My fob was cracked and I was afraid the buttons were going to fall off.
I bought this Fob for my 2006 LR3 off Amazon: "wwwamazoncom/gp/product/B073TXLYN3" for $9.99 delivered. From Youtube I saw others demonstrating separating the LR3 fob and moving the electronics from one fob to this new one. Take care when separating so that you do not damage the electronics. Fits great but you do need to get the key recut by a locksmith with laser cutting capability. The locksmith cut a new key from my old one in 10 minutes for $25. I had no need to reprogram, the new key worked right away.
