Remote does not open the car door?

Okay, the remote doesn't work. Do the interior switches work for the locks? Driver's should lock and unlock all the others. If the interior switches work, it's most likely to be the FOB itself. Most lock shops can test to see if it is working properly. They get moisture inside behind the buttons and over time they fail. The trunk release issue is commonly the ground for the actuator in the trunk.

Okay, if none of the switches work the first thing to check is the power from the fuses and the ground connection that both systems share. So, get a cheap test light and use it to test for power at fuses 7 (Hold key in start to test), 15 (key on) and 23 in the fuse box under the dash and test fuse 8 in the junction box under the hood.

If they check good then we need to test ground 200, it is behind the trim panel in the passenger footwell. It will be a number of wires all connected together and bolted to one point, The wires like to corrode and break off in those types of grounds.
If the powers and grounds check out okay on that end the next step would be to check for the powers and grounds at the door control module in the driver's side door. You can check two of them at the passenger side door switch. You should have battery voltage at the Light Green w yellow wire on pin 4 and with the key on power at the White w violet wire on pin 1.
If those are there access the control module in the bottom of the driver's door. Check the connector there for corrosion. Then check for battery power at the White w light blue wire on pin 4 in con 501c and power at pin 10 in con 501a with the key in start.
I suspect you will find either a blown fuse under the hood, a bad ground or the power wire (White w light blue) is broken in the flex between the door and body.

Okay, with that information it is likely the driver's door control module. It is easy to mechanically replace but first reconnect the passenger side switches just to be sure they don't have a connection that isn't shown. If that doesn't do it then the module is likely the issue. However, you need a scan tool to download the as built program for the replacement module.
