The Glass Tube Key is a tiny glass tube that serves as an alternative key ('user key' ) for the RFID ignition lock m-Lock. Please note that the range can be significantly smaller than with the teardrop keys (5-10 mm). The range is also subject to greater tolerances. You can teach a maximum of 3 keys to the m-Lock. To teach additional keys, you absolutely need the 'master key' belonging to each m-Lock.
