I need help!!! I lost my transponder from my only master key. I have a 2001 GS300 what can I do? The Lexus dealer wants about 800 dollars. Can I buy a key from ebay and have a locksmith flash my computer to reset a new key?

Dude, you meant $80.00 okay? Not $800.00. Got it?

I just had this issue with a 98 gs300 I bought with only the valet key. MOST dealers not all will charge you for 2 new keys and labor and will replace the ECU for the alarm system since they say they can't reprogram the transponders if you don't have the originally programming.

The option I went with is buying a brand new master key with the transponder from the Sewell Lexus parts site online for 150. Then I asked them what they would do and he said they just re-flash the ecu but most of the charge is labor for pulling and then re-installing it. So I found a locksmith with the capability to do so, pulled my ecu and took it to him. He re-flashed it, cut the key I had bought, and programmed it to the ECU for 150. Had he had to pull the ECU himself he said it would have been 350.

That's the route I would go unless you want 2 new master keys then your getting closer to the range of what the dealer charges and the cost difference is less substantial.

If you can find a key with a transponder synced to the ecu like the one I bought

I am all woman. LOL The dealer wanted $800 dollars for all, that would be two keys and to change the ECU for the new keys.
