Owners Forums for Ford and Volkswagen MPVs / SUVs

hi guys

i picked up a galaxy advertised as having 2 keys. One key has been used extensively, the other one seems new/still had an identifying tag on from the first owners (lease co).

The battered fob works fine for everything, but the new fob gives me some trouble..

The buttons don't lock/unlock the car - the battery seems to have power (tongue test) but I'll try replacing it. I was wondering if there's a way to re-sync it with the car (like I could on my old BMW - the immobiliser/NFC chip circuit was separate to the radio circuit that unlocked the car, so while the key could start the car, it wouldn't remotely lock/unlock it unless a "turn the key to position 2, then 1, then 2, then 1, then 2 then hold the lock button for 10 seconds" type process was followed. Is there a similar one for the galaxy that I can try to get the buttons working?

The fob is unreliable at starting the car. Most of the time it says "no key detected", but I did succeed in getting a start by holding it near where the key would have been inserted (in the 90s). I've no idea if the transceiver ariel is around there - if it's elsewhere, where is it? I'd like to try holding the fob closer and see if it's more reliable.. On the occasions i've succeeded in using this fob to start the car I get frequent warnings like "key is outside the vehicle"; is there a fundamental problem with the fob that I can resolve?

Changing the battery hasn't made a difference, alas
