Remote Key (I searched)
 

1998 Boxster
I have two remote keys. One of them quit working so I changed the battery. It still doesn't work. On the good key, when a button is pressed the LED lights up continuously as long as the button is pressed. On the non-working key, when a button is pressed the LED briefly flashes once and quits even if the button is held down.

I replaced the battery again, etc but all to no avail. Any suggestions or do I just go give the dealer all my money and get a new key fob?

Thanks for any suggestions.
