I have a 2009 Toyota Rav4 that I purchased at the auction. The key fob was not have unlocking the doors so I had to use the physical key. The rav4 has a push to start. It doesn't try to start at all when I push the button. I've replaced the battery in the fob, held it on top of the push to start button, etc. Dealer says it has three computers and they are not communicating with the key. Said previous owner might have replaced the pcm. They are saying it will cost $2,000-$3000 for them to now replace the pcm? Does this sound right? Is there any other option you guys know of?
