Hello all, I've been trying to get a second key fob for my used Prius I recently purchased. It is a Non-SKS fob with black logo in the back. I ordered one from Amazon (new without Toyota logo) and tried to program. It didn't work. Seller sent me a replacement which also didn't work. I ordered another one from eBay's KeylessKing and it also didn't work. Basically, when I put in the new fob to be programmed, the security light on the dashboard blinks twice, then 3 times, back and forth for about a minute. Then it continues to blink. Anybody ever had an issue like this? How did you solve it? If I order a used key fob with Toyota logo in the back, would it make a difference? Thanks in advance.
