Theft prevention

Mike we are on the same page as far as stolen art and violins. Lots of folks out there with money and secret museums and galleries.

I guess I jumped to a conclusion that along with keyless ignition went keyless doors.

There was a post going around on facebook about thieves putting a penny or dime in the passenger side handle. It is supposed to keep the passenger door from locking with the FOB. If no one is using the passenger door, then the driver doesn’t know it is there.

I have my doubts about that though. If I am out alone, I only press the FOB button once for the drivers door only so I don’t see how that would work.

Many people, my wife included, put their valuables in the trunk. Thieves often find it easy to pry the trunk open without setting off the alarm. When we go hiking we carry only the essentials with us and leave nothing of value in the car.

Today’ security systems now also have the trunk or hatch wired into the anti-theft systems.

"There was a post going around on facebook about thieves putting a penny or dime in the passenger side handle. It is supposed to keep the passenger door from locking with the FOB....I have my doubts about that though."

To think that something questionable or just plain…wrong…could be on Facebook is simply… unthinkable! Everyone knows that if you see something on Facebook, it has to be true…

:wink:

For some reality on the topic, take a look at:

Ase, Barky, I thought of that, but I'm not familiar with any new car that doesn't have a key as a backup.

My wifes 07 Lexus has keyless ignition and keyless entry. The vehicle has no key for backup. Just the fob…nothing else.

Ase, Barky, I thought of that, but I’m not familiar with any new car that doesn’t have a key as a backup. Can anybody name one?

As far as I know there’s always a key as a backup, but often times it involves snapping it out of the key fob and then reassembling it, or carrying a separate key altogether, thereby completely negating the idea of keyless entry in the first place.

I think every car I’ve had that was 1995 or newer had a key fob for entering and exiting. It’s not new.

When I was a teen, our bus stop was outside the house of a man that worked for Budweiser. He had a company car, Ford Maverick, with the Bud logo on the doors. Someone used a crowbar on the trunk more than once. He finally put a sign on the trunk lid that said there was no beer in the car.

MikeInNH: My oldest Son was moving into an apartment. The small U-Haul was parked at his front door so he parked his POS Honda in back. Someone smashed the driver’s side window and pried out the 12 year old OEM non-functional radio. None of the doors were locked!!!

This is sort of funny and disturbing on several levels… People buy a tech laden vehicle for its gizmos n gadgets n FOBs n Screens these days. I saw this computer driven nightmare coming long ago. Anyways…people who have cars with FOBs…will very likely never and I mean never ever use thier car key to unlock the car. I cant cover all the “whys” of all that…but it ain’t happenin. One instance I can think of is a 11’ Infiniti G37…the key is hidden inside the FOB and has to be slid out and you have this tiny little spindly “emergency key” in your hand…sure you could use it…but how many people will do this for fear of Hacker Thieves they don’t even believe exist ? None…that’s how many.

The newest vehicle FOB’s dont function the same as the keyless entry remotes of yesterday…the vehicle and FOB talk to each other without any input from the driver or user… Im thinking this new problem is feeding this latest of computer savvy criminals.

The other disturbing thing is this… If you have the computer knowledge and skills to build this code catching device… You have the skills to make a good living. So what is wrong in this picture is definitely multi level.

Kids these days were born with tech us Old Heads could only dream of back in the day…it opens the door (Pun intended) to an entirely new type of crime…no less worrisome…and in ways much more worrisome. I had to go to school to learn computers n networking and such…these kids seem to already know this stuff right off the door. Computers are just something they were born with…this will lead to scary places. Places where you suddenly no longer own your own home…or your bank account…

Im gonna go check on the money in my mattress now…

Blackbird

Im gonna go check on the money in my mattress now...
And use it to buy gold.

I have an FOB and use my key much more often than the FOB.
I must be change-resistant! :smiley:

Then don’t buy a keyless Lexus or Toyota. There is no key.

No backup?

the same mountainbike: The backup is what thieves used in the old days. A brick through the window! I carry a key in my wallet. The only places left to use it are driver’s door and ignition switch.

If I understand Mike correctly, there’s no key at all. I wouldn’t want that.
I carry a spare key in my pocket with my loose change.

No backup. Our Lexus IS now 9 years old and no issues so far. You get a warning the battery in the fob needs replacing long before it won’t work. Wife loves the convenience of the system.

I guess I’ll have to cross Lexus off my “when I win the lottery” list!
Bummer. I like Lexus.

Hackers are apparently building a device that they place under the car that will detect and store the signal that your FOB transmits when you unlock the car.

Like George, my first thought went to my garage door opener. Even it uses rolling code technology to deter someone from cloning the last transmission. Even I can’t open the door if they get out of sync for some reason. I have to initiate a re-sync operation so they are both seeded with the new number.

It would be a huge oversight (sin if done on purpose) if they did not use a digital data stream with synchronized rolling code…

most keyless entry/start cars do have a backup key hidden in the remote. There’s a little button somewhere that you press to eject the key. This will unlock the driver side door. Once you’re inside the car, the remote’s battery is no longer needed as the polling signal from the car is enough to energize the RFID chip in the remote and tell the car that it’s OK to start.
