Remote start is a feature on many newer vehicles that allows the owner to start the car from a distance, usually using a key fob or a smartphone app. This can be a convenient way to warm up the car in the winter or cool it down in the summer before getting in. However, sometimes remote start may not work, which can be frustrating for the owner.
There are a number of reasons why remote start may not be working. One possibility is that the key fob battery is dead or weak. Another possibility is that there is a problem with the remote start system itself. This could be a problem with the wiring, the module, or the antenna. Finally, it is also possible that there is a problem with the car’s security system.
If you are having trouble with your remote start, there are a few things you can do to troubleshoot the problem. First, try replacing the key fob battery. If that does not work, you can try resetting the remote start system. To do this, consult your vehicle’s owner’s manual. If you are still having problems, you may need to take your car to a mechanic to have the remote start system diagnosed and repaired.
1. Dead or weak key fob battery
A dead or weak key fob battery is one of the most common reasons why remote start may not be working. The key fob battery is responsible for powering the remote start transmitter, and if the battery is dead or weak, the transmitter will not be able to send a signal to the car to start it.

2. Problem with the remote start system
A problem with the remote start system is one of the most common reasons why remote start may not be working. The remote start system is responsible for receiving the signal from the key fob and sending it to the car’s engine control unit (ECU), which then starts the car. If there is a problem with any component of the remote start system, it can prevent the car from starting.
There are a number of things that can cause a problem with the remote start system, including:
- Faulty wiring
- Damaged module
- Faulty antenna
If you are having trouble with your remote start, it is important to have the system diagnosed by a qualified technician. The technician will be able to identify the problem and repair it.
Here are some real-life examples of how a problem with the remote start system can cause remote start not to work:
- In one case, a customer’s remote start was not working because the wiring harness had become damaged. The technician was able to repair the wiring harness and the remote start began working again.
- In another case, a customer’s remote start was not working because the module had failed. The technician was able to replace the module and the remote start began working again.
Understanding the connection between a problem with the remote start system and remote start not working is important because it can help you troubleshoot the problem and get your car started. If you are having trouble with your remote start, it is important to have the system diagnosed by a qualified technician.
3. Problem with the car’s security system
A problem with the car’s security system is another common reason why remote start may not be working. The security system is designed to prevent unauthorized access to the vehicle, and it can do this by disabling the remote start system. If there is a problem with any component of the security system, it can prevent the remote start system from working.
There are a number of things that can cause a problem with the car’s security system, including:
- Faulty sensors
- Damaged wiring
- Faulty control module
If you are having trouble with your remote start, it is important to have the security system diagnosed by a qualified technician. The technician will be able to identify the problem and repair it.
Here are some real-life examples of how a problem with the car’s security system can cause remote start not to work:
- In one case, a customer’s remote start was not working because the hood sensor was faulty. The technician was able to replace the hood sensor and the remote start began working again.
- In another case, a customer’s remote start was not working because the wiring harness had become damaged. The technician was able to repair the wiring harness and the remote start began working again.
Understanding the connection between a problem with the car’s security system and remote start not working is important because it can help you troubleshoot the problem and get your car started. If you are having trouble with your remote start, it is important to have the security system diagnosed by a qualified technician.
4. Interference from other electronic devices
Remote start systems use radio waves to communicate with the car’s engine control unit (ECU). Other electronic devices, such as cell phones, garage door openers, and even other vehicles, can emit radio waves that interfere with the remote start signal. This interference can prevent the remote start system from sending a signal to the ECU, which will prevent the car from starting.
The strength of the interference will depend on a number of factors, including the power of the interfering device, the distance between the device and the car, and the frequency of the radio waves being emitted. In some cases, even a weak signal can be enough to interfere with the remote start system. Here are some real-life examples of how interference from other electronic devices can cause remote start not to work:
- One customer’s remote start was not working because their cell phone was too close to the car. When they moved their cell phone away from the car, the remote start began working again.
- Another customer’s remote start was not working because their garage door opener was emitting a strong radio signal. When they turned off the garage door opener, the remote start began working again.
Understanding the connection between interference from other electronic devices and remote start not working is important because it can help you troubleshoot the problem and get your car started. If you are having trouble with your remote start, try moving any potential sources of interference away from the car and see if that solves the problem.
5. Extreme weather conditions
Remote start systems are designed to work in a variety of weather conditions, but extreme weather conditions can sometimes interfere with their operation. For example, very cold temperatures can cause the car’s battery to lose power, which can prevent the remote start system from working. Similarly, very hot temperatures can cause the remote start system’s electronic components to overheat, which can also prevent it from working.
In addition, snow, ice, and rain can block the remote start system’s antenna, which can prevent it from receiving the signal from the key fob. Here are some real-life examples of how extreme weather conditions can cause remote start not to work:
- One customer’s remote start did not work on a very cold day because the car’s battery had lost power. When the customer jumped the battery, the remote start began working again.
- Another customer’s remote start did not work on a very hot day because the remote start system’s electronic components had overheated. When the customer allowed the car to cool down, the remote start began working again.
- Another customer lives in an area that gets a lot of snow and ice. Their remote start often doesn’t work after a snow or ice storm because the antenna is blocked. When the customer clears the snow and ice from the antenna, the remote start begins working again.
Understanding the connection between extreme weather conditions and remote start not working is important because it can help you troubleshoot the problem and get your car started. If you are having trouble with your remote start, check the weather conditions and see if they may be a factor. If the weather conditions are extreme, you may need to use a different method to start your car, such as using the key.
