There are several methods you can try to start your car without a key fob in case of an emergency: the screwdriver-hammer method, hotwiring the engine, or looking for the red coil wire.
You can also try to use the mobile app (if applicable) or locate the secret switch that’s usually located in the steering column.
Some of these solutions may cause harm to your car. Others need substantial automotive understanding. It’s always best to seek the help of a professional when dealing with these things.
Key fobs have been around for a long time一and with good reason. Aside from keeping vehicles safe from unwanted entry, they’re also easier to use than keys because they can lock and unlock doors with just a press of a button. On top of that, they’re easy to reprogram.
Unfortunately, using this handheld device can come with some issues, one being it’s easy to misplace because of its size. If you lost your key fob, don’t worry. Check out some of the hacks below on how to start a car without a key fob.
Use the Screwdriver-Hammer Method
A screwdriver and hammer can help you disable the lock pins on the ignition lock cylinder.
You can get in your car without a key fob, provided that you have the right tools. Once you’ve unlocked the doors, the next challenge is starting the car without the keys.
A screwdriver and hammer can help you disable the lock pins on the ignition lock cylinder. Simply insert the screwdriver into where the key should go until it’s deep enough to penetrate the inner flaps inside the cylinder. Then, try to turn the ignition. But be careful. This method will damage the key mechanism, requiring you to replace it.
Movie scenes where thieves pull out a couple of wires from under the dash to drive vehicles actually have some truth to them.
Hotwiring is a popular hack that works on older vehicles. It involves removing the plastic cover under the steering wheel and cutting the battery and power wires before twisting and connecting them.
Look for the Red Coil Wire
In most older vehicles, connecting the red coil wire to the positive battery terminal using a jump starter cable can start a car without a key. If you’re thinking about trying this method, keep in mind that you need to have extensive knowledge of your vehicle’s wiring system to do it.
Use the Mobile App
Some vehicles are accessible through a mobile app, which can come in handy when the key fob is disabled.
Some vehicles are accessible through a mobile app, which can come in handy when the key fob is disabled. But if your car doesn’t have an advanced remote unlocking system, requesting road assistance is probably your best shot at getting your daily driver running.
Locate the Secret Switch
A push start button in replacement of the traditional ignition lock cylinder has remained a popular feature in a lot of late-model vehicles. And if your car has this setup, methods like hotwiring or using jumper cables might not do the trick if you don’t have your key fob.
Fortunately, many automakers have a fail-safe measure that can get you out of this problem. They add a secret switch that’s usually located in the steering column to their models.
The switch usually has a plastic lid. If you remove the cover, you’ll see a key fob-like interface where you can use the screwdriver and hammer method to kickstart the ignition.
Things to Keep In Mind
While these methods work, they often come with risks. Some of these options can damage your vehicle to the point that you’d need to replace a part or two. Others require extensive automotive knowledge to pull off. Lastly, remember that it’s always best to seek help from a trained professional when dealing with car problems to ensure that all repair steps and protocols are followed correctly.
You can get a replacement key fob by contacting your dealer or a locksmith or getting aftermarket replacement keys. Replacements usually cost between $25 and $450, while smart keys can cost around $800 or higher.
You can have the key fob replaced as long as you have the metal key. Programming a new key fob ranges from $50 to $100, while some dealerships do it for free or charge for little. If you lost both the fob and the key, then you’ll need to get a replacement.
Can I Program a Replacement Key Fob Myself?
Some cars are equipped with onboard programming, meaning you can program new key fobs or keyless remotes by yourself. Check the owner’s manual for more information on how to. It’s a relatively simple and easy process that doesn’t take much time.
