Button On My Key Is Missing

[Mr. Freegard]

I purchased a '94 LS400 and the remote button on the key is missing. How can I get it replaced? I seriously doubt Lexus is going to replace the button any more than they would sell the capacitors so I could repair my instrument cluster. Any ideas would be appreciated. Anyone got a Lexus key laying around for a car that no longer lives?

Thank you

I'm not certain if the 93-94 LS remote entry works the same as the 90-92 LS system since there was some sort of revision with the 93 model year, but in the 90-92 LS, the keys and ROM chip came as a set ... i.e. you could not get a key that was "laying around for a car that no longer lives" and make it work in another car unless you also had the matching ROM chip that plugs into the keyless entry receiver in the trunk. So ... if you want to use the electronics in a donor key for your car, you may also need the ROM chip.
