Q1:I have gen 2 i have two keys one master key with no buttons and the normal 2 button key when i try this i get a beep but nothing else key led flashes so i think its oki as somthig must be registering how come i cant get it to work
A1:Try to start from the very beginning, removing the key from the ignition and manually locking the doors and unlocking them
Q2:Is this for the lock and unlocking of doors buttons on the Key itself? coz my key wont open the doors with the key buttons, i have to physically insert the key in the door to open doors. I bought a new Battery for the key but the problem still continues….
A2:This is for the remote unlock/lock functions. You have to have both keys for it to work for some reason. If 1 key doesn’t beep try changing the batteries. I got 2 fresh batteries and it worked fine.
Q3:What to do if you only have one central locking key?
A3:you need two keys to programme the keys.
