How to Fix Car Ignition Problems

A car won't start unless the ignition switch is sending an electrical signal to the starter motor. Normal wear and tear over time can result in the switch not functioning properly.

Utilizing 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 instructions on how to do this correctly.

1. Make sure to check the Switch

A defective switch is among the most frequent ignition problems. It acts as bridge between two contacts, regulating the time when relays are activated and deactivated. Because it isn't able to channel the full power of devices such as the starter, it's a less powerful component that is less likely to fail. The switch can still be damaged or damaged or corroded.

A defective switch can be recognized by a slow time turning the key. This can be due to various reasons such as not inserting the correct key correctly or deteriorating the mechanism over time. It's not uncommon for people to mix their keys up with someone else's. This can cause mechanical damage.

Before calling a locksmith, you can try a few things. You'll first want to ensure that the battery is fully charged and that there are no electrical issues in the system. It is also important to examine the voltage of each component to ensure they are providing enough power. After you've completed these steps, you're ready to start troubleshooting.

The ignition switch is simple to replace. It is connected to the ignition module, which is a round piece of equipment that holds everything together. You'll need to use a flathead and a piece of material long enough to press the pin in. This can be anything from an artist's brush 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 take off any trim pieces covering the area around the ignition switch. After you've removed the trim pieces take off any screws that hold the switch in place. Then carefully take it off. Depending on the model, you may need to disconnect the cables that connect to it. If you have a manual for your vehicle and model, it will show you exactly how to do this.

It is best to have the ignition switch replaced by professionals if it doesn't work. It's not easy to replace the ignition switch, without disabling the steering column. This could lead to an unintentional airbag being deployed when you don't do it correctly. For this reason, it is recommended to let your locksmith take care of this for you.

2. Check the Wire

If you can't turn the key in the ignition or your car won't start, the problem could be related to any number of parts of your car's ignition system. Understanding how the ignition system works can help you spot problems and make the appropriate repairs.

The ignition switch is an electric switch that has multiple poles and is controlled by the key. It includes four positions "off", "accessory", "run" and the "lock". If the switch is in the lock position (which typically has the red indicator), the ignition circuit is active and it is not possible to start the engine.

You can use a voltage meter to quickly test the ignition switch or ignition coil. When the ignition switch is set to run and the voltmeter is reading about 12.6, If the voltage falls below that level, it's a sign there's an open circuit within the system. This could be at the battery, the solenoid or at the ignition coil itself.

Disconnect the electrical connector so that it does not interfere with the test. Then you should set the voltmeter in 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 fails to register any voltage, you must replace the switch.

When you're replacing the switch, make sure to use a new ignition cylinder and a top quality key cut to ensure that your car will start and run properly. Also, when replacing the ignition switch, you must be careful not to strike the ignition cylinder pins with your tools or they'll get stuck and the engine won't be able to start. In certain vehicles, you'll need remove the steering column and gear selector to get access to the ignition cylinder. This isn't easy and is not recommended unless you have an owner's guideline that says it's safe to do so. If you do not, it is possible to cause irreparable damage to your steering column and the shift mechanism.

3. Check the Cylinder

If you've tried the battery, the wiring and the ignition switch but still cannot get your car to start it could be time to inspect the cylinder. It's the component that holds your key and is mechanically connected to the lock on the steering wheel to ensure that thieves can't control the car without a key.

You might observe that your key will not turn if the cylinder is worn out. Sometimes, the pins within the cylinder become stuck when they adjust to the shape of your key, which could cause your car to not start. Or, the cylinder might be shaky, but a tap with a small tack hammer can help to free it. Be careful not to jumble the springs within and make sure that the key is correctly installed prior to tapping.

If you have to jiggle and move the key around before it will begin, it is a indication that your cylinder has gone bad. This is a negative sign, and it must be addressed immediately as it will only get worse over time.


To examine the cylinder you'll have to disconnect your battery and take off the cover on your steering wheel until you're able to access the ignition module. You should then be able to remove the old ignition switch and the cylinder made of metal. If you don't have a spare switch, you might be able take your original ignition cylinder as well as switch to locksmiths for reuse so long as they're in good working order. After replacing the switch and cylinder, make sure you connect the wiring harness, secure it in place and reattach any covers, or panels you removed.

4. Make sure you check the Spark Plugs

The spark plug is the last link in your ignition chain. If it fails it stops the engine from running. It could be that your vehicle won't start at all or will run badly. In either case, it is likely that one or more things are preventing or impeding electricity from jumping across spark plug gaps, which ignites the fuel mixture and air within your engine.

Before you begin working on your spark plugs, be sure you're working on a safe surface, using protective gloves and tools to keep from getting hit with. Spark plugs are hot and can cause serious injuries if you touch them with your naked skin.

If a spark plug goes bad, you might observe that the edge of the central electrode has a slight brown or gray substance on it. It could also have a black coating on the side of the electrode. g28carkeys.co.uk or fouling can hinder high-voltage electrical currents from crossing the gap between the spark plug and starting an engine.

If you suspect your spark plugs could be the cause You can test them if you remove the plugs from their tube inside the ignition coil. You can do this by disconnecting the coil from the plug wire and following the proper procedure for your car to remove any components that are covering the spark plugs. After removing the plugs place them on a surface that is grounded. Then start the engine. If they are working you will be able to see a strong blue spark at the point of the central electrode.

If you aren't seeing a spark, you've identified the problem. Next, you'll need to go backwards through your ignition chain and test each part until the spark plugs aren't functioning. All systems will wear out and eventually break and this is especially relevant to ignition systems. Routine maintenance can help to reduce the time it takes to repair and prevent an issue in the worst case.
