I have a 1993 LS400 with key problems. The 2 master keys function fine as keys but the remote locking buttons fell apart. One dealer told me $500 to replace them because of the chip in the case. Well, there's nothing wrong with the chip just the plastic casing. Does anyone know if the plastic cases can be replaced or where affordable replacement keys can be purchased?
thanks

 

I would look on ebay. That's where I get my key shells.
