Before identifying the causes of turn key failure in a Silverado, it’s important to understand the mechanics of starting a vehicle. When you turn the key in the ignition, power is sent from the battery to the starter, which rotates the engine to start it.
If any component in this process fails, turn key failure can occur. With that in mind, let’s look at some of the most common causes of turn key failure in a Silverado:
Dead battery
A dead battery can be caused by age, lack of use, or leaving lights on overnight. Without enough power, the starter won’t be able to turn the engine over.
Faulty starter
The starter is crucial in turning the engine over when the key is turned. A faulty starter can cause the engine not to turn over, resulting in key failure.
Bad ignition switch
The ignition switch sends power to the starter; a bad ignition switch can prevent power from reaching the starter and cause starting failure. A Bad ignition can also cause the key to getting stuck.
Wiring issues
Wiring issues can prevent power from reaching the starter and cause key failure to start the engine. This issue can be caused by corrosion, damage, or poor connections.
Other potential causes
Other potential causes of starting failure include problems with the security system, anti-theft system, or key itself.
Sometimes the issue may not be with the battery, starter, ignition switch, wiring, or security system; it could be a problem with the computer or the engine that would require a professional diagnosis and repair.
Note: Starting failure when turning the key can stem from multiple issues, and it’s essential to properly diagnose the problem by eliminating possible causes one by one.
Diagnosing the problem is the first step in fixing turn key failure in a Silverado. The following are the steps to take to diagnose the problem:
Tools needed for diagnosis:
Multimeter or battery tester
Test light
Wrench set
Screwdrivers
Check the battery
Use the multimeter or the battery tester to check the battery’s voltage. If the voltage is below 12.4 volts, the battery is likely dead and needs to be replaced.
Check the starter
Use the test light or the multimeter to check for power at the starter when the key is turned to the start position. The starter or ignition switch may be at fault if there is no power.
Check the wiring
Use the test light or the multimeter to check for power at the starter and other components. Look for loose, corroded, or damaged connections that may be causing the problem.
Check the key
It’s important to ensure the key itself is not the problem. A worn out, damaged, or malfunctioning key may not be able to turn the ignition or communicate with the anti-theft system properly.
A worn out, damaged, or malfunctioning key results in turn key failure. Make sure the key is in good condition, and try using a spare key if available.
Check the security system
If the truck is equipped with a security system or an anti-theft system, ensure it is not activated or check for any error codes.
Importance of proper diagnosis silverado ignation
Proper diagnosis is essential to fix the problem correctly. If the problem is not diagnosed correctly, you may replace the wrong part or worsen the problem.
It is important to eliminate possible causes one by one and to use the correct tools and methods to diagnose the problem. If you need help with how to diagnose the problem, it is best to seek professional help.
Fixing Silverado turn key nothing happens issues
Once the problem has been properly diagnosed, it’s time to fix it. The following are the ways to fix common causes of turn key failure in a Silverado:
Step-01: Replacing Dead battery
The battery is usually located in the engine compartment, near the front of the vehicle. Refer to your owner’s manual for the exact location.
To test and replace a dead battery, use a multimeter or tester to check the voltage of the battery; if the voltage is below 12.4 volts, the battery is likely dead and needs to be replaced.
Locate the negative battery cable; it will be marked with a “-” sign or a black cover; use a wrench to loosen the bolt and disconnect the cable.
Locate the positive battery cable; it will be marked with a “+” sign or a red cover; use a wrench to loosen the bolt and disconnect the cable.
Carefully lift the battery out of the compartment and place it on a flat surface.
Carefully place the new battery into the compartment, ensuring it is securely in place.
Connect the positive cable to the new battery, and tighten the bolt with a wrench.
Connect the negative cable to the new battery, and tighten the bolt with a wrench.
Make sure all connections are tight and secure.
Turn the key in the ignition to test the new battery; if the engine starts, the replacement is successful.
Make sure to replace the battery with one that has the same specifications as the original.
Step-02: Replacing Faulty starter
The starter is typically located in the engine compartment, near the bottom of the engine. To test and replace a faulty starter, use the test light or multimeter to check for power at the starter when the key is turned to the start position.
If there is no power, the starter may be at fault.
Disconnect the negative battery cable to prevent any electrical accidents.
Locate the starter wires that connect to the solenoid, use a socket wrench to remove the bolts, and disconnect the wires.
Remove the bolts that hold the starter in place, carefully remove it, and place it on a flat surface.
Place the new starter in the engine compartment, ensuring it is securely in place.
Reattach the starter wires to the solenoid and secure them with bolts.
Reconnect the negative battery cable.
Turn the key in the ignition, listen to the starter engage, and turn the engine over.
When replacing the starter, it’s best to use a starter with the same specifications as the original one and seek professional assistance if unsure about the process.
Step-03: Replacing the Bad ignition switch
Use the test light or multimeter to check for power at the starter and other components. If there is no power, the ignition switch may be at fault.
Depending on the location of the ignition switch, it may be necessary to remove the steering wheel to access the ignition switch. Refer to your owner’s manual for the specific instructions for your vehicle.
Locate the mounting screws or bolts that hold the ignition switch in place and remove them with a screwdriver or a socket wrench.
Remove the ignition switch from the steering column or dashboard.
Install the new ignition switch in the same location, making sure it is securely in place.
If necessary, Reinstall the steering wheel and make sure it is securely in place.
Reconnect the negative battery cable.
Check that power is being sent to the starter and that the engine starts.
Step-04: Fixicing Wiring issues
You will need a test light or a multimeter to diagnose and repair wiring issues. Use the test light or multimeter to check for power at the starter and other components. Look for loose, corroded, or damaged connections that may be causing the problem.
You will need a wiring diagram and appropriate tools to repair the wiring.
Inspect all the wiring in the engine compartment and under the dashboard, and pay attention to frayed, corroded, or disconnected wires.
Use a circuit tester to check for continuity and power in the wiring. This will help you identify which wires are not functioning properly.
Clean the wiring connections with a wire brush or sandpaper to remove any corrosion. This will help to ensure a good connection.
If any of the wirings is damaged, it needs to be replaced. Make sure to use the same type and gauge of wire as the original.
Reconnect the wiring and make sure all connections are tight and secure.
Turn the key in the ignition and check that power is being sent to the starter and that the engine starts.
Note: For fixing wiring issues, it’s best to seek professional assistance as it can be complex and require special tools. Also, it’s important to use the correct size and type of wire to ensure the safety and longevity of the repair.
Step-05: Fixing Other potential issues
