One from 2 of my Boxster S 2003 keys died yesterday. I mean FOB does not work. It looked like batery has gone so I changed it. Red indicator LED is flashing when buton push but it does not remotely open car or trunk or frunk. But I can manualy open car and also start car. Second key still works fine, it was not in use so much.

I red somewhere there is limited volume for each key of car untill memory of unit in car will stop comunicate with key. Not sure if this can be true.
But did not find enywhere how to refresh it or reprograme it.
And only way to solve is buy new key from dealer. Quite expensive solution.

Anyone has any idea?
Thanks a lot in advance.
