A rear hatch that will not open usually fails at the latch or its release actuator, not the struts. The struts only fail to hold the hatch up once it is open. Here is how to tell the difference and get into the car.

A small motor inside the hatch handle pulls the latch open. The motor burns out from use. You hear nothing or a faint click when pressing the button. Replace as a handle-and-actuator assembly on most cars. Cost: $150 - $400. DIY: Medium. Severity: Low.
Get a Free AI Diagnosis →The rubber button on the outside or the dash-mounted switch wears out. Try all release options (key fob, dash button, outside button) - if one works and another does not, the dead one is the switch. Cost: $30 - $150. DIY: Easy. Severity: Low.

Press the outside hatch button. Then the inside dash button. Then the key fob. Note which work and which do not. Each one is a separate switch into the same actuator, so the pattern tells you the fault.
Find the "LIFTGATE," "PWR HATCH," or "REAR" fuse (usually 20-25A) in the rear or under-dash panel. Inspect and replace if blown. If it blows again, the actuator is shorted.
Fold the rear seats down and crawl into the cargo area. Most hatches have a small plastic plug on the inside of the hatch trim - pop it off to expose a manual release lever or cable. Pull or slide it to open. Owner's manual shows the exact location.
With the cargo trim panel off, locate the latch assembly. Apply 12V briefly to the actuator's motor wires. If it clicks and releases, the wiring or switch is at fault. If it does not, the actuator is dead - replace the latch-and-actuator assembly.
If your scanner shows one of these B-codes (body) along with the symptom, run a free AI diagnosis to confirm.

Fold the rear seats down, climb into the cargo area, and pop the small plug on the inside trim of the hatch. There is a manual release lever or cable behind it. Pull it to open.
The release motor is energizing but cannot pull the latch open - usually a worn motor or a jammed latch. Spray penetrating oil into the latch, work it by hand, and retest. If still no luck, replace the actuator.
It will kill the fob-based release. But the dash button and outside button should still work. If everything is dead, it is the car, not the fob.
$150 - $400 installed depending on whether the actuator is sold standalone or only as a complete handle assembly.
Different part but same kind of failure. Both are small electric actuators that burn out from repeated use after about 8-12 years.
Sometimes - if the latch is sticky from dirt or cold, a thump can free it. Do not make a habit of it; thumping breaks the actuator faster.
