How do you re program a Hyundai sonata key fob?

Answer 1

Actually on my 2003 Hyundai Sonata gls i had the same problem...there is a manufactuer alarm that should set off when u put the key in and turn.. do that one more time(BUT makng sure alrm goes off then do it again) then don't take the key out turn offthen set it in the acc. position in the ignition after the alarm goes off then wait about 5 to 10 min and turn on by then it should have reprogramed and kick on..the third time is when you should be waiting for the programming to be down...its very very important that you do the programming on the third time...because the computers are built in the car and not built like most other American made cars....
