Buttons on key stopped functioning

Buttons on key stopped functioning, i used to be able to lock or unlock the car or sound the horn but yesterday the key seems like its gone dead, i opened it up expecting to find a small battery but if there is a battery in there i cant find it.
Heres a pic of the key= https://images-na.ssl-images-amazon.com/images/I/51futzXR2wL._SL1000_.jpg

There is a battery, plenty of videos on youtube showing how to change it.
