All warning lights are on... Please help!!!
 

I replaced the battery on my 2014 porsche boxster S key fob and thought all was well. Car unlocked and started, np. After driving for approximately 5 minutes, all the warning lights started appearing on my dash. ALL OF THEM.

Do I need to reset something? (replaced the battery before without any problem)

Can anyone please tell me why this is happening and what I can do???

Try disconnecting the main battery for 5 minutes and reconnect. Is your battery in good condition or maybe run down from the car sitting? Do you have access to a scan tool? Clear codes with the scan tool?
