When the key fob will not start your SUV, the cause may be a weak fob battery, an unmet safety condition, or a vehicle fault. Searches for “Chevy Equinox remote start not working” often lead to generic advice, but the right check depends on what happens when you press the buttons.
This guide explains the normal starting sequence, common reasons the system stays off, and safe checks you can make at home. It also shows when a warning light or repeated failure calls for a technician.
Why Is Your Chevy Equinox Remote Start Not Working?
The Equinox remote-start system checks the vehicle and the key fob before it starts the engine. If a required condition is missing, the system may ignore the request or start and then shut the engine off.
Remote-start features and button sequences can vary by model year, trim, and equipment. Check your owner’s manual for the instructions that match your specific Equinox.
- No response from the vehicle: Check the fob battery, button sequence, range, and vehicle battery.
- Lights flash, but the engine does not start: Look for an open door, hood issue, warning light, or other lockout condition.
- The engine starts and stops: Check whether the vehicle detects a fault or the remote-start run period has ended.
- One fob works and another does not: The problem likely involves the fob, its battery, or its programming.
Notice the lights, horn, and dashboard messages when you try the feature. Those clues can help separate a fob problem from a vehicle-side lockout.
How Remote Start Works on an Equinox
On equipped models, the factory remote-start function usually uses the key fob to send a coded request to the vehicle. The vehicle starts only when its security system and operating conditions allow it.
Many compatible fobs use a lock-then-remote-start sequence, often by pressing the lock button and then holding the remote-start button. Button symbols and timing differ, so follow the sequence printed in the manual rather than relying on a sequence for another model year.
Some Equinox models also support remote commands through the myChevrolet app, depending on vehicle equipment, connectivity, and an active service plan. App access and available features can change, so check the current app and your vehicle’s account details.
Remote start typically runs the engine for a limited period and may allow a second start request. It does not replace the normal key or push-button procedure required to drive away. The vehicle may require you to enter, apply the brake, and switch the ignition on before shifting out of Park.
Common Causes and What They Usually Mean
A failed start request does not always mean a part has broken. The remote-start system can refuse to run because of a simple operating condition or a stored warning.
Use the table to match the symptom with a sensible first check. Exact indicators and feature behavior vary by year, so confirm details in the owner’s manual.
| What You Notice | Possible Cause | First Check |
|---|---|---|
| No lights or response | Weak fob battery, wrong sequence, excessive distance, or low vehicle battery | Try the spare fob nearby and replace the fob battery if needed |
| Lights flash, but no start | Door, hood, or liftgate not fully closed; vehicle lockout | Close each entry point firmly and check the dashboard for a message |
| Starts, then shuts off | Run time ended, warning condition, or an engine fault | Check the timing and look for warning lights or messages |
| Only one remote fails | Dead battery, damaged fob, or lost programming | Test the other remote and inspect the affected fob |
| Neither fob nor app works | Vehicle battery, system fault, or service/connectivity issue | Check the vehicle’s starting performance and app status |
Check the Remote-Start Requirements First
The Equinox may block a remote start when it detects a condition that could make starting unsafe or unreliable. A quick walk-around can catch several common causes before you test the fob again.
Check these items in order. If the vehicle displays a warning, use the message and the manual to guide the next step instead of repeatedly sending start requests.
- Confirm the vehicle is locked. Some factory systems require a lock command before the start request.
- Close every entry point. Check the hood, doors, and liftgate. A faulty hood-ajar switch can report an open hood even when it looks closed.
- Put the transmission in Park. Remote start generally will not run if the vehicle does not confirm Park.
- Check the fuel level. Some vehicles disable remote start when fuel is low. Consult the manual for your model’s exact threshold.
- Look for warning lights. A check-engine light or another fault may prevent remote starting on some model years.
- Check for an active security or theft deterrent alert. Resolve any displayed issue before trying again.
- Move closer to the vehicle. Walls, other vehicles, and radio interference can reduce fob range.
Do not test remote start in an enclosed garage. Exhaust gases contain carbon monoxide, which can cause serious injury or death. Keep the Equinox outdoors and away from people, pets, and flammable materials while checking the feature.
Test the Key Fob and Replace Its Battery
A weak fob battery often causes short range or inconsistent commands. The fob may still lock the doors while failing to send a reliable remote-start request, so working door locks do not rule out a battery problem.
Try the spare fob first if you have one. If the spare works from the same location, the original fob likely needs a new battery or further inspection.
Replace the Battery Carefully
Check the owner’s manual or the markings inside the fob for the correct battery type. Many fobs use a coin-cell battery, but the size can vary by remote and model year.
- Use the release notch or key blade slot identified in the manual to open the fob.
- Note the old battery’s orientation before removing it.
- Install the specified replacement with the positive and negative sides facing the correct way.
- Press the fob halves together and test the lock and remote-start buttons near the vehicle.
Avoid forcing the case apart or touching the circuit board more than necessary. If the fob has water damage, cracked buttons, or corrosion, a new battery may not solve the problem.
After replacement, most fobs work without a special reset, but procedures can vary. If the remote still fails while another fob works, ask a Chevrolet dealer or qualified automotive locksmith to check the fob and its programming.
Check the Vehicle Battery and Starting System
A weak 12-volt battery can interfere with remote functions, especially in cold weather or after the vehicle has sat unused. The Equinox may also struggle to start normally, show dim lights, or display electrical warnings.
Compare remote-start behavior with a regular start. If the engine cranks slowly, clicks, or does not start with the key or start button, focus on the vehicle battery and starting system rather than the fob.
You can inspect the battery terminals for looseness or visible corrosion, but avoid touching both terminals with a tool. Use the procedure in the owner’s manual for jump-starting, or call roadside assistance if you are unsure.
A battery test at an auto-parts shop or repair facility can help identify a weak battery. If the battery tests well but the vehicle has repeated electrical problems, a technician can check charging output, connections, and stored fault codes.
Try the App and Check Vehicle Settings
If your Equinox supports connected remote commands, the myChevrolet app can help determine whether the fob is the only issue. App commands need a compatible vehicle, an active connection, and the required account or service access.
If the app reports that the vehicle is unavailable, check the phone’s data connection and the app’s sign-in status. Also confirm the vehicle has cellular service where it is parked, since underground garages and remote areas can block a signal.
Check the vehicle settings and owner’s manual for remote-start options. Some settings may affect comfort features, such as climate control, while a dealer or vehicle configuration may affect whether remote start is available at all.
If the app cannot connect but the key fob works, the issue may involve the phone, account, service, or vehicle connectivity. If neither method works, investigate vehicle-side conditions or have the system scanned.
What to Do When the Engine Starts and Shuts Off
An Equinox that starts briefly and then stops may have reached its programmed run limit, or the system may have detected a fault. Check how long the engine ran and whether a message or warning light appeared.
Many factory systems turn the engine off after a set interval. Some allow a second remote-start request to extend the total run period, but the limit and button sequence depend on the vehicle.
If the engine stops after only a few seconds, try a normal start and watch the instrument panel. A check-engine light, security message, or other warning can point to a system that needs diagnosis.
Do not keep repeating remote-start commands when the engine starts and stalls. Repeated attempts will not fix a sensor, fuel, ignition, or security problem, and they can make symptoms harder to describe. Record the warning message and how long the engine runs.
When a Fuse, Hood Switch, or Module Needs Attention
A blown fuse, faulty hood-ajar switch, damaged wiring, or control-module problem can stop remote start even when the fob works. These faults need more careful testing than a battery or settings check.
Use the fuse diagram for your exact model year to identify any related fuse. Never replace a fuse with a higher-rated one, and do not assume a fuse is the cause just because the system stopped working.
A hood switch deserves attention when the dashboard reports that the hood is open despite a secure latch. The switch helps prevent the engine from starting while someone works under the hood, so bypassing it creates a safety risk.
Technicians can use a scan tool to read body-control and powertrain codes, inspect live data, and test the remote-start request. A basic code reader may not access every body or security module, so a no-code result does not always rule out a fault.
When to Contact a Dealer or Repair Shop
Arrange professional diagnosis if the Equinox displays a persistent warning, fails to start normally, or has problems with both remotes after basic checks. A shop can test the battery, inspect the hood switch and wiring, and scan relevant modules.
A Chevrolet dealer can also confirm equipment by VIN and check for applicable service information or software updates. Independent repair shops with suitable diagnostic equipment may perform many of the same tests.
Bring both fobs if possible and describe exactly what happens after each button press. Note whether the lights flash, whether the vehicle responds to the app, and whether any message appears on the dashboard.
Ask the shop to explain the test results before authorizing parts. Replacing a fob, switch, or module without confirming the fault can add cost without fixing the underlying problem.
How to Prevent Remote-Start Problems
Good fob and battery care can reduce avoidable failures. These habits will not prevent every electrical fault, but they can help you spot a developing problem early.
- Replace the fob battery when range drops or button response becomes inconsistent.
- Keep the fob dry and avoid storing it where the buttons can get pressed repeatedly.
- Close the hood, doors, and liftgate firmly before sending a start request.
- Follow the maintenance schedule for the vehicle’s 12-volt battery and charging system.
- Use the app and fob instructions for your model year, not a generic sequence for another Equinox.
- Address warning lights and recurring electrical messages promptly.
If the vehicle sits for long periods, check its battery condition before cold weather. A weak battery can cause starting and accessory issues even when the remote itself works correctly.
Frequently Asked Questions
Why Does My Equinox Remote Start Work Sometimes?
Intermittent operation often points to a weak fob battery, limited signal range, or a condition that changes between attempts. Check whether the hood, doors, and liftgate close fully, then test from closer to the vehicle. If the issue continues with both fobs, have the vehicle battery and stored fault codes checked.
Can a Check-Engine Light Stop Remote Start on a Chevy Equinox?
Yes, some Equinox model years disable remote start when the check-engine light or another fault is active. The rule can vary by year and fault, so check the owner’s manual and read the diagnostic codes. Do not clear a warning without finding out why it appeared.
How Do I Know If My Equinox Key Fob Battery Is Weak?
Shorter range, delayed response, or inconsistent operation can signal a weak battery. The fob may still lock or unlock the doors while remote start fails. Test a spare remote if available, then replace the battery with the type listed for your fob.
Will Disconnecting the Battery Reset Remote Start?
Disconnecting the vehicle battery is not a reliable first fix. It may erase settings or create new electrical issues, and it will not repair a failed fob, hood switch, or module. Check the manual and have the fault diagnosed before disconnecting the battery.
Can I Add Remote Start to an Equinox That Does Not Have It?
Availability depends on the model year, trim, factory equipment, and compatible parts. A Chevrolet dealer can check the vehicle by VIN and explain approved options. Before buying an aftermarket kit, confirm compatibility with the vehicle’s security and electrical systems.
Get Your Equinox Remote Start Working Again
Start with the fob battery, correct button sequence, vehicle locks, and dashboard warnings. Then compare the fob with the app or spare remote, if equipped.
If normal starting also fails, or warning messages remain, have the battery and vehicle systems tested. A scan and targeted inspection can identify a switch, wiring, or module fault without relying on guesswork.
