FA – Require extra verification for critical zones
Traceability and Documentation
Physical Keys
- No automatic log
- You don't know who was where and when
- Manual documentation – if at all
- Impossible to meet CER/NIS2 requirements
Digital Access Control
- Automatic access log with timestamp, person, and location
- Exportable reports for audits and inspections
- Traceability – See who opened which doors, as reported by the lock system
- Compliance-ready – Meets CER, NIS2, and energy law automatically
Economics and Operations
Physical Keys – Hidden Costs
| Expense | Example |
|---|---|
| Key copy for new employee | $7-30 |
| Rekeying for lost key | $75-300 per lock |
| Coordination time | Hours per month |
| Key cabinets and administration | Ongoing |
| Lack of traceability | Compliance risk |
Digital Access Control – Predictable Costs
| Expense | Example |
|---|---|
| Subscription per lock | Fixed monthly price |
| Onboarding | Free via app |
| Revocation | Free, from the dashboard |
| Administration | Minimal via dashboard |
| Compliance reports | Included |
ROI: Most businesses save 30-50% on key-related costs in the first year.
Flexibility
Physical Keys
- Cannot be time-limited
- Requires physical handover
- Difficult to handle temps and external contractors
- No automatic expiration
Digital Access Control
- Precise time windows – e.g., weekdays only 8am-4pm
- Send key via SMS/email – recipient gets access once they activate the link
- Automatic expiration – key expires automatically
- Revocation from the dashboard – if the collaboration ends
Compliance (CER, NIS2, Energy Law)
New legislation requires:
- Documentation of who has access to critical infrastructure
- Traceability and audit trail
- Role-based access control
- Contingency plans and risk assessment
Can Physical Keys Meet the Requirements?
No. Physical keys provide no traceability and no automatic documentation. Compliance requires extensive manual registration.
Can Digital Access Control Meet the Requirements?
Yes. SnapKey automatically generates:
- Access log with timestamps and personal data
- Exportable audit reports
- Role-based access control
- Approval workflows for critical access
When Do Physical Keys Still Make Sense?
Physical keys may still be relevant for:
- Private homes without compliance requirements
- Very small organizations with few locks and people
- Legacy installations where upgrading isn't possible
For businesses with multiple locations, external partners, or compliance requirements, digital access control is almost always the best solution.
