The 10 Most Dismal Fix Car Ignition Fails Of All Time Could Have Been Prevented
How to Fix Car Ignition Problems


A car won't start unless the ignition switch sends the electrical signal to the starter motor. Normal wear and tear over time could cause the switch to malfunction.

Using special tools, you are able to remove your steering column trim and gain access to the ignition cylinder module. Refer to your repair manual for learn how to do it correctly.

1. Check the Switch

One of the most common ignition problems is a bad switch. It controls the moment relays are activated, and deactivated through the use of a bridge. Because it doesn't harness the full power of devices such as the starter, it's a lighter-duty component that's less likely to fail. However it's still possible for the switch to become damaged or corroded.

One sign of a damaged switch is the difficulty in turning the key. This could be due to various factors that include improperly inserting the key, or the mechanism wearing out over time. It's not uncommon to see people mix keys with keys from someone else's. This could cause mechanical damage.

Before calling a locksmith you may try a few options. First, you must ensure that the battery is fully charged and there aren't any electrical issues in the system. Also, you should test the voltage of each component to see if they're capable of supplying enough power. After you've completed these steps, you can begin troubleshooting.

The ignition switch is simple to replace. It's connected to the ignition cylinder, a round module that connects everything. You'll need an elongated flathead as well as something that is long enough to push the pin into. You can use anything from a paintbrush to a Kabob stick, but be careful of anything brittle as it could be broken into the hole.

Remove any trimming pieces that overhang the switch when you are ready to work. 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 may have to cut off any cables connected to it. If you have a manual for the vehicle you own it will explain exactly how to do this.

It is recommended to have the ignition switch replaced by a professional if it doesn't work. The replacement process involves disabling the steering column which could trigger an unintentional airbag deployment if done improperly. It's best to leave it to your local locksmith to take care of this.

2. Check the Wire

The car may not start if it is difficult to turn the key or if it isn't starting. This could be due a number components in the ignition system. It's important to understand how the ignition system works so that you can pinpoint problems and make the right repairs.

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

You can use a voltmeter quickly test the ignition switch or ignition coil. If the ignition switch is running at a certain voltage, the voltmeter should read around 12.6, If the voltage drops below that, it means there's an open circuit in the system. This could be at the battery, the solenoid or the ignition coil itself.

Disconnect the electrical connector from the ignition switch to ensure that there are no other components that could interfere with your test. Then, set the voltmeter to the resistance or continuity mode and put one lead on one of the ignition switch's terminals. The other lead should be connected to the positive terminal of the battery. If the voltmeter is "open" or does not detect any voltage, you must replace the switch.

If you're replacing the switch, make sure to use a brand new ignition cylinder and a top quality key cut to ensure that your vehicle will start and run correctly. When you replace the switch, be sure not to touch the pins of the cylinder's ignition with your tools. In the event of a collision, they'll get stuck and the engine won't run. In some vehicles, you'll have to remove the steering column and the gear selector to access the ignition cylinder. This can be a challenge and is not recommended unless you have an owner's manual that indicates it's safe to do so. If you don't you could cause severe damage to your steering column and shift mechanism.

3. Check the Cylinder

If you've tried the battery, the wiring, and the ignition switch but still cannot get your car started It could be time to check the cylinder. The cylinder is the piece which holds the key and is mechanically attached to the steering lock so that burglars won't be able to drive the car without it.

If your cylinder has started to wear out, you may find that the key doesn't turn. Sometimes, the pins within the cylinder get stuck as they adapt to the shape of the key, which may cause your car not to start. The cylinder might also be sloppy. A tap with the small tackhammer may help. Be careful not mixing with the springs and ensure that the key is properly inserted.

Another sign that your cylinder is going bad is if you have to move the key around and test it in various positions before it gets started. This is a sign of trouble, and it should be corrected right away as it will only get worse with time.

To examine the cylinder, you will need to remove the cover for the steering wheel and disconnect the battery. The old ignition switch should be easy to take off, as will the metal ignition cylinder. If you don't have an additional ignition switch around, it's likely possible to take your original ignition switch and cylinder to a locksmith to reuse them as long as they are in good condition. After replacing the ignition switch and cylinder make sure to reconnect the wiring and secure it before reattaching the panels and covers that you took off.

4. Check Spark Plugs

The spark plug is the final link in your ignition chain. The engine will not run if the spark plug breaks. It can be that your vehicle won't start at all or will run badly. In either case, it is likely that one or more factors are hindering or blocking electrical current from crossing spark plug gaps, which then ignites the air and fuel mixture in your engine.

Before you begin working on your spark plugs, make sure that you work on a safe surface, employing protective gloves and tools to keep from being zapped. Spark plugs can be extremely hot and could cause serious injuries if touched by hands without gloves.

There may be a slight gray or brown residue on the top of the electrode when a spark plug is bad. It could also have a black coating on the opposite side of the electrode. These deposits, or fouling, may prevent high-voltage electricity from crossing the gap between the spark plug and igniting your engine.

If you suspect that your spark plugs may be to blame you can test them by removing the plugs from their tube in the ignition coil. You can do this by disconnecting the coil from the plug wire and following the correct procedure for your car to remove components that cover the spark plugs. Once you have removed the plugs you can place them on a grounded metal surface and turn the engine. If G28 Car Keys are good, you should see a bright blue spark across the gap in the middle of the central electrode.

If you do not see a spark, you've discovered the problem. The next step is to go through the ignition chain, testing each part until you discover what's blocking the spark plugs from performing their job. It's important to remember that all systems wear out and break over time, and this is especially applicable to ignition systems. However, regular maintenance can help slow the process down and avoid a major problem at the worst moment.
