Having trouble with your Lexus remote start not working? You’re not alone.
Many Lexus owners face this issue. It can be frustrating, especially on cold mornings. Understanding why your remote start fails can save you time and stress. It may be a simple fix or something more complex. In this blog post, we will explore common reasons why your Lexus remote start might not work.
From battery problems to software glitches, we’ll cover all the bases. This guide will help you troubleshoot and possibly fix the issue. Let’s get started and get your Lexus running smoothly again.
Common Issues
Experiencing problems with your Lexus remote start can be frustrating. There are many reasons why your remote start might not work. Identifying common issues can help you fix the problem quickly. Let’s dive into two common issues: Battery Problems and Signal Interference.
Battery Problems
One of the most frequent issues is battery problems. The key fob battery might be dead or low. This can prevent the remote start from working. Check the battery level in your key fob. Replace it if needed. Also, ensure the car battery is charged. A weak car battery can also affect the remote start.
Signal Interference
Signal interference is another common issue. Devices like mobile phones, Wi-Fi routers, or other electronics can interfere. This interference can block the signal between your key fob and the car. Try to use the remote start away from these devices. Also, metal objects can cause interference. Avoid using the remote start near metal structures or heavy machinery.

Basic Checks
Experiencing issues with your Lexus remote start not working can be frustrating. Before seeking professional help, perform some basic checks. These simple steps often resolve common problems.
Key Fob Battery
First, check the battery in your key fob. A weak or dead battery can prevent the remote start from working. Replace the battery and try again. Use a high-quality battery to ensure long-lasting performance.
Range Limitations
Next, consider the range of your key fob. Remote starts have a limited range. Ensure you are within the specified range of your vehicle. Check your owner’s manual for details on the effective range.
Software Glitches
Many Lexus owners experience issues with the remote start feature. One common cause is software glitches. These glitches can disrupt the communication between your key fob and the vehicle. This results in the remote start not working as expected. Addressing these glitches involves two main approaches.
System Updates
Keeping your Lexus software up to date is crucial. Software updates often include fixes for known issues, including remote start problems. Follow these steps to check for updates:
- Turn on your vehicle’s ignition.
- Navigate to the settings menu on the infotainment screen.
- Select “System Updates” or “Software Updates”.
- Follow the on-screen instructions to install any available updates.
Regular updates can prevent many software-related issues. Make sure to check for updates periodically.
Reprogramming Key Fob
If updating the system does not resolve the issue, reprogramming the key fob might help. This process involves resetting the key fob’s connection to your vehicle. Here’s a simple guide:
- Sit inside your Lexus with the doors closed.
- Insert the key into the ignition and turn it to the “On” position without starting the engine.
- Press and hold the “Lock” and “Unlock” buttons on the key fob for about 15 seconds.
- Release the buttons and turn off the ignition.
- Test the remote start function to see if it works.
Reprogramming the key fob can often resolve connectivity issues caused by software glitches. If the problem persists, consulting a Lexus dealership might be necessary.

Faulty Components
When your Lexus remote start is not working, it could be due to various faulty components. Two critical components to check are the starter relay and the remote start module. Understanding these components can help you troubleshoot the issue effectively.
Starter Relay
The starter relay is a vital component in the remote start system. It acts as a switch, sending power to the starter motor. If the relay fails, the remote start will not function.
Here are some signs of a faulty starter relay:
- No response when you press the remote start button.
- Clicking sound from the relay area.
- Intermittent starting issues.
Testing the relay with a multimeter can confirm if it’s working. If not, replacing the relay might solve the problem.
Remote Start Module
The remote start module receives signals from your key fob. It then triggers the vehicle to start. A malfunctioning module means no remote start.
Common symptoms of a faulty remote start module include:
- Remote start works sporadically.
- Key fob buttons are unresponsive.
- Error codes on the dashboard.
Checking the module for loose connections can sometimes fix the issue. If not, the module may need replacement.
By focusing on these two components, you can often resolve remote start problems in your Lexus. Proper diagnosis and timely replacement of these parts ensure a reliable remote start system.
Environmental Factors
Experiencing issues with your Lexus remote start can be frustrating. Often, the problem is not with your vehicle but with the environment. Various environmental factors can affect the functionality of your remote start. Let’s explore some of the most common factors.
Extreme Temperatures
Extreme temperatures can impact your Lexus remote start’s performance. Both hot and cold weather can cause issues. In very cold weather, your car’s battery might not perform well. This can prevent the remote start from working.
On the other hand, extreme heat can cause the remote start system to malfunction. High temperatures can affect the electronic components. This can lead to a failure in the remote start system.
Obstructions
Obstructions between your remote and the vehicle can hinder the remote start’s functionality. Buildings, trees, or even other vehicles can block the signal. This makes it hard for the remote start to work properly.
Ensure there are no large objects between you and your car. Also, keep in mind that using the remote start from inside a building might reduce its effectiveness. Try stepping outside and using it again.
