keyfob

After battery change my keyfob is not working anymore. It seems like it lost its pairing with the car. Is it possible to pair it or reset it yourself or do I need to go to the Porsche dealer to have them fix it? All advice is appreciated

I have a set of OEM Taycan Cross Turismo Clear Side Marker Lights purchased from Suncoast. They are new and never installed. These will only fit the Cross Turismo. I also have a pair of aftermarket (AliExpress) chalk color keyfob covers. I never used them so I cannot comment on fit and finish...
