How do I program a new OEM key for my 2001 Daewoo Leganza so it locks and unlocks the doors?

Hi this is how you do it
first off make sure the alarm system is off then put the key to be programed into the ignition turn ignition on then off within 5 seconds this is then in program mode press the lock or unlock button 3 times within 20 seconds and then the central locking should start working indicating the remote is now programed...hope this helps please vote thanks
