10 Tell-Tale Signals You Need To Look For A New Fix Car Ignition How to Fix Car Ignition Problems

The car will not start until the switch sends an electrical signal to the starter. Normal wear and tear over time can cause the switch to malfunction.

With the help of specialized tools, you are able to remove the steering column trim and gain access to the ignition cylinder module. Consult your repair manual to learn how to do it correctly.

1. Check the Switch


A defective switch is one of the most frequently encountered ignition issues. It regulates when relays are activated and deactivated through the use of bridge. It is less likely to fail due to the fact that it doesn't channel full power of devices like the starter. However, it's still possible for the switch to get damaged or damaged or corroded.

One sign of a bad switch is the difficulty in turning the key. This could be due to a number of factors such as incorrectly inserting a key or wearing down the mechanism over time. It's also common for people to mix up their keys to their car with those of another's, which could cause mechanical damage.

Before calling a locksmith you can try a few things. You'll first want to ensure that the battery is fully charged and that there are no electrical issues with the system. You should also verify the voltage of every component to make sure they're supplying enough power. Once you've done these steps, it's time to begin troubleshooting.

Luckily the ignition switch is easy to replace. It's connected to the ignition cylinder, a round module that holds everything together. You'll need to use a flathead and a piece of material long enough to push the pin into. It could be anything from paintbrush handles to Kabob skewer, but you should stay clear of any brittle material that could break within the hole.

If you're ready for the work, you'll have to remove any trim pieces covering the area around the ignition switch. Once you've done this take off and loosen any screws that keep the switch in place and then carefully pull it out. Depending on the model, you may be required to disconnect any wires connected to it. If you have a manual for your vehicle it will explain exactly how to do it.

If the ignition switch isn't working it's recommended to have it replaced by a professional. It's difficult to replace the ignition switch without removing your steering column. This could lead to an unintentional airbag deployment if you do it incorrectly. For this reason, it's often best to have the locksmith in your area handle this for you.

2. Check the Wire

Your car may not start if you are unable to turn the key or it isn't starting. This could be due a number components in the ignition system. It is important to know how the ignition system functions to be able to spot problems and make the right repairs.

The ignition switch is an electric switch that has multiple poles and is operated by a key. It has four positions including off, accessory, run and "lock." When the switch is in the lock position (which usually has the red indicator), the ignition circuit is live and it is not possible to start the engine.

To determine whether the ignition switch is defective or the ignition coil is bad, you need to do a quick electrical test with a voltage meter. The voltmeter should read around 12.6 volts when the ignition switch is in the running position. If the voltage falls below that it indicates that there is an open circuit within the system. This could be at the battery, the solenoid or the ignition coil itself.

Disconnect the electrical connector so that it does not interfere with the test. Then, set the voltmeter to the resistance or continuity mode and put one lead on one of the terminals on the ignition switch. The other lead should be connected to the positive terminal of the battery. If the voltmeter reads "open" or doesn't show any voltage then it's time to replace the switch.

When changing the switch, make sure to use a new ignition cylinder as well as a high quality key cut to ensure that your car will run and start correctly. When you replace the switch, ensure not to hit the pins of the ignition cylinder using your tools. Otherwise, they will become stuck and the engine will not run. In some vehicles, you'll need remove the steering column and the gear selector to access the ignition cylinder. This can be a challenge, and it is not recommended until you have an owner’s manual that states it's safe. If you do not, it is possible to cause serious damage to your steering column and the shift mechanism.

3. Check the Cylinder

If you've worked your way through the wiring, battery, and ignition switch and still cannot get your car to start, it may be time to look at the cylinder. The cylinder is the part that holds the key and is mechanically linked to the steering lock to ensure that a would-be burglar can't drive the car without it.

You might observe that your key will not rotate if the cylinder is worn out. Sometimes, the pins inside the cylinder are stuck as they adapt to the shape of the key, which can cause your car not to start. Alternatively, the cylinder may be shaky and a tap using a small tack hammer can assist in releasing it. Be sure not to mix up the springs and make sure your key is properly inserted.

If you are required to move the key before it will begin, it is a indication that your cylinder has become damaged. This is a sign of trouble and needs to be fixed immediately, since it will continue to get worse as time passes.

To test the cylinder, you'll need to take off the steering wheel cover and disconnect the battery. The old ignition switch should be easy to take off, as will the metal ignition cylinder. If you don't have an extra switch, you may be able to take your original ignition cylinder and switch to locksmiths for reuse as long they're in good shape. After replacing the switch and cylinder ensure that you reconnect the wiring harness, secure it in place and then reattach any covers or panels you removed.

4. Check the Spark Plugs

The spark plug is the last link in your ignition chain. When it breaks it stops the engine from running. It can be that your car will not start at all, or it will run poorly. In any case, the root is likely to be one of several things that prevent or impair electricity from jumping across the spark plug gap which allows your engine's gas and fuel mixture to start.

Make sure you wear gloves and protective tools before you begin working with your spark plugs. Spark plugs are hot and can cause serious injuries when touched with your naked skin.

You may notice a light brown or gray residue on the edge of the electrode if a spark plug is bad. The electrode could also have an opaque coating. G28CarKeys , or fouling, can stop high-voltage electricity from jumping across the gap between the spark plug and igniting your engine.

If you suspect your spark plugs might be the cause, you could test them by remove them from their tube inside the ignition coil. This can be accomplished by disconnecting the coil as well as the plug wire. Then, you'll have to follow the proper procedure for your vehicle in order to take off the components that are covering the plugs. Once you have removed the plugs you can place them on a metal surface that is grounded and crank the engine. If they are good you should see a strong blue spark across the gap at the tip of the central electrode.

If you don't see any spark, you've found the issue. The next step is to work back through the ignition system chain, testing each element until you discover what's stopping the spark plugs from doing their job. It is important to keep in mind that all systems wear down and break down with time, and this is especially the case with ignition systems. Regular maintenance can reduce the wear and tear and avoid a major headache at the worst possible time.
