Key fobs not working - help

[satsana98]

I have a 2000 Boxster S and both key fobs have stopped working. They both have new batteries and the LED lights up on both when the door or the trunk buttons are pushed. Both keys work fine to open the door manually or start the car.

So far I have tried putting each key into the ignition, turning on the accessories, removing the key, and pressing the door button for more than 10+ seconds within 5 seconds of it being removed.

The one odd thing is the LED light on the center dashboard no longer blinks. Is this an indicator that something is not working correctly in the car receiver>

Any other suggestion for what I'm doing wrong or how to diagnose this further?

Thanks!
