Some of you may know this, but I thought I'd post it for those without pannier keys.
The sort of pannier lock I refer to is on one picture (showing where you may find the key number); a bunch of keys in the other picture.
Key 'section' is if you cut the key across its working length; it's also the shape of the hole in your lock.
If you look at the keys in the photo you will see a) they are all in the same orientation and b) they only really differ in the key section (the profile is a bit irrelevant as only the tip goes in the lock). So there are ranges of key numbers that work many locks, if the key section is similar. The 050 top key is 'stepped' in profile, as is the next key, but then there is a key with a narrow groove and one with a wider groove. The last 3 keys have the groove on the other side.
So, by looking at your lock you might be able to articulate that you need a key with a groove on which side or if it is stepped, etc. The key number is less important.
