Car Ignition Lock: A Simple Definition
Why Your Car's Ignition Lock Isn't Working
An ignition lock is a security feature that prevents your car from starting unless you have the original key. It is activated when you use the wheel for support while getting out or in your vehicle or even touch it when you are parked.
It can also be caused through theft or vandalism. You can repair your key if you are having difficulty turning it.
The ignition switch for the ignition
The ignition switch is a tiny 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 the other systems in the car too. So when it doesn't work it could be a major issue.
Wear and tear is the main cause of a car ignition switch failing. This is a possibility with time, particularly when your keychain is being weighed down by extra items. You can prevent this from happening by having a separate key for your home and car and by reducing the weight on your keys. Mechanical issues are another reason. If the ignition cylinder is disaligned, it could make it difficult to remove or insert your key. If this is the case, you'll need to have it replaced.
Your ignition switch might be malfunctioning due an electrical problem. In this instance, you might notice smoke or a burning odor when you attempt to start your vehicle. If this happens it is important to get it repaired in the earliest time possible to prevent further damage.
Another reason you might be unable to start your car is because the ignition switch is stuck in the ON position. This is an alarm system that blocks anyone from taking out your key and then starting the engine. This typically means that you are applying too much pressure on the ignition switch, or your key doesn't work properly.
Try lubricating the lock in the second case to see if this helps. This will get rid of any dirt particles preventing the key to turn. You can then try again. You can also use a silicone-based lubricant to prevent dirt from accumulating inside the lock. If you're still having trouble, try wiggling your key before inserting it once again.
The lock the cylinder
The ignition lock cylinder in a car is the part that mechanically controls in which the key is in to start the car. The cylinder is equipped with pins that move upwards and downwards to allow the key to enter and out. The pins are fixed by wafer tumblers. Over time the tumblers become worn out or break, preventing the key from turning. The cylinder could eventually fail, resulting in a dead car battery and other issues.
Cylinder locks are the most common type of car lock. They consist of an outer shell with a cylindrical hole in which the plug is housed. The shell that covers the outside of a cylinder lock is generally constructed of steel. The plug is often brass or bronze. Cylinder locks can be found with a variety of different pins that allow them to lock or unlock in a variety of ways. Certain cylinder locks include additional security measures, like snap-line pins or additional pins to prevent lock bumping.
It is possible to tweak a difficult lock using graphite, but these methods aren't always effective for very long. A more reliable solution is to buy a brand new ignition lock cylinder. It is as simple as taking the old cylinder for your ignition lock from your car and replacing it with a new one. New keys are required for a new cylinder.
Standard systems usually cost less than $300 to replace the ignition lock cylinder. Certain vehicles come with electronic locks, which are more expensive to replace. The procedure to replace the ignition cylinder must be performed by an authorized professional. This is because the process involves removing parts that could interfere with the restraint systems that are supplemental (airbags).
To perform the replacement, you'll need to disconnect the battery cable with negative charge. This is important to prevent the risk of an unintentional deployment of airbags. You'll also want to remove the airbag system in the event that it has one. Follow all instructions provided by the manufacturer. After installing the new ignition lock cylinder you'll need to reset your anti-theft code. This will protect your car from being stolen and may require the use of a special tool.
The most important
If your key turns but isn't able to start your car, it could indicate that your ignition lock isn't functioning. This is a tiny but crucial component that makes sure only the correct key is used to operate your vehicle. It's a mechanical part that is connected to an electrical component to "read" anti-theft coding to allow your vehicle to start. Over time the key could wear out or cause damage to the wafer tumblers inside the lock cylinder. This could make it difficult to turn.
While a new key is usually the best option however, you can also try some basic troubleshooting methods to solve the ignition issue in your car at home. First, check that your key is in the proper position on the shifter and that the indicator on the shifter is pointing towards the P (Park) slot. If it's not, this could cause the engine to stop beginning and a quick check with your dealer might be necessary to figure out what's causing the issue.
You can also turn the ignition key, but be careful not to apply too much force or pressure. This could cause slight destruction to the wafer tumblers which is hindering it from turning. If this doesn't help, you can try lubricating it using the use of a silicone lubricant.
These lubricants can be purchased at your local auto parts store. However, you must make sure to use a premium lubricant to stop dirt from accumulating. This will cause more problems later on. If nothing else works you'll need to take off the ignition cylinder and replace it with a brand new one. This is a simple process that most DIYers can follow with the help of online guides or an auto repair manual.
If you've recently been arrested for the crime of DUI or DWI, your state might require that you install an ignition interlock device (IID). G28 Car Keys are designed to deter drunk driving by requiring the driver to breathe into a tube before they can start their car. The device is installed by a reputable provider, such as Intoxalock or LifeSafer.
The wiring
In many automobiles the ignition switch and lock cylinder are connected via wires. When you insert the key into the ignition, current runs through these wires to trigger all the electrical systems in your vehicle. If your electrical system isn't working or the switch is stuck on, it could be that the wire has been cut off. If you are unable to determine the reason behind the problem you might need to get a new ignition switch or cylinder.
Ignition Interlock Devices
An ignition interlock device (IID) is a vehicle breathalyzer which must be fitted in your vehicle as part of a criminal sanctions or legal requirement. Ignition interlocks can detect alcohol-related disorders by measuring the breath of a driver prior to when the engine of the vehicle is able to start. If the IID determines that the driver's BAC exceeds the allowed limit the horn sounds and/or the lights flash, indicating that the driver can pull over and repeat the test.
Ignition Interlocks are a great tool for those with an alcohol-related disorder, as they require the user to blow into a mouthpiece before beginning the vehicle. They are small and discreet and can be hidden to keep them from being noticed. The cost of the ignition interlocks is $60-90 per month. They are not bought for sale.
The ignition switch and cylinder control all electrical components in your vehicle. If any of these components are damaged or worn out, the ignition will not start. If you're experiencing any of these issues, it is important to get them fixed as quickly as possible.
If you're having difficulty starting your vehicle try putting the key in neutral or park and then turning it. If that doesn't work, you might need to take off the airbag, and then disconnect the battery to access the ignition switch. This is a fairly simple task that can be done using a steering wheel puller or GM key removal tool that you can lease from AutoZone's loan-a-tool program for free.
