How to reset a Hormann BiSecur Hand Transmitter

This is a short video demonstrating how to reset a Hormann Bisecur Hand Transmitter into both 40 bit encryption (series 2 mode) and 128 bit 'BiSecur' encryption modes. Other BiSecur hand transmitters in the range may have different battery and button configurations but the process is still the same. Any button can be used to reset the device. Once the device has been reset, the codes on all the buttons have been randomly re-assigned so the transmitter will no longer work with any receivers it has been coded into.
The Hormann Bisecur (series 3) System works on a frequency of 868.3MHz with a 128 bit encryption.

Thanks for this. It was very useful in respect of changing from 128 bit to 40 bit mode. Thank you again.

Same problem, even if I try to reset it to 128bit mode, it's always flashing red.
