Second key not working

[fredgroves]

Any idea how to resync a key?

Battery is good, light is flashing away but it does nothing.

Found this on an American VW dealer website:

If the battery is not the issue, your remote control vehicle key may need to be resynchronized. A remote control vehicle key can get out of synch when the buttons are pressed outside of operating range. To resynchronize the remote control vehicle key, follow these steps:

–          Unfold the key bit on the remote control vehicle key.
–          Remove the cap from the door handle on the driver door.
–          While standing immediately next to the vehicle, press the unlock button on the remote control vehicle key.
–          Manually unlock the vehicle using the key bit within 1 minute.
–          Reinstall the cap.

Think it relates to a Mk7 Golf, but I don't imagine keys change that much.

Have you tried putting both keys in the magic cup holder (where the little key logo is)?

Suggest trying another brand new duracell battery cheap ones can cause this.
