How to Fix Car Ignition Problems

The car won't begin unless the switch sends an electrical signal to the starter. Over time wear and tear can cause the switch to fail.

You can remove the steering column trim with special tools to gain access to the ignition cylinder module. Consult the repair manual to get guidance on how to do this in a safe manner.

1. Make sure you check the Switch

A bad switch is among the most frequent ignition problems. It acts as an intermediary between two contacts, and controls when relays activate and deactivate. It is less likely to fail because it doesn't channel full power from devices such as the starter. It is still susceptible to being damaged or corroded.

One sign of does a new ignition switch require a new key bad switch is a difficulty turning the key. This can be caused by many things that include incorrectly inserting the key or wearing out the mechanism over time. It's not uncommon to see people confuse their keys with someone else's. This can cause mechanical damage.

Before calling a locksmith ignition replacement cost, you might want to try a few things. First, you'll want to ensure that the battery is charged and that there are no other electrical issues within the system. It is also important to examine the voltage of each component to make sure they're providing enough power. After you've completed these steps, you're ready to begin troubleshooting.

The ignition switch is easy to replace. It's connected to the ignition cylinder, a round module that connects everything. To replace it, you'll need a flathead screwdriver, and something long enough to press the pin inside. You can employ anything from a paintbrush to kabob stick, but avoid anything that is hard as it could be broken into the hole.

Remove any trimming pieces that overhang the switch once you're ready to go. After you've removed the trim pieces remove any screws holding the switch in place. Then, carefully pull it out. Depending on the model, you may also have to unplug the wires that connect to it. If you have an instruction manual for your vehicle, this will tell you exactly how to do this.

It's best to get the ignition switch replaced by an expert in the event that it isn't working. It is possible to replace it by disabling the steering column which could trigger an unintentional deployment of airbags if done improperly. For this reason, it's best to have your local locksmith ignition replacement cost handle this for you.

2. Check the Wiring

If you can't turn the ignition key or your fix car ignition isn't starting, your issue could be due to any number of components of your vehicle's ignition system. It is important to know how the ignition system works so that you can pinpoint issues and make the appropriate repairs.

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

To determine whether the ignition switch is defective or if the ignition coil is defective, you will must conduct a quick electrical test using a Voltmeter. The voltmeter should read around 12.6 volts when the ignition switch is in the run position. If the voltage falls below that level, it's a sign there's an open circuit somewhere within the system. This could be a battery, solenoid or the ignition coil.

Disconnect the electrical connector from the ignition switch so that no other components can interfere with your test. Set the voltmeter in the resistance or continuity modes and place one lead onto one of the terminals on the ignition switch. The other lead should be connected to the positive terminal of the battery. If the voltage gauge shows "open" or doesn't show any voltage then it's time to replace the switch.

Make sure you use a new ignition key and a top-quality ignition cylinder when replacing the switch to ensure that your vehicle runs and starts properly. When replacing the ignition switch, you must be careful not to hit the pins of the ignition cylinder with your tools or they'll get stuck and the engine won't be able to start. In certain vehicles, you'll have to remove the steering column and the gear selector to get access to the ignition cylinder. This can be difficult and isn't recommended until you have a vehicle's owner's manual that states it's safe. Otherwise, serious damage to the steering column or shifting mechanism is likely.

3. Check the Cylinder

If you've gone through the wiring, battery, and ignition switch and still cannot get your car to start, it could be time to look at the cylinder. The cylinder is the piece that holds the key. It is mechanically linked to the steering lock so that burglars won't be able to drive the car without it.

If your cylinder is beginning to wear out, you might notice that the key won't turn. The pins of the cylinder can get stuck as they adapt to your key's shape. This can cause your car to not start. The cylinder could also be sloppy. A tap with the tackhammer can aid. Be careful not mixing with the springs and ensure that the key is correctly placed.

If you are required to jiggle and move your key before it can begin, this is another indication that your cylinder is become damaged. This is a sign of trouble and should be addressed immediately, since it will only get worse with time.

To test the cylinder, you'll have to disconnect your battery and remove the cover from your steering wheel until you are able to access the ignition module. The old ignition switch should be simple to take off, as will the cylinder made of steel. If you don't have a spare ignition switch lying around, it's that you could take your original ignition switch and the cylinder to a locksmith and reuse them, as long as they're in good condition. After replacing the ignition switch and cylinder make sure to reconnect the wiring and secure it before reattaching the panels and covers that you took off.

4. Check the Spark Plugs

The spark plug is the last link in your ignition chain. The engine will not run if the spark plug breaks. It could be in the form of your car not running at all, or it may start but run poorly. In either case, it's likely that one of several things are hindering or preventing the flow of electricity across spark plug gaps, which 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 very hot and could cause serious injuries if they are touched with bare hands.

When a spark plug goes bad, you may observe that the edge of the electrode's central portion has a light gray or brown substance on it. The electrode could also have an opaque coating. These deposits or fouling can stop high-voltage electrical current from crossing the gap between your spark plug, igniting an engine.

If you believe that your spark plugs are at fault you can test them by removing them from their tube inside the ignition coil. This can be done by disconnecting the coil as well as the plug wire. Then, you will need to follow the correct procedure for your vehicle to take off the components that are covering the plugs. After removing the plugs, place them on a metal surface that is grounded and start the engine. If they are working you will be able to see a strong blue spark at the edge of the central electrode.

If you don't detect a spark, you've found the issue. The next step is to go backwards through the ignition chain and check each component until the spark plugs are no longer functioning. All systems wear out and eventually fail This is especially relevant to ignition systems. But, regular maintenance can reduce the wear and tear and prevent a major headache at the worst time.
