According to the information provided by the Japanese manufacturer, the word “HR-V” is an abbreviation for “High Rider Vehicle.”The Honda HR-V is a subcompact automobile that can seat up to four people and made its debut in Japan and Europe in 1999.

Frequently Asked Questions

Can I start my HRV with a random key?

During the manufacturing process of the HR-V car, Honda inserts a one-of-a-kind code into each key and then matches those codes with the immobilizer system in their vehicles. This makes it such that the automobile can be started by no other key except the one that came with it.

Is it possible to start a Honda even if the battery in the key fob is dead?

To start a Honda with a dead key fob, move the tab on the backside to reach the physical key. This will allow you to start the vehicle. When you enter the vehicle, you can start it by putting your foot on the brake and holding the key fob right next to the button that says “START/STOP” simultaneously. After that, start your vehicle by pressing the button twice.

Bottom Line
