How to Start a Jeep Renegade Even with a Flat Key Battery

Model: Jeep Renegade 520, MK 1, BU - Years 2014-2026
Part: Key

Need to get home but your Jeep Renegade key has decided to stop working? Don't panic. Today, with the help of our short video tutorial, we will show you how to start the car even if the key battery is flat. Get in the car and try to start the Jeep normally. If the key struggles to recognise the signal, take the key and place it on the lock. You will notice immediately that the key will click and start the ignition because there is a small microchip on the back of the key that allows you to start the car regardless.
