Why Your Car's Ignition Lock Isn't Working
An ignition lock is a security device that stops your car from starting unless you have the original key. It gets triggered when you use the wheel to provide support while getting in or out of your vehicle or touch it while parked.
It can also be triggered by vandalism or theft. If you're having trouble turning your key, these simple solutions could aid:
The ignition switch for the ignition
The ignition switch is a small part of your car that is essential for driving it. It's among the first things you do on your vehicle, and it activates almost all other systems within the car, too. If it's not working it can lead to many issues.
Wear and tear is the primary reason for an ignition switch breaking. This is a possibility with time, particularly when your keychain is weighted down by other items. You can avoid this by using a separate key for your home and car and by reducing the weight on your keys. The other cause is mechanical problems. It can be difficult to remove or insert the key if the cylinder for ignition is not aligned correctly. If this is the case, you'll need to have it replaced.
The ignition switch may be malfunctioning due to an electrical problem. You might notice the smell of smoke or burning when you attempt to start your car. It is essential to replace it immediately to avoid any further damage.
The ignition switch could be stuck in the ON position. This is a safety feature that stops someone from taking your car keys and re-starting it. Usually, this means there is too much pressure on the ignition switch or the key isn't functioning correctly.
In this case, you can lubricate the lock to see if it helps. This will eliminate any dirt particles hindering the key from turning. Then, you can try again. You can also use a silicone-based lubricant that can help keep dirt from accumulating inside the lock. If you're struggling, try wiggling your key before inserting it once again.
The lock is a cylinder
A car's ignition lock cylinder is the part that mechanically controls that allows the key to be inserted to start the vehicle. The cylinder has pins that move upwards and downwards to allow the key to enter and turn. The pins are held in place by wafer tumblers. Over time the tumblers become worn out or even break, preventing the key from turning. The cylinder could eventually fail which could result in the battery of your car dying and other problems.
The most well-known type is the cylindrical lock. The outer shell is made of cylindrical hole that houses the plug. The shell that covers the outside of a cylinder lock is typically constructed of steel. The plug is typically brass or bronze. Cylinder locks come with a variety of different pins, which allow them to lock or unlock in multiple ways. Certain models come with additional security measures such as snap lines or additional pins to guard against lock bumping and other kinds of lock picking.
It is possible to refine a tough lock using graphite, however these methods don't last for long. It is recommended to replace the ignition lock cylinder. This can be done by removing the old lock from your vehicle, and replacing it with a new one. Keys will need to be replaced to replace the cylinder.
The cost of replacing an ignition lock cylinder typically less than $300 for the standard systems. Certain vehicles have electronic locks that are more expensive to change. It is crucial that the procedure for replacing an ignition cylinder be performed by a certified professional. ignition and key replacement is because the procedure involves removing components that could affect the restraint systems that are supplemental (airbags).
You'll need to unplug the negative battery cables before you can replace the battery. This is important to prevent the possibility of an accident involving airbag deployment. It is also important to disable the airbag system, if your vehicle has one. It is essential to follow the factory instructions. You'll have to reset the anti-theft codes after installing the new ignition lock. This will stop your car from being stolen. It could require a special tool.
The key
If you turn your key, but it fails to start your car, it could be an indication that your ignition lock isn't functioning properly. It's a minor but vital component that ensures only the right key is used to operate your vehicle. It's a mechanical component that works with an electrical component to "read" anti-theft coding to allow your vehicle to start. Over time the key could wear out or damage the wafer tumblers within the lock cylinder. This can make it difficult to turn.
While replacing your key is typically the best option however, you can also attempt some basic troubleshooting methods to fix your car ignition problem at home. Make sure your key is in its correct position and that the indicator is pointing toward the P (Park slot) on the shifter. If not, it could cause the engine to stop starting, and a quick check with your auto dealer may be necessary to find out what's causing the issue.
Another step you can take is to move the the ignition switch, but be cautious not to apply too much pressure or force. This will allow for the release of any small damage to the wafer tumblers that's hindering it from turning. If this fails, you can try making the lock cylinder lubricated with a silicone-based lubricant to get it moving again.
These lubricants can be purchased at your local auto parts store. However, you must apply a high-quality lubricant in order to prevent dirt from accumulating. This can cause further issues down the road. If nothing else works, you must remove the ignition and replace it with a new one. This is a relatively simple procedure that a majority of DIYers can follow with the assistance of online guides or an auto repair manual.
If you've recently been convicted for an DUI or DWI the state you live in might require you to install an ignition interlock device (IID). These devices are designed to stop drunk driving by making drivers breathe into a tube prior to starting their car. The device is installed only by a service provider that is approved, such as Intoxalock and LifeSafer.
The wiring
In a lot of vehicles, the lock cylinder and ignition switch are connected via wires. When you insert your key into the ignition, a current flows through these wires and activates all the electrical systems inside your vehicle. If your electrical system isn't functioning or the switch has a problem staying on it could be because the wire has been cut off. If you cannot find the cause of the problem it is possible to purchase a new ignition switch or cylinder.
Ignition Interlock Devices
A breathalyzer is an ignition interlock device that must be installed in your vehicle in order to meet an enforceable or criminal requirement. Ignition interlocks are made to detect alcohol use disorders by analyzing the breath of a driver before the engine of the vehicle can be started. If the IID detects that the driver's alcohol consumption is greater than the permitted limit, a alarm will sound, and/or the lights will flash to indicate that the vehicle can be stopped and the driver may take a second test.
Ignition Interlocks are a great tool for those with an alcohol use disorder, as they require the user to blow into a mouthpiece before starting the vehicle. They are small and discreet and can be concealed away from the view of others to avoid attracting attention. Interlocks for ignition are leased, not purchased outright and cost ranges from $60-90 a month.
The ignition switch and the ignition cylinder work together to regulate all of the electrical parts in your car. The ignition will not function in the event that one of these components are damaged or worn. If you're experiencing one of these issues, it's essential to have them fixed as soon as possible.
If you are having trouble getting your car started try putting the key in neutral or park, and then turning it. If this doesn't work, you might have to remove the airbag, and then disconnect the battery to gain access to the ignition switch. This is a relatively easy task that can be accomplished using a steering wheel puller or GM key removal tool that you can borrow from AutoZone’s free loan-a-tool service.
