I can confirm that the release cable shown in the video you linked is for the 2000 and earlier models with the manual cable type of latch. The 2001 and later cars have an electronic latch.
Hopefully you can find the emergency cable that has been mentioned - normally behind the right side headlight in the fender well. It is a small stainless steel cable and can be hard to see.
If the problem is a dead battery, you can open the latch electronically by applying 12 volts to pin A33 of the blue connector to the module under the driver's seat. If you are not familiar with electronics, I do not recommend trying it though. Here's the video:
