B&D has introduced a new range of garage door openers.
They have increased security by going to 128 BIT encryption from the previous 64 BIT system used in the B&D TRI-TRAN, TRI-TRAN MINI & TRI-TRAN VERSION 2. The new system is compatible with the old but old remotes will not code to the new equipment.
The older RED REMOTES with BLACK buttons have been replaced with the B&D TB5 TRI-TRAN with GREY buttons. Also introduced is the B&D TB6 TRI-TRAN PREMIUM remote in RED & CHROME + BLACK & CHROME.
No change in the CODING instructions - https://www.dropbox.com/s/e9l9st23imespja/B%26D%20TRI-TRAN%20-%2030-10-2015.pdf?dl=0
