I've 'repaired' many by just dismantling, washing all component parts
under a cold running tap, drying with paper towel and then just leaving
the dismantled parts in a warm place (on top of a radiator/airing
cupboard) for a day. Re-assembly is the reverse of dismantling.

You may find the high resistance is from crud (contaminated sweat from
hands/food/drink) migrating by capillary action between the rubber key
membrane and the pcb. Usually its only one or two keys that stop working
reliably.

You have replaced the batteries?
