I also may have some progress on this I have a guy who runs a fabricating company who should be able to have a go at producing something, I'm going to go simple and give him my old broken key as a template, the idea being to replicate the original key in metal with a lazer etched trident on me side then keep the original buttons.
My thinking is it should look fairly standard but much better quality, also should be easy to retro fit to an existing key.
Only issue I have come across so far is the IR parts as far as I can see it is mounted direct to the plastic part of the key, so need to work out a way of transferring this to a new body.
Any ideas would be appreciated,
