![]() If it's the right kind of lock, it should come right open. Most pin systems are spring-loaded, and the ridges of the keys press against the corresponding pins, which then unlock the lock. House Door Method #1: Use a Bump Keyīump keys are specially crafted keys that are used to unlock pin based locking systems, which are used on the vast majority of homes. Older locks are typically easier to open without a key, while newer ones can be a bit more tricky. Unlocking a House Door Without a Keyįor locks on houses and other types of doors, the method depends on the type of lock. However, if you feel like you're in danger staying where you are, they may be more willing to help. While plenty of officers have the tools to help you, it's never a high priority, and you could be wasting their valuable time by calling in. Thankfully, I was dealing with an organization I knew, and they weren't busy at the time.Ĭalling the police is another possibility, but not one I would try unless you have no other options. I called the public safety department, and an officer came and opened my door using a car opener toolkit. I recently locked my keys in my truck when I was visiting my old university. Car Door Method #9: Use Police/Security Assistance Even if you don't have the service, you can call in, become a member, and have someone at your car that same day. If you have the service already, you can call and have someone come and help you within half an hour. AAA is probably the most well-known car assistance provider in the nation. If all else fails, there's nothing wrong with getting a little help. Let us know in the comments if you have any luck. If you want to find out whether or not it works, the best way to do so is to try it out. The pressure created in the ball will force your car to unlock.or so they say.Īs you can see, there are plenty of arguments on both sides of the debate around this method. Place the tennis ball, with the hole on top of the keyhole, and push. ![]() You'll need to make a hole in the ball, so a heated electric drill or screwdriver would do the trick. In one of the coolest (and most debated) methods for unlocking a car door, a simple tennis ball could do the trick. Car Door Method #7: The Hail Mary (AKA Tennis Ball) Put a spare car key in there and hide it under your bumper. If you don't want to get locked out again, you could also invest in some magnetic key holders. Also - make sure not to keep it in your trunk! What tools and methods work for you depend on what type of locks your car has, so make sure to check that against the methods above before buying anything. ![]() Or buy a set of wedges or an inflatable wedge, and long reach tool. If you have a habit of locking yourself out of the car, you could also invest in a complete lockout tool kit or a long reach tool kit. You should also call around and ask friends and family if they happen to have any of these tools themselves. That automated button-mashing solenoid, shown in the video below, allowed Cesare to assemble enough data to find patterns in the seemingly-random numbers, cutting the number of possible unlock codes from around 43 million to around 12,500.For a lot of these methods, you could potentially make due with things around your house or already in your toolbox. To find the cryptographic vulnerability he exploited, Cesare developed an ingenius hack in its own right: He built a small robot to push his key fob's button thousands of times and listened to the radio codes it transmitted. But Cesare believes his attack is the first to actually break the encryption of a car's wireless unlocking mechanism since Israel and Belgian researchers cracked the widely-used Keeloq wireless entry cipher seven years ago. Three years ago Swiss researchers found they could break into and even start cars wirelessly by triggering an unsuspecting victim's key fob and reproducing the signal with their own antenna in what's known as a "replay" attack. "But they won't be getting it from me."Ĭesare isn't the first to wirelessly break into cars. "Criminals could hire researchers to replicate this attack," he says. For that reason he's declined to make his code or tools available to the public for fear of enabling less technically-skilled thieves. ![]() Ultimately, Cesare says it may be too late to protect the vulnerable generation of cars he's discovered, and he intends his findings to instead serve as a warning to automakers for future models. In fact it would often trigger the "panic" alarm for many modern cars. ![]() He suggests manually locking the car in any instance when an eavesdropper might be able to pick up the fob's signal.īut he admits that kind of paranoia is hardly a satisfying fix. Cesare suggests that limitation could serve as a form of band-aid protection: Anyone concerned about wireless car burglars could avoid using the fob in public. ![]()
