Key Management Systems for Multiple Properties

1. Master Key System

Re-key all your locks to a "Landlord Master" system.

• Tenant Key: Opens only their unit.
• Master Key: Opens all units.
• Pros: You only carry one key.
• Cons: If you lose the master, you have to re-key every single unit.

2. Key Codes (Smart Locks)

The modern solution.

• Give each tenant a unique code.
• You have a master code.
• Pros: No physical keys to lose. Instant re-keying.
• Cons: Batteries die.

3. Key Tracking Box

If you use physical keys, use a lockable key cabinet.

• Tag keys with a code (e.g., "Unit 101"), NOT the address (in case the box is stolen).
• Use a logbook to sign keys in and out to contractors.

Conclusion

Access control is a major security liability. Treat keys like cash.
