Trunk and frunk release on 2004 Boxster S

[Anker]

So here's a mystery and a concern:

Not long ago the trunk open knob stopped working on both of our keys. Both keys light up when the key is pressed, so it must be something in the car that's a problem. But the switch in the drivers door sill still works.

Then today at the PCA NER AX the frunk suddenly refused to open when the door sill switch was pulled, but fortunately it came back, otherwise we would have had to call my wife to come out with her car to take some of the stuff we had brought to the AX.

When I checked the parts listing it looks like the 2003 and 2004 Boxsters don't have emergency cable releases. And all the owners manual mentions is putting an external battery but still using the sill switches.

So here are my questions:

Have any of you experienced these problems and how did you deal with them?

Am I correct that there isn't an emergency cable release?

How do I get the trunk and frunk lids opened if the switches and keys fobs don't work?

This is scary, because it could have happened on the vacation we just returned from to the Canadian Maritime Provinces.

Any help will be greatly appreciated!
