How to Fix Car Ignition Problems

A car won't start unless the ignition switch transmits an electrical signal to the starter motor. Over time normal wear and tear can cause the switch to fail.

You can remove the steering column trim using special tools to gain access to the ignition cylinder module. Check your repair manual for guidance on how to do this properly.

1. Check the Switch

A defective switch is one of the most frequently encountered ignition issues. It regulates when relays are activated and deactivated, acting as a bridge. It is less likely to fail because it does not channel the full power of devices like the starter. It is still susceptible to being damaged or damaged or corroded.

A bad switch is identified by a difficulty turning the key. This could be due to a variety of things such as improperly inserting the key, or wearing out the mechanism over time. It is also common for people to mistake their keys to their car with those of another's, which could lead to mechanical damage.

Before contacting a locksmith, you can try a few things. First, you'll want to make sure the battery is fully charged and that there are no other electrical issues that could be affecting the system. It is also important to test the voltage of each component to see if they're capable of supplying enough power. Once you've completed these steps, you're ready to begin troubleshooting.

The ignition switch is simple to replace. It is connected to the ignition module, a round piece of metal that connects everything. It's necessary to use a flathead and something that is long enough to insert the pin. It could be anything from an artist's brush to a Kabob skewer, but it is best to avoid any brittle material that could break inside the hole.

When you're ready to do the work, you'll have to take away any trim pieces that cover 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 also have to unplug any wires connected to it. Find out how to do it in the manual of your vehicle.

It is recommended to have the ignition switch replaced by a professional when it's not working. Replacing it can involve disabling the steering column which could trigger an unintentional deployment of airbags if done improperly. It is best to leave it to your local locksmith to take care of this.

2. Verify the Wire

If you can't turn the ignition key or your car won't start, the issue could be related to any number of parts of your car's ignition system. It's important to understand how the ignition system works to identify issues and make the necessary repairs.

The ignition switch is an electrical switch that has multiple poles and is operated by the key. It has four positions including off run, accessory, and "lock." If the switch is locked (which is usually shown by a red light), the ignition circuit is active and it is impossible to start your car ignition key replacement.

You can use a voltmeter to quickly test the ignition lock repair services switch or ignition coil. The voltmeter should read around 12.6 volts when the ignition switch is in the running position. If the voltage falls below that level, it's a sign there's an open circuit within the system. It could be the battery, solenoid or the ignition coil.

Remove the electrical connector so that it doesn't interfere with the test. Then set the voltmeter to the resistance or continuity mode and place 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 it's time to replace the switch.

Use a new ignition key and a top-quality ignition cylinder when replacing the switch to ensure that your vehicle starts and runs correctly. When replacing the switch, be sure not to hit the pins of the ignition cylinder using your tools. In the event of a collision, they'll get stuck and the engine won't be able to run. In some vehicles, you'll need remove the steering column and the gear selector to access the ignition lock jammed cylinder. This isn't easy and shouldn't be done unless you have an owner's manual that indicates that it is safe to do so. If you do not, it is possible to cause severe damage to your steering column and shift mechanism.

3. Check the Cylinder

If you've sifted through the wiring, battery, and ignition switch and still you can't get your car start, it might be time to check the cylinder. The cylinder is the component which holds the key and is mechanically attached to the steering lock to ensure that a would-be burglar can't drive the car without it.

If your cylinder has started to wear out, you may find that the key doesn't turn. The pins of the cylinder could become stuck as they adapt to your key's shape. This could cause your vehicle to not start. The cylinder could also be shaky and a tap using the small hammer from a tack can aid in releasing it. Just be careful not to crush the springs within and make sure that your key is properly installed prior to tapping.

If you need to jiggle and move the key before it will begin, this is another sign that your cylinder has gone bad. This is a red flag and should be addressed immediately, since it will only get worse with time.

To test the cylinder, you will need to remove the cover on the steering wheel and disconnect the battery. You'll then be able to remove the old ignition switch as well as the cylinder for ignition made of metal. If you don't have a spare switch, you might be able take your original ignition cylinder and switch to locksmiths for reuse as long as they're in good condition. After replacing the ignition switch and cylinder ensure that you connect the wiring and secure it before reattaching the panels and covers that you took off.

4. Check Spark Plugs

The spark plug is the final link in your ignition system chain. The engine won't run if the spark plug breaks. It could be that your vehicle won't start at all, or it will run badly. In either of these scenarios, it's likely that one of several things are preventing or impeding electrical current from crossing spark plug gaps, which then ignites the fuel mixture and air in 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 you touch them with bare skin.

When a spark plug goes bad, you may notice that the tip of the electrode's central portion has a slight brown or gray residue on it. It could also have a black layer on the side of the electrode. These deposits, or fouling, can stop high-voltage electrical current from crossing the gap between the spark plug and igniting your engine.

If you suspect your spark plugs could be the cause, you can test them by having them remove them from their tube inside the ignition coil. This can be done by disconnecting the coil from the plug wire and following the correct procedure for your vehicle to remove the components that cover the spark plugs. After removing the plugs place them on a metal surface that is grounded, and begin the engine. If they are working you will see a bright blue spark near the point of the central electrode.

If you don't see a spark you have identified the problem. The next step is to work through the ignition chain, testing each component until you find out what's hindering the spark plugs from doing their job. It's important to remember that all systems wear down and break down over time, and this is especially applicable to ignition systems. That said, routine maintenance can to slow down the process and avoid a big problem at the worst time.
