When your Kia remote start stops working, it can be really frustrating. The good news is that this is usually an easy fix. Most Kia remote start problems happen because of a dead key fob battery, signal interference, or the car’s computer system needs attention.
You might see error messages about a low car battery or notice the remote start working only sometimes. Don’t worry – we’ll walk you through the common causes and show you exactly how to get your remote start working again.
Overview of Kia Remote Start
The Kia remote start system lets you start your car’s engine and control climate settings from a distance using your key fob or smartphone app. This convenient feature helps prepare your car before you get in.
Understanding Remote Start Feature
Your Kia’s remote start works through a wireless signal sent from your key fob or the Kia Connect app to your vehicle. The signal tells your car to start the engine and run for up to 10 minutes.
To use remote start, you’ll need to press the lock button first, then hold down the remote start button for about 2-3 seconds. Your car’s lights will flash to confirm the command was received.
The remote start system has built-in safety features like checking that all doors are closed and the hood is shut before starting.
Benefits of Remote Start
Remote start lets you warm up your car in winter or cool it down in summer before getting in. The climate control system activates automatically when you remote start.
You can start your Kia from inside your home or office, saving time during your morning routine. This feature is especially helpful in extreme weather.
Remote start through the Kia Connect app lets you control your car’s climate settings from anywhere using your phone. You can turn on the heat, AC, or defrost remotely.
The system also provides peace of mind by letting you verify your car is locked and secure from a distance.
Common Issues with Kia Remote Start
Your Kia remote start can stop working for several common reasons. The good news is that many of these problems have simple fixes you can try at home.
Key Fob Battery Problems
A dead or weak battery is the most frequent cause of remote start failure. Your key fob needs enough power to send a strong signal to your car.
Watch for these warning signs of a dying battery:
- Remote works only when very close to the car
- Need to press buttons multiple times
- LED light on remote is dim or doesn’t light up
Replacing the battery is easy and cheap. Most Kia key fobs use CR2032 batteries you can buy at any hardware store.
Physical Damage to Remote
Dropping your key fob or getting it wet can damage internal components. Look for these signs of damage:
- Cracked or broken casing
- Loose or sticky buttons
- Water spots inside the fob
- Bent or misaligned parts
Small cracks might let moisture in and cause corrosion. If you spot visible damage, you may need a new key fob from your Kia dealer.
Faulty Wiring or Connection
Problems with your car’s electrical system can prevent remote start from working. Bad connections often develop over time.
Signs of wiring issues include:
- Remote start works intermittently
- Car starts but immediately shuts off
- Strange electrical behavior in other systems
A professional needs to check the wiring and connections if you suspect electrical problems.
Range Limitations
Your remote start has a maximum working distance. Try these tips to get the best range:
- Point the remote straight at your car
- Hold the fob up high near your head
- Move away from buildings or large objects
- Replace the battery if range suddenly decreases
Most Kia remote starts work up to 30-50 feet away in ideal conditions. Metal and concrete structures can reduce this range significantly.
Troubleshooting Kia Remote Start Problems
When your Kia’s remote start stops working, a few simple checks can often solve the problem. The most common issues are related to the key fob, safety features, or system errors.
Initial Troubleshooting Steps
First, check if your car doors, hood, and trunk are completely closed. These must be secure for the remote start to work properly.
Make sure your car has enough fuel and the check engine light isn’t on. These safety features can prevent remote starting.
Try standing closer to your vehicle. The remote start range can be affected by distance and obstacles.
Double-check that your car isn’t already running. The remote start won’t work if the engine is on.
Assessing the Key Fob and Battery
Look at your key fob for any visible damage or worn buttons. Physical damage can stop it from working correctly.
Replace the key fob battery if it’s more than 2 years old. A weak battery is a common cause of remote start failure.
Test the other buttons on your key fob. If none work, you likely need a new battery.
Clean the key fob buttons with a cotton swab and rubbing alcohol. Dirt can interfere with button function.
Checking Remote Commands Reception
Press the lock button twice before using remote start. Your Kia needs to be locked for remote start to work.
Listen for the horn sound when you try remote start. Different horn patterns can help diagnose specific problems.
Watch for flashing lights when sending commands. No response could mean the car isn’t receiving the signal.
Try your spare key fob if you have one. This helps determine if the problem is with the fob or the car.
Consulting the User Manual
Find the remote start section in your manual. Each Kia model has specific starting procedures.
Look up any error codes or horn patterns in the troubleshooting guide. These often point to exact problems.
Check if your subscription to Kia Connect services is active. Some remote features need a valid subscription.
Review the safety requirements listed in your manual. Missing any requirement will prevent remote start from working.
Maintenance and Care for Remote Start
Taking good care of your Kia remote start system helps prevent issues and extends its lifespan. Regular maintenance and professional service keep your remote start reliable.
Regular Key Fob Maintenance
Replace your key fob battery every 12-18 months to maintain strong signal strength. Dead batteries are a common cause of remote start failures.
Keep your key fob clean and protected from damage. Use a soft cloth to wipe off dirt and avoid exposing it to extreme temperatures or moisture.
Store your spare key fob in a safe place at room temperature. Don’t leave fobs in hot cars or cold garages.
Check the key fob buttons regularly for wear and tear. If buttons feel sticky or unresponsive, clean them gently with electronics cleaner.
System Updates and Dealer Services
Schedule yearly remote start system inspections at your Kia dealer. They can test signal strength and diagnose potential issues early.
Ask about available software updates for your remote start module. Updates can improve performance and fix known bugs.
Keep your remote start warranty information and manual handy. Note when services are performed and any issues that arise.
If you notice reduced range or inconsistent operation, have a Kia technician check the antenna and wiring connections.
