Help needed sourcing manual release key - Chamberlain HC300 - pb3000 - 30-07-2025
Hi Everyone,
I've recently moved house. My new residence has a Chamberlain HC300 electric gate opener.
The gates are currently opening and closing perfectly. The thought has entered my mind that should there be a power or motor failure when the gates are closed, then I may well regret the fact that I never learned climbing as a skill
Unfortunately the previous house owner cannot find the emergency release key. The key is described as hexagonal in the user manual that I found on the Internet. I've attached a picture of the top of the swing arm where the key is inserted.
I was hoping someone on the board could help in my finding a supplier who is able to source this vital accessory?
Many thanks!
