Canon Speedlite 430EX II Difficulty unlocking


Hello everyone. I am having difficulty switching the Speedlite from the locked position to the unlocked position. This happens whether the Speedlite is on the camera, or off. I spent at least 5 minutes attempting to get it unlocked. Finally thankfully I was able to get it unlocked but it was really tough.

Once it was off the camera I moved it back and forth between the locked position to the unlocked position. It is slightly better, but it is still really stiff.

I bought it from someone on Ebay and he said he only used it a couple of times. Perhaps it will become less sticky over time? 

I had this problem before with another 430EX II. Has anyone else had this problem and is there a fix? 

I was thinking of putting just a tiny bit of lubricant in between, but I don't want to to take the chance of doing that without getting feedback.

Hello ShadowandSoul,

It should "loosen" up a bit with further use. It is not recommended to use any sort of lubricants on the flash unit, unfortunately.
