Remote start is a fantastic feature, especially during scorching summers or frigid winters. The ability to pre-condition your car’s interior before even stepping inside offers unparalleled comfort and convenience. But what if you’re unsure whether your key fob is equipped with this coveted function? This comprehensive guide will walk you through the various ways to determine if your key fob boasts remote start capabilities.
Examining Your Key Fob for Visual Clues
The first and often simplest step involves a close inspection of your key fob itself. Automakers frequently indicate remote start functionality through distinct button markings. Look for specific symbols or labels that suggest the feature’s presence.
Deciphering the Symbols
The most common symbol associated with remote start is a circular arrow, often resembling a chasing arrow or a partially completed circle. This icon usually signifies the ability to remotely activate the engine. Keep a sharp eye out for this distinctive marking.
Another potential symbol is a “x2” or similar notation alongside the lock button. This indicates that pressing the lock button twice initiates the remote start sequence. Some manufacturers might even use a dedicated “Start” button marked with text, making the feature unmistakably clear.
Finally, look for a key icon with a wave or sound wave signal emanating from it. This also suggests remote start, especially if the key icon is paired with another button.
Button Combinations and Sequences
Sometimes, remote start isn’t activated by a single, dedicated button but rather a combination of buttons pressed in a specific sequence. For example, some vehicles require you to press the lock button followed by the remote start button, or the lock button twice followed by the remote start button. Refer to your vehicle’s owner’s manual for the correct sequence if you suspect this is the case.
Consulting Your Vehicle’s Owner’s Manual
Your vehicle’s owner’s manual is an invaluable resource for understanding all the features and functions of your car, including remote start. This document provides detailed explanations, diagrams, and instructions on how to operate various systems.
Locating the Remote Start Section
Within the owner’s manual, search for keywords like “remote start,” “remote engine start,” or “key fob functions.” The index is usually the best place to begin your search. Once you locate the relevant section, carefully read the instructions and diagrams.
Understanding the Operating Procedures
The manual will outline the precise steps required to activate remote start using your key fob. It will also detail any limitations, such as the maximum run time, conditions that prevent remote starting (e.g., low fuel, open hood), and the range of the key fob. Familiarize yourself with these operating procedures and limitations for safe and effective use.
Checking Your Vehicle’s Window Sticker (Monroney Label)
The window sticker, also known as the Monroney label, provides a comprehensive list of your vehicle’s features and options. This sticker is typically affixed to the car’s window at the dealership. While it might not be available for used vehicles, it’s an excellent source of information if you have access to it.
Finding the “Optional Equipment” Section
Scan the window sticker for the “Optional Equipment” section. This section lists all the features added to the vehicle beyond the base model. Look for entries such as “Remote Start System,” “Remote Engine Start,” or similar phrases.
Deciphering Option Codes
Sometimes, the window sticker uses option codes instead of descriptive text. These codes can be confusing, but they represent specific features and packages. Consult a vehicle information database or contact the dealership to decode any unfamiliar option codes.
Contacting Your Dealership or Manufacturer
If you’ve exhausted the previous methods and are still unsure about your key fob’s remote start capabilities, reaching out to your dealership or the vehicle manufacturer directly is a viable option. They can provide definitive answers based on your vehicle’s VIN (Vehicle Identification Number).
Providing Your VIN
The VIN is a unique 17-digit alphanumeric code that identifies your specific vehicle. It’s typically located on the driver’s side dashboard near the windshield, on the driver’s side doorjamb, or on your vehicle’s registration and insurance documents. Provide your VIN to the dealership or manufacturer so they can access your vehicle’s build sheet.
Requesting a Build Sheet
The build sheet is a detailed record of all the features and options included in your vehicle when it was manufactured. The dealership or manufacturer can access this information using your VIN. Ask them to check if remote start was included as a factory-installed option.
Observing Your Vehicle’s Behavior
While not foolproof, observing your vehicle’s behavior after attempting to use remote start can provide clues. If the car starts when you press a particular button or sequence, it’s a strong indication that the feature is present.
Testing Potential Remote Start Sequences
Experiment with different button combinations on your key fob. For example, try pressing the lock button twice followed by another button. Observe whether the vehicle’s parking lights flash, the horn honks, or the engine starts. Be mindful of local noise ordinances when testing the horn.
Looking for Confirmation Signals
Many vehicles provide visual or audible confirmation when remote start is successfully activated. This may include flashing parking lights, a brief horn chirp, or an illuminated icon on the dashboard. Pay attention to any signals that indicate remote start functionality.
Aftermarket Remote Start Systems
If your vehicle didn’t come with factory-installed remote start, it’s still possible to add this feature through an aftermarket system. These systems are installed by professional technicians and can be controlled using a separate key fob or integrated with your existing key fob.
Identifying Aftermarket Installations
Look for signs of aftermarket installations, such as an additional antenna on the windshield, a separate control module under the dashboard, or a different-looking key fob specifically for remote start. A professional mechanic can help identify aftermarket systems.
Checking the Aftermarket System’s Documentation
If you suspect an aftermarket remote start system is installed, try to locate the system’s documentation or contact the installer. This documentation will provide instructions on how to operate the system and identify its features.
Potential Reasons Remote Start Might Not Work
Even if your vehicle is equipped with remote start, several factors can prevent it from functioning properly. Understanding these potential issues can help you troubleshoot the system.
Low Battery in Key Fob
A weak battery in your key fob can significantly reduce its range and prevent it from transmitting the remote start signal effectively. Try replacing the battery in your key fob with a fresh one to rule out this issue.
Low Fuel Level
Many vehicles are programmed to disable remote start when the fuel level is low to prevent the engine from running out of gas while unattended. Ensure your fuel tank is adequately filled before attempting to use remote start.
Open Hood, Trunk, or Doors
For safety reasons, remote start is typically disabled if any of the vehicle’s doors, hood, or trunk are open. Make sure all entry points are securely closed before attempting to remote start your vehicle.
Check Engine Light
A lit check engine light indicates a problem with the vehicle’s engine or emissions system. In many cases, this will disable remote start to prevent further damage. Address any check engine light issues before attempting to use remote start.
System Malfunctions
Like any electronic system, remote start can experience malfunctions. This could be due to faulty wiring, a defective control module, or other issues. If you suspect a system malfunction, consult a qualified mechanic for diagnosis and repair.
Key Takeaways
Determining whether your key fob has remote start requires a systematic approach. Start with a thorough visual inspection of the key fob, consulting your vehicle’s owner’s manual, and checking the window sticker (if available). If these steps are inconclusive, contact your dealership or the vehicle manufacturer for definitive confirmation. Understanding potential reasons why remote start might not work can also help you troubleshoot any issues. Remember that aftermarket systems exist, and observing your vehicle’s behavior can provide clues about remote start functionality. By following these guidelines, you can confidently determine whether your key fob is equipped with this convenient feature and ensure its proper operation.
How can I identify the remote start button on my key fob?
The easiest way to identify a remote start button is to look for a button with a circular arrow symbol. This symbol often depicts an arrow making a full or partial circle, sometimes with the word “Start” printed alongside it. Other possible symbols include a key with an asterisk (*) or a button labeled “Remote Start” directly.
If you’re unsure, consult your vehicle’s owner’s manual. It should contain detailed diagrams and descriptions of all key fob buttons and their functions, including the remote start feature if your vehicle is equipped with it. The manual will clearly show the button’s location and label, removing any guesswork.
My key fob has a circular arrow button, but the car doesn’t start when I press it. Why?
Several factors can prevent your remote start from functioning even with the correct button. First, ensure that your vehicle is in “Park” (for automatic transmissions) or neutral (for manual transmissions) with the parking brake engaged. Many systems have safety interlocks that prevent remote start if these conditions aren’t met. Also, check if any warning lights are illuminated on your dashboard, such as the check engine light. Remote start is often disabled if there are underlying mechanical issues.
Secondly, the key fob battery might be weak or dead. Try replacing the battery with a fresh one and attempt the remote start again. Another common reason is that the vehicle’s hood or trunk might be slightly ajar. Most systems have sensors that disable remote start if any of these are not fully closed and latched.
Is remote start standard on all vehicles with keyless entry?
No, remote start is not a standard feature on all vehicles with keyless entry. Keyless entry simply allows you to unlock and lock your car doors without physically using a key. Remote start is a separate, optional feature that needs to be specifically included in the vehicle’s configuration.
While keyless entry is becoming increasingly common, remote start remains an add-on feature in many models or is only available on higher trim levels. It’s essential to check your vehicle’s specifications to determine if it includes the remote start functionality, regardless of whether it has keyless entry.
How do I know if my car has remote start if I don’t have the key fob?
If you don’t have the key fob, you can check your vehicle’s original window sticker or the build sheet. These documents list all the factory-installed features and options included in your car when it was purchased. Look for line items like “Remote Start System,” “Remote Engine Start,” or similar phrases.
Alternatively, you can contact the vehicle manufacturer’s customer service department with your Vehicle Identification Number (VIN). They can access the vehicle’s information in their database and provide you with a list of all its original features, including whether or not it was equipped with remote start.
Can I add remote start to my car if it didn’t come with it originally?
Yes, it is often possible to add remote start to a car that didn’t originally come with it. There are aftermarket remote start systems available that can be installed by a professional. These systems typically involve wiring into the vehicle’s electrical system and may require programming the key fob or installing a new one.
However, it’s crucial to ensure that the aftermarket system is compatible with your specific vehicle make and model. Improper installation can lead to electrical issues or damage to the vehicle’s computer system. It is highly recommended to have the installation performed by a qualified and experienced automotive technician.
