How to
fix ignition switch car ignition (
please click the following article) Problems
The car won't begin unless the switch transmits an electrical signal to the starter. Over time normal wear and tear may cause the switch to malfunction.
Using special tools, you can take off the steering column trim and access the ignition cylinder module. Check your repair manual for guidance on how to do this in a safe manner.
1. Make sure to check the Switch
One of the most common ignition problems is a bad switch. It functions as bridge between two contacts, regulating when relays activate and deactivate. Because it doesn't channel the full power of devices such as the starter, it's a less powerful component that's less likely fail. The switch could still be damaged or damaged or corroded.
One sign of a bad switch is a difficulty turning the key. This can be caused by a number of factors, including incorrectly inserting a key or the mechanism being worn out over time. It's not uncommon to see people mix their keys up with those of others. This can result in mechanical damage.
Before calling a locksmith, you can try a few things. First, make sure that the battery is fully charged and that there aren't any other electrical issues within the system. Also, you should check the voltage of every component to ensure that they are supplying enough power. After you've completed the above steps, you're ready to begin troubleshooting.
Fortunately the ignition switch is simple to replace. It's connected to the ignition cylinder, a round module that holds everything together. To replace it, you'll require a flathead screwdriver and something long enough to push the pin inside. You can make use of anything from a paintbrush to a Kabob stick, but you should avoid anything that is hard as it could break into the hole.
When you're ready to do the work, you'll need to remove any trim pieces covering the area around the ignition switch. After that take off and loosen any screws that keep the switch in place, and then gently remove it. Depending on the model, you might also need to disconnect the wires that connect to it. If you have a manual for the vehicle you own and model, it will show you exactly how to do it.
If the ignition switch isn't working it is recommended to replace it by professionals. Replacing it can involve turning off the steering column, which could trigger an unintentional airbag deployment if it's done incorrectly. It's best to allow your locksmith to handle this.
2. Check the Wiring
If you are unable to turn the ignition key or your car won't start, your issue could be related to any number of components in your car's ignition system. Understanding how the ignition system functions will help you determine the cause of the problem and make the appropriate repairs.
The ignition switch is an electrical switch that has multiple poles and is operated by the key. It has four positions that are off run, accessory, and "lock." When the switch is in the lock position (which usually has the red indicator), the
ignition and key replacement circuit is active and it's not possible to start the engine.
You can use a voltmeter to quickly test the ignition switch or coil. If the ignition switch is set to run, the voltmeter should show about 12.6, If the voltage falls below that, it means there's an open circuit within the system. This could be at the battery, the solenoid or at the ignition coil itself.
Remove the electrical connector from the ignition switch to ensure there are no other components that could interfere with your test. Set the voltmeter on the resistance or continuity modes and then 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 voltmeter is "open" or fails to show any voltage, it is recommended to replace the switch.
Make sure you use a new ignition key and a top-quality ignition cylinder when you replace the switch to ensure that your vehicle is running and starts correctly. When replacing the ignition switch, you must be careful not to hit the ignition cylinder pins with your tools, or they'll get stuck and your engine won't be able to start. In certain vehicles, you'll need to remove the steering column and gear selector to access the ignition cylinder. This can be a challenge and isn't recommended until you have an owner’s manual that says it's safe. Otherwise, serious damage to the steering column and shifting mechanism is possible.
3. Check the Cylinder
If you've tried the battery, the wiring and the ignition switch but still cannot start your car it could be time to check the cylinder. The cylinder is the component that holds the key. It is mechanically attached to the steering lock to ensure that burglars won't be able to drive the car without it.
You may be noticing that your key does not rotate if the cylinder is worn out. Sometimes, the pins in the cylinder become stuck when they adjust to the shape of your key, which could cause your
car key ignition replacement near me not to start. Or, the cylinder might be shaky and a tap using the tack hammer may aid in releasing it. Just be careful not to disturb the springs in the cylinder and ensure that your key is properly inserted before tapping.
If you have to jiggle and move the key before it will start, this is another sign that your cylinder has gone bad. This is a bad indication and should be addressed immediately, since it will only get worse with time.
To examine the cylinder you'll have to disconnect your battery, and then remove the cover around your steering wheel until you're able to access the ignition module. The old ignition switch should be simple to remove, as should the cylinder for ignition made of metal. If you don't have an extra switch, you may be able to bring your original ignition cylinder as well as switch to locksmiths for reuse as long as they're in good working order. 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 last link in your ignition chain. If it fails it will stop the engine from running. This could take the form of your car not running at all, or may start but not run well. In any case, the root is likely to be one of the factors that block or hinder electricity from jumping across the spark plug gap which ignites your engine's air and fuel mixture to run.
Be sure to use gloves and protective tools before you begin working with your spark plugs. Spark plugs can be very hot and cause serious injuries if touched by hands without gloves.
When a spark plug is bad, you might notice that the tip of the central electrode is covered with a light gray or brown substance on it. The electrode could also be covered with a dark coating. These deposits, or corrosion, can prevent high-voltage electrical current from crossing the gap between the spark plug and igniting your engine.
If you suspect your spark plugs might be the culprit you can test them by having them remove the plugs from their tube inside the ignition coil. This can be done 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 removing the plugs, place them on a metal surface that is grounded. Then start the engine. If they're good you should see a strong blue spark extending across the gap at the tip of the central electrode.
If you aren't seeing a spark, you have found the problem. The next step is to work back through the ignition chain, testing each part until you can determine what is blocking the spark plugs from doing their job. It is important to keep in mind that all systems wear out and break over time, and this is especially applicable to ignition systems. But, regular maintenance can reduce the wear and tear and avoid a big headache at the worst possible time.
