The Lincoln MKZ is a luxurious car that’s equipped with cutting-edge technology, which includes the convenience of remote start. This feature allows you to start your vehicle from a distance, letting it warm up or cool down before you step inside. However, many Lincoln MKZ owners find themselves frustrated when they attempt to use this feature and it simply doesn’t work. If you are among the many drivers who have faced this issue, read on to discover the common problems, potential solutions, and preventative measures you can take to ensure your remote start operates smoothly.
Understanding the Remote Start System in Your Lincoln MKZ
Before diving into troubleshooting, it’s essential to understand how the remote start system works in your Lincoln MKZ. The remote start function involves a sophisticated network of electronics and software designed to communicate with the car’s engine control module (ECM). When you press the remote start button on your key fob, several things happen:
- Signal Transmission: The key fob sends a radio signal to the vehicle.
- Authentication: The vehicle receives the signal and verifies that it’s an authorized key fob.
- Engine Activation: If authentication is successful, the ECM activates the engine, allowing it to start remotely.
This technical process illustrates why issues may arise—any disruption in the signal, authentication, or engine activation could prevent the remote start from functioning correctly.
Common Reasons for Remote Start Failure
Understanding why your remote start feature may not be functioning is the first step to addressing the problem. Here are some common reasons for Lincoln MKZ remote start failure:
1. Weak Key Fob Battery
One of the most frequent culprits behind remote start issues is a weak or depleted key fob battery. If the battery is low, the key fob may not be able to send a strong enough signal to the vehicle.
2. Unlock/Lock Status
The remote start feature requires the car to be locked. If you accidentally leave the door unlocked after exiting the vehicle or attempt to start the engine without first locking the doors, the remote start will not activate.
3. Vehicle Security Features
Many modern vehicles, including the Lincoln MKZ, are equipped with advanced security features. If the vehicle’s system detects any potential security threats (like doors being ajar), it may disable the remote start function to prevent unauthorized access.
4. Incorrect Engine Status
For the remote start to work, the engine must be in the “off” position. If the engine is already running or has been turned off in an incorrect manner, the remote start system may not engage.
Troubleshooting Your Lincoln MKZ Remote Start
If you discover that your remote start isn’t working, there are several troubleshooting steps you can take before resorting to professional assistance.
Step 1: Check the Key Fob Battery
The first and easiest step is to check the key fob battery. Open the key fob and replace the battery with a new one. Remember to use the correct type that is specified in your owner’s manual. After replacing the battery, try the remote start function again.
Step 2: Confirm the Lock Status
Before trying to use the remote start again, make sure all doors are locked. Press the lock button on your key fob and listen for the locks to engage. Check to ensure that no doors, including the trunk and hood, are ajar.
Step 3: Review Vehicle Security Settings
Take a moment to review the vehicle’s security settings. Some Lincoln MKZ models allow you to adjust security features through the settings menu in the infotainment system. If you find that security settings are overly restrictive, consider modifying them.
Step 4: Reset the Remote Start System
Sometimes, resetting the remote start system can resolve issues. Begin by turning on the ignition without starting the engine. Then, disconnect the battery for about five minutes. Reconnect the battery and turn the ignition off. This action may reset and restore the remote start function.
Step 5: Seek Professional Help
If you’ve gone through the previous steps and the remote start still doesn’t work, it may be time to consult a professional. A Lincoln dealership or a qualified mechanic can perform diagnostic tests to determine if there’s an underlying issue with the vehicle’s electrical system or remote start components.
Preventative Measures for Future Use
Once you’ve resolved the current issue with your Lincoln MKZ’s remote start, it’s essential to take steps to prevent future complications. Here are some recommendations to keep your remote start functioning properly.
1. Regular Maintenance
Schedule regular maintenance checks with your dealership or a trusted mechanic. Regular inspections can help spot potential issues affecting the remote start system, such as wiring problems or battery issues.
2. Protect Your Key Fob
Your key fob is a crucial component of the remote start system. Ensure it is always kept in a safe location and away from moisture, extreme temperatures, and physical damage. If you find your key fob frequently becoming damaged, you may consider purchasing a protective case.
3. Update Your Vehicle Software
Some remote start issues can be resolved by updating the vehicle’s software. Check with your dealership regarding any available software updates which may enhance the performance of your remote start function and other systems.
Conclusion
The Lincoln MKZ offers numerous features that enhance the luxury driving experience, and remote start is undoubtedly one of the most convenient.

By understanding how the system works, knowing common reasons for its failure, and following the right troubleshooting steps, you can resolve most issues without too much hassle.
In situations where the problem persists, seeking professional help is the best course of action. With proper care and regular maintenance, you can ensure that your Lincoln MKZ’s remote start feature will work seamlessly, helping you stay in control of your driving comfort, no matter the season. Remember, the key to a well-functioning vehicle lies in understanding its systems and taking proactive measures to maintain them.
What are the most common reasons for a Lincoln MKZ remote start not working?
The most common reason a Lincoln MKZ’s remote start might fail is due to the vehicle not meeting specific safety conditions. For instance, the doors must be closed, and the vehicle must be in park. If any of these conditions are not satisfied, the remote start feature will disable itself to ensure safety and prevent accidental starts.
Another prevalent issue stems from battery problems. If the vehicle’s battery is weak or the remote’s battery is dead, it may not engage properly with the remote start function. It’s vital to ensure that both the vehicle’s battery and the remote control batteries are functional when troubleshooting the remote start feature.
How can I troubleshoot the remote start feature?
To troubleshoot the remote start issue, begin by checking your vehicle’s settings. Ensure that the remote start feature is enabled in your vehicle’s settings menu through the dashboard display or the Lincoln App. If it is not activated, enabling it might resolve the problem quickly.
Next, test the remote itself by pressing other buttons, such as the lock or unlock features, to confirm it’s functioning correctly. If those buttons work but remote start does not, consider replacing the remote’s battery. If the remote still doesn’t work after changing the battery, you may need to consult your dealership for further assistance.
Could a faulty key fob be the issue?
Yes, a faulty key fob can certainly impact the functionality of the remote start feature. Over time, key fobs experience wear and tear, which can lead to connectivity issues with the vehicle. If the key fob does not send the start signal effectively, it can prevent the engine from starting remotely.
If you suspect the key fob may be the issue, try using a spare key fob, if available. If the spare fob works for remote starting, you will likely need to replace the original one. However, if neither key fob initiates the remote start, the problem may lie elsewhere in the vehicle’s remote start system, warranting further investigation.
Are there any environmental factors that affect remote start functionality?
Yes, environmental factors can influence the performance of your Lincoln MKZ’s remote start feature. Extremely cold weather can affect battery performance—both for the vehicle and the remote key fob. In such conditions, the electrical systems can underperform or fail temporarily, affecting the remote start’s functionality.
Additionally, physical obstructions can inhibit the signal between your remote and the vehicle. Tall buildings, metal structures, or even dense woods can interfere with the wireless signal. If you find yourself in such an environment, try moving closer to your vehicle or choosing a more open space to test the remote start feature.
Is there a way to reset the remote start system?
Yes, you can reset the remote start system in your Lincoln MKZ by disconnecting the vehicle’s battery. First, ensure the vehicle is turned off and remove the key from the ignition. After disconnecting the battery for about five minutes, reconnect it. This process can reset the onboard computer, potentially clearing minor glitches affecting the remote start feature.
Once the battery is reconnected, try using the remote start again. If the remote start still fails to work, you may need to resort to dealership assistance for a more thorough diagnostic process. They can provide a specialized scan of the vehicle’s systems to identify any underlying issues affecting the remote start functionality.
Can I use a smartphone application for remote start, and will it help?
Yes, many newer Lincoln MKZ models come equipped with the capability to use a smartphone application for remote start. If your vehicle supports it, downloading the Lincoln Connect app allows you to remotely start your car using your phone. This feature can offer convenience and could serve as an alternate way to start your vehicle if the key fob isn’t functioning properly.
Using the app can also help isolate the problem. If the remote start works through your smartphone but not via the key fob, it indicates that the issue lies with the fob itself. However, if the app also fails to initiate the start, it may point toward a more significant issue that requires professional attention.
When should I consult a professional about my remote start issue?
You should consider consulting a professional when basic troubleshooting methods, such as checking batteries and vehicle conditions, do not yield results. If your remote start continues to malfunction despite all safety requirements being met and the key fob functioning properly, it may indicate a deeper issue with the vehicle’s remote start system or wiring.
Additionally, if you’ve attempted to reset the system with no success, or if you receive warning lights on your dashboard related to engine issues, it’s advisable to visit your Lincoln dealership or a certified mechanic. They can provide diagnostics using specialized tools to address any electronic or mechanical issues that may be affecting your remote start feature.
