Is the light on the FOB blinking red when you press the button? Pull the battery out of the FOB. It should have 3 volts. If it does, with the battery out of the FOB, perform a capacitor dis-charge by holding the lock button for 30 seconds. Re-test after this. If it still doesn't work, you will have to program the FOB to the CCM. you will need a VAS OR VAG scanner.
