If your lawn mower won’t shut off with the key, it may be due to a faulty ignition switch or wiring issue. In this situation, it is essential to check and possibly replace the ignition switch, ensuring proper grounding and wire connections.
A lawn mower that won’t shut off with the key can be frustrating, but it’s generally due to a malfunctioning ignition switch or wiring problem. To resolve this issue, start by checking the ignition switch and its connections for faults or damage.
If necessary, replace the ignition switch to ensure proper functioning. Additionally, ensure that the wiring is correctly grounded and connected to avoid any further issues with shutting off the lawn mower.
Common Issues
Experiencing an issue where your lawn mower won’t shut off with the key? This common problem often stems from a faulty ignition switch. Check the switch for continuity to ground to determine if it is the culprit. Troubleshooting and fixing the switch can resolve the persistent running problem.
Low Oil Level
If your lawn mower won’t shut off with the key, one common issue could be a low oil level. The engine requires proper lubrication to function smoothly, and when the oil level is low, it can lead to overheating and other problems. Low oil level is often caused by leaks or burning of oil over time. Ensure that you regularly check and maintain the oil level according to the manufacturer’s recommendations.
Overheating Engine
Another common issue that can prevent your lawn mower from shutting off with the key is an overheating engine. This usually occurs when the engine doesn’t receive adequate airflow or when there is a lack of lubrication due to low oil level. Overheating can cause the engine to malfunction and continue running even when the key is turned off. It is crucial to ensure proper ventilation and oil levels to prevent overheating.
If you suspect that your lawn mower’s engine is overheating, it is essential to address the issue promptly to prevent further damage. Here are a few troubleshooting steps to consider:
- Check the air filter for debris and clean or replace it if necessary.
- Inspect the cooling fins on the engine for any blockages and remove any dirt or debris.
- Ensure that the engine’s cooling fan is functioning correctly and not obstructed.
- Check the oil level and add more if necessary, following the manufacturer’s recommendations.
- If the issue persists, it may be best to consult a professional for further diagnosis and repair.
By addressing these common issues of low oil level and overheating, you can increase the chances of resolving the problem of your lawn mower not shutting off with the key. Regular maintenance and proper care will help ensure the smooth and efficient operation of your lawn mower.

Troubleshooting Methods
When your lawn mower won’t shut off with the key, it can be frustrating and inconvenient. However, there are several troubleshooting methods that can help you diagnose and fix the issue. By following these steps, you can identify the problem and take the necessary actions to resolve it.
Using Kill Switch
To begin troubleshooting, check the kill switch on your lawn mower. The kill switch is designed to shut off the engine in an emergency. Ensure that the kill switch is in the proper position and functioning correctly. If the kill switch is faulty, it may be preventing the engine from shutting off with the key.
Connecting The Switch Stop
Refer to your user manual to locate the switch stop tab on your lawn mower. Ensure that the switch stop is connected properly to allow the engine to stop when the key is turned off. Checking and adjusting the switch stop can help resolve issues with the engine not shutting off as expected.
Disconnecting Spark Plug Wire
Another troubleshooting method involves disconnecting the spark plug wire. This action can help cut off the ignition source to the engine, allowing it to stop running when the key is turned off. Ensure that the spark plug wire is disconnected securely to effectively shut off the engine.
Applying Full Choke
Applying full choke to the engine can be a temporary solution to shut it off when the key is not working. By restricting the air supply to the engine with the choke, you can effectively stop the engine from running, providing a short-term fix while troubleshooting the issue.
Switching Off The Gas
Another method to troubleshoot a lawn mower that won’t shut off with the key is to switch off the gas supply. By turning off the gas valve, you can prevent the flow of fuel to the engine, causing it to stall and stop running. This is a practical way to shut off the lawn mower while addressing the underlying issue.

Fixing Ignition Switch
If your lawn mower won’t shut off with the key, it could be due to a faulty ignition switch. The ignition switch plays a crucial role in controlling the engine’s operation, and when it malfunctions, it can prevent the engine from turning off. In this section, we will discuss three steps to fix the ignition switch: checking continuity to ground, testing the ignition switch, and replacing the ignition switch.
Checking Continuity To Ground
The first step in fixing the ignition switch is to check the continuity to ground. This will help determine if there is any problem with the electrical connection of the switch. To perform this test, follow these steps:
- Disconnect the spark plug wire to ensure safety.
- Locate the ignition switch and remove it from the mower.
- Using a multimeter set to the continuity mode, touch one probe to the ground wire terminal of the ignition switch and the other probe to a known good ground.
- If the multimeter shows continuity, the switch has a good ground connection. However, if there is no continuity, it indicates a grounding issue that needs to be fixed.
Testing Ignition Switch
Once you have checked the continuity to ground, it’s time to test the ignition switch itself. This will help determine if the switch is functioning properly. Follow these steps to test the ignition switch:
- Connect the ignition switch back to the mower.
- Turn the switch to the “ON” position.
- Using a multimeter set to the continuity mode, touch one probe to the power wire terminal of the ignition switch and the other probe to the ground wire terminal.
- If there is continuity, it means the switch is making proper electrical connections. However, if there is no continuity, it indicates a faulty switch that needs to be replaced.
Replacing Ignition Switch
If the previous steps have indicated a faulty ignition switch, it’s time to replace it. Follow these steps to replace the ignition switch:
- Disconnect the spark plug wire to ensure safety.
- Identify the location of the faulty ignition switch on your specific mower model.
- Remove any screws or bolts that are holding the switch in place.
- Disconnect the wiring harness from the old switch.
- Connect the wiring harness to the new ignition switch.
- Secure the new ignition switch in place using the screws or bolts that were removed earlier.
By following these steps, you can fix the ignition switch of your lawn mower that won’t shut off with the key. Remember to prioritize safety and consult the user manual for your specific mower model for accurate instructions.
