How to Fix Car Ignition Problems

The car ignition switch repair won't begin unless the switch sends an electrical signal to the starter. Normal wear and tear over time may cause the switch malfunction.

Using special tools, you can remove your steering column trim and gain access to the ignition cylinder module. Consult the repair ignition lock cylinder manual to get guidance on how to do this in a safe manner.

1. Check the Switch

One of the most frequent ignition issues is a malfunctioning switch. It controls the moment relays are activated, and deactivated through the use of a bridge. It is less likely to fail because it does not channel the full power from devices like the starter. However, it's still possible for the switch to get damaged or corroded.

One sign of a bad switch is the difficulty in turning the key. This can be caused by various reasons that include not inserting the correct key correctly or wearing down the mechanism over time. It's not uncommon to see people confuse their keys with keys from someone else's. This can result in mechanical damage.

If the switch isn't functioning, there are some things you can try before calling a locksmith. First, you'll want to make sure that the battery is fully charged and there aren't any other electrical issues that could be affecting the system. Also, you should examine the voltage of each component to ensure they are sufficient power. After you've completed these steps, you'll be able to begin troubleshooting.

Luckily the ignition switch is simple to replace. It is connected to the ignition module, a round piece of metal that connects everything. To replace it, you'll need a flathead screwdriver and something long enough to push the pin inside. You can make use of anything from a paintbrush to Kabob stick, but you should avoid anything that is hard as it could cause damage to the hole.

When you're ready to do the work, you'll need to remove any trim pieces that cover the area around the ignition switch. After taking off the trim pieces, remove any screws that are holding the switch in place. Then, carefully pull it out. Depending on the model, you might need to disconnect any cables that connect to it. You can find out how to do this in the manual of your vehicle.

If the ignition switch isn't functioning it's recommended to replace it by professionals. It is possible to replace it by turning off the steering column, which may trigger unintentional deployment of airbags if done in a wrong manner. This is why it is recommended to let your local locksmith handle this for you.

2. Verify the Wire

If you are unable to turn the key in the ignition or your car isn't starting, your 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 to be able to spot issues and make the appropriate repairs.

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

To determine if the ignition switch is bad or if the ignition coil is faulty, you'll need to do a quick electrical test with the help of a voltage meter. When the ignition switch is running, the voltmeter should show approximately 12.6, If the voltage is below that, there is an open circuit somewhere within the system. It could be the solenoid, battery or the ignition coil.

Connect the electrical connector to ensure that it does not interfere with the test. Set the voltmeter on the continuity or resistance modes and place 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 is "open" or does not register any voltage, you should replace the switch.

Use a new ignition key and high-quality ignition cylinder when replacing the switch to ensure that your vehicle runs and starts properly. When replacing the switch, make sure not to touch the pins of the ignition cylinder using your tools. Otherwise, they'll get stuck and the engine won't run. You'll have to take off the steering wheel as well as the gear selector in certain vehicles to access the ignition cylinder. This isn't easy and shouldn't be done unless you have an owner's manual that states that it is safe to do so. If you do not you could cause irreparable 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 still cannot start your car, it may be time to inspect the cylinder. It's the component that holds your key and is mechanically connected to the lock on the steering wheel so that a potential thief cannot control the car without keys.

If your cylinder has started to wear out, you could be noticing that your key isn't able to turn. The pins of the cylinder can get stuck as they adapt to the shape of your key. This could cause your car to not start. Alternatively, the cylinder may be shaky and a tap using the tack hammer may assist in releasing it. Be careful not mixing with the springs and ensure that the key is properly installed.

If you have to move the key before it will start, this is another indication that your cylinder has gone bad. This is a red flag and should be addressed immediately, as it will continue to get worse as time passes.

To examine the cylinder, you must remove the cover for the steering wheel and disconnect the battery. The old ignition switch should be simple to take off, as will the cylinder made of steel. If you don't have an extra switch, you might be able to take your original ignition cylinder and switch to a locksmith for reuse as long they're in good shape. After replacing the switch and cylinder, ensure that you reconnect the wiring harness and secure it and reattach any covers or panels you've removed.

4. Check Spark Plugs

The spark plug is the last link in your ignition system chain. The engine will not run if the spark plug breaks. It can be that your car won't start at all or will 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 inside your engine.

Be sure to use gloves and protective tools before you begin working with your spark plugs. Spark plugs are hot and could cause serious injury if you touch them with your skin.

If a spark plug goes bad, you might observe that the edge of the electrode's central portion has a slight brown or gray residue on it. It could also have a black coating on the opposite side of the electrode. The deposits or fouling may hinder high-voltage electrical currents from jumping across the gap between your spark plug, igniting an engine.

If you think that your spark plugs could be at fault you can test them by removing them from their tube in the ignition coil. You can do this by disconnecting the coil from the plug wire and following the proper procedure for your car to remove the components that cover the spark plugs. After you have removed the plugs, place them on a metal surface that is grounded and start the engine. If they're good, you should be able to see a strong blue spark crossing the gap between the tip of the central electrode.

If you don't see any spark, you have found the problem. The next step is to go backwards through the chain of ignition and check each component until the spark plugs are no longer functioning. All systems will wear out and eventually fail, and this is particularly relevant to ignition lock repair near me systems. But, regular maintenance can slow the process down and avoid a major headache at the worst moment.
