How to Fix Car Ignition Problems

The car won't start until the ignition switch transmits an electrical signal to the starter motor. Normal wear and tear over time can cause the switch to malfunction.

You can remove the steering column trim with specially designed tools to access your ignition cylinder module. Refer to your repair ignition lock cylinder manual for learn how to do it right.

1. Make sure you check the Switch

A bad switch is one of the most frequent ignition problems. It regulates when relays are activated and deactivated through the use of bridge. It is less likely to fail because it does not channel the full power from devices like the starter. However it's still possible for the switch to become damaged or corrosion-prone.

A bad switch is recognized by a slow time turning the key. This can be caused by various reasons that include incorrectly inserting a key or the mechanism being worn out over time. It is also common for people to mix up their keys to their car with those of the keys of someone else, which can cause mechanical damage.

If the switch isn't working there are a few things you can try before calling a auto locksmith ignition replacement. 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 verify the voltage of every component to ensure that they are sufficient power. After you've completed the above steps, you'll be able to begin troubleshooting.

Luckily, the ignition switch is pretty easy to replace. It is connected to the ignition module, a round piece of equipment that connects everything. You'll need to use a flathead and a piece of material that is long enough to push the pin into. You can make use of anything from a paintbrush to Kabob stick, but you should avoid anything that is brittle, as it can be broken into the hole.

Once you're ready to complete the work, you'll need to remove any trim pieces that cover the area around the ignition switch. After you've removed the trim pieces take off any screws that hold the switch in position. Then, gently remove it. Depending on the model you might need to disconnect any cables connected to it. If you have a manual for your vehicle it will explain exactly how to do this.

If the ignition switch isn't working it is recommended to have it replaced by professionals. It can be difficult to replace the ignition switch without removing the steering column. This could result in the unintentional airbag deployment in the event that you don't do it correctly. It is recommended to leave it to your local locksmith to handle this.

2. Check the Wire

Your car might not start if you cannot turn the key or if it isn't starting. This could be due to any number of components within the ignition system. It's important to understand how the ignition system works to be able to spot problems and make the right repairs.

The ignition switch is an electrical switch with multiple poles that is operated by the key. It has four positions including off run, accessory, and "lock." When the switch is locked (which is usually shown by an red light) the ignition circuit is active and it is not possible to start your car.

To determine whether the ignition switch is damaged or if the ignition coil itself is faulty, you'll have to conduct an electrical test using the help of a voltmeter. The voltmeter should be reading around 12.6 volts when the ignition switch is in the run position. If the voltage falls below that it indicates that there is an open circuit within the system. It could be the battery, solenoid, or the ignition coil.

Disconnect the electrical connector so that it does not interfere with the test. Set the voltmeter to the continuity or resistance modes and connect 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 reads "open" or doesn't show any voltage it's time to replace the switch.

Use a new ignition key and high-quality ignition cylinder when you replace the switch to ensure your vehicle starts and runs correctly. When you replace the switch, ensure not to touch the pins of the ignition cylinder using your tools. In the event of a collision, they'll become stuck and the engine will not run. You'll need to take off the steering wheel and the gear selector in some vehicles to gain access to the ignition cylinder. This can be difficult and should not be done 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 worked your way through the battery, wiring and ignition switch, but can't 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 attached to the steering lock to ensure that thieves can't drive the car without it.

If your cylinder has started to wear out, you may be noticing that your key isn't able to turn. Sometimes, the pins in the cylinder get stuck as they adapt to the shape of your key, which can cause your car to not start. Alternatively, the cylinder may be shaky however a tap using the small hammer from a tack can help to free it. Be sure not to mix the springs, and ensure that the key is correctly placed.

Another indication that your cylinder is failing is when you need to turn the key and test it in various positions before it gets started. This is a sign of trouble, and it must be addressed immediately because it will worsen over time.

To examine the cylinder you'll have to disconnect your battery and take off 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 well as the cylinder made of steel. If you don't have an extra ignition switch lying around, it's that you could take your original ignition switch and the cylinder to a auto locksmith ignition replacement and reuse them, as long as they are in good condition. After replacing the ignition switch and cylinder, make sure to reconnect the wiring, secure it and reattach the panels and covers that were removed.

4. Check the Spark Plugs

The spark plug is the last link in your ignition chain. If it fails it will stop the engine from running. This can take the form of your car not starting at all, or it could start but then run poorly. In any case, the root is likely to be one of a few things that hinder or prevent the flow of electricity across the spark plug gap, which causes your engine's air and fuel mixture.

Be sure to use protective tools and gloves before you begin working with your spark plugs. Spark plugs can be very hot and could cause serious injuries if they are touched by hands without gloves.

You might notice a light brown or gray residue on the edge of the electrode if the spark plug is defective. It could also have a black coating on the opposite side of the electrode. These deposits, also known as corrosion, can prevent high-voltage electricity from crossing the gap between the spark plug and igniting your engine.

If you suspect that your spark plugs could be to blame, you can test them by removing the plugs from their tube in the ignition coil. This can be accomplished by disconnection of the coil and the plug wire. Then, you will be required to follow the correct procedure for your car 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 then crank the engine. If they're functioning you should see a bright blue spark on the edge of the central electrode.

If you don't see a spark you have discovered the problem. The next step is to go through the ignition chain, testing each element until you discover what's blocking the spark plugs from doing their job. All systems get older and eventually break, and this is particularly true for ignition systems. Routine maintenance can help to slow down the process and prevent major problems at the worst possible time.
