L-keychain-1/B compatible to liftmaster T501L5?

Compatible Remotes
#1

I didn’t see help video for my style liftmaster specifically so I’m wondering if the remotes I got are even compatible.

Thanks

Hi,
I just checked your manual, and the model seems to be industrial duty door operator.
Our remote is designed for garage door, so it might not be compatible.
Thanks.
