How to Fix Car Ignition Problems

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

Utilizing specialized tools, you can remove your steering column trim and access the ignition cylinder module. Refer to your repair manual for learn how to do it correctly.

1. Check the Switch

One of the most common ignition issues is a malfunctioning switch. It regulates when relays are activated and deactivated through the use of a bridge. It is less likely to fail because it does not channel full power of devices such as the starter. However, it's still possible for the switch to become damaged or corroded.

A defective switch is identified by a difficult time turning the key. This can be caused by many things that include incorrectly inserting the key or the mechanism wearing out over time. It's not uncommon for people to confuse their keys with those of others. This can cause mechanical damage.

If the switch isn't working, there are a few things you could try before calling a locksmith. First, make sure that the battery is fully charged and that there are no electrical issues within the system. You should also test the voltage of each component to see if they're providing enough power. Once you've done these steps, it's time to begin troubleshooting.

Luckily, the ignition switch is easy to replace. It is connected to the ignition module, a round piece of metal that holds everything together. You'll need to use an elongated flathead as well as something long enough for you to press the pin in. You can employ anything from a paintbrush to Kabob stick, but you should avoid anything that is brittle, as it can break into the hole.

When you're ready to do the work, you'll have to remove any trim pieces that cover the area around the ignition switch. After this, loosen and remove any screws that hold the switch in place then gently pull it out. Depending on the model, you may have to cut off any cables that connect to it. You can find out how to do it in the instruction manual for your vehicle.

It's best to get the ignition switch replaced by an expert in the event that it isn't working. Replacing it can involve disabling the steering column, which could trigger an unintentional deployment of airbags if done improperly. For this reason, it's often best to have your locksmith take care of this for you.

2. Check the Wiring

If you're unable to turn the ignition key or your car won't start, your problem could be related to any number of components in your car's ignition system. It is important to know how the ignition system works to be able to spot issues and make the appropriate repairs.

The ignition switch is a low-voltage multi-pole electrical switch that is turned by the key. It has four positions including off run, accessory, and "lock." When the switch is locked (which is typically indicated by a red light) the ignition circuit is activated and it is not possible to start your car.

You can use a voltage meter to quickly test the ignition switch or coil. The voltmeter should read around 12.6 volts when the ignition switch is in the run position. If the voltage falls below that it indicates that there is an open circuit somewhere within the system. This could be a solenoid, the battery or the ignition coil.

Connect the electrical connector to ensure that it does not interfere with the test. Set the voltmeter in the continuity or resistance modes and connect one lead on one of the terminals of 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.

When replacing the switch, be sure to use a new ignition cylinder and a good quality key cut to ensure that your car ignition locked will start and run properly. When replacing the ignition switch, be careful not to hit the ignition cylinder pins with your tools, or they'll become stuck and your engine won't start. You'll have to take off the steering wheel as well as the gear selector in certain vehicles to access the ignition cylinder. This can be a challenge and shouldn't be done unless you have an owner's manual that indicates it's safe to do this. If you do not then you could cause severe damage to your steering column and the shift mechanism.

3. Check the Cylinder

If you've tried the battery, the wiring and the ignition switch, but you are still unable to get your car started, it may be time to inspect the cylinder. The cylinder is the part that holds the key. It is mechanically linked 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 might be noticing that your key isn't able to turn. The pins inside the cylinder can get stuck as they adapt to your key's shape. This could cause your vehicle to not start. The cylinder might also be sloppy. A tap with the small tackhammer may help. Just be careful not to jumble the springs within and make sure that the key is correctly installed prior to tapping.

Another indication that your cylinder is going bad is when you need to move the key around and test it in various positions before it gets started. This is a sign of trouble, and it must be addressed immediately, since it will only worsen over time.

To check the cylinder, you'll need to disconnect your battery, and then remove the cover around your steering wheel until you're able to access the ignition module. You'll then be able pull out the old ignition switch and the cylinder for ignition made of metal. If you don't have an extra switch, you may be able to take the original ignition lock repair 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 reconnect the wiring and secure it before reattaching all covers and panels that you took off.

4. Check Spark Plugs

The spark plug is your ignition system's last link. If it fails it stops the engine from running. It could be that your vehicle won't start at all or it will run poorly. In either case, the reason is likely to be one of several things that prevent or impair electricity from jumping across the spark plug gap which causes your engine's air and fuel mixture to start.

Before you begin working on your spark plugs, be sure that you are working on a level surface and employing protective gloves and tools to prevent getting zapped. Spark plugs are hot and could cause serious injuries if you touch them with your skin.

There may be a slight brown or gray residue on the top of the electrode when the spark plug is damaged. It may also have a black coating on the opposite side of the electrode. These deposits or fouling can stop high-voltage electrical current from jumping across the gap between the spark plug and starting an engine.

If you believe that your spark plugs may be to blame, you can test them by taking them from their tube inside the ignition cylinder replacement near me coil. This can be done by disconnecting the coil from the plug wire, and following the correct 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 turn the engine. If they're good you should be able to see a strong blue spark across the gap in the middle of the central electrode.

If you do not see a spark you have found the issue. Next, you'll need to go backwards through your ignition chain and test each component until the spark plugs aren't functioning. It's important to remember that all systems wear out and break over time, and this is especially true of ignition systems. Routine maintenance can help to slow down the process and avoid an issue in the worst case.
