Used Litetouch Parts are typically only available on eBay. After completing a litetouch replacement we typically recommend the owner sells the old parts on eBay.
This isn't an easy process to do as Ebay's valet service does not accept these items to sell on your behalf.
If your not familiar with litetouch you may be surprised to find out that all the keypads are the same.
It's only the number of buttons that that different but buttons can be changed.
Even if you only need a single button keypad those 8 other buttons are hiding under that faceplate.
We doubt you'll want to reuse the prior owner's old button engravings and faceplate so save them!
