Only they can be opened from the inside. Previously, there was a problem with their closing. The door wouldn't lock when I pressed the remote. Is it the fault of electronics?
There may be the most trivial reasons, ie "shaky contacts" in and around the castle. I had the same thing in the P-406 - the pilot closed once, and sometimes it did not. Only by inserting the key directly into the lock could it be closed or opened. There was no reasonable rule, the locks just worked as they wanted. As soon as I sprayed the spray well inside all the locks, the fault disappeared as he took it away with his hand.
I specially paste a photo of the preparation bought in the "ant", because only he remedied the problem - no other. I also advise you to pay attention to the inscription: "SECURES AND DEFROSTS LOCKS". So let's have this specialty at hand.
