Wanted: S2/S3 key fob housing

Looking for the key / alarm board housing / fob for S2 / S3.

I only need the plastic housing as my plastic entry button has disintegrated.

Doesn’t matter if it’s a bit tatty, as long as the entry button is largely intact.

(the key comes apart by 4 screws under the snap-on battery access panel)

Happy to pay any postage!!
