Description
Overview:
The Activation Key is a Genuine Stihl OEM part used to enable power on selected Stihl cordless tools. Built from a durable, high-visibility polymer with a moulded grip, it is designed for repeated insertion and removal without deforming. When inserted, the key completes the tool's internal safety circuit so the machine can run; when removed, it provides a simple lock-out to help prevent unintended starting and unauthorised use. It is suitable for Stihl AI Line equipment, including the HSA 45 hedge trimmer and BGA 45 blower, and is the correct replacement if your original key has been lost or damaged. Manufactured to Stihl's specifications (MPN 45114057400), it offers reliable, no-fuss operation and keeps your cordless hedge trimmer, blower, or light-duty trimmer ready for work.
