It's been that way for longer now than they actually worked. I should have had it fixed under warranty but just never thought about it.

Is there some way to fix it short of buying a whole new handle?

 

Everything is possible but a new handle or keypad would be easier. Then play w your old one, if you change the led sell it

 

There are guys on the forum who have changed the lights in the keypad. You also shouldn't have to buy the handle, you should be able to buy just the keypad. At least the sold them for the previous model, and I'm sure they should for yours also.
