How to Fix Car Ignition Problems
The car won't begin unless the switch transmits an electrical signal to the starter. Normal wear and tear over time can cause the switch malfunction.
You can remove the steering column trim with specialized tools to gain access to the ignition cylinder module. Refer to your repair manual for learn how to do it correctly.
1. Check the Switch
A malfunctioning switch is one of 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 of devices such as the starter. However it's still possible for the switch to get damaged or damaged or corroded.
One sign of a damaged switch is a difficulty turning the key. This can be caused by a variety of things that include improperly inserting the key, or the mechanism wearing out over time. It's also commonplace for people to mix up their keys to their car with those of someone else's, which can cause mechanical damage.
Before calling a locksmith you might want to try a few things. You'll first want to ensure that the battery is fully charged and there aren't any electrical issues in the system. You should also examine the voltage of each component to make sure they're providing enough power. Once you've completed these steps, you'll be able to begin troubleshooting.
Luckily 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 require a flathead screwdriver and something long enough to push the pin into. This could be anything from a paintbrush handle to a Kabob skewer. However, you should avoid using anything brittle that could break inside the hole.
When you're ready to do the work, you'll need to take off any trim pieces that cover the area around the ignition switch. Once you've done this take off and loosen any screws that hold the switch in place and then carefully pull it out. Depending on the model, you might also have to unplug the wires that connect to it. If you have an instruction manual for your vehicle it will explain exactly how to do this.
If the ignition switch isn't functioning, it's best to have it replaced by an expert. It's not easy to replace the ignition switch, without disabling the steering column. This could lead to an unintentional airbag deployment if you do it incorrectly. For this reason, it's best to have your local locksmith handle this for you.
2. Check the Wiring
If you are unable to turn the key in the ignition or your car 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 to be able to spot issues and make the appropriate repairs.
The ignition switch is a low voltage multi-pole electrical switch which is turned by the key. It has four positions: off, accessory, run and "lock." If the switch is in the lock position (which typically has a red indicator), the ignition circuit is in operation and it's not possible to start the engine.
You can use a voltmeter quickly test the ignition switch or coil. The voltmeter should read around 12.6 volts when the ignition switch is in the running position. If the voltage drops below that level, it's a sign there's an open circuit within the system. This could be at the battery, the solenoid or the ignition coil itself.
Remove the electrical connector from the ignition switch to ensure that there are no other components that could interfere with the test. Then set the voltmeter to the resistance or continuity mode and place one lead on one of the terminals on the ignition switch. The other lead should be connected to the positive terminal of the battery. If the voltmeter shows "open" or fails to show any voltage, it is recommended to replace the switch.
Use a brand new ignition key and a high-quality ignition cylinder when replacing the switch to ensure your vehicle runs and starts properly. When replacing locksmith ignition replacement cost , be cautious not to touch the pins of the ignition cylinder with your tools or they'll get stuck and your engine won't be able to start. You'll need to take off the steering wheel and gear selector on some vehicles to gain access to the ignition cylinder. This can be a challenge and isn't recommended until you have an owner's manual that states it's safe. If you don't then you could cause serious damage to your steering column and shift mechanism.
3. Check the Cylinder
If you've gone through the wiring, battery and ignition switch, but you can't get your car start, it could be time to check 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 a key.
You might be noticing that your key does not turn if the cylinder is worn out. Sometimes, the pins within the cylinder get stuck as they adapt to the shape of your key, which could cause your car not to start. The cylinder could also be shaky however 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 inserted.
If you need to jiggle and move your key before it will begin, this is another sign that your cylinder has become damaged. This is a negative sign, and it should be corrected right away, since it will only get worse over time.
To test the cylinder, you'll need to take off the cover on the steering wheel and disconnect the battery. The old ignition switch should be simple to take off, as will the metal ignition cylinder. If you don't have a spare 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 ignition switch and cylinder, ensure that you connect the wiring, secure it and reattach all covers and panels that were removed.
4. Check the Spark Plugs
The spark plug is the ignition system's final link. The engine won't start if the spark plug breaks. 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 the flow of electricity across the spark plug gap, which causes your engine's air and fuel mixture.
Be sure to wear protective tools and gloves before you begin working with your spark plugs. Spark plugs are hot and can cause serious injury when you touch them with your skin.
You may notice a light brown or gray residue on the tip of the electrode if the spark plug is damaged. The electrode could also have an opaque coating. These deposits, or corrosion, can prevent high-voltage electrical current from crossing the spark plug gap and sparking your engine.
If you believe that your spark plugs are at fault You can test them by taking the plugs from their tube in the ignition coil. This can be accomplished by disconnecting the coil as well as the plug wire. After that, you'll need to follow the correct procedure for your vehicle in order to take off the components that are covering the plugs. After you have removed the plugs, you can place them on a surface that is grounded and turn the engine. If they're functioning you should be able to see a strong blue spark near the edge of the central electrode.
If you do not detect a spark, you've identified the problem. The next step is to go back through the ignition system chain, testing each component until you can determine what is blocking the spark plugs from performing their job. Every system will get older and eventually break, and this is particularly applicable to ignition systems. Routine maintenance can help to slow down the process and avoid an issue in the worst case.
