To code a new remote with no existing remote is possible.Originally I heard it was possible using the normal method as shown in the pdf on the previous page.The part that is different than if you have 1 remote already is to disconnect the battery for 10 minutes(make sure you have the radio code) or disconnect and then reconnect the remote module which is located under the steering column(easier).Now even though I programmed all my keys and second remote on 1 of our Corolla's i didn't manage to get this to work on the other 1 with no remotes..However I took it to a dealer and watched him do exactly what I was trying to do and it worked.He didn't charge me anything.

I was just searching for how to program the Corolla One button remote and came across this thread(and thanks for that info).I thought I would add some info. The key required for a 2005 Corolla Ascent (and earlier I Think)with separate remote has a 4C chip. The Genuine Toyota remote is cheaper from Toyota than Ebay $43(inc GST) I bought a key blank of Ebay ~$25 and programmed it using the original key and the "pedals Method" = Free The first key cutter in the shopping centre only charged $10 to cut the key.:) Total Cost of New Key and Remote Approx $78 Hope this helps someone.
