In a second of carelessness, I lost one of the remote door openers for my '98 Passat. I still have the second remote control, but I would like to ensure that whoever finds the lost remote can't unlock my car.
I did a manual reset to the second remote control to change its code. But will that automatically disable the first (lost) remote? Or does something else need to be done to dissociate a remote control with the car?
