How to Fix Car Ignition Problems
The car won't start unless the switch transmits an electrical signal to the starter. Normal wear and tear over time may cause the switch to malfunction.
Utilizing special tools, you can remove the trim on your steering column and access the ignition cylinder module. Consult the repair manual to get guidance on how to do this properly.
1. Make sure you check the Switch
One of the most frequently encountered ignition issues is a malfunctioning switch. It acts as bridge between two contacts, regulating when relays activate and deactivate. It is less likely to fail due to the fact that it doesn't channel full power of devices like the starter. The switch could still be damaged or corroded.
A defective switch can be identified by a difficulty turning the key. This can be caused by many things, including improperly inserting the key, or deteriorating the mechanism over time. It is also common for people to misplace their keys to their car with those of someone else's, which can result in mechanical damage.
If the switch isn't working, there are a few things you can try before calling a locksmith. First, you must ensure that the battery is fully charged and there are no electrical issues within the system. Also, you should verify the voltage of every component to ensure they are sufficient power. After you've completed the above steps, you can begin troubleshooting.
Fortunately, the ignition switch is pretty easy to replace. It is connected to the ignition module, a round component that holds everything together. To replace it, you'll need a flathead screwdriver and something that is long enough to push the pin inside. This could be anything from a paintbrush handle to a Kabob skewer, but you should avoid using anything that is brittle and break within the hole.
Once you're ready to complete the job, you'll need to remove any trim pieces that cover the area around the ignition switch. After this take off and loosen any screws that hold the switch in place, and then gently remove it. Depending on the model, you might need to disconnect any cables connected to it. If you have an instruction manual for your vehicle, this will tell you exactly how to do this.
If the ignition switch isn't functioning it's recommended to replace it by professionals. It can be difficult to replace the ignition switch without removing the steering column. This could lead to an unintentional deployment of airbags when you don't do it correctly. It is best to leave it to your local locksmith to take care of this.
2. Check the Wire
Your car might not start if you are unable to turn the ignition key or it will not start. This could be due to any number components in the ignition system. It is important to know how the ignition system functions to identify issues and make the appropriate repairs.
The ignition switch is an electrical switch with multiple poles that is operated by the key. It has four positions that are off run, accessory, and "lock." If the switch is locked (which is usually shown by a red light) the ignition circuit is in operation and it is inaccessible to start your vehicle.
To determine if the ignition switch is bad or the ignition coil is defective, you will must conduct a quick electrical test using a voltmeter. The voltmeter should read approximately 12.6 volts when the ignition switch is in the running position. If the voltage falls below that then there is an open circuit somewhere within the system. This could be at the solenoid, the battery or the ignition coil itself.
Connect the electrical connector to ensure that it does not interfere with the test. Then you should set the voltmeter in the continuity or resistance mode and put 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 does not detect any voltage, it is recommended to replace the switch.
Make sure you use a new ignition key and a top-quality ignition cylinder when replacing the switch to ensure your vehicle is running and starts correctly. Also, when replacing the ignition switch, be cautious not to touch the ignition cylinder pins with your tools or they'll get stuck and the engine will not start. In certain vehicles, you'll have to remove the steering column and gear selector in order 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. If you don't, it is possible to cause severe damage to your steering column and shift mechanism.
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 check the cylinder. It's the component that holds your key and is mechanically connected to the lock on the steering wheel so a would-be thief can't control the car without keys.
If ignition barrel replacement near me has started to wear out, you may be noticing that your key isn't able to turn. Sometimes, the pins within the cylinder get stuck when they adjust to the shape of your key, which could cause your car not to start. Or, the cylinder might be shaky however a tap using a small tack hammer can aid in releasing it. Be careful not to mix up the springs and make sure your key is correctly placed.
Another indication that your cylinder is going bad is when you have to move the key around and try different positions before it begins. This is a negative sign, and it must be fixed immediately as it will only worsen over time.
To examine the cylinder you'll need to unplug your battery and remove the cover on 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 own a spare switch, you may be able take your original ignition cylinder and switch to locksmiths for reuse as long as they're in good condition. After replacing the ignition switch and cylinder, ensure that you connect the wiring to secure it, then reattach the panels and covers that you removed.
4. Make sure you check the Spark Plugs
The spark plug is the last link in your ignition chain. When it breaks it stops the engine from running. This can take the form of your car not running at all, or may start but run poorly. In any case, the root is likely to be one of a few things that prevent or impair electricity from crossing the spark plug gap which allows your engine's gas and fuel mixture to start.
Before you begin working on your spark plugs, make sure you're working on a safe surface, using gloves and tools that are protected to prevent getting zapped. Spark plugs can be extremely hot and cause serious injuries if touched with bare hands.
You might notice a light gray or brown fleck on the tip of the electrode when the spark plug is defective. It may also have a black coating on the side of the electrode. These deposits or fouling can stop high-voltage electrical current from crossing the gap between the spark plug and starting an engine.
If you suspect your spark plugs might be the cause, you can test them if you remove them from the tube that is inside the ignition coil. This can be done by disconnecting the coil from the plug wire and following the correct procedure for your vehicle to remove any components that are covering the spark plugs. Once you have removed the plugs, you can place them on a metal surface that is grounded and crank the engine. If they're working you will be able to see a strong blue spark crossing the gap in the middle of the central electrode.
If you don't see any spark, you've found the issue. The next step is to work back through the ignition system chain, testing each component until you can determine what is stopping the spark plugs from doing their job. It's important to remember that all systems wear out and break down with time, and this is especially applicable to ignition systems. Routine maintenance can help to reduce the wear and tear and avoid a major headache at the worst time.
