How to Remotely Start Your Car: A Step-by-Step Guide

The process for remote starting a car is designed to be straightforward, yet it incorporates crucial safety checks to prevent accidental activation or theft. While specific button sequences can vary slightly between manufacturers and aftermarket systems, the fundamental principles remain consistent. Always refer to your system's owner's manual for precise instructions, but here's a general walkthrough:

Step 1: Ensure Vehicle Readiness

Before initiating a remote start, your vehicle must be in a safe and secure state. Most systems require the following conditions to be met:

• Vehicle in Park (P) or Neutral (N): For automatic transmissions, the gear selector must be firmly in 'Park'. For manual transmissions, more advanced systems might require a specific 'remote start ready' procedure, often involving leaving the car in neutral with the handbrake engaged before turning off the engine. This is a critical safety feature to prevent the car from lurching forward upon starting.
• All Doors, Bonnet, and Boot Closed: Sensors throughout your vehicle detect if any entry points are ajar. If a door, the bonnet, or the boot is not fully closed, the remote start function will typically be inhibited. This is a security measure to prevent the vehicle from starting if it's not fully secured.
• Handbrake Engaged: Even with automatic transmissions, engaging the handbrake (parking brake) is often a prerequisite for remote start. This adds an extra layer of security and stability.
• No Fault Codes or Warning Lights: If your car's dashboard is displaying critical warning lights (e.g., check engine light, low oil pressure), the remote start system may be programmed to prevent starting to protect the engine.

Step 2: Activating the Remote Start

Once your vehicle is ready, the next step involves using your remote control, or 'fob'.

• Locate the Remote Start Button: This is typically a dedicated button on your fob, often marked with an 'RS', a circular arrow, or a lightning bolt symbol. Some systems might integrate the start function with an existing button, such as the 'lock' button pressed multiple times.
• Press the Button Sequence: The most common activation methods include:
  • Pressing and holding the dedicated remote start button for 2-3 seconds.
  • Pressing the 'lock' button once, then pressing and holding the remote start button.
  • Pressing the 'lock' button three times in quick succession.
• Listen for Confirmation: After successfully initiating the remote start, your vehicle will usually provide visual and/or audible confirmation. This could be:
  • Flashing parking lights a certain number of times.
  • A quick chirp from the horn.
  • On more advanced Two-Way Communication systems, the remote fob itself might light up or vibrate to confirm the engine has started.

The engine will typically run for a pre-set duration, usually 10 or 15 minutes, before automatically shutting off if no one enters the vehicle. This is a safety and fuel-saving feature.

Step 3: Entering and Driving Your Vehicle After Remote Start

Once your car has started remotely, you cannot simply jump in and drive off. A 'handover' procedure is required to take control of the vehicle.

• Unlock the Doors: Use your remote fob to unlock the car doors as you normally would.
• Enter the Vehicle: Get into the driver's seat.
• Insert Key and Turn to 'ON' Position: For traditional key ignition systems, insert your physical key into the ignition barrel and turn it to the 'ON' position (not 'START', as the engine is already running).
• Press the Foot Brake: As soon as you press the foot brake, the vehicle's control will transfer from the remote start system to the ignition key. At this point, you are ready to select a gear and drive.

For vehicles with push-button start systems, the process is slightly different: you would typically enter the car with your smart key, press the foot brake, and then press the 'start' button once (without holding it) to transfer control.

How to Remotely Unlock Your Car

Unlocking your car with a remote start system is typically the same as unlocking it with a standard key fob, as the remote start functionality is an add-on to the vehicle's existing central locking system.

• Locate the Unlock Button: On your remote fob, there will be a dedicated 'unlock' button, usually depicted as an open padlock or simply labelled 'unlock'.
• Press the Unlock Button: A single press of this button will typically unlock all the car doors. Some systems might have a double-press feature to unlock only the driver's door first, then all doors on the second press.
• Listen/Look for Confirmation: The car's indicators will usually flash twice, and you might hear the central locking solenoids engage, confirming the doors are unlocked.

Many advanced remote start and security systems offer additional unlocking features:

• Power Boot Release: Some fobs include a separate button to pop open the boot (tailgate) remotely, a convenient feature when carrying shopping.
• Smartphone Convenience: The most cutting-edge systems allow you to unlock your car, and even start it, via a dedicated smartphone application. This offers virtually unlimited range, provided both your phone and the car have an internet connection. This is particularly useful if you're unsure if you locked your car or need to let someone in when you're not nearby.

Benefits of Using a Remote Start System

Beyond the simple convenience, remote start systems offer several practical advantages for UK motorists:

• Comfort in Extreme Weather: In winter, you can pre-warm your engine and cabin, defrosting windows and making the car comfortable before you even step outside. In summer, you can pre-cool the interior, especially beneficial for cars left in direct sunlight. This leads to a more pleasant driving experience from the moment you enter.
• Enhanced Engine Warm-Up: Allowing the engine to warm up gradually at idle can be beneficial, particularly in colder climates. It helps oil circulate effectively and brings engine components to optimal operating temperatures before being put under load. While modern engines are robust, a gentle warm-up is never a bad thing.
• Increased Security Features: Many remote start systems are integrated with comprehensive Security Features. These can include:
  • Glass Break Detection: Alarms triggered by the sound of breaking glass.
  • Backup Battery: Ensures the alarm system remains operational even if the main car battery is disconnected.
  • Vehicle Tilt Sensor: Detects if the car is being jacked up, useful against wheel theft or towing.
  • Flashing Parking Lights: Provides visual deterrent and alerts.
  • Smartphone Notifications: Alerts you directly to your phone if the alarm is triggered.

  These features, often part of an integrated package, provide a robust layer of protection against theft and vandalism.

  Common Issues and Troubleshooting

  While remote start systems are generally reliable, you might occasionally encounter issues. Here are some common problems and their potential solutions:

  Issue	Possible Cause	Solution
  Car won't remote start	Door, bonnet, or boot ajar	Ensure all entry points are fully closed and latched.
  	Vehicle not in Park/Handbrake not engaged	Verify the gear selector is firmly in 'Park' and the handbrake is engaged.
  	Low car battery voltage	Check car battery; jump-start if necessary. A weak battery might not provide enough power for the system.
  	Remote fob battery low/dead	Replace the battery in your remote fob.
  	Out of range	Move closer to the vehicle. Obstructions (buildings, other cars) can reduce range.
  	System in 'valet' mode	Check your system's manual to disable valet mode, which typically disables remote start.
  	Check engine light/Fault code active	Have the vehicle diagnosed by a mechanic to clear any critical fault codes.
  Remote unlock not working	Remote fob battery low/dead	Replace the battery in your remote fob.
  	Out of range	Move closer to the vehicle.
  	Vehicle battery dead	If the car battery is completely dead, central locking won't respond.
  System activates, but engine doesn't start	Fuel level too low	Some systems prevent remote start if the fuel tank is near empty.
  	Ignition wiring issue (professional diagnosis needed)	If all other checks fail, seek professional assistance.

  For persistent issues, it's always best to consult the installation manual for your specific remote start system or contact a professional automotive technician who specialises in these systems. Attempting complex repairs yourself could void warranties or cause further damage.

  

  Understanding Different Remote Start System Types

  Remote start technology comes in various forms, each offering different levels of functionality and range.

  • One-Way Systems: These are the most basic. You send a command (e.g., start, lock, unlock) to the car, and the car executes it. You don't receive confirmation back on your remote that the command was successful.
  • Two-Way Systems: These systems offer Two-Way Communication. The remote sends a command to the car, and the car sends a signal back to the remote to confirm the action (e.g., engine started, doors locked). This is incredibly useful for peace of mind, especially if your car is out of sight. The remote often has an LCD screen or LED indicators to display the car's status.
  • Smartphone Integrated Systems: These are the most advanced. They utilise cellular technology to allow you to control your car from virtually anywhere with mobile network coverage. Commands are sent via an app on your smartphone, and the car's status (locked, unlocked, running, battery voltage, GPS location) is displayed on your phone. These often come with a subscription service.

  Frequently Asked Questions (FAQs)

  Q: Can I drive off immediately after remote starting my car?

  A: No. As explained in the handover process, you must enter the vehicle, insert your key (or have your smart key present for push-button start), and typically press the foot brake to take control of the vehicle. This is a crucial safety feature.

  Q: Is remote starting bad for my car's engine?

  A: No, when used correctly, remote starting is not detrimental to your engine.
