How to
Fix Car Ignition Problems
The car will not start unless the switch sends an electrical signal to the starter. Over time wear and tear could cause the switch to fail.
You can remove the steering column trim using specialized tools to access the ignition cylinder module. Consult your repair manual to learn how to do it right.
1. Make sure you check the Switch
A defective switch is among the most common ignition issues. It controls the moment relays are activated, and deactivated, acting as bridge. It is less likely to fail because it
does a new ignition switch require a new key not channel full power from devices like the starter. The switch can still be damaged or damaged or corroded.
A defective switch is recognized by a slow time turning the key. This could be due to many things, including not inserting the key correctly or deteriorating the mechanism over time. It's also common for people to mistake their keys to their car with the keys of someone else, which can cause mechanical damage.
If the switch isn't functioning there are a few things you can try before calling a locksmith. First, you'll need to make sure that the battery is fully charged and that there aren't any other electrical issues that could be affecting the system. It is also important to verify the voltage of every component to make sure they're supplying enough power. Once you've completed these steps, you can begin troubleshooting.
The ignition switch is simple to replace. It is connected to the
ignition lock repair module, a round component that connects everything. To replace it, you'll require a flathead screwdriver, and something that is long enough to push the pin inside. You can use anything from a paintbrush, to a Kabob stick, but be careful of anything that is brittle, as it can cause damage to the hole.
Remove any trim pieces that overhang the switch when you are ready to go. After this, loosen and remove any screws that hold the switch in place, and then carefully pull it out. Depending on the model, you might need to disconnect the cables that connect to it. You can find out how to do it in the manual of your vehicle.
It's best to get the ignition switch replaced by a professional when it's not working. It can be difficult to replace the ignition switch without disabling the steering column. This could result in an accidental deployment of airbags if you do it incorrectly. Therefore, it's often best to have your local locksmith handle 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 of your vehicle's ignition system. It is important to know how the ignition system functions to identify issues and make the necessary repairs.
The
ignition key replacement cost switch is an electric switch that has multiple poles and is operated by a key. It has four positions that are off run, accessory, and "lock." If 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 be reading around 12.6 volts when the ignition switch is in the run position. If the voltage drops below that level, it's a sign there's an open circuit within the system. This could be the solenoid, the battery or the ignition coil.
Disconnect the electrical connector from the ignition switch to ensure that no other components can interfere with your test. Then set the voltmeter to the resistance or continuity mode and place one lead on one of the ignition switch's terminals. The other lead should go 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 brand new ignition key and a high-quality ignition cylinder when you replace the switch to ensure your vehicle starts and runs correctly. When replacing the ignition switch, be cautious not to touch the pins of the ignition cylinder 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 some vehicles to gain access to the ignition cylinder. This can be a challenge and is not recommended unless you have an owner's guideline that says it's safe to do this. Otherwise serious damage to the steering column and shifting mechanism is likely.
3. Check the Cylinder
If you've tried the battery, the wiring, and the ignition switch, but still cannot get your car to start, it may be time to inspect the cylinder. The cylinder is the piece which holds the key and is mechanically attached to the steering lock so that a would-be burglar can't drive the car if it's not there.
You might notice that your key will not turn if the cylinder has worn out. Sometimes, the pins in the cylinder become stuck when they adjust to the shape of your key, which can cause your
car ignition locked to not start. Or, the cylinder might be shaky and a tap using a small tack hammer can aid in releasing it. Be sure not to mix with the springs and ensure that the key is properly placed.
Another indication that your cylinder is going bad is when you have to jiggle the key and test it in various positions before it starts. This is a bad indication and needs to be fixed immediately, since it will continue to get worse as time passes.
To test the cylinder, you'll need to unplug your battery and take off the cover from your steering wheel until you are able to access the ignition module. You'll then be able to pull out the old ignition switch and the metal ignition cylinder. If you don't own an extra switch, you might be able to take your original ignition cylinder as well as switch to locksmiths for reuse so long they're in good shape. After replacing the ignition switch and cylinder ensure that you connect the wiring and secure it before reattaching the covers and panels you took off.
4. Check Spark Plugs
The spark plug is the last link in your ignition system chain. If it fails it will stop the engine from running. It could be that your car will not start at all or it will run poorly. In either of these scenarios, it's likely that one or more things are hindering or preventing the flow of electricity across spark plug gaps, which ignites the air and fuel mixture within your engine.
Be sure to use gloves and protective tools before you begin working with your spark plugs. Spark plugs can be extremely 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 central electrode is covered with a slight brown or gray substance on it. The electrode could also have a dark coating. These deposits or fouling can prevent high-voltage electrical current from jumping across the gap between your spark plug, igniting an engine.
If you believe that your spark plugs may be to blame You can test them by taking the plugs from their tube in the ignition coil. This can be done by disconnecting the coil from the plug wire, and following the appropriate procedure for your car to remove any components that are covering the spark plugs. After removing the plugs, place them on a metal surface that is grounded, and begin the engine. If they're working you should see a strong blue spark crossing the gap at the tip of the central electrode.
If you don't detect a spark, you've identified the problem. The next step is to work through the ignition chain, testing each part until you discover what's stopping the spark plugs from doing their job. All systems will wear out and eventually break and this is especially relevant to ignition systems. However, regular maintenance can help to slow down the process and avoid a big headache at the worst possible moment.
