Symptoms
- Pressing the trunk button on the fob or dash does nothing
- No click or motor sound from the trunk area
- Trunk can still be opened with the key or a manual release
- May have started after a jump-start or battery work
Likely causes
- CommonBlown fuse for the trunk release circuitA specific fuse often controls this circuit and can blow without affecting other functions.
- PossibleTrunk lock switch engagedSome cars have a physical lock switch in the trunk that disables the electric release when set.
- PossibleWorn or stuck latch/actuatorThe motor or latch mechanism can wear out or jam, especially in cars with heavy trunk use.
- PossibleDead 12V battery or recent battery disconnectSome systems need to relearn or simply won't operate on very low voltage.
What to do
- Check the fuse box (often listed in the manual) for the trunk or hatch release fuse and replace it if blown.
- Look for a small trunk lock switch inside the trunk lid or trunk area and make sure it's not set to locked.
- Try the release from both the fob and any interior or dash button to see if only one input fails.
- Listen closely at the trunk when pressing the button for a click or hum, which suggests the latch is trying to move.
- If there's an emergency trunk release cable or handle inside the trunk, use it to open the trunk manually for now.
- Have the 12V battery voltage checked if this started after other electrical issues.

When to call a pro
If the fuse and lock switch are fine and it still won't open, a mechanic can test and replace the latch actuator or wiring.
