The Bosch Default Unlock Key (CM255) is a specialized, single-use security tool designed to reset Bosch intrusion alarm control panels in cases where the installer lockout has been activated. This key provides an essential recovery function, enabling service technicians and security professionals to restore panel access without full system disassembly or replacement.
Specifically compatible with Bosch Solution 6000, 64, and 16 Plus alarm systems, this default unlock key performs targeted or complete default resets depending on the panel type. On Solution 6000 systems, it resets the installer code only, while for Solution 64/16 Plus panels, it performs a complete factory default reset.
The CM255 key is a "one-time-use" item, making it a secure and tamper-proof method of restoring access to locked-out panels. This is an essential component for authorized Bosch technicians and alarm service providers.
