I have a 2000 GS300, and lost the master key. I now have ONLY a spare key. The dealer says that they cannot make another key without the master key, and they'll have to replace the computer in the car - very expensive. Is there another way to make a key?

Thanks a lot,
Ram

The master key is linked to the computer I dont believe there is another way. making a new master key even with the original is a process in itself

Thanks Donny for your reply. This is just too bad, that a lost key will end up costing about $2,000! I wonder if one can find a computer and keys from a junk yard?

I have the same problem... how much is to replace the computer?

Although not every dealer will tell you this, I found out from one dealer that Lexus provides, for free, the computer, a $1500 device. But, they require you to buy two master keys, in addition to installation labor charges, totaling to about $900. You must shop around. You can also call Lexus and ask the they provide a discount, as this was an "admitted" design flaw through 2003, and they changed the design in 2004, making it like other cars. Hope this helps.
