You press the button on your key fob, expecting your Equinox to roar to life from the comfort of your home. Nothing happens. You try again. Still nothing. That sinking feeling hits because now you’ll have to walk out into the freezing cold or blazing heat to start your car manually.
Remote start failures on the Chevrolet Equinox can stem from simple battery issues to more complex electrical problems. Getting to the bottom of it doesn’t have to mean an expensive trip to the dealership. This guide walks you through everything you need to know about why your remote start stopped working and how to get it running again.
Understanding Remote Start Failures
Your Equinox’s remote start system is a clever network of components that talk to each other. When you press that button, your key fob sends a signal to the car’s receiver module. This module then checks a series of safety conditions before allowing the engine to start. If any single piece of this chain breaks down, your remote start won’t work.
The system won’t activate if it detects certain conditions. Your hood needs to be closed. The transmission must be in park. The hazard lights can’t be on. These built-in safety features protect you and your vehicle, but they can also prevent remote start from working when something seems off to the car’s computer.
Temperature extremes affect how well your remote start performs. Cold weather drains key fob batteries faster than you might expect. Heat can interfere with the radio frequency signals traveling between your fob and the car. Even parking too far away can create problems, especially if there are thick walls or other vehicles blocking the signal path.
What makes this issue particularly frustrating is how intermittent it can be. Your remote start might work perfectly one day and fail the next. This inconsistency often points to environmental factors or components that are on their way out but haven’t completely failed yet. Paying attention to patterns can help you pinpoint the real culprit.
Chevrolet Equinox Remote Start Not Working: Common Causes
Multiple factors can prevent your remote start from functioning properly. Some are quick fixes you can handle in minutes, while others require a bit more attention. Let’s look at what typically goes wrong.
1. Weak or Dead Key Fob Battery
Your key fob battery powers the signal that reaches your Equinox. Over time, these small batteries lose their charge. You might notice the remote start failing before other key fob functions stop working because remote start requires a stronger signal than simply unlocking the doors.
Most key fob batteries last between three to four years, but heavy use shortens this lifespan. If you use your remote start daily, especially in extreme temperatures, your battery drains faster. The good news is that key fob batteries are inexpensive and easy to replace.
A weak battery shows subtle signs before dying completely. Your remote start might work only when you’re very close to the vehicle. You may need to press the button multiple times to get a response. These are your early warnings that it’s time for a fresh battery.
2. Hood Pin Switch Problems
Your Equinox has a small switch under the hood that tells the system whether the hood is open or closed. This safety feature prevents the engine from starting when someone might be working under the hood. When this switch fails or gets stuck, your car thinks the hood is open even when it’s firmly closed.
Dirt, road salt, and corrosion commonly affect this switch. The hood pin switch sits in a vulnerable spot where it’s exposed to everything your tires kick up. Over time, the contacts can corrode or the mechanism can seize up.
3. Faulty Remote Start Module
The remote start module is the brain of the operation. This component receives signals from your key fob and coordinates with various vehicle systems to start your engine. When the module itself fails, no amount of button pressing will help.
Module failures often happen gradually. Your remote start might work sporadically at first, then stop working altogether. Electrical surges, water intrusion, or simple age can damage the module’s internal circuits. These modules are tucked away in your vehicle’s interior, usually behind the dashboard or under a seat.
4. Low Vehicle Battery Voltage
Your car battery needs sufficient charge to power the remote start system and crank the engine. Even if your battery has enough juice to run your radio or lights, it might not have the voltage needed for remote start. This system demands a strong, stable electrical supply.
Cold weather is especially hard on car batteries. The chemical reactions inside the battery slow down when temperatures drop, reducing available power. If your battery is older than three years, it might struggle to provide the consistent voltage your remote start system requires.
A battery on its last legs often shows warning signs. Your engine might crank slowly when you start it manually. Your headlights could dim when you first turn them on. These symptoms suggest your battery can’t maintain proper voltage, which directly impacts remote start functionality.
5. Signal Interference Issues
Radio frequency interference can block the signal between your key fob and your vehicle. Other electronic devices operating on similar frequencies can create noise that drowns out your key fob’s transmission. Parking garages with multiple wireless systems, areas near radio towers, or even some LED lighting can interfere with the signal.
Your parking location matters more than you might think. Concrete structures, metal buildings, and underground parking areas all weaken radio signals. If your remote start works fine in some locations but fails in others, signal interference is likely the culprit.
Chevrolet Equinox Remote Start Not Working: DIY Fixes
Fixing remote start issues often takes less time than you’d expect. Many solutions require nothing more than basic tools and a few minutes of your time. Here’s how to tackle each common problem.
1. Replace the Key Fob Battery
Pop open your key fob by finding the small slot where the two halves meet. Most Equinox key fobs use a flat screwdriver or a coin to pry them apart gently. Inside, you’ll see a small circular battery, typically a CR2032.
Note which side faces up before removing the old battery. The positive side usually has writing on it. Slide the old battery out and pop in the new one, making sure it’s oriented the same way. Snap the key fob back together and test your remote start.
If your remote start still doesn’t work after a battery change, try standing closer to your vehicle. The new battery needs a moment to sync properly. Some Equinox models require you to manually reprogram the key fob after a battery change, though most sync automatically.
2. Clean and Test the Hood Pin Switch
Open your hood and look for a small switch near the hood latch. This switch has a plunger that gets pressed when the hood closes. Spray the switch with electrical contact cleaner to remove any corrosion or debris that might prevent proper contact.
Press the plunger manually a few times to work the cleaner through the mechanism. Check if the plunger moves freely and springs back when released. If it’s sticky or doesn’t return to position, the switch needs replacement. You can test if this is your problem by manually holding the plunger down while someone tries the remote start.
3. Check Your Battery Voltage
Head to any auto parts store and ask for a free battery test. They’ll connect a tester that measures your battery’s voltage and overall health. Your battery should read at least 12.4 volts when the engine is off. Anything below 12 volts indicates a weak battery that needs charging or replacement.
If your battery tests low but isn’t completely dead, try charging it overnight with a battery charger. A full charge might restore enough power for your remote start to work again. Keep in mind that a battery that needs frequent charging is on borrowed time and should be replaced soon.
You can also test this yourself with a basic multimeter if you have one. Touch the red probe to the positive terminal and the black probe to the negative terminal. Check the reading with the engine off, then start the car manually and check again. The voltage should jump to around 13.7 to 14.7 volts when the engine runs, showing your alternator is charging properly.
4. Reset the Remote Start System
Sometimes the remote start system just needs a reset to clear any glitches. Start by manually starting your vehicle with the key. Let it run for about five minutes to ensure all systems are active and communicating properly. Turn off the engine and remove the key.
Wait two minutes before attempting the remote start again. This pause allows the vehicle’s computers to complete their shutdown sequence and reset. Try your remote start using the proper sequence for your model year. For most Equinox models, you press the lock button first, then immediately press and hold the circular arrow button until the turn signals flash.
5. Inspect Fuses and Connections
Your Equinox has two fuse boxes where you need to look. One sits under the hood near the battery, and another is inside the cabin, usually below the steering wheel. Your owner’s manual shows which fuses control the remote start system.
Pull out each relevant fuse and inspect it closely. The thin metal strip inside should be intact and continuous. If it’s broken or burned, replace it with a fuse of the exact same amperage. Never use a higher-rated fuse as a temporary fix because this can damage your electrical system.
Check the connections to your remote start module if you can access it. Wiggle the harness connectors to ensure they’re seated firmly. Corrosion on these connections can interrupt the signal flow. If you spot green or white crusty buildup, spray it with electrical contact cleaner and wipe it away gently.
6. Try the Backup Remote Start Method
Many newer Equinox models offer remote start through the myChevrolet mobile app. If your key fob remote start isn’t working, download the app and link your vehicle. This method bypasses the key fob entirely and might work even when your traditional remote start doesn’t.
The app connects to your vehicle through the OnStar system using cellular data. As long as your vehicle has an active OnStar subscription and cellular coverage, you can start your engine from anywhere. This also helps you determine if the problem is with your key fob or with the remote start system itself.
7. Contact a Certified Technician
If you’ve tried everything and your remote start still won’t cooperate, it’s time to call in professional help. A certified Chevrolet technician has diagnostic tools that can read error codes from your remote start module and pinpoint the exact failure point. Some issues, like a failed module or complex wiring problems, really do need expert attention and specialized equipment to fix properly.
Wrapping Up
Remote start problems on your Chevrolet Equinox don’t have to keep you stuck in uncomfortable weather. Most issues trace back to simple causes like a worn-out key fob battery or a dirty hood switch. Working through these fixes systematically usually gets your remote start back in action.
Start with the easiest solutions first and work your way through the list. You’ll likely find the problem before you reach the more complex repairs. Your mornings will be much more pleasant once that engine fires up from inside your house again.
