Why Choose the ABB MKEY Manual Release Key?
The ABB MKEY Manual Release Key (2TLA050040R0400) is a dedicated manual unlocking accessory for ABB MKey8Z safety locking switches. It is designed to operate the manual release mechanism provided on compatible MKey8Z guard-locking switches, allowing authorised personnel to mechanically release the locking mechanism when manual unlocking is required.
ABB identifies this accessory as the MKey8Z Manual Release and specifies a stainless-steel release bit. It is distinct from the normal MKey actuator keys used to indicate the position of a machine guard: its purpose is specifically to operate the switch's manual release point rather than to function as the guard actuator.
The key is a compact, passive mechanical accessory requiring no electrical connection or power supply. ABB lists the accessory with an IP67 degree of protection, making it suitable for maintenance and service use with compatible MKey equipment in demanding industrial machine-safety environments.

Dedicated Manual Release for ABB MKey8Z Safety Switches
Guard-locking safety switches are designed to keep a machine guard secured according to the requirements of the safety and control system. Compatible MKey8Z switches incorporate manual release points that allow the locking mechanism to be mechanically operated when an authorised manual release is required. ABB 2TLA050040R0400 provides the dedicated tool for this function.
The manual release key should not be confused with an MKey actuator or maintenance lockout actuator. It does not replace the actuator installed on the guard and does not itself provide a safety switching function. Instead, it is a service and manual-release accessory intended for controlled use with the compatible MKey8Z release mechanism.
Typical Applications
- Manual release of ABB MKey8Z safety locking switches.
- Industrial machine maintenance and servicing.
- Guard-locking system commissioning.
- Machine safety switch maintenance toolkits.
- Automated production and assembly machinery.
- Packaging and processing equipment.
- Replacement of an existing MKey8Z manual release key.
