A functional remote car key is a marvel of convenience, allowing you to lock and unlock your car with a simple button press from a distance. When it's in good working order, it's a game-changer, and you might find it hard to remember how you managed without it. However, if your remote stops working, it can be a major inconvenience. If you're faced with a non-responsive car key, here are some potential causes to consider.
Diagnose the Problem
Diagnosing the issue is the first step to regaining control. There are several factors to consider when determining the root of the problem. It could be a single remote that's malfunctioning or all remotes. Alternatively, a problem with the locks could be causing the remote to be ineffective. By testing a few scenarios, you can start to narrow down the issue.
Check All Remotes
You need to determine if the problem is with one car key remote or if the problem is extensive. Test out the other remote, and if your second car key works, this confirms that the problem isolated to one remote fob. If the second remote does not work, that means the problem is bigger than anticipated.
Check the Locks
If your vehicle has a physical key, test that out, too. Make sure to test it in the lock in each door. Also, test the internal locks. If the physical key or buttons inside the vehicle do not work the problem is not with the remote.
Look at the Remote
There are a few issues with the remote that could cause it to no longer work. By identifying the problem, you can determine the solution.
The Battery Died
Remote car fobs are powered by batteries. Given enough time and use the batteries will die. Replacing the battery will resolve the issue. Most car fobs take button or coin cell batteries. Button or coin cell batteries can be purchased online or at most stores that carry batteries. The battery type may be listed in the owner’s manual. You can also confirm the type of battery by opening the case and inspecting the existing battery. You will need to open the remote, remove the old battery and replace it.
If you replace the battery and the remote works that solve the issue. If you replace the battery and the remote still does not work the battery may not have been the issue and there is another problem.
Remote Malfunction
If there are mechanical or electrical issues with the remote fob, this could prevent it from working. Car key remotes are handled a lot and get banged up in the process. They are tossed in bags or pockets and are jostled around with other items. When they have bumped around, buttons can be damaged or electricity can be knocked loose.
Determine if the connections are bad by taking the remote apart. Inspect the interior and look for any disconnects. If this is the case, it may be possible to repair the remote. You will likely need to bring the remote to a dealer or a locksmith for the repair. If you do not wish to fix the remote, or if it is beyond repair you can purchase a new remote. In that case, the new remote will need to be programmed to work with your vehicle.
The Car Key Remote Needs to Be Reprogrammed
It is possible the remote malfunctioned and just stopped working. A key fob needs to be programmed to work with a particular car. This ensures that your fob only locks and unlocks your vehicle, and no one else’s fob works with your vehicle.
If your remote stops working and the battery is not the culprit, and the connections are solid, the fob may need to be reprogrammed to work with your vehicle. This process involves a series of steps that may be outlined in your owner’s manual, or you can find instructions online. If you're not comfortable doing it yourself, you can bring your vehicle and the remote into a dealer or locksmith for professional reprogramming.
Physical Damage
If your car key has been dropped or exposed to water, it's possible that physical damage has occurred. Check the key for any signs of damage, such as cracks or corrosion. Pay close attention to the key's surface and edges, as these are common areas for damage. If you see any, it's best to have the key replaced to avoid further issues.
A Worn Out Physical Key
Over time, your car key may become worn down and no longer fit properly in the ignition. To address this, consider getting a new key cut. You can do this at a local locksmith or a dealership. They will use your existing key as a template to cut a new key that fits your car's ignition perfectly. While this process may still pose a bit of a hassle, it is a far simpler way to check at least one of these issues off of the list.
Damaged Ignition Switch
If your car key is not turning in the ignition switch, the switch may be damaged. Consider having it inspected and repaired by a professional. This type of damage can occur with time; however, it can also result from an attempt to steal your vehicle. If you suspect theft, have it inspected and reported immediately.
Dirt and Debris
Dirt and debris can build up in the keyhole over time, preventing your key from turning properly. Use compressed air or a small brush to clean the keyhole carefully and thoroughly. Do not attempt to jam anything foreign into the hole to remove dirt or debris as this can damage it and possibly create a whole new and costly issue.
Locked Steering Wheel
If your steering wheel is locked in place, your car key may not be able to turn in the ignition. If you turn the key and jiggle the wheel back and forth, you may be able to fix the problem. If this doesn’t help, take a deep breath and move on.
Ignition Cylinder Problems
In some cases, the issue might not be with the key itself but with the ignition cylinder. If you're having trouble turning the key in the ignition, it's possible that the cylinder is worn out or damaged. A professional will need to diagnose and repair it.
Anti-Theft System Activation
Some cars have anti-theft systems that can prevent the car keys from working if they are triggered. Check your owner's manual for instructions on how to reset the system. However, maybe attempt this step as a last resort and after thoroughly exhausting all other steps.
If the Locks Are the Problem
If there is an electrical or mechanical issue with the locks that could prevent the remote from working. If none of the solutions listed above solve the problem and the remote still does not work, or if the physical key or internal buttons do not work the problem could lie with the locks. If this is the case, you will need to bring the vehicle to a reputable local locksmith.
Determine the Solution
Car key remotes can experience some issues that can stop them from operating. By checking the battery and connections and reprogramming you will like to resolve the issue with a remote that stops working. If none of these fixes work, it may be necessary to consult a professional to look at the remote, or possibly an issue with the locks themselves.
