Why is my Ford Explorer remote start not working?
In most cases, remote start failure comes down to a simple issue like a dead key fob battery, unmet safety conditions, or a connectivity/subscription problem with FordPass. A quick check of the basics typically reveals the culprit.
Common causes and quick checks
Before diving into deeper diagnostics, review these frequent reasons remote start might fail on a Ford Explorer. This list covers what homeowners can verify quickly at home.
- Key fob battery is dead or weak, preventing the car from recognizing the remote signal.
- Vehicle is not in the correct state for remote start (doors, hood, and trunk must be closed; gear must be in Park; ignition must be off).
- Vehicle battery is low or the 12V system is weak, which can block remote start from engaging.
- Remote start feature is disabled in the vehicle’s settings or by the dealer (factory or after-market restrictions).
- Remote start via FordPass requires FordPass Connect (the in-car modem) and an active subscription or trial; connectivity issues can block app-based starts.
- Security/immobilizer or alarm fault may prevent remote starting for safety reasons.
- Key fob or phone-based remote start isn’t pairing correctly due to a recent reset, replacement, or software update.
If you’ve ruled out these common causes, you can proceed to more targeted troubleshooting or consult a dealership for a diagnostic check.
Troubleshooting with FordPass and vehicle settings
When the problem lies with connectivity, app access, or vehicle configuration, these steps help determine whether the issue is user-facing or systemic. A prepared owner can often fix or clarify the situation without a visit to the dealer.
- Confirm FordPass Connect is active in your vehicle and that any trial or subscription for remote start is current.
- Check your mobile device’s data connection and ensure FordPass is up to date; verify that the vehicle shows online status in the app.
- Make sure you have the correct vehicle selected in the FordPass app and that you are attempting a start within the allowed time window and safety constraints.
- Verify you are using the proper remote-start method (via the key fob or FordPass) as described in your owner’s manual, and ensure the doors are locked and the vehicle is in Park before initiating.
- If you recently replaced the key fob battery or paired a new device, re-pairing the fob or re-linking FordPass to the vehicle may be required.
If these app-based steps do not resolve the issue, the problem may be related to the vehicle’s telematics module or a deeper software fault that warrants professional service.
Other considerations and when to seek help
Some failure modes require professional service, especially when the issue seems to persist across both fob and app methods or when warning lights appear on the dashboard. These scenarios may indicate hardware or software faults that need dealer diagnostics.
When to contact a dealer or certified technician
Contact a Ford service center if you notice persistent remote-start failure after performing the basic checks and app troubleshooting. Possible next steps include a telematics module reset, reprogramming the keys, or a software update to the vehicle’s infotainment/remote-start system.
Summary
Most Ford Explorer remote-start problems boil down to a dead or weak key fob battery, unmet safety conditions (doors closed, gear in Park, etc.), a low 12V battery, or a connectivity/subscription issue with FordPass Connect. Start with quick at-home checks, verify app connectivity and subscriptions, and re-pair devices if needed. If problems persist, a dealership diagnostic can identify deeper hardware or software faults.
