How Stuff Works

The locks on modern cars, Bentleys for sure, cannot be picked. Then, of course we have the keyless cars. This drives them all mad in a certain part of the country that I won't mention...
 
Well, I'm no technical expert but they are individually programmed "keys" which contain sensors so that the car knows when its driver is approaching the car and when he or she is inside. If you keep the "key" in your pocket or handbag the sensors transmit the signal and unlock the door when you press the handle. Once inside, all the driver has to do is release the hand-brake, push a button and drive off.

As well as meaning that there's no more fumbling for keys outside in the cold or rain, the system is more secure than the traditional key - while there are a thousand different ways to cut a mechanical key, the fob system involves about four billion codes that are continuously changing. That means even if a thief intercepts your code, they won't be able to enter because the vehicle has already changed codes since the last time you entered it.

Clever, eh?
 
"Is this your vehicle, Madam? Would you open it for me?"

"Of course, officer. Just hold on a tick while I drop me kecks and have a rummage around for the... oops! Excuse me, it seems to have become lodged in... aah, that's better. Now, where were we?"
 
The plague is lifting, dearest. Mostly (or should that be moistly?) the nose and throat being the naughty bits now. I'm hoping to lose the bell round my neck by the end of the week, too.
 
Brian - what about when we girlies go out and our handbags are bigger than our knickers :o B) ( as opposed to the usual nights out in Briget Jones style knicks! B) )

I still reckon that any 10-year-old from Salford could have the radio out within 30 seconds!
