This article will discuss in full detail all the common reasons behind your Hyundai remote start not working. We’ll also share helpful tips on what to do if this happens, why your remote only work sometimes, why your remote won’t work after changing batteries, and so on.
Why your Hyundai remote start is not working
Your Hyundai remote start feature is highly convenient. But if it fails to work, it can be quite frustrating. Knowing what causes it to fail is the first step to helping you deal with it.

Below are all the common causes behind a non-working Hyundai remote start:
Dead key fob or car battery
One of the likely reasons for your remote start not working is a dead battery. A weak or dead battery means the key fob can’t send a single to the starter, thus it won’t respond and your car won’t start.
Besides the key fob battery, you may also want to check whether your main car battery is dead. This is because it will also make the remote start fail to work.
Solution: Replace your key fob battery and try restarting your car. If the battery was the issue, your remote start should start working again.
If the main car battery is weak or dead, you’ll need to recharge or replace it as necessary. Jump-starting your car can help recharge it. But in cases where the battery is completely dead, replacing it is the best solution.
Remote start is disabled
Yes, some people also tend to make the mistake of trying to use this function without first making sure it’s activated or they’re using the correct procedure. The car keys should also not be inside the car and you should turn off your car via key fob or app.

Solution: Check your owner’s manual for the correct procedure for starting your vehicle remotely. And keep in mind that the procedure may vary between different Hyundai models, so what works for one vehicle doesn’t always work for the other one.
Vehicle security system is on
Your Hyundai remote system may also stop working if your vehicle security system is activated or if the immobilizer system is malfunctioning.
Note that these are security measures put in place to help prevent unauthorized access to your vehicle.
Solution: Check whether your vehicle security system is disarmed. Moreover, check whether your immobilizer system is functioning correctly.
You can always refer to your user manual for more info on how to reset/reprogram your car immobilizer or security system when necessary.
If you’re unable to fix this issue, seek professional assistance from your Hyundai dealership or a reliable mechanic.
Distance factor
Most people don’t know this but your Hyundai remote start functionality usually has a limited range. Therefore, if you’re attempting to remote start your car when you’re far away from it, the signal may fail to reach it, and it may then fail to work.
Solution: You should try moving closer to your car and try to activate the remote start feature again. Check your owner manual for the specific range for this remote function and be sure you’re within this range.
Your doors, hood, or tailgate are open
In most cases, Hyundai remote start may fail to start if your hood, doors, and even the tailgate are open. This is simply a safety feature that helps prevent the car from starting/moving if there’s someone near the car when the engine is running.
Solution: make sure all your vehicle doors, tailgate, and hood are fully closed and locked. If you find any of these parts are open, close them correctly and then try remote starting your car.
However, this may not apply to Hyundai models, so you may want to consult your user manual just to be sure.
Vehicle system issues
Another reason why your vehicle may fail to work is due to issues with your vehicle system or sensors.
Some cars may have issues such as software glitches, faulty components, wiring issues, etc., that may keep your remote system from working.
For instance, a malfunctioning vehicle system and sensor may affect your remote start. A check engine light usually shows there’s an issue with your car.
Still at it, issues with the fuel system, starter, or ignition system may also make it impossible for your car to start remotely.

Solution: Try scanning your vehicle computer for stored error codes that could give you a clue on what the underlying issue is and whether it’s likely to affect your vehicle functionality.
Also, check your owner’s manual for known issues that could interfere with your car start feature.
Alternatively, you can simply visit your local Hyundai dealership or qualified mechanic to have them diagnose all the potential issues related to your remote start and fix them.
Your car is in park mode
If your Hyundai remote start fails to work, you may also want to check whether your car is in the park or neutral mode. Usually, the remote start requires that your vehicle be set to either of these two modes to allow remote starter starting of the engine.
Solution: Put your car in parking or neutral mode and then retry the remote start function. You may also want to consult your user manual for the correct procedure for using the remote start function in your car.
Damaged remote transmitter/receiver
Sometimes your remote transmitter or receiver may become damaged or fail over time. When this happens, signal transmission between your key fob and your car will be affected.
Solution: Have your remote transmitter/receiver diagnosed by a qualified auto technician or authorized Hyundai dealership and fixed or replaced as necessary.
Remote start system interference
Environmental factors or electronic devices can easily interfere with your remote start. Radiofrequency from power lines as well as other vehicles or even household appliances are notorious for disrupting the communication between your car and key fob.

Solution: Move to a different location where there are no potential sources of interference. Avoid areas with strong radio signals or high-power electrical lines. Ensure there are no electronic devices near your key fob that may interfere with its signal transmission.
You don’t have an active BlueLink subscription
Some Hyundai car models require you to have an active BlueLink subscription to be able to use the remote start feature.
If your car has this type of requirement, then the remote start feature won’t work until you have an active subscription.
Solution: Check your BlueLink subscription and ensure it’s active before you try using the remote start feature again.
