A remote start that worked yesterday can leave you facing a cold or hot cabin today. If you have a Chevy Colorado remote start not working, a weak key-fob battery, a vehicle setting, or a safety condition may be stopping the system.
This guide explains how the factory system works, what to check first, and when to seek a scan or repair. You will also learn how model-year differences affect the process and what to do if the engine starts but shuts off quickly.
How the Chevy Colorado Remote Start System Works
Factory remote start lets you start the engine from outside the truck using the key fob. On many Colorados, you press the lock button and then hold the remote-start button, but the button layout and sequence can vary by year and equipment.
The truck checks several conditions before it allows the engine to start. It can refuse the command when a warning, low fuel level, open door, or other system status conflicts with its safety rules.
- Look for a circular-arrow remote-start symbol on the key fob.
- Check the owner’s manual for the exact button sequence for your model year.
- Confirm that your truck has factory remote start or a compatible dealer-installed system.
- Note whether the truck gives a light flash, horn response, or dashboard message after the command.
Some newer Colorado models may support remote commands through connected services, depending on the truck’s equipment and active service plan. App features and service terms can change, so check the current Chevrolet app and your vehicle’s manual for details.
Why Chevy Colorado Remote Start Not Working Can Have Several Causes
A remote-start failure does not always mean the starter or engine has failed. The key fob may not reach the truck, or the vehicle may be blocking the command because it detects a condition that needs attention.
Start with checks that do not require tools. A quick look at the fob, doors, dashboard warnings, and fuel level can help narrow the cause before you replace parts.
- The fob battery is weak: The locks may still work at close range even when the remote-start signal does not reach reliably.
- The command sequence is incorrect: Pressing buttons too slowly or in the wrong order can prevent activation.
- A door, hood, or tailgate is not fully closed: The truck may cancel remote start if it detects an open entry point.
- A warning or fault is active: An illuminated check-engine light or another fault may block remote starting, depending on the model.
- The truck needs a reset or diagnosis: A control module, antenna, wiring, or aftermarket accessory may interfere with normal operation.
Use the truck’s response as a clue. No response often points toward the fob, range, or command sequence, while a brief start followed by a stop suggests a different set of checks.
Checks to Make Before Replacing Parts
Rule out simple causes before buying a battery or scheduling a repair. Park outside, stand near the truck, and try the documented sequence once with all doors and the hood fully shut.
Make a note of what happens each time. Repeating the command many times can make it harder to tell whether the truck has a consistent fault or a signal-range problem.
- Confirm the fob supports remote start. Check for the remote-start symbol and compare the fob with the manual’s description.
- Lock the truck first if the manual requires it. Then press and hold the remote-start button for the time stated in the manual.
- Move closer to the truck. Test from a clear spot near the driver’s door, away from walls or large metal objects.
- Close every entry point. Check the hood, doors, and tailgate, and make sure the truck sits in Park.
- Check the instrument panel. Look for warning lights or messages that appeared before the remote-start attempt.
- Try the spare fob, if available. If one fob works and the other does not, the problem likely involves the faulty fob or its battery.
If the truck starts with one fob but not the other, avoid replacing vehicle parts until you test the fob battery and buttons. A fob can also suffer damage from moisture or a drop, even when its case looks intact.
How to Fix a Weak Key-Fob Battery or Signal Problem
A weak fob battery is one of the easiest causes to check. The correct coin-cell type varies by fob, so read the number printed on the old battery or check the owner’s manual before buying a replacement.
Replace the cell carefully. Keep the battery away from children, follow the fob’s polarity markings, and avoid touching the flat battery surfaces more than needed.
- Open the fob using the method shown in the manual or on the fob case.
- Remove the old cell and note which side faces up.
- Install a fresh battery of the same type with the correct polarity.
- Close the fob fully and test the locks and remote-start command near the truck.
If the locks work only at very close range, the battery may still be weak or the fob may have an internal fault. If a fresh battery does not help, compare the spare fob or ask a dealer or qualified automotive locksmith to test the transmitter.
Radio interference can also shorten the fob’s range. Test in a different parking spot, away from dense buildings, other transmitters, or equipment that may interfere with the signal.
Check Vehicle Conditions That Block Remote Starting
The Colorado’s remote-start controls depend on the vehicle being in a safe state. The exact limits vary by year, engine, and equipment, so use the owner’s manual for your specific truck rather than relying on a rule from another model.
Check these common conditions before seeking a repair. Correct any visible issue and try the command again once.
- Fuel level: Some models block remote start when fuel is low.
- Warning lights: A check-engine light or other active fault may prevent the system from starting.
- Entry points: Make sure the hood, doors, and tailgate are fully closed.
- Gear selection: The truck must be in Park, with the ignition and shift controls in the required state.
- Remote-start limit: Many systems limit consecutive remote-start cycles. Starting the truck with the key may restore the function.
- Temperature or battery status: Vehicle protection logic can block operation when the truck detects a condition that needs attention.
Do not ignore a dashboard warning just to make remote start work. If a warning remains after you correct an obvious issue, have the truck scanned for diagnostic trouble codes.
What to Do If the Engine Starts and Then Shuts Off
If the Colorado starts remotely but stops soon after, the fob has probably sent a valid command. The truck may be detecting a fault, or a required step may be missing when you enter the cabin.
Observe how long the engine runs and whether a message appears. Some factory systems stop the engine when a driver does not enter and turn the ignition on within the time stated in the manual.
- Unlock the truck and enter promptly after remote starting.
- Follow the manual’s instructions for taking control of the ignition.
- Check for a check-engine light or a message displayed after the engine stops.
- Notice whether the shutdown happens every time or only in certain weather or locations.
If the engine stops almost immediately on every attempt, schedule a diagnosis instead of repeatedly restarting it. A technician can check stored codes and determine whether a sensor, ignition, fuel, or control-system issue is involved.
When a Reset or Professional Diagnosis Makes Sense
A basic retry can help after a temporary signal issue, but disconnecting the battery is not a guaranteed fix. Battery disconnection can erase settings or create new warning lights, and it may not correct the underlying fault.
Try a simple reset only when the owner’s manual recommends it. If you recently installed an alarm, remote starter, dash camera, or other electrical accessory, mention that when you book service.
Try a Safe Restart of the System
Park the truck, switch it off, remove the key or move the fob away as directed by the manual, and wait briefly before trying the normal sequence again. This simple pause can help rule out a temporary interruption without changing vehicle settings.
Do not pull fuses at random or disconnect wiring to force the system to respond. A wrong fuse or connector can disable other vehicle functions and complicate diagnosis.
Ask for a Scan When the Problem Persists
A repair shop can scan the truck’s control modules for faults related to the body control module, security system, hood switch, or remote-start circuit. A basic code reader may not access every module, so a scan tool with Chevrolet-compatible coverage can provide more useful information.
Ask the technician to check the fob signal, vehicle battery condition, relevant fuses, and any aftermarket equipment. Provide the model year, engine, trim, symptoms, and any recent repairs.
How Model Year and Equipment Affect the Fix
Remote-start features and controls can differ across Colorado generations. A key fob, connected app, dealer-installed system, or aftermarket kit may use different operating steps and troubleshooting methods.
Use the manual for your model year and verify the truck’s equipment before ordering parts. A replacement fob or remote-start module must match the vehicle’s configuration and may require programming.
| System Type | What to Check | Best Next Step |
|---|---|---|
| Factory key-fob remote start | Button sequence, battery, range, warnings | Follow the owner’s manual and test a spare fob |
| Connected-services app | Account access, service status, phone connection | Check current app prompts and vehicle eligibility |
| Dealer-installed system | System-specific fob and programming | Contact the installing dealer |
| Aftermarket system | Installer instructions, wiring, add-on modules | Ask the installer to inspect the system |
Chevrolet’s owner materials and service information provide the most reliable guidance for the exact year and equipment. Connected-service availability can change, so confirm current terms with Chevrolet rather than assuming an older subscription or app feature still applies.
When to Stop Troubleshooting at Home
Stop testing and arrange service if the truck shows a persistent warning, has damaged wiring, or behaves unpredictably after an electrical repair. A remote-start fault can sometimes point to a broader vehicle problem.
Seek help sooner if you notice any of these signs:
- The engine cranks unusually or fails to start with the key.
- The security light stays on or the truck will not recognize either fob.
- A fuse blows again after replacement.
- The remote starter activates without a clear command.
- You smell fuel, see smoke, or notice damaged electrical wiring.
For safety, do not work under the hood while the engine is running or reach near belts and fans. Keep the truck outdoors during remote-start tests, and follow the manual’s instructions for parking and exhaust clearance.
Frequently Asked Questions
Can a Low Truck Battery Stop Remote Start?
Yes. A weak vehicle battery can keep the truck from meeting the electrical conditions needed to start, even if the fob works. If the engine cranks slowly, the lights dim, or the truck has trouble starting normally, have the battery and charging system tested before focusing on the remote-start module.
Why Does My Colorado Remote Start Work Only Sometimes?
Intermittent operation often points to a weak fob battery, limited signal range, radio interference, or a vehicle condition that changes between attempts. Test close to the truck, try a spare fob, and check for warning messages. If the pattern continues, a module scan can reveal stored faults.
Will Remote Start Work If the Check-Engine Light Is On?
It may not. Some Colorado configurations block remote starting when the truck detects an engine or system fault, and the exact response depends on the model year and fault. Read the dashboard message and have the trouble code checked rather than clearing the warning without finding its cause.
Can I Add Remote Start to a Colorado That Did Not Come with It?
Some trucks can accept a compatible Chevrolet accessory or aftermarket system, but compatibility depends on the year, trim, and existing equipment. Ask a Chevrolet dealer or qualified installer to confirm the correct kit and programming. Avoid buying a universal fob before confirming that it works with your truck.
How Many Times Can I Remote Start My Colorado?
Many factory systems limit the number of consecutive remote-start cycles before you must start the truck normally. The limit and reset method can vary by model year. Check the owner’s manual for your Colorado, then use the ignition as directed before trying remote start again.
Get Your Colorado Remote Start Working Again
Start with the fob battery, range, button sequence, and vehicle safety conditions. If the truck still refuses the command, or starts and shuts off, check its warning messages and arrange a scan for relevant faults.
Use the manual for your specific model year, especially before replacing a fob or changing electrical parts. That approach helps separate a simple battery or setup issue from a problem that needs professional diagnosis.
