how can I put remote control back together?

the remote control key for my 99 Clio opens too easily. The last time it did a bit came loose - a thin metal strip bent to achieve a springiness. I do not know wher it should fit. Does anybody have a schematic?

FWIW I think it is an IR key.

THanks John

p.s. I have 2 new batteries and guess they go +-+-
