If you have locked your keys in your Prius, do not panic.  Retrieve another key right away or use the following tactic to get into a locked Prius.

How to unlock a Prius with the keys inside?

There are diverse ways that you can enter the car door window in a Prius to unlock the door.  This is something that you might have to end up doing if your key fob has a low battery and it’s locked within the car.  Of course, I suggest you call a locksmith, but as a last resort, this following method will work:

  1. You need to purchase a kit that will allow to enter the window of a Prius car door so that you can then unlock the door.
  2. I recommend the AIDA Essential Kit for unlocking your Prius.  Click here for current pricing on Amazon.
  3. The first step is to use a wedge to hold out the window slightly at the top since there will be less chance of causing damage in this area.  There is a plastic wedge that comes with most kits.
  4. Once a small space at the top of the window has been created, you can force half of the air wedge into the opening.  Now slowly pump up the air wedge until you feel that there is enough space for the long reach grabber. 
  5. In Pruis, you need to use the long reach grabber to pull open the latch on the inside of the door that will allow you to open the door. 
  6. Push the grabber into the space that has been created at the side of the door in the Prius.  
  7. Make sure that if need to add the extensions, that you tighten well the screws.  Many users have stated that if the screws are loose, that the extensions will spin making it hard to pull on the lock mechanism in the Prius door.
  8. Now slide the grabber over to the locking mechanism and grab onto the outer side of the lock mechanism.  Now pull on the lock mechanism until the door unlocks.

Make sure that you change the battery in your key fob right away so that you can avoid creating the same scary scenario for yourself.

Besides just locking the key fob in the Prius, what could go wrong if you have left your Prius running while you are on an errand? What if someone enters your car and drives away?  Will the engine continue to run?

How far can a Prius go without the key?

If you were to leave your Prius running and you had taken the key fob with you, it would continue to run.  If will beep to alert that the key fob cannot be found.  It will not turn off until you turn it off.  It is a safety feature, since if the Prius stopped in mid route just because of a dead key fob battery, it would be dangerous for the driver.

 if your Prius model is able to accomplish a range of 25 miles on a full charge, that is the distance that you would be able to accomplish even if the key fob is not within the car once the car has been started. if you happen to have gas, once the gas motor kicks in, your mileage is going to increase. Prince you could travel as much as 600 miles on a full tank plus a full charge even without the key fob in the vehicle.

Once you have stopped the car, you will not be able to start it again without using the key fob.

Since you’re worried about the security of your Prius if you happen to leave the car running, another concern that you might have is whether it is easy to break into a Prius.  

Is it easy to break into a Prius?

It is possible to break into most cars.  A lot of Prius owners assume that its some high-tech method that’s being used to break into the car.  Nevertheless, it is usually just the old school way of manipulating the locking mechanism.

What is done is that the thief using a slim Jim to gain access to the lock mechanism that’s within the door of a Prius.  There’s not really any way to totally prevent someone from using a slim Jim on your car door even if it is a car that’s more high-tech such as a Prius or Lexus. 

I searched online for more high-tech methods that people are using to break into a Prius and I came across an article in the New York Times.  One owner had been broken into three times during a month, and he was getting very frustrated. The police department told him that he had forgotten to lock his car.  He finally noticed someone simply unlocking his door by holding up tiny black device that allowed them to open the car door quickly.

He researched this device. He discovered that it was a device that amplifies the signal from key fob.  The Prius was tricked into believing that the key fob was close by allowing the car doors to be unlocked. 

The best policy is not to store anything that’s valuable within view in your Prius. Keep valuable items in the glove compartment or tucked away in the centre console.
