How to Open Your Toyota Prius Trunk (a.k.a Boot) When Your Battery Is Dead

It's bad enough that you got into your Toyota Prius, pressed the Power button, and nothing happened. It's made infuriating when you discover that your trunk lid doesn't open because that little black button that pops it up is battery operated.

If you want to jump start your Toyota Prius with jumper cables, you DO NOT NEED TO OPEN THE REAR DOOR. Just like a regular car, there is a regular car battery under the hood. Open the hood, and you will find it under the black cover in the back, right corner. I've included a great video at the end of this article with step-by-step instructions to jump-start your Prius.

However, if you are awaiting roadside service or a friend with a car and jumper cables and you need to get into the trunk in the meantime, this is the problem I will show you how to solve. You probably tried to consult your owner's manual and found easy-looking instructions. An easy two-step process: 1) remove the cover and 2) pull the lever.

If you are reading this, you learned that 1) it's not an easy two-step process 2) there is nothing in your trunk that remotely resembles either of those diagrams and 3) it's not easy to get to the trunk when the rear door doesn't open.

Here's a step-by-step photographic guide to open your Prius trunk (a.k.a Boot, a.k.a Rear Door) when your battery is dead.

Step 1: Flip Down the Rear Seats

Push the button next to the seat belts on both rear seats and pull down the seat backs.

To begin, you need access to your trunk from inside the car. Unless you are exceptionally small and Barbie doll thin, you will not fit through the narrow opening between the top of the rear seats and the inside of your roof. Of course, this is where small children can come in handy, but that's the subject for another article.

Press down on the button, and pull down the seat backs for both rear seats. You can now go caving into your Prius trunk in search of the Holy Grail: The Door Lever.

Step 2: Pull Back the Carpet to Expose the Tool Box

Hopefully, you are one of those rare individuals that doesn't actually store anything in their car trunk. If you are not, step 1a is to empty your trunk.

Once empty, you can pull back the carpet to expose the toolbox. You are looking for the tiny fabric tab very near the rear door.

Step 3: Pull Back the Tool Box Lid

You need to pull the tiny fabric tab near the rear door to open the tool box.

Pull on that fabric tab to open the toolbox lid. It should open easily, but If the lid resists you, take a breath. It's not trying to add to your already bad day, it's just locked.

To the left and right of the tab, respectively, are two locks. To unlock the toolbox, the arrows on the locks should point to the side (left for the left side lock, right for the right side lock). If they point to your rear door, they are laughing at you and keeping your toolbox lid locked.

Turn the two tool box locks to 3 o'clock and 9 o'clock. If the arrow points at your closed trunk lid, your tool box lid is locked.

Step 4: Remove the Cover

We have now joined the owner's manual already in progress... you can now remove the plastic cover.

The toolbox lining has a small plastic cover that protects access to The Door Lever. You can easily pry it off. If it makes you feel better to express your increasing anger at this process, use a screwdriver and damn the owner's manual... pry that cover off and don't use a rag to protect it. It's a cheap piece of plastic whose sole purpose is to obscure access to the door lever.

Personally, I threw my cover out. It was gratifying, and it will never again block my access to the door lever.

Step 5: Pull the Door Lever

Pull that silver, backward c-shaped lever toward you. The trunk door will pop open.

This is where the owner's manual writers were seriously smoking something. The manual makes it appear that 1) this lever is easy to find and 2) you can pull it up.

First of all, you are going to have to feel around for this lever. It's buried inside the rear door and, because you are already reaching through the toolbox liner that is IN the body of your car, it is below your eye level. You head won't fit into the toolbox to look the door lever in the eye.

Second, the owner's manual arrow is drawn incorrectly. You couldn't possibly pull that lever up from the position in which you are contorted. It defies physics.

Reach two fingers straight into the black abyss, once you feel this lever, pull it TOWARDS you. Voila! Trunk door pops open, you can push it up, and feel the freedom like Tim Robbins at the end of The Shawshank Redemption.

Finally, Relax

Your trunk door is open. Take a breath. Lie in your trunk, enjoy the moment, drink that margarita. You still have to jump-start your Prius.

      Great instructions

      I can’t believe Toyota passed nhtsa requirements for releasing the latch if someone is locked inside

      That’s a horrible design for a release latch and near impossible to access

      Thanks for simplifying the process. This is a lifesaver. Removed my 12v battery for charging and also had to disconnected the broken trunk opener switch for replacement. Wedged a piece of cloth thinking the trunk would not get locked but was wrong. Was totally stuck, your article showed me the way out.

      i cannot begin to express the depth of my gratitude for both your website & SPECIFICALLY THIS POST! not even the 2-inch thick bentley publishers prius repair and maintenance textbook had any reference to this emergency trunk release latch & attempting to decipher that crap toyota manual drawing has caused me to bleed and curse like a sailor!

      climbing thru a dead prius in over 112 degree blazing southern CA heat like a sweating acrobatic ninja ( more times than i care to admit ) - in order to access the external car jumper ( which i bought after discovering that AAA does not carry replacement Prius batteries - regardless of the popularity of these annoying golf cart type vehicles may be ).

      since car thefts & break-in’s are a daily occurrance this personal jumpstarter has to be stowed in that insanely designed carpet covered, plastic compartment box buried trunk storage area.

      the next thing i need to look-up in your BRILLIANT SITE is how to replace the batteries in both key fobs....

      you are a godsend & i cannot thank you enough!

      Just like a regular car, there is a regular car battery under the hood.

      Nope, the battery is in the trunk you are trying to acces in your tutorial...

      We would never have been able to open the hatch without your article. Battery seemed dead but as soon as the hatch opened everything came back on and off we went. Somehow the hatch in the closed position shorted out the system.

      So useful, Thank you for your advice, was able to open and am now charging the battery, hoping I can get started to make it to an Advanced Auto to replace the battery. If not I will try jump starting, and if that doesn't work will borrow the wrenches to take the battery in for a replacement. I had no idea there was a small battery in the car, this thing lasted 10 years!

      Do you mean pull the lever counter clockwise or towards you (front of the car)? If it's the front of the car, does it require some force?

      I'm trying to release the hatch as I have a piece of cloth stuck in the latch.

      Thank you, thank you. When we called the dealership for help, we were told to jump the 12V from the other battery to open the locked hatch. Well I followed your directions instead and had success. I'm 73 YO woman who climbed into the trunk via back seat and figured it out thanks to you. If I can do it anyone can! There's gotta be a better way Toyota!

      Your most helpful bit was: "Reach two fingers straight into the black abyss, once you feel this lever," That worked! Actually, at first it didn't because I was by myself, but then somewhere I read that you need 2 people, one inside & one outside, and that DID work! Thank you! (And it was so FUN, having to clean out the entire trunk through the middle seat opening!)

      My problem is the trunk won't open period. Pretty sure the battery is fine cause I don't have any trouble starting the car. With me, it just won't open. It's like the lock doesn't get a signal.

      Thanks -- it worked! After many tries I first got it to open by charging the shorted out battery from under the hood. But then, after removing the battery, I closed the hatch gently, thinking the thickness of the jumper cables would keep it open. I was wrong. The mechanical lever was the only option left.

      This looks like a 2004-2009 Prius.

      Just wanted to say that the battery is not located under the hood. You can jump-start it from the under the hood, but the battery itself is at the rear-right side. Beside the tool box lining, under a lid with a strap attached.

      BTW: Went here to check how to open the trunk to change my dead battery, thnx for the nice instructions. ;-)

      what if the battery is so dead that even using a key wont unlock the car doors, thus you cannot gain entry into the vehicle at all????? how do you jump a locked prius with no entry into it, or to the hood!

    • MickiS profile imageAUTHOR

      It's the back left if you are sitting in the car, but since the point of reference for the battery door is standing in front of the car facing an open hood, it's on the reader's right.

      Btw, it's always on that side of the car, but that is not always the driver side. The driver side of the car is the right side of a car in 164 countries including Great Britain, Japan, Australia, and New Zealand, just to name a few.

      Technically, it's the back left. The drivers side is always the left side.
