What remote start does on your 2018 Ford Explorer Interceptor

Remote start lets you turn on your engine from outside the vehicle using a key fob or, on some models, a smartphone app. On a 2018 Ford Explorer Interceptor, pressing and holding the remote start button on your key fob will crank the engine and run it for about 15 minutes before shutting off automatically. The car does not shift into gear — it stays in Park — so the engine runs but the vehicle stays stationary.

This feature is useful on cold mornings when you want the engine and cabin to warm up before you get in, or on hot days when you want the air conditioning running before you sit down. The 2018 Interceptor came with this feature built in if your vehicle was ordered with the remote start package, though not all Interceptors included it as standard.

Key Takeaways

  • Remote start on the 2018 Ford Explorer Interceptor activates by holding the lock button on your key fob, then holding the remote start button (usually marked with an engine symbol) for about three seconds.
  • The engine runs for approximately 15 minutes before shutting off on its own, and the vehicle remains in Park with doors locked during this time.
  • Your key fob must be within range of the vehicle, typically 80 to 100 feet, for remote start to work.
  • If your Interceptor did not come with remote start from the factory, aftermarket remote start systems can be installed by a Ford dealer or may have access to automotive technician.
  • Remote start will not function if your doors are unlocked, the hood is open, or the parking brake is not set.

How to use remote start on your key fob

To start your 2018 Ford Explorer Interceptor remotely, first make sure you are within range of the vehicle — typically 80 to 100 feet depending on obstacles and interference. Press and hold the lock button on your key fob until the lights flash once, which confirms the doors are locked. Then when ready press and hold the remote start button (marked with an engine or circular arrow symbol) for about three seconds until the parking lights flash and the engine turns over.

The engine will run for 15 minutes and then shut off automatically. If you want to extend the runtime, you can press the remote start button again while the engine is running, which will add another 15-minute cycle. To stop the engine before the timer expires, press the lock button on your key fob.

When remote start will not work

Remote start has built-in safety features that prevent the engine from starting in certain situations. If your doors are unlocked, the hood is open, the parking brake is not set, or the transmission is not in Park, remote start will not function. The system is designed this way to prevent accidental movement or damage.

If you press the remote start button and nothing happens, check that all doors are closed and locked, the parking brake is engaged, and the hood is fully shut. If the key fob battery is low, remote start range will decrease significantly or stop working entirely. Replacing the key fob battery (usually a CR2032 or similar coin cell) often solves the problem.

Factory remote start versus aftermarket installation

The 2018 Ford Explorer Interceptor came with factory remote start if it was ordered with that option package. Factory systems are integrated into the vehicle's computer and key fob from the manufacturer, so they work seamlessly with all other vehicle systems and require no additional setup.

If your Interceptor did not come with remote start, you can have an aftermarket system installed by a Ford dealer or an independent automotive technician who specializes in remote start. Aftermarket systems vary in features and price, and installation typically takes a few hours. Some aftermarket systems use a separate fob or a smartphone app instead of your existing key fob, so ask the installer what options are available for your specific vehicle.

Smartphone app remote start

Some 2018 Ford Explorer Interceptors equipped with the FordPass Connect modem can use the FordPass mobile app to start the engine remotely from anywhere with a cellular connection, not just within key fob range. This feature requires a FordPass account and an active subscription to the connected services plan.

To use app-based remote start, open the FordPass app on your smartphone, select your vehicle, and tap the remote start button. The engine will start and run for 15 minutes just as it does with the key fob. Not all 2018 Interceptors have this capability — it depends on whether the vehicle was equipped with the connected services modem at the factory. You can check your vehicle's features in the FordPass app or contact a Ford dealer to confirm whether your Interceptor supports this feature.

Troubleshooting remote start problems

If remote start worked before but has stopped working, the most common cause is a dead or dying key fob battery. Open the key fob case (usually by sliding a small button or prying gently with a coin) and replace the battery with a fresh one of the same type. If that does not solve the problem, try reprogramming your key fob by sitting in the driver's seat with the doors closed, inserting your key in the ignition, and turning it to the On position without starting the engine, then back to Off, repeating this cycle several times until the lights flash.

If remote start still does not work after replacing the battery and reprogramming, the issue may be with the vehicle's remote start module or receiver. A Ford dealer can diagnose the problem using diagnostic equipment and repair or replace the faulty component. If you have an aftermarket remote start system, contact the installer or the system manufacturer for troubleshooting steps specific to that brand.

Frequently Asked Questions

Can I remote start my 2018 Ford Explorer Interceptor if the windows are down?

No. Remote start will not function if any doors or windows are unlocked or open. All doors must be closed and locked, and the windows must be fully closed. This safety feature prevents the vehicle from starting in an unsafe condition.

Does remote start drain my battery?

Running the engine for 15 minutes via remote start uses fuel and some battery power, but not enough to drain a healthy battery. If you use remote start multiple times per day in very cold weather, you may notice a slight drain over time, but a properly functioning battery should handle normal remote start use without issue.

What is the range of remote start on a 2018 Interceptor?

The key fob remote start range is typically 80 to 100 feet in open space, though obstacles like buildings, trees, and metal structures can reduce this distance. If you have FordPass app remote start, there is no distance limit as long as you have a cellular connection.

Can I remote start my Interceptor while it is parked in a garage?

Remote start will work in a garage as long as the key fob is in range and all safety conditions are met. However, running an engine in an enclosed space produces carbon monoxide, which is dangerous. Never remote start your vehicle in a closed garage or any enclosed space without proper ventilation.

Will remote start work if my Interceptor is in the shop for service?

It depends on the service being performed. If the technician has the keys and the vehicle is in a service bay, remote start may not work if the hood is open or the doors are unlocked for maintenance. Once service is complete and the vehicle is secured, remote start should function normally again.
