My fob wont unlock the doors on the car. Does the fob need recoding or somthing and how do i do it?

Put key in ignition, push and hold either button and turn key to main ignition. What should happen is that the central locking will lock and then unlock itself and take the key out of ignition. Then try locking.

The usual re-sync method is, as you said, doors closed, ignition on (dash lights illuminated but DONT start engine) and push button on fob. Doors should lock then immediately unlock.
You may have to push the button a few times for it to work.
However, I found on my Vectra it would only re-sync if I got in the car, locked the doors using the knob on the door, and then ignition on, push button etc., others have said they have to leave the drivers door stood open for it to work.
If none of these work you may have to get a full reset done using diagnostic equipment such as tech-2, op-com etc.
Doesn't have to be a Vauxhall dealer, lots of independents have this equipment and will be cheaper.
To do a full reset you will need the security code for the car, which you will find on your "Car Pass" card.
Hope this helps.
