How to Lock Your Car and Why

I locked my car --- as I walked away I heard my car door unlock I went back and locked my car again three times. I looked around and the re were two guys sitting in a car in the fire lane next to the store. When I
looked straight at the m the y did not unlock my car again.

How to lock your car safely -

While traveling, my son stopped at a roadside park. He came out to his car
less than 4-5 minutes later and found someone had gotten into his car,

and stolen his cell phone, laptop computer, GPS navigator
briefcase.....you name it...

He called the police and since the re were no signs of his car being
broken into - the police told him that the re is a device that robbers
are using now to clone your security code when you lock your doors on
your car using your key-chain locking device..

They sit a distance away and watch for the ir next victim. They know you are going inside of the store, restaurant, or bathroom and have a few minutes to
steal and run. The police officer said to manually lock your car
door-by hitting the lock button inside the car, that way if the re is
someone sitting in a parking lot watching for the ir next victim it
will not be you.

When you hit the lock button on your car upon exiting...it does not send the security code, but if you walk away and use the door lock on your key
chain - it sends the code through the airwaves where it can be stolen.

Something totally new to us...and real.

Be aware of this and please pass this note on...look how many times we all lock our doors with our remote...just to be sure we remembered to lock
the m....and bingo someone has our code...and whatever was in the
car...can be stolen.

 

For those with security systems, this will not arm the system though will it?

 

Thats why i always lock it by hand. I only use the keyfob to unlock it.

 

x2 Force of habit to hit the lock button on the door when I get out. Never really thought of it being a good habit to get into but I guess now it is.

 

This won't work on our '05 VW TDI Beetle and TDI Jetta... Ya' can't lock the door w/o the keyfob. Yes, you can lock it if you're IN the car but it is programmed to not allow you to lock the doors w/o using the fob from the outside.. This positively keeps from locking BOTH set of keys on the inside...

I think I could come up with an interesting time for some thieves if I knew what they were up to... It might require some professional cleaning of the inside afterwards...

Well, this sounds like BS to me... All modern systems use 2 sets of rolling codes. The lock code will only allow you to lock the vehicle. So they are invited to steal it.
The unlock code is completely different and can not be deducted or calculated from the lock code.
The unlock code changes every time the unlock button is pushed- and the car and the fob start negotiating. (Exchanging secret phrases, until the car is convinced that the fob is the real fob. )

What happens a lot over here is that thieves use a jamming device that will prevent your car from locking because it interrupts the connection between your car and the fob. If you don't look for the lights you assume that the car is locked. They also use a sound chip that will emit a door lock sound.

I have heard this same thing a few times before. I also heard about the original post and that is the reason for the rolling codes and different codes for lock and unlock. The earlier old style alarms only used a single code and thieves had a field day with them.
The same holds true for garage door openers. As long as you have a digital style remote, they roll through something like 1 billion different codes to make it impossible for a thief to randomly open a door.

Read this. What you got in your email was 99.99999999% crap. Alipine is correct and you have nothing to worry about. Go ahead and use the fob.

 

Thanks for the update...I was hoping someone would know for sure.

I think I need to get my eyes checked.

 

If you have a factory installed alarm in Buick, Volvo, or Dodge the alarm is activated by either the keyfob lock, locking the door with the key from the outside, or manual locking from the inside. It is disarmed by unlocking with the key on the outside or using the keyfob.

 

I posted this up at work last week and somebody snoped it. It's an old concern for early 90's vehicles. Late 90's, most went to a type of frequency hop.

 

I had seen this posted before. Lock it with the key and you'll be golden.

 

not a problem if you dont have a key fob to use......
