Starting a car when you have a broken key can be a challenging task, but it is not impossible. There are several methods that might help you get your vehicle running even in such a predicament. It’s important to note that these solutions should only be applied to vehicles you own or have rightful permission to operate.
In this guide on how to start a car with a broken key, we’ll explore safe and legal techniques that can help you start your car, as well as precautions to take to avoid long-term damage to your vehicle’s ignition system.
What is a Broken Key?
A broken key is a key that has either snapped or sustained damage on its surface. This can make it unusable in the conventional manner of inserting the key into the ignition and turning it to start the car. A broken key can happen due to wear and tear, accidental damage, or attempted theft.
It’s important to address a broken key as soon as possible as attempting to start your car with a damaged key could lead to further damage to your vehicle’s ignition system.
Why is it Important to Handle a Broken Key Carefully?
A broken key can cause serious damage to your vehicle’s ignition system if not handled carefully. Attempting to start the car with a damaged or broken key could result in scratches or dents on your vehicle’s ignition cylinder, which can be expensive and time-consuming to fix. Moreover, it may also cause harm to the internal components of the ignition system, leading to costly repairs.
Therefore, it’s crucial to address a broken key promptly and use caution when trying to start your car with it.
8 Methods on How to Start a Car With a Broken Key
Method 1: Use Your Spare Key
The simplest solution to start your car if you have a broken key is to use your spare key. Most vehicle manufacturers include a spare key with the car purchase, and it is typically stored in a safe place within your home or carried in your wallet for emergencies like this. Using the spare key is the most straightforward and damage-free method to gain access to your vehicle and start it.
If you do not have a spare key or cannot locate it, consider contacting your dealership or a locksmith to obtain a replacement. Always make it a habit to have a spare key ready to prevent similar issues in the future.
Method 2: Use a Temporary Key
If you do not have a spare key, you can create a temporary key using your broken key. To do this, you will need to use pliers or wire cutters to break off the plastic casing of the key and expose the metal part. Then, insert the metal portion into the ignition and jiggle it around until it catches onto the tumblers. Once it does, turn the makeshift key to start your car.
While this method may work temporarily, it’s important to note that it could cause damage to your ignition system in the long run. Therefore, it’s best to use this as a last resort and get a spare key or replacement key made as soon as possible.
Method 3: Use an Auto Jumper Box
In situations where your key is broken and inaccessible, using an auto jumper box, also known as a portable jump starter, can help start your vehicle. This device can be particularly useful if the car’s electronics use a push-to-start button rather than a traditional key-turn ignition. To use an auto jumper box, open the car’s hood and connect the jumper cables from the device to your car battery, following the manufacturer’s instructions for the correct polarity.
Once connected, turn on the jumper box and attempt to start your car using its starting button or switch. An auto jumper box can provide the necessary power to start the car without engaging the ignition lock. However, exercise caution and ensure all connections are secure to avoid short circuits or battery damage. This method is more suitable in emergencies, and it’s prudent to have your key issue resolved promptly following this workaround.
Method 4: Tap the Key with a Hammer
In some cases, a key may get stuck in the ignition due to internal damage or debris. If this happens, tapping the key lightly with a hammer while trying to turn it may help dislodge it and start your car. However, this should be done carefully and gently as too much force could break off the key inside the ignition, causing further issues.
It’s essential to note that this method should not be used if the key is visibly bent or broken, as it could cause further damage.
Method 5: Use a Lock Pick Set
If you have some knowledge and experience with lock picking, you can use a lock pick set to start your car. This method involves manipulating the pins in the ignition cylinder by inserting a tension wrench and a pick into the lock. However, this technique requires patience and skill and should only be attempted by those who are proficient in lock picking.
Using this method on newer car models may also prove challenging as they often have advanced electronic locking systems that are difficult to bypass without specialized tools.
Method 6: Call for Roadside Assistance
If you’re unable to start your car, consider calling for roadside assistance. Many auto insurance companies offer this service as part of their plans, and it can be a convenient and safe option if you have no other means to start your vehicle. A trained professional will arrive at the scene and help you get into your car or tow it to a nearby mechanic if necessary.
If you do not have roadside assistance, consider reaching out to a friend or family member for help. The key is to not panic and seek assistance from someone who can provide a solution.
Method 7: Use a Slim Jim
A slim jim is a thin strip of metal that can be used to unlock a car door from the outside. This method only works for older vehicles with manual lock systems and can be tricky to use. It’s best to have a professional, such as a locksmith or roadside assistance personnel, handle this method to avoid causing damage to your car.
However, even with professional help, this method may not work on newer cars with advanced electronic locks.
Method 8: Replace the Ignition Cylinder
If all else fails, replacing the ignition cylinder may be necessary. This involves removing the old damaged cylinder and installing a new one that matches your key. While it may be an expensive option, it ensures that you can start your car with ease and without risking further damage.
Following these methods on how to start a car with a broken key should help you start your car with a broken key. However, remember to address the root cause of the issue and get a replacement or spare key made as soon as possible. Prevention is always better than finding solutions when faced with an unexpected problem.
