Lock and unlock works fine but not with remote.

lock unlock works when doing it manually not with remote.

Battery for the remote is good.

What is this?

How do you know battery is fine. Even if its blinking led it might be low to transmit the signal or maybe the remote is not working.

Cheaper fix is battery than chnaging remote, so change the battery first and then jump for remote.
