Turning off smart entry to prevent auto theft.

Is there anyway to disable the "smart entry" system, where just having they key fob in your pocket unlocks the doors? I want to change the settings so I can only unlock the doors by physically pressing the unlock button on the key fob. But I can't figure out how to do this from the manual.

Why would I want to do this? Last night, a few blocks over from our home, several cars were broken into by thieves using signal boosters or relays. The way this works, they pick up the signal of your key fob from where it is hanging in your house (or from your pocket while you are standing in line at McDonalds or wherever), and they transmit it to your car, making your car think they have the key fob.
They were successful in unlocking three cars. This was was captured by a homeowner's security camera. But on one car they were trying to enter an alarm went off (maybe an aftermarket alarm, I'm not sure) and this scared them away before they could do much. But this was just pure luck...

One way to protect against this is to keep your key fobs in a closed tin can at home, and in a shielded sleeve or bag while you are out in about. You can buy these on Amazon. Or even just wrapping your key fob in aluminum foil would work. But, having to take the key fob in and out of a sleeve all day sounds like it would be a real pain in the neck. Just physically having to press the unlock button seems it would be the easiest way to prevent this.

If anyone know how to turn off "smart" access (which now turns out not to be so smart afterall), let me know! I'd rather have a key fob that works like a regular "old-school" remote then have to take it in and out of a faraday bag all day.

Open up the door panels and just unplug the harnesses to the smart sensors on the handle.

Problem solved

The one in a million cloning wont hurt your car because you need a physical key & you’ll have to use the slide out key every single time you enter.

Personally i’d rather they stole it than do all that

I think people are sweating this way too much. Like all things... in my view...you adapt and overcome.. not give up (ie: forego keyless entry)

FACT: cars have always been opportunistically stolen by car thieves.. for as long as there have been cars. This will always be true, and car owners must adapt to changing threats.

FACT: the method of theft advances and adapts right along with the cars. Used to be smash and hotwire... now days... that won't work.. so thieves have adapted. With the proliferation of car alarm systems years ago.. thieves learned all the ways to bypass or disable them. Used to be they could get your VIN and through a blackmarket network they could get cloned keys and just walk up and snatch your car... but that is always risky and is no longer needed in the electronic age, and manufacturers keep better control over keys and blanks now days.

If it is a concern... then you simply keep your key fob in a little RF blocking container in your pocket.... no different then modern wallets that have RFID blockers now incorporated to prevent hackers from area scanning your credit cards. The market is saturated with RF blocking containers for key fobs now days: https://www.amazon.com/s?k=rf+blocking+key+fob+holder&ref=nb_sb_noss_2

Personally, my cars are always behind a locked garage door at home.... so no issue in that regard for me. But I bet most cars are lifted (or entered to steal contents) this way in parking lots.. and so.. be prudent where you park, and who is around when you do.. and failing that.. keep your fob in an RFID blocking pouch when not in use. That way.. the only method available to them would be close proximity reading of your FOB at the time you lock your door... which honestly is a very narrow window for them to act.

Forfeiting the feature of keyless entry just denies you a valuable feature and lets the thieves win through suppression-through-theft on their part.

How about the old school hidden toggle switch? where/what wire to splice to attach the toggle switch?
Might disable the smart entry thus needs to use the physical key if there is a way, once it is switched on then the push button start will work. With this solution, I'd rather have the Faraday pouch and just take out the fob.
So, until they find a way to circumvent the snooping problem, we'll just have to make do, and deal with the inconvenience.
I think we have become too spoiled and lazy... me included.

It's also a "fact", one that thieves are quickly discovering, that keyless entry makes it faster and easier to steal cars then ever before--the gear needed is not expensive and doesn't take the skills and training that were needed to slim jim into a car and hotwire it. It's also a lot faster and easier than cloning. For thieves, "smart entry" is the next best thing to you leaving a key in the ignition.

Faraday bags or sleeves (what a poster above refers to as RF blocking containers) certainly do work as I noted in my original post. But as I noted (at least for me) needing to use one (and take the fob in and out) each time reduces the "smart entry" system from being more convenient than a traditional "push the button" remote to less convenient. And the CR-V key fob does have lock and unlock buttons that can be used manually and from a distance. So it would work great for this, if only there was way to turn off the "smart entry".

But if you look into this issue some more, you will see that this is not just another way that thieves can steal cars, similar to older methods. Smart entry makes your car significantly less secure. (Unless you are using a faraday bag--but then again, why bother--it's more hassle than it's worth at that point and and no longer a valuable feature.)

I just remembered, before the smart entry technology, we have the push button number keys on the door (instead of the physical keys).
oh, yeah, I completely forgot about that wheel lock thing....
So far I cant find anything in the web to disable the smart entry key, but there is a way to completely disable the fob

We had something like this happen around here but they were using a cloning gadget so pressing the button is what they want. You can't stop thieves if they really want it. Make sure you have good insurance and go live your life.

I had an unsettling experience this morning. I am visiting my daughter who lives in a nice rural area subdivision in PA. When I went out to my car this morning all the windows were down. I am sure we closed them the night before. What really was convincing was that the sunroof was also open. We definitely did not have it open. Nothing had been taken so it did not seem a theft attempt. I am concerned that there is some sort of electronic glitch. Any idea what might have happened? I’m a little freaked out.

Yes, when you unlock with a push button, thieves can exploit that also, but it's a lot less convenient for them. They can only intercept the single for the split-second that you push the button to unlock your car, and then they have to come back later when the car is locked. For example, if they intercept your signal when you are unlocking the car to leave the house, they have to return to your house that night to steal the car. If you are in the shopping center parking lot, it will be almost impossible for them to find you so they won't bother.

But more critically, intercepting the push button remote signal only allows the thief entry into your car--they can't use that signal to drive away with it.

The "smart entry" (no button pushing needed) signal is ALWAYS there 24/7 and so much easier to intercept if they can get close to you like (like standing behind you in line) and if they are using a high sensitivity receiver they can even grab the signal from a greater distance (like from inside your house). It's always on, so they can grab it at any time.

And once they have the signal, they have "the keys to the kingdom" -- it not only lets them enter your car--it also lets them to drive away with it by simply pushing the "start button."

Every method of securing your car has some vulnerability, but ideally we would be making things more difficult for thieves, not easier.

And it's not like this is not happening. Here is a post right here on this forum:

https://www.crvownersclub.com/threads/new-car-stolen-but-how.94530/

Here is an informative video from the NICB which I recommend everyone watch. They purshased a relay device and tested it out on 35 different types of vehicles. They were able to open 19 of them, and of these, they were able to start the engine of all but on and drive away. While they don't name brands/models, you can see in the video that one of the cars that they were able to drive away was the CR-V. They also note that some of the devices available on the market are much more powerful and more capable then the one they used.

Which is why I never lock/unlock my car with my key fob. I only lock and unlock with the door handle. And the range of the fob in this mode is extremely short range and only triggers a verification to the car that the person unlocking the door is authorized. The fobs now days are always in listen mode, but not in transmit mode until they respond to a query code. The thieves stealing fob codes are spoofing the fob into thinking they are the car so that it will transmit in response.

At home my car is always locked in my garage, so no way to access the vehicle, so no reason to try to trigger my fob to respond with a code-out.

Having an old style push button entry into your car is not guarrantee that you car is safe from those devices that "talk" to the key fob and make it open the car.

I have the old style push button entry on my 2015 CRV car key and had my car broken into about 2 years ago. No windows were broken and no signs of forced entry were found so I know they used one of those devices to get in and steel my GPS, my car registration and a little tool kit I kept in my glove box. But I at least I still have the car!

The main advantage of the push button car entry is it's inability to start the engine making it harder to steal the car. But your car may still be broken into. I thank you all for introducing me to the devices and methods to keep the key from being used to unlock the car. I might get one. At the time, I was told to keep my key in the refridgerator. I have never bothered doing that. I now keep my car in the garage.

Kids go around they pull every door handle, Hey Jim got one, they open the the doors and grab the change, off they go, repeat the same thing each night, same car Jim, Owner never learns their lesson , Same two kids say time to teach the Owner not to leave stuff around they then take the stupidest thing or things.. to finally the Owner says enough, they go buy an aftermarket alarm.

if this works for you if IF the real question is will it desable the actual Module in the car that is still active.

You can go back to the key ignition if like can you. or why get the higher end car.


Step 1
Enter your car, open the driver's-side door, unlock the door and close all the other doors on the car.
Step 2
Insert and remove the key from the ignition twice, and close and open the driver's-side door twice.

Step 3
Insert and remove the key from the ignition again, close and open the driver's-side door two more times, then insert the key into the ignition again.
Step 4
Close the driver's-side door again, cycle the key to "On" and then back to "Off," and then remove the key from the ignition.
Wait for the locks to cycle to indicate that the programming sequence is open. This is the time when you would normally program your remote. Doing nothing here will leave the transmitter unprogrammed and the remote inactive. You can open the driver's-side door to end the sequence and complete the disabling of the remote.

A while back there were news articles about how easy it is to gain control of a modern vehicle even as it drives down the road. Gotta wonder how long until someone offs someone with that technology.
