How to Fix Car Ignition Problems The car won't begin to start until the ignition switch is sending an electrical signal to the starter motor. Normal wear and tear over time could cause the switch to malfunction. You can remove the steering column trim using specialized tools to gain access to the ignition cylinder module. Check the repair manual to get guidance on how to do this properly. 1. Make sure car ignition switch repair check the Switch One of the most common ignition issues is a defective switch. It regulates when relays are activated and deactivated by acting as a bridge. It is less likely to fail due to the fact that it doesn't channel full power of devices such as the starter. The switch can still be damaged or damaged or corroded. A defective switch can be identified by a difficulty turning the key. This could be due to many things such as incorrectly inserting the key or the mechanism wearing out over time. It's not common to see people confuse their keys with keys from someone else's. This could cause mechanical damage. Before calling a locksmith you can try a few things. First, make sure that the battery is fully charged and there aren't any electrical issues in the system. It is also important to test the voltage of each component to see if they're supplying adequate power. Once you've completed these steps, you're ready to begin troubleshooting. 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 press the pin inside. You can make use of anything from a paintbrush to Kabob stick, but you should avoid anything that is hard as it could be broken into the hole. Remove any trim pieces that are covering the area around the switch when you are ready to work. After taking off the trim pieces, remove any screws holding the switch in place. Then, carefully pull it out. Depending on the model, you might need to disconnect any cables connected to it. If you have a manual for your vehicle, this will tell you exactly how to do it. It is recommended to have the ignition switch replaced by a professional if it doesn't work. Replacing it can involve disabling the steering column, which may trigger unintentional airbag deployment if it's done improperly. This is why it's best to have your locksmith take care of this for you. 2. Check the Wire Your car might not start if it is difficult to turn the ignition key or it isn't starting. This could be due to a number components in the ignition system. Understanding how the ignition system works will help you determine the cause of the problem and make the necessary repairs. The ignition switch is an electrical switch that has multiple poles and is operated by the key. It has four positions, which include “off”, “accessory”, “run” and the “lock”. When the switch is in the lock position (which typically has an indicator in red), the ignition circuit is active and it is not possible to start the engine. To determine if the ignition switch is bad or if the ignition coil is bad, you must conduct a quick electrical test using a voltage meter. If the ignition switch is running at a certain voltage, the voltmeter should read around 12.6, If the voltage drops below that level, it's a sign there's an open circuit somewhere in the system. It could be the battery, solenoid or the ignition coil. Connect the electrical connector to ensure that it doesn't interfere with the test. Set the voltmeter in the continuity or resistance modes and connect one lead on one of the terminals of the ignition switch. The other lead should be connected to the positive terminal of the battery. If the voltmeter is “open” or fails to detect any voltage, you should replace the switch. When you're changing the switch, make sure to use a brand new ignition cylinder as well as a high quality key cut to ensure that your car will start and run properly. When you replace the switch, ensure not to hit the pins of the ignition cylinder using your tools. Otherwise, they'll become stuck and the engine won't be able to run. You'll need to remove the steering wheel as well as the gear selector on some vehicles to get access to the ignition cylinder. This isn't easy and is not recommended unless you have an owner's manual that states it's safe to do this. If you don't then you could cause irreparable damage to your steering column and the shift mechanism. 3. Check the Cylinder If you've gone through the battery, wiring and ignition switch but can't get your car to start, it might be time to examine the cylinder. The cylinder is the part which holds the key and is mechanically linked to the steering lock to ensure that thieves can't drive the car if it's not there. You might observe that your key will not rotate if the cylinder is worn out. Sometimes, the pins in the cylinder are stuck as they adapt to the shape of the key, which could cause your car not to start. Alternatively, the cylinder may be loose however a tap using the small hammer from a tack can assist in releasing it. Be careful not mixing with the springs and make sure your key is properly placed. If you need to jiggle and move your key around before it will start, this is another indication that your cylinder has gone bad. This is a negative sign and must be addressed immediately because it will get worse over time. To check the cylinder you will need to remove the cover on the steering wheel and disconnect the battery. You should then be able to remove the old ignition switch and the metal ignition cylinder. If you don't own an extra switch, you may be able to take your original ignition cylinder as well as switch to locksmiths for reuse so long they're in good shape. After replacing the switch and cylinder, ensure that you reconnect the wiring harness, secure it in place and then reattach any covers or panels you removed. 4. Check the Spark Plugs The spark plug is the last link in your ignition system chain. The engine won't run in the event that the spark plug fails. It can be that your car won't start at all or it will run badly. In either case, it's likely that one or more things are preventing or impeding electrical current from crossing spark plug gaps, which in turn ignites the mixture of fuel and air within your engine. Before you begin working on your spark plugs, be sure that you are working on a level surface and employing protective gloves and tools to avoid being zapped. Spark plugs can get very hot and could cause serious injuries if they are touched by hands without gloves. If a spark plug goes bad, you may be able to see that the top of the central electrode has some light brown or gray substance on it. The electrode could also be covered with a dark coating. These deposits, or fouling, may prevent high-voltage electricity from crossing the spark plug gap and igniting your engine. If you suspect that your spark plugs might be the culprit You can test them by having them 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 correct procedure for your vehicle to remove any components that are covering the spark plugs. After removing the plugs, place them on a surface that is grounded, and start the engine. If they are good you should see a bright blue spark across the gap at the tip of the central electrode. If you aren't seeing a spark, you've found the problem. Next, you'll need to go backwards through the chain of ignition and test each component until the spark plugs aren't functioning. All systems will wear out and eventually fail and this is especially true for ignition systems. But, regular maintenance can help slow the process down and prevent a major problem at the worst moment.
