Experiencing issues with your Toyota key fob remote start can be frustrating, especially when you’re rushing to get going. If you’re finding that your Toyota key fob remote start is not working, you’re not alone. This is a fairly common problem, and thankfully, there are several potential causes and solutions you can explore before needing to visit a mechanic.
Before diving into complex issues, it’s crucial to understand how your Toyota’s remote start system is intended to function. For many Toyota models, particularly those from around 2018 onwards, remote start functionality can be linked to Toyota’s Remote Connect service. This service often comes with a trial period for new vehicles and may require a subscription to continue working after the trial expires. It’s important to note that availability and features can vary depending on your Toyota model and trim level. For instance, in 2018, Remote Connect was typically available on higher trims like XLE and XSE, but not on base models like LE or SE.
Let’s explore the common reasons why your Toyota key fob remote start might be failing and what you can do to address them.
Common Reasons for Toyota Key Fob Remote Start Failure
Several factors can contribute to a malfunctioning remote start system. Here are some of the most frequent culprits:
-
Expired Remote Connect Subscription: If your Toyota’s remote start is linked to the Remote Connect service, an expired subscription is a prime suspect. Toyota often includes a trial period for this service, and once it ends, features like remote start via the key fob may cease to function unless you renew the subscription. This is a common scenario, especially if you purchased a used Toyota and the previous owner had a subscription that has since lapsed.
-
Low Key Fob Battery: A weak battery in your key fob can significantly impact its signal strength and range. If the battery is too low, the fob may not be able to transmit the signal required to activate the remote start system in your Toyota.
-
Vehicle Battery Issues: Similar to the key fob battery, if your Toyota’s car battery is weak or not sufficiently charged, it can prevent the remote start system from engaging. The system requires adequate power to operate correctly.
-
System Glitches or Software Issues: Like any electronic system, your Toyota’s remote start can experience glitches or software malfunctions. These issues can sometimes arise after software updates or due to electrical fluctuations in the vehicle.
-
Hood or Door Ajar: For safety reasons, Toyota’s remote start system is designed not to activate if it detects that the hood, or any door, including the trunk, is not fully closed. Even a slightly ajar hood or door can prevent the remote start from working.
-
Check Engine Light or System Errors: If your Toyota’s check engine light is illuminated or there are other system error warnings on your dashboard, the remote start system may be disabled. This is a precautionary measure to prevent potential engine damage or other issues from being exacerbated by remote starting the vehicle.
-
Incorrect Remote Start Procedure: While it might sound simple, it’s worth double-checking that you are using the correct procedure to activate remote start with your key fob. Toyota’s system typically involves pressing the lock button and then pressing the remote start button (often the button with a circular arrow) and holding it down for a few seconds. Refer to your owner’s manual to confirm the exact sequence for your specific model.
Troubleshooting Steps and Solutions
Now that we’ve covered the potential causes, let’s look at troubleshooting steps you can take to diagnose and potentially fix the issue yourself:
-
Check Your Remote Connect Subscription Status: If you suspect an expired subscription, you can check your Toyota Owners account online or through the Toyota app to verify your Remote Connect subscription status. If it has expired and you wish to continue using remote start via the key fob and app, you will need to renew your subscription.
-
Replace the Key Fob Battery: This is a simple and inexpensive first step. Refer to your owner’s manual for instructions on how to replace the battery in your key fob. Usually, it involves opening the fob and replacing a small coin cell battery (like a CR2032).

Inspect Vehicle Battery: Check your Toyota’s battery terminals for corrosion and ensure they are clean and tight. If your battery is old or you suspect it might be weak, consider having it tested at an auto parts store or dealership. A weak battery might need to be charged or replaced.
-
Ensure All Doors and Hood are Properly Closed: Walk around your Toyota and firmly close all doors, the hood, and the trunk. Make sure there are no obstructions preventing them from latching completely.
-
Check for Warning Lights: Look at your dashboard for any illuminated warning lights, especially the check engine light. If any are present, address those issues first, as they may be disabling the remote start system. You may need to use an OBD-II scanner to read any error codes and understand the underlying problem.
-
Try the Correct Remote Start Procedure: Consult your Toyota owner’s manual to confirm the precise steps for activating remote start with your key fob. Practice the sequence to ensure you are doing it correctly. Sometimes, a simple misunderstanding of the procedure is the issue.
-
Consider Aftermarket Remote Start Options: If you find that your Toyota’s remote start functionality is indeed tied to a subscription service that you don’t want to pay for, or if you have a base model that didn’t come with remote start, an aftermarket remote start kit can be an excellent solution. Plug-and-play kits are available that integrate seamlessly with your Toyota’s existing electrical system without requiring complex wiring. These kits often offer key fob-based remote start without the need for ongoing subscriptions.

As mentioned in the original post, kits like the Toyota Camry HYBRID Remote Start Plug & Play Kit for 2018-2019 Push Start can provide a reliable, subscription-free remote start experience. These kits are designed for easy installation and can be a cost-effective alternative to dealership solutions or subscription renewals.
When to Seek Professional Help
If you’ve tried these troubleshooting steps and your Toyota key fob remote start is still not working, it’s time to consult a qualified mechanic or your local Toyota dealership. They have the expertise and diagnostic tools to identify more complex issues, such as problems with the vehicle’s computer system, remote start module, or wiring.
Don’t let a non-functional remote start system disrupt your convenience. By systematically troubleshooting the potential causes, you can often resolve the issue yourself or be better informed when seeking professional assistance.
