Viper vehicle start systems are among the most trusted ones in the market. But that doesn’t mean that they are always perfect. The Viper start systems may sometimes stop working for several reasons, and owners get scared when no blue light shows.
The probable reasons behind the Viper remote start not working with no blue light can be the car being in garage mode, a faulty head switch, a dead battery inside the remote, vehicle incompatibility, loose connections, or even a dead battery.
Let’s walk you through these problems and solve this problem together.
Potential Reasons Behind Viper Remote Start Not Working No Blue Light

Many remote control systems show problems at this time of the year due to extreme heat. So you don’t have to panic. Let us walk you through the probable causes behind this problem.
- The car went into Garage Mode.
- Faulty head switch.
- Dead battery in the remote.
- The vehicle is not compatible.
- Loose connections.
Now, let’s dive deep into the solutions of these problems.
Troubleshooting Viper Remote Start Not Working No Blue Light
Follow this troubleshooting process one by one to solve your problem.
Reason 1: The car Went Into Garage Mode
If you can lock and unlock the car through the remote as usual but can’t start the car through it, your car is in garage mode. The probable reason behind this problem can be someone unknowingly pressing the remote’s buttons, causing the remote’s programs to go berserk.
Every remote controller has a valet or garage mode built into them. Take out the remote manual and search for how to get out of garage mode. If you need the manual, call the company’s service center and allow them to help you through it.
Reason 2: Faulty Head Switch
The most significant factor that may stop a remote starting from working is a broken or absent hood switch. Your vehicle’s engine cannot start when the bonnet is up, thanks to the mechanism underneath the hood. It’s a security precaution intended to stop your car from igniting by accident if someone is operating in the engine area because an accident might happen.
Check if your hood is shut correctly or if the hood switch is working properly. If the hood switch is broken, replace it with a new one.
Reason 3: Dead battery Inside The Remote
Rechargeable remotes have batteries inside them that need to be charged occasionally. Have you checked the charge of your remote? Is it fully charged? If not, then set it. If yes, then you may have to change the batteries.
Dead batteries can cause the remote to stop working. It won’t start the car or show any blue lights either.
Reason 4: The vehicle Is Not Compatible
Are you sure you got the right remote for your car? Often than not, we buy remotes that aren’t compatible with our car. All Viper remotes are not compatible with all vehicles. So, make sure you have the right remote for your car.
Reason 5: Loose Connections
The Viper remote start system connections can become loose or even disconnected during driving. If the remote is not starting the car and not showing any blue lights, there is a possibility that the system in the car is not working altogether. So, go through the Viper remote start system and check if every connection is as it should be.
In this case, you can take professional service if you need to become more familiar with the system.
So, these are all the probable reasons behind the Viper remote system failure. Go through each of them carefully, and your problem should be solved.
How To Replace Viper Remote Battery
Here is a step-by-step process for you if you find out the battery inside of your Viper remote is dead and needs replacement.
- Identify the type of battery used in your Viper remote and get it from any electronics shop. You can find out about the battery from the remote’s user manual.
- Open the back cover of the remote using a screwdriver.
- Remove the old batteries using a pen or a pencil and insert the new batteries.
- Screw the back cover in its place.
- Test the remote.
How To Reprogram Viper Remote
Here are all the steps you need to follow to reprogram your Viper remote.
- Get inside your car and close all the doors and windows.
- Insert the key into the ignition but don’t start the engine; set it to ‘On,’
- Locate the valet switch; it should be somewhere under your side dashboard.
- Press the valet switch once and see if you hear any beep from the start system. It indicates that the remote has entered programming mode.
- Now, press and hold down the valet switch. You should hear a second beep from the start system, do not release the valet switch.
- Release the valet switch and press any button from the remote that you wish to reprogram. You should hear a third beep now. It indicates that the controller has been programmed successfully.
- Remove the key from the ignition, and the Viper will automatically exit the programming mode.
This is a general step-by-step guide for remotes, varying from version to version. You should check the user manual to get the exact procedure for the task.
Why would the remote stop working?
Viper remotes can stop working if the car goes into valet mode. This can be because of the random pressing of the buttons. You can find a button on the remote to disable garage mode.
Why is my car remote not working sometimes?
Car remotes can be less responsive if they have old batteries inside them. Replace the old battery with a new one, which should be fine.
Why is my car remote not working after the battery change?
This can be because there are loose connections in the start system or the car is incompatible with this remote.
Conclusion
If the Viper remote is not working as it should be, you must go through every possible place where a problem can occur. Car remotes are relatively easy to troubleshoot, then why spend hundreds of bucks getting professional help? Check the above-mentioned reasons properly and your remote should be fine again.
