My2005ES330 Posted September 27, 2009 Share Posted September 27, 2009 I bought a spare remote key for my '05 ES330 on-line and brought it to the dealer to have it programmed and it didn't work. Called the vendor and they kept telling me that it is guaranteed to work and dealer didn't know what they were doing. I then tried my local locksmith and he couldn't program it either, he told me that probably what I got was a '03 ES300 transponder. Called the vendor again and they told me that '03 ES300 and '05 ES330 transponders are compatible with fcc id HYQ12BBT. Is this true ? I've going back and forth, wasting time and $ and the darn is still not working. I need a key spare key, where can I get one that is supposed to work.

gabep Posted September 27, 2009 Share Posted September 27, 2009 Had the same problem with an ebay vendor. Finally had to get the key from a dealer as the after market keys don't work on the 2005. The vendor refunded my money. Quote Link to comment Share on other sites More sharing options...
kcpartsguy Posted September 29, 2009 Share Posted September 29, 2009 '03 and '05 transponders are definitely different. I would send it back, i might have an old transponder laying around here, I'll have to look. Quote Link to comment Share on other sites More sharing options...
