This issue is common and frustrating for many SRX owners. Imagine it’s a cold morning, and you want to warm up your car. You press the remote start button, but nothing happens. This small feature can make a big difference in comfort and convenience.
Whether it’s a dead battery, a malfunctioning key fob, or a more complex issue, there are several reasons why your remote start might fail. Understanding these can save you time and money. In this blog, we’ll explore the common causes and solutions to get your Cadillac SRX remote start working again. Let’s dive in and troubleshoot this problem together.
Checking The Key Fob
Does your Cadillac SRX remote start not work? The key fob might be the cause. Checking the key fob can help you find the issue and fix it. Here are some steps to help you.
Battery Life
The key fob battery can lose power over time. A weak battery may not send a strong signal to your Cadillac SRX. Check the battery life by following these steps:
- Open the key fob using a small flat tool.
- Remove the old battery carefully.
- Check the battery type and buy a new one.
- Insert the new battery in the same position.
- Close the key fob and test it.
If the remote start works, the battery was the problem. Remember to use the correct battery type.
Signal Interference
Signal interference can affect the key fob’s performance. Many things can block the signal. Here are some common causes:
- Other electronic devices
- Metal objects
- Thick walls or structures
Move to an open area and try the remote start again. Keep the key fob away from other electronics. If it works, the signal was blocked.
If you still have issues, the key fob might need further inspection. Consider visiting a professional to check the key fob and car system.
Examining The Car Battery
If your Cadillac SRX remote start is not working, the car battery might be the issue. A weak or dead battery can prevent the remote start from functioning. Let’s look into some key aspects to examine the car battery.
Battery Voltage
First, check the battery voltage using a voltmeter. A fully charged battery should read around 12.6 volts or more. If the voltage is below 12.4 volts, the battery might be weak and need charging. Follow these steps:
- Turn off the car and remove the key.
- Connect the voltmeter to the battery terminals.
- Read the voltage on the display.
If the reading is low, recharge or replace the battery.
Corrosion And Connections
Next, inspect the battery terminals for corrosion and ensure all connections are secure. Corrosion can hinder the flow of electricity. Here’s how to check and clean:
- Open the hood and locate the battery.
- Look for white or greenish deposits on the terminals.
- If present, clean the corrosion with a mixture of baking soda and water.
- Use a wire brush to scrub the terminals gently.
- Reconnect the terminals tightly.
Ensure there are no loose or damaged wires. Secure connections are crucial for proper battery function.
By examining the battery voltage and checking for corrosion, you can ensure the battery is in good condition. This might solve the remote start issue in your Cadillac SRX.
Verifying The Remote Start System
Having trouble with your Cadillac SRX remote start not working? Let’s dive into the process of verifying the remote start system. This will ensure your remote start works smoothly and efficiently. Proper verification can save you time and frustration.
Activation Procedure
First, familiarize yourself with the correct activation procedure. Ensure your Cadillac SRX is in ‘Park’ and the doors are locked. Press and hold the remote start button on your key fob. Hold it for about four seconds. The vehicle should start if done correctly. If it doesn’t, repeat the steps.
Sometimes, the remote start may not activate due to an incorrect sequence. Check your owner’s manual for specific instructions. Following the right steps can make a big difference.
Programming Issues
Programming issues can also affect the remote start system. Your key fob might need reprogramming. This can happen if the battery was recently changed. Consult your owner’s manual for reprogramming instructions. You might need to visit a dealership for this.
Another programming issue could be related to the vehicle’s software. Sometimes, updates are needed. Check for any available software updates for your Cadillac SRX. These updates can fix bugs and improve system performance.
Ensuring your key fob and vehicle software are properly programmed is crucial. It can help resolve remote start problems effectively.

Inspecting The Hood Latch
When the remote start on your Cadillac SRX isn’t working, inspecting the hood latch is essential. The hood latch plays a key role in the remote start system. If the latch is not functioning correctly, the remote start feature may fail. In this section, we will explore the importance of the hood latch, how to check it, and some tips for maintenance.
Latch Sensor Functionality
The hood latch sensor detects if the hood is open or closed. If the sensor is faulty, it can send incorrect signals to the car’s computer. This can prevent the remote start from working. Make sure the hood is securely closed. Next, check the sensor for any visible damage or dirt. Clean the sensor with a soft cloth if needed.
Maintenance Tips
Regular maintenance of the hood latch can prevent issues. Lubricate the latch mechanism with a suitable lubricant. This ensures smooth operation. Check the alignment of the hood latch. Misalignment can cause the sensor to malfunction. Regularly inspect the sensor for dirt and debris. Keeping it clean ensures accurate readings.
Checking The Brake Pedal
The remote start feature on your Cadillac SRX is a great convenience. But it can be frustrating when it stops working. One common issue lies with the brake pedal. This post will guide you through the steps to check the brake pedal and get your remote start working again.
Brake Pedal Switch
The brake pedal switch is a key component. It tells the car’s system when you press the brake. If the switch is faulty, the car may think the brake is not engaged. This can prevent the remote start from working.
Here’s how to check the brake pedal switch:
- Locate the brake pedal switch near the top of the brake pedal arm.
- Press the brake pedal and see if the brake lights come on.
- If the lights do not come on, the switch may need adjustment or replacement.
Sensor Alignment
Proper sensor alignment is crucial for the brake pedal switch to function. Misalignment can cause the switch to send incorrect signals.
Follow these steps to check the sensor alignment:
- Inspect the position of the brake pedal switch.
- Ensure the switch makes contact with the brake pedal arm.
- If it is not aligned, adjust it by loosening the mounting screws and moving it into place.
- Tighten the screws once the switch is correctly positioned.
These steps should help you diagnose and fix issues with the brake pedal, ensuring your Cadillac SRX remote start works as expected.
