This may be an obvious question...... I bought my bike used so I am not sure what has or hasn't been done with these locks. I have looked inside the cases and see two screws above the lock area and 2 below. Are these the 4 screws or are the ones we need to change behind this plate they hold on? Thanks!
No not those screws don't mess with those!
They are the two screws inside the end of the lock cylinder.
Signs of bad lock that will fall out eventually-The cylinder should be flushed with the mechanism in the front of the pannier and not protruding with no movement. If there is modify immediately.
Peel off the rubber lid in the center. Use a screwdriver or some strong fingernails to pull off.
Then you will see the lock cylinder and the two screws I am talking about. They hold the lock in place.
You will need the goofy star wrench to get those screws out.
Those two screws are made of cheap aluminum or really crappy metal and strip easily from the vibration of the bike or threads are so cheap they just strip over time.
Go get better screws that match thread pitch and size. Dont reuse OEM ones they are crap.
Hence the falling out of the cylinder (locks) while riding and frustration of turning the keys-when cylinders move the lock becomes very finicky to catch gears so loose cylinders compound the finicky issue by 10 fold.
There should not be any movement of those cylinders if so yours is going bad and will fall out at some point.
If someone upgraded the screws they shouldn't be starred, cheap metal, and or you will see lock tight blue paste on them or a lock-nut on them.
Be careful as you will need to put pressure on the starred cheap screws while turning as star head strip easily while taking out.
I would replace the starred head OEM screws with better type.
One last thing for everyone. if your Cylinder happens to fall out and you dont find it and your box is locked (latched shut) There is hope. You can place your finger in the hole and twist to open. Your finger will catch the ridge that needs to be moved to open. Yes it hurts a little but only way to open it unless you have a screwdriver you can do that also but you have to make sure you find the right ridge that moves to move the latch uptop. And you need to do this while pressure on top of lid.
Good luck,
