Peugeot Key Fob Repair. Any Recommendations?

[Goliath 94]

I have 2 key fobs for my 405, one works fine apart from having to press quite hard but the spare doesn't work at all. It worked fine when I got the car but stopped working a few months ago for no apparent reason. It turns out that the infra-red bulb is not functioning, the red light still works though.

 

Does anyone know if it is possible to get it repaired? If so any recommendations as I have had no luck on google.

 

I can get a replacement from Peugeot but it is £91
