I just bought another 2005 camry and it only has one functional remote,i see some used ones on ebay that are oem, it says it has easy program instructions, does anyone know if it's just that simple wether I buy used or new aftermarket is it easy to program it to my vehicle?

 

What functions do you want to add?

 

same as the factory remote,lock unlock and trunk release, I have ordered a new Toyota remote but am unsure how to make it work.

 

The FOB will NOT have remote engine start?
