Any idea if these emergency techniques work?

A friend Asif Adheni sent this. Do not know if they actually work.

1. *Emergency Services:*

_If you find yourself out of the coverage area of your mobile network and there is an emergency, just dial 112 and your mobile will establish your contact with any existing network in that area! Surprisingly, the emergency number 112 can be dialed even if the keypad is locked!_
_*This works on all phones worldwide and is free, too!!*_

2. *Locked Your Keys In The Car:*

_If you lock your remote keyless car keys in the car and the spare keys are at home, call someone at home on their mobile phone from your cell phone. Hold your cell phone about a foot from your car door and have the person at your home press the unlock button on the spare key, holding it near the mobile phone on his/ her end. Your car will unlock, even if you are thousands of miles away!!_

3. *In Case of Mobile Phone Battery Flat:*

_All cell phones have Hidden Battery Power._
_To activate, press the keys *3370# (remember the asterisk). Do this when the phone is almost dead. Your mobile will restart in a special way with this new reserve and it will show a 50% increase in battery life. This reserve will be recharged when you charge your handphone next time. This secret is in the fine print in most phone manuals, which we often skip without realizing!_

4. *Disabling A STOLEN Mobile:*

_To check your mobile phone's serial number, key in following digits on your phone: *#06#. A 15 digits code will appear on the screen that is unique to your handset_. _Write it down and keep it somewhere safe._ _If your handphone is ever stolen, phone your service provider and give them this code._ _They will then be able to block your handset so even if the SIM is changed, your handphone will be totally useless_. _Maybe you don't get your phone back but it can't be used/ resold either._
_This secret is in the fine print of most mobile phone manuals_. _It was created for the very purpose of trying to prevent phones from being stolen._

5. *ATM PIN Number Reversal:*

_If you ever be forced by a robber to withdraw money from an ATM machine, you can notify the police by entering your PIN # in reverse order. For example, if your PIN Number is 1234 but you should instead put 4321. The ATM system recognizes that your PIN # is backwards from the ATM card you placed in the machine. The machine will still give you the money you requested for but unknown to the robber, the police will be immediately dispatched to the location. Beware all ATM’s carry this emergency sequencer by law. It is, however, seldomly used as people just don't know about it!!_ ⚠
