Megane 2 key - missing component

[jhb123]

Hello!

I hoping someone on here might be able to tell me which component has gone AWOL from my Megane 2 key. I think it's probably a capacitor based on a Spanish spares website, but I need to find out the specification in order to replace it without paying a premium for a delivery from Spain.

I'm not sure how to upload a photo, but it is located between the two battery solder points and is marked in this picture https://www.ovisat.com/_archivos/produc ... 1482427522

Thank you for your help!
