Causes Of Silverado Turn Key Nothing Happens

If you are attempting to troubleshoot a turn key issue with your vehicle, you may want to look into the reason why this actually occurs. This way, you can properly troubleshoot your vehicle.

1. Ignition switch problem

The most common reason why you may encounter a turn key problem with your Silverado is due to a faulty ignition switch. It is responsible for sending electrical power to your start motor, which in turn is what starts your engine. So if you have a faulty ignition switch, there is no ample power provided to start your motor. This is why your engine fails to start even when you have already turned your key. 

2. Starter motor issues

The starter motor is what turns your engine over and starts it. If you have a malfunctioning starter motor, then you cannot start your engine. Even after turning the key, it fails to start, which can be quite frustrating to deal with.

3. Battery problems

Another potential cause of this turn key issue is having a dead or weak battery. When your battery is either weak or dead, the starter motor will not be able to turn the engine over. So, you need to get your battery checked or tested by a mechanic using a multimeter.

4. Security system issue

There have been many reports of the security system being the cause of the engine failing to start even after turning the key. When the vehicle has detected an unauthorized key or if your security system is not disarmed properly, then the engine will not be able to start. Moreover, a malfunctioning security system can cause your engine to not start even after turning it.

5. Engine problem

When your engine is not in good condition, a turn key issue may also arise. This is the case with your engine not working well, and it may fail to start even after you have turned the key. There are many reasons why you may have engine issues such as with a malfunctioning fuel system, poor compression or low oil pressure.

6. Worn out key

And if none of the above causes is present with your vehicle, then you will need to inspect the key itself. Perhaps your key is damaged or worn out, and this prevents it from turning your ignition switch correctly. You may also have issues with the key not being properly cut, so it fails to engage your lock cylinder and the engine does not start as a result of this.

Silverado Turn Key Nothing Happens – How To Fix It

When you have an issue with the turn key of your Silverado, the best thing to do is to determine what causes the problem. This way, you can troubleshoot your vehicle appropriately. If the culprit is your battery, then you need to make sure that it has enough charge and that you do not have loose connections. 

Clean the terminals since clogging caused by dirt or debris can also cause it to be non-responsive. When you have a dead battery, you also have to replace it. Check or test your battery with a multimeter to make sure it is delivering ample power.

Next, you need to inspect your starter motor. When it is failing to work as it should, it may need to be cleaned, repaired or replaced.

The same is true with your ignition switch. Check if there are signs of damage or wear and tear. The ignition switch tends to break over time, so it is important to have this inspected and make sure it is free from damage.

You may also need to disarm your security system if it is the one that causes the turn key issue. Make sure that your key is authorized and properly matched to your vehicle. Otherwise, it will not create the right response you seek for your engine.

Speaking of engines, you need to make sure there are no damages to its vital components. Your engine may not start at the turn of the key simply because it is broken or there are parts that need to be replaced or repaired.

There is also the possibility of a blown fuse causing this turn key issue. Make sure that your fuses are in good working condition. If you notice a burnt smell, then it means the fuse has blown and will have to be replaced.

Lastly, you need to check your connections and wiring. Any loose connections with your electrical system can prevent the vehicle from starting even if you have turned the key.
