How To Remove Push Start Button Nissan

The question of how to remove a push start button on a Nissan isn't straightforward. The push start button, also known as an intelligent key system or keyless ignition system, is integrated into the vehicle's security and electronic systems. Therefore, completely removing it and expecting the car to function normally is generally not possible without significant and potentially damaging modifications to the car's computer system. However, there might be scenarios where you want to temporarily disable it or remove the physical button itself. This article will explore those scenarios and provide guidance.

Why This Matters: Understanding the Complexity

Understanding why removing the push start button is difficult is crucial. This isn't just a simple on/off switch. It's tied into several critical systems:

Security System: The push start system is linked to the car's anti-theft system. Removing it could trigger alarms or prevent the car from starting altogether.
Immobilizer: The immobilizer verifies the key fob's presence before allowing the engine to start. Removing the button disrupts this communication.
Electronic Control Unit (ECU): The ECU is the car's brain, and it's programmed to work with the push start system. Tampering with it can lead to serious engine problems.
Body Control Module (BCM): The BCM controls various electronic functions, including the push start system, interior lights, and power windows. Disconnecting the button could impact these features.

Therefore, attempting to completely remove the push start button without understanding these interconnected systems can cause more harm than good. You could end up with a non-functional vehicle and hefty repair bills. It's highly recommended to consult with a qualified automotive technician before attempting any modifications.

Scenarios Where You Might Want to Remove or Disable the Button

While complete removal is generally not recommended, there are a few situations where you might consider temporarily disabling or removing the physical push start button:

Preventing Accidental Starts: If you have young children or pets, you might worry about them accidentally starting the car.
Theft Prevention: While the push start system itself is an anti-theft measure, some individuals explore additional layers of security. However, directly tampering with the button is not typically the solution.
Repair or Replacement: If the button is damaged or malfunctioning, you might need to remove it for repair or replacement.
Aesthetic Reasons: Though uncommon, some owners might want to modify the interior and remove the button for aesthetic purposes. This is strongly discouraged as it will likely disable the starting system entirely.

How to Safely Address These Scenarios

Instead of completely removing the push start button, consider these safer alternatives:

Disabling the Key Fob: Most key fobs have a way to be temporarily disabled. Consult your owner's manual for instructions on how to put the key fob in "sleep" mode. This will prevent the car from starting, even if the button is pressed.
Using a Steering Wheel Lock: A physical steering wheel lock is a visible deterrent to theft and prevents the car from being steered, regardless of whether the push start button works.
Installing an Aftermarket Security System: Consider installing an aftermarket security system with additional features like GPS tracking, remote start disabling, and alarm notifications.
Replacing a Damaged Button: If the button is damaged, it can often be replaced without affecting the rest of the system. Contact a Nissan dealership or a qualified mechanic for replacement parts and installation. The process usually involves removing the surrounding trim pieces carefully and disconnecting the button's wiring harness. Always disconnect the car battery before working on any electrical components.

If you absolutely must remove the physical button for repair or replacement, here's a general outline (but remember, consult a professional):

Disconnect the Battery: This is the most important step to prevent electrical shocks and damage to the car's electrical system.
Locate the Button: The push start button is usually located on the dashboard or center console.
Remove Surrounding Trim: Use a plastic trim removal tool to carefully pry off any surrounding trim pieces. Be careful not to scratch or damage the trim.
Disconnect the Wiring Harness: Once the trim is removed, you should see the wiring harness connected to the button. Gently disconnect the harness by pressing the release tab.
Remove the Button: Depending on the design, the button may be held in place by clips or screws. Remove these to release the button.

Reinstallation is the reverse of removal. Ensure the wiring harness is securely connected and the trim pieces are properly reattached.

Real-World Owner Experiences

Many Nissan owners have faced challenges with their push start systems. Some have reported issues with the button becoming unresponsive, while others have expressed concerns about security. Here's what some owners have learned:

Regular Key Fob Battery Replacement: A weak key fob battery is a common cause of push start problems. Replace the battery regularly to ensure reliable operation.
Consulting the Owner's Manual: The owner's manual contains valuable information about the push start system, including troubleshooting tips and security features.
Seeking Professional Help: When in doubt, consult a qualified mechanic or Nissan dealership. They have the expertise and tools to diagnose and repair push start system issues safely and effectively.
Forums and Online Communities: Online forums dedicated to Nissan vehicles can provide helpful information and advice from other owners who have experienced similar problems. However, always verify the accuracy of the information before attempting any repairs yourself.

One common anecdote is about owners accidentally leaving their cars running because they couldn't hear the engine and didn't realize the car was still on. This underscores the importance of being aware of the system's operation and relying on visual cues on the dashboard.

FAQs About Removing a Nissan Push Start Button

Q: Can I just cut the wires to the push start button?

A: Absolutely not! Cutting the wires will likely damage the car's electrical system and prevent it from starting. It could also trigger the alarm and immobilizer. This is highly discouraged.

Q: Will removing the button disable the key fob?

A: Removing the button itself shouldn't disable the key fob entirely, but it will prevent you from starting the car using the button. The key fob will still be able to lock and unlock the doors, and potentially remote start the vehicle (if equipped).

Q: Is there a way to bypass the push start button in an emergency?

A: Some Nissan models have a hidden key slot that can be used to start the car if the push start system fails. Consult your owner's manual for the location of the key slot and instructions on how to use it.

Q: Can I install a remote start system with the push start button?

A: Yes, many aftermarket remote start systems are compatible with Nissan vehicles that have push start buttons. However, it's important to choose a system that is specifically designed for your car's model and year. Professional installation is highly recommended to ensure proper integration and avoid any damage to the car's electrical system.

Q: I want to install a "kill switch" to disable the push start. Is this a good idea?

A: Installing a kill switch that interrupts a critical circuit can be an effective anti-theft measure. However, it needs to be done correctly by a qualified professional to avoid damaging the car's electronics. Consider consulting with an automotive security specialist.

In conclusion, while the idea of removing a Nissan push start button might seem appealing in certain situations, it's generally not a practical or safe solution. Explore the alternative methods mentioned above or consult with a qualified automotive technician for the best course of action. Remember, safety and proper vehicle operation should always be your top priorities.
