Hi Guys Recently I bought a Tarago Sep/2000 new shape, previous owner only gave me 2 keys, one main key and the other is a spare key, they are just a standard keys without remote. My questions is can I add a remote to it and program it so I can have a keyless entry? if not then what are my other options? Do you think buying a new (Toyota second hand) ignition (with remote key) and a computer would fix the problem? Thanks guys
