accessories » Pannier lock stuck.

While removing my pannier in a hurry, I somehow released the key mid step.
Result:
The black release lever is stuck open.
The key won't rotate to open the pannier.
Help please.

Well that is an extreme option, wessie.

What are the normal steps? Is it possible to manipulate the problematic parts while gently working the key? The mechanism might be straining against a part too strong to be moved by the lock tumbler.

I was able to excercise the key while moving the black latch to free the lock.
Then pulled the seal, then 8 screws retaining the outer case. Next were the 8 screws holding the lock assembly. Some lube on the mechanism freed it to about 80%. Still a bit notchy. I will swap out the lock if it repeats.

There is an item on it on page 2 of this section. Tried to copy and paste


I’m fairly confident I’ve found the problem. If the spring catches and gets stuck as indicated in photo then you can’t lift it up far enough to release the catch.
A bit of care putting it back together should make sure the spring goes in the right place.
Thanks for all the help

Thanks for the link. It is an odd spring seat arrangement.
The backside of the flat plastic lock assembly in the first pic rests against the inner bag spring seat. The spring is held at less than perpendicular. It can (and will) stick with a few coils trapped in between.
I like the idea of clearancing the lock assembly for the spring. It will unbind the less than perfect design.

I filed out a small amount to stop the spring jamming. In my opinion it’s a poor design and there’s nothing to stop the spring moving and getting stuck, which makes it extremely hard to open the catch.

Took the lock units out of my side cases this afternoon after suffering the issue of difficulty opening the planner lids. The springs were trapped behind the plastic of the housing. Two cutouts have now been made to let the spring move over its complete length. Have Opened / Closed the lids numerous times following re assembly and all seems well - no stuck lids!!
It’s definitely not a good design and something BMW need to look at.
