Is remote sending signal?

If just replaced battery, try unlocking with key then pushing button. Also, try turning the ignition on (no start) and pushing the unlock button then take it out and try. One of these two seem to work on most VAGs, else need vagcom or similar

remote work before you change battery ?

VW models, manual remote programming:


Open the driver's door window and then close the door,

Turn the ignition on,

Put the remote key in the door lock,

Turn it to the locked position and then press the lock button until the indicators flash or the siren chirps.



(This will only work if the comfort module has been configured to allow manual remote programming).
