Symptoms
- Trunk release button/remote does nothing
- No click or motor sound from the trunk area when trying to open it
- Trunk may open fine from a mechanical key cylinder if equipped
- Possible interior trunk release also not working
Likely causes
- CommonFailed trunk latch actuatorThe small motor that releases the latch can wear out or jam over time.
- CommonBlown fuse for the trunk release circuitA blown fuse cuts power to the release button and remote function.
- PossibleDead or very weak 12V batterySome vehicles need enough voltage to operate the electric trunk release.
- PossibleBroken or disconnected trunk release cable (cable-operated trunks)Older or simpler systems use a cable that can snap or come loose.
- Less commonFrozen trunk latch (cold weather)Moisture in the latch can freeze shut in very cold conditions.
What to do
- Try every available method: dash button, key fob, trunk button on the key fob, and a mechanical key cylinder if your car has one.
- Check the relevant fuse for the trunk release circuit in the fuse box.
- Check the 12V battery's charge, especially if other electronics also seem weak.
- In cold weather, try gently warming the trunk lock area in case it's frozen.
- If it's a cable-operated trunk, check for a snapped or disconnected cable through the rear seat pass-through or trunk liner.
- Have a shop access and replace the latch actuator if fuses, battery, and mechanical checks don't resolve it; they can also open it manually if you're locked out.
