I ask as I am in a similar situation to many on here where passport works around the world and including GLA and EDI but has never worked in T5 or T3 at LHR. I have taken to just joining the queue for an agent.
Yes it is worth trying another and no your passport will not be locked by a failure. Sometimes the helpers will send you to the next gate. I have seen one gate fail several people who then get though on the next gate.
