Unlock car from mobile

May not work for all car models

What if your duplicate keys are back at home and you are away with your car when you forget your keys inside your car, or worser still, lose them??

Obviously, the remote of your duplicate key has a very limited range and thus cannot work when you are away from home. Don’t worry, this trick can unlock your car and get you your keys.

Requirements for this trick:

1. Your car must have central locking with remote entry system (sometimes called power door lock)
2. Duplicate keys with another person, maybe at home
3. You must have a Mobile with you.

If you meet all the above requirements, continue as follows:

  1. With your mobile, call the person who has the duplicate keys of your car. For example,  if your duplicate keys are at your home, you can call your wife or servant or whomsoever is near the keys.
  2. Tell the person to get the duplicate keys and hold its remote near the mic of their phone/mobile.
  3. While they do this, set your mobile to speaker phone and get near the steering side of your car (that is where the central locking system is)
  4. Next, tell the person to press the unlock button on the duplicate keys while holding it near their phone/mobile. This may not work immediately, so tell them to tap the button continuously till your car unlocks.

It is that Easy!!!

How does this work??

Well, the uniquely coded radio frequencies emitted by the remote of your keys are transferred from that persons’ phone/mobile to yours. But because your phone was near the main unit inside the car, it caught those radio waves and unlocked your car.

Spy with your mobile

Now you can spy on anyone using your cell phone.

Hide your cell phone in a room, like under the table or somewhere, and then enjoy listening the conversation in that room!

Just do the following:

Radios – Digital, Analogue and Internet explained

With the increasing popularity of digital and internet radios, the days of manually tuning into radio stations are numbered. Everyone is familiar with the annoyance of having to precisely turn the dial on old analogue radios to find the right station. Even when the right station has been found, it is often accompanied by the delightful sound of static. So what makes these newer radio technologies so much better? Here is a breakdown of the differences between analogue, digital and internet radio.

Analogue

Analogue radio transmission is simply a way of sending information via continuous radio waves. Multiple analogue signals can be transmitted simultaneously via a method called modulation. There are two popular forms of modulation that most people will be familiar with: FM (frequency modulation) and AM (amplitude modulation).

Through this use of modulation, people can ‘tune’ their radios to a specific frequency or amplitude to listen to a radio station. This type of radio transmission has been used widely and successfully since the early 20th century, but nowadays however, other forms of radio transmission such as digital are becoming more popular.

The main problem with analogue signals is their tendency to lose signal strength and quality. When radio stations begin to sound distorted or ‘fuzzy’, it is usually down to the fact that the signal has a lot of noise i.e. the original signal has degraded.

Digital

DAB or digital audio broadcasting is becoming more and more popular with radio listeners. Instead of the continuous radio waves used for analogue signals, digital signals are truncated or cut-off at specific points to indicate either 1’s or 0’s. These strings of 1’s and 0’s hold the information of the transmission. It may sound a little complicated, but digital transmissions have a much greater ability to resist background noise and other distortions, meaning better sound quality for the listener.

One of the great things about DAB radios is they tend to be much more user friendly than analogue radios.

Instead of having to fiddle with tuning dials and frequency indicators, most digital radios have great LCD displays that allow the user to clearly see and select channels.

Digital radios usually have a wide range of useful functions too. Some DAB radios allow the listener to pause, rewind and record live radio broadcasts to listen to them later. This can be great for people who don’t want to miss their favourite shows when busy with other things.

Internet

Instead of receiving analogue or digital radio transmissions, internet radios can be connected to the user’s own Wi-Fi network. One of the best things about internet radio is that it gives users the choice of many thousands of radio stations instead of the mere handful that conventional radio offers. Due to the vast number of stations available, listeners are bound to find something they like.

Another great feature of internet radios is that they allow the user to listen to podcasts and access pre-recorded shows when they like. Some internet radios also allow users to play their own music from their computers through the radio, so listeners aren’t just limited to the radio stations. It is worth remembering that a home internet connection is required to use internet radio.

With DAB and internet radios having so many great benefits and features, it’s easy to see why they are rapidly taking over from antiquated analogue radios. From greater usability to the massive range of stations available, it looks as though the next generation of radios have finally arrived.
