Dead Battery Problem

Any battery will wear down over time. The Viper remote start battery will also start to be less effective after 2 to 3 years. Finally, it will die, and the remote start will not work. 


If your remote start is older than 2 years and you are having this problem, you just need to replace the old batteries to address this problem. Usually, the one-way Viper remotes use an A23 or CR2032 battery.

To change your battery, you should follow the steps below.

  • Step 1: Remove the back cover of your Viper remote start.
  • Step 2: Notice the attached battery, and you will see the battery model on its surface.
  • Step 3: Buy the same model of battery.
  • Step 4: Slip out the old battery and slip in the new one in the same place.
  • Step 5: Put the back cover in its place. 

Let’s watch a YouTube video to visualize the method properly:

Defective or Rusty Hood Pin

If your car’s hood pin is rusted out or broken, the cable plug will not go into it. So, it will give the remote start a signal that the car’s hood is open. Hence, the Viper remote start will not work.  


You can efficiently resolve it by changing the old hood pin of your car. If you have done that before, then buy the properly sized one and replace it. If you’ve never replaced a hood pin before, take your car to the nearest mechanic and let him do the work.

Bad Tach Problem

A tachometer or tach measures the operating speed of the engine. It uses magnetic properties. Hence, while getting older, the connection will get weaker. So, when you try to start the car with the remote, the remote will show a signal but die out the next moment. This is when you need to reprogram it.

You need to put the car key in to start the vehicle and put your foot on the brake pedal. Now, start the remote. You will notice the park lights flash once. That is, your tach is reprogrammed, and your Viper remote start will start to work again.
