Removing the steering wheel cover


Firstly, apologies if this is in the wrong category.

I have a 61-plate Micra Visia 1.2

One of my 'mates' decided it would be a good idea to put a 5p coin in my steering wheel under the cover. Could anyone give me some advise on what the best way to get this out would be please? I have watched some videos and most people seem to go in from the bottom and unlock some levers.
See this link for a image on where the coin was inserted:
Please note- I do have an airbag

Thanks in advance for your help,
