Troubleshooting Common Remote Start Problems
Remote start systems are a great convenience during Airdrie’s cold winters, allowing you to warm up your vehicle before you step outside. However, when the system fails to respond, it can be frustrating, especially on freezing mornings. Understanding how remote start systems work and knowing how to troubleshoot common issues can save you time and prevent unnecessary repairs.
This guide explains the most frequent causes of remote start failure, how to fix them, and when to seek professional help from experts like Tools in Motion in Airdrie.

Understanding How Remote Start Systems Work
Remote start systems let you start your vehicle from a distance so it’s ready to drive when you are. To troubleshoot effectively, it’s important to understand how they function.
Key Components of a Remote Start System
A remote start system includes several parts: the remote control or key fob, a receiver installed in the vehicle, and the ignition system. The remote sends a signal to the receiver, which activates the ignition and starts the engine. If the signal isn’t properly transmitted or received, the car won’t start.
Common Features and Benefits
Beyond starting your vehicle, many remote start systems integrate with car alarms and can control defrost settings and seat warmers. These features make them especially useful during Alberta winters, providing comfort and convenience before you even enter the vehicle.
Remote Start Not Working: Identifying the Problem
Remote start failure can happen for several reasons. Below are some of the most frequent issues and how to identify them.
Battery Issues in the Key Fob
A dead or weak key fob battery is one of the most common causes of remote start failure. If the battery is low, it may not send a strong enough signal to the vehicle. Replacing the battery usually solves the issue. The cost for a new battery typically ranges from $5 to $15.
Signal Interference
Signal interference can prevent communication between the remote and the car. Interference can come from nearby electronic devices or buildings in dense areas like downtown Calgary. Try standing closer to your vehicle or moving away from potential sources of interference to ensure the signal reaches the receiver properly.
Car Alarm Troubleshooting and Its Impact
Remote start systems are often linked to the vehicle’s alarm. A problem with one can affect the other.
Alarm System Malfunctions
An active car alarm can stop the remote start from working. Make sure the alarm is disarmed before starting the vehicle remotely. If the alarm seems faulty, check for blown fuses or malfunctioning sensors. Fuses are inexpensive, typically costing $5 to $10, though diagnosing the issue may require professional assistance.
Sensor Problems
Many vehicles include safety sensors that prevent remote start activation if certain conditions exist, such as the hood being open. Ensure that all doors, the trunk, and the hood are closed before using remote start. Regularly inspect sensors for dirt or ice buildup to avoid false readings.
Mechanical and Electrical Concerns
Sometimes, the issue lies within the vehicle rather than the remote start system itself.
Engine and Battery Health
If your vehicle struggles to start with a key, it may also have trouble with the remote start. Check that your car battery and engine are in good condition. Cold temperatures can make weak batteries fail more easily. A new car battery typically costs between $50 and $200. Regular maintenance helps prevent unexpected issues.
Wiring and Installation Issues
Improper installation or damaged wiring can cause the system to malfunction. If the system was recently installed or serviced, inspect for loose connections or wiring problems. Professional installation or repair, which usually costs between $100 and $500, ensures the system functions reliably.
Seasonal Considerations for Remote Starters
Remote starters are especially useful in winter, but they can also improve comfort year-round if properly maintained.
Winter Tips
Keep your vehicle’s battery in good condition during the cold months, as low temperatures reduce battery efficiency. Also, check that your heater and defroster settings are correct before using remote start.
Summer Adjustments
In warmer months, you can use your remote start to activate the air conditioning. Make sure your climate control settings are adjusted before leaving the car. Testing both heating and cooling systems before the seasons change helps prevent last-minute issues.
When to Seek Professional Help
While many remote start issues can be fixed with basic troubleshooting, some require professional attention.
Persistent Issues
If you’ve tried the steps above and your remote start still doesn’t work, consult a qualified technician. Persistent issues may indicate a deeper electrical or system fault. Diagnostic tests usually cost between $50 and $100 and can prevent more costly repairs later.
Upgrades and Replacements
If your remote start system is outdated or frequently malfunctions, consider upgrading. Tools in Motion in Airdrie offers expert installation and can recommend models suited to your vehicle and needs. Upgrades generally cost between $200 and $800, depending on the system’s features.
