Why is my remote start not starting my car?
Remote start systems are a convenient feature that allows you to start your car from a distance, especially during cold mornings or hot afternoons. However, when your remote start fails to work, it can be frustrating and inconvenient. At Kevin's Autos, with years of experience in car maintenance and repair, we’ve seen this issue many times. Below, we’ll explore the common reasons why your remote start might not be working and what you can do about it.
1. Dead or Weak Key Fob Battery
The most common reason for a remote start failure is a dead or weak battery in your key fob. If the battery is low, the signal from the remote may not reach your car. Replacing the battery is a simple fix that often resolves the issue.
2. Car Battery Issues
Your car’s battery plays a crucial role in the remote start system. If the battery is weak or dead, the remote start won’t function. Check your car battery and ensure it has enough charge. If it’s old or showing signs of wear, it might be time for a replacement.
3. Faulty Hood Sensor
Most remote start systems include a hood sensor as a safety feature to prevent the car from starting while the hood is open. If this sensor is faulty or misaligned, it can prevent the remote start from working. Inspect the hood sensor and ensure it’s functioning properly.
4. Engine or System Warning Lights
If your car has an active warning light, such as a check engine light, the remote start system may be disabled as a precaution. Addressing the underlying issue causing the warning light is necessary to restore remote start functionality.
5. Transmission Not in Park
Remote start systems are designed to work only when the car is in park. If your transmission is not fully in the park position, the system will not activate. Double-check that your car is securely in park before attempting to use the remote start.
6. Programming or Signal Issues
Sometimes, the remote start system may lose its programming or experience signal interference. Reprogramming the remote or consulting your car’s manual for troubleshooting steps can help resolve this issue.
7. Aftermarket System Malfunctions
If your remote start system was installed as an aftermarket feature, it might not be integrated perfectly with your car’s systems. Wiring issues or compatibility problems can cause malfunctions. In such cases, it’s best to consult a professional technician.
What Should You Do Next?
If your remote start isn’t working, here are some steps you can take:
- Replace the key fob battery and try again.
- Check your car battery and ensure it’s fully charged.
- Inspect the hood sensor for any damage or misalignment.
- Address any active warning lights by consulting a mechanic.
- Ensure your car is in park before using the remote start.
- Reprogram the remote or consult your car’s manual for troubleshooting tips.
- If you have an aftermarket system, have it inspected by a professional.

Frequently Asked Questions
Can the remote key cause the car not to start?
Your car not starting could be the result of many different issues. On the heavier side of the potential causes, it could be total engine failure (not ideal). But on the lighter and more common side, it could have something to do with the key fob (which is still annoying, but typically much easier to deal with).
Why won't my key fob start my car anymore?
This is usually a sign the battery is running low and needs to be replaced, so start by replacing the battery. It is always easier to do this while the remote is still working. If this doesn't solve the problem, it may be due to interference with another vehicle or a faulty transmitter.
Can a key fob cause your car not to start?
A dead battery in your key fob means it can't broadcast the signal the ignition system is looking for. If your car or truck can't detect the correct signal, then the ignition will remain locked, and you won't be able to start your car with the fob in your pocket.
Why is my car not starting with remote start?
A dead battery, faulty starter, and an activated valet mode are some of the reasons why your remote start isn't working. Aside from electrical issues, coolant and oil pressure problems can also affect the remote start's operation. It costs between $250 and $400 to replace a damaged remote start fob.
Why isn't my car responding to my key fob?
The most common issue is the battery running out of charge and needing to be replaced. In most cases, a car key fob will last many years, but if it is used more frequently then you could end up having to buy one. This can easily be done at a local garage, tech shop or by yourself at home.
Where is remote reset button?
Reset the remote: If the remote still isn't working, you can try resetting it. Look for a small reset button on the back of the remote or inside the battery compartment. Use a paperclip or a similar object to press and hold the reset button for a few seconds. Then, try pairing the remote with the TV again.
Why would my automatic start stop working?
Start/stop can be unavailable for a lot of reasons. Engine temp too low, battery temp too low, fuel level too low, driving in stop and go traffic, your belt not being buckled, etc.
Can a remote start preventing car from starting?
No because the remote start only operates the starter and energizes the ignition system. It doesn't affect the engine once it's started. If you have a misfire, your CEL should be on. Read its code as it will tell you which cylinder(s) to check.
How do I reset my remote start?
Press the Lock button on your remote car starter. Within five seconds of turning it on, turn your key back to the “off” position (or press the start button again). Repeat the on-off cycle three more times—you'll do four in total.
How do I get my remote starter to work again?
Does LOCK/UNLOCK work?
- Check/replace remote batteries. If your remote has USB port, plug it into a USB charger and then try again later.
- Check the remote antenna inside of your vehicle. Make sure that the connecting harness is fully secured.
- Try reprogramming your remotes.
