How to Fix Car Ignition Problems

The car won't start until the ignition switch transmits an electrical signal to the starter motor. Over time, normal wear and tear can cause the switch to malfunction.

Utilizing special tools, you can remove the steering column trim and gain access to the ignition cylinder module. Refer to your repair manual for guidance on how to do this properly.

1. Make sure you check the Switch

A bad switch is one of the most frequently encountered ignition issues. It regulates when relays are activated and deactivated, acting as bridge. It is less likely to fail because it does not channel full power from devices like the starter. The switch can still be damaged or corrosion-prone.

One indication of a defective switch is difficulty turning the key. This could be due to various factors, including not inserting the key correctly or wearing out the mechanism over time. It's not unusual to see people mix keys with someone else's. This can cause mechanical damage.

Before contacting a locksmith, you may try a few options. First, make sure that the battery is fully charged and that there aren't any other electrical issues that could be affecting the system. Also, you should test the voltage of each component to determine if they're providing enough power. Once you've completed these steps, it's time to start troubleshooting.

Fortunately the ignition switch is easy to replace. It is connected to the ignition module, which is a round piece of metal that holds everything together. It's necessary to use an elongated flathead as well as something long enough to insert the pin. It could be anything from an artist's brush to a Kabob skewer, but you should avoid using any brittle material that could break inside the hole.

Remove any trim pieces that are covering the area around the switch when you are ready to get started. After removing the trim pieces, take off any screws that hold the switch in position. Then, carefully take it off. Depending on the model, you may need to disconnect any cables connected to it. If you have a manual for the vehicle you own, this will tell you exactly how to do it.

It is recommended to have the ignition switch replaced by professionals when it's not working. Replacing it can involve disabling the steering column which may trigger unintentional deployment of airbags if done incorrectly. This is why it's best to have your locksmith take care of this for you.

2. Check the Wire

If you can't turn the ignition key or your car won't start, the problem could be related to any of the components of your vehicle's ignition system. It's important to understand how the ignition system functions so that you can pinpoint issues and make the appropriate repairs.

The ignition switch is a low voltage multi-pole electrical switch that can be turned by the key. It has four positions that are off, accessory, run and "lock." When the switch is in the lock position (which typically has an indicator in red) the ignition circuit is in operation and it's impossible to start the engine.

You can use a voltmeter quickly test the van ignition repair switch or coil. The voltmeter should read approximately 12.6 volts when the ignition switch is in the running position. If the voltage falls below that then there is an open circuit somewhere within the system. It could be the solenoid, battery or the ignition coil.

Connect the electrical connector to the ignition switch to ensure that no other components interfere with your test. Set the voltmeter in the continuity or resistance modes and place one lead onto one of the terminals of the ignition switch. The other leads should go to the positive terminal of the battery. If the voltage meter reads "open" or doesn't show any voltage it's time to replace the switch.

When you're replacing the switch, make certain to use a new ignition cylinder and a good quality key cut to ensure that your car will start and run correctly. Also, when replacing the ignition switch, you must be careful not to hit the ignition cylinder pins with your tools or they'll become stuck and your engine will not start. You'll need to take off the steering wheel and gear selector in some vehicles to gain access to the ignition cylinder lock repair cylinder. This isn't easy and should not be done unless you have an owner's manual that indicates it's safe to do so. Otherwise serious damage to the steering column or shifting mechanism is likely.

3. Check the Cylinder

If you have tried the battery, the wiring, and the ignition switch but still can't start your car it could be time to check the cylinder. It's the part that holds your key and is connected to the steering wheel lock so a would-be thief can't control the car ignition replacement near me without the key.

If your cylinder has started to wear out, you could be noticing that your key isn't able to turn. Sometimes, the pins within the cylinder become stuck when they adjust to the shape of the key, which may cause your car ignition barrel replacement near me not to start. The cylinder could also be loose. Tapping it with the tackhammer can help. Be sure not to mix up the springs and ensure that the key is correctly inserted.

If you need to jiggle and move your key around before it will begin, this is another indication that your cylinder is become damaged. This is a red flag and should be corrected immediately, since it will continue to get worse as time passes.

To test the cylinder, you'll need to disconnect your battery and take off the cover around your steering wheel until you're able to access the ignition module. Then, you'll be able to remove the old ignition switch as well as the metal ignition cylinder. If you don't have an extra ignition switch lying around, it's possible to take your original ignition switch and cylinder to a locksmith to reuse them as long as they're in good condition. After replacing the switch and cylinder, make sure you connect the wiring harness and secure it and then reattach any covers or panels that you have removed.

4. Check the Spark Plugs

The spark plug is the final link in your ignition chain. If it fails, the engine can't run. This can take the form of your car ignition switch replacement not running at all, or may start but then run poorly. In either case, it's likely that one of several things are hindering or preventing electricity from jumping across spark plug gaps, which in turn ignites the air and fuel mixture within your engine.

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

When a spark plug is bad, you might notice that the tip of the central electrode is covered with a light gray or brown substance on it. The electrode could also have a dark layer. These deposits or fouling can prevent high-voltage electrical current from crossing the gap of your spark plug, igniting an engine.

If you suspect that your spark plugs may be the cause you can test them by having them remove them from the tube that is inside the ignition coil. This can be done by disconnecting the coil from the plug wire, and following the appropriate procedure for your vehicle to remove components that cover the spark plugs. Once you have removed the plugs, you can place them on a grounded metal surface and then crank the engine. If they're working you will be able to see a strong blue spark crossing the gap at the tip of the central electrode.

If you aren't seeing a spark, you've found the problem. The next step is to go backwards through the chain of ignition and test each component until the spark plugs stop functioning. It's important to remember that all systems wear out and break down over time and this is particularly applicable to ignition systems. However, regular maintenance can to slow down the process and prevent a major headache at the worst possible time.
