2019 rav-4 smart entry disabling

Recommended Posts

After reading up on how these smart entry systems are being easily fooled, I've become a little concerned about the security of my vehicle. The manual seems to imply that the Smart entry system can only be switched off by a dealer (Option C in the Vehicle customisation options). So I purchased a Faraday cage pouch, thinking that was the only way to protect the vehicle. I have now gone into the Vehicle customisation options in the car and found 'Disable Smart Entry' as the last entry in the set of vehicle options. So it can be switched off.

Once the system is disabled the 'unlock' button on the remote has to be pressed to gain entry into the car. No big deal. Unfortunately, it also means that 'push Start button and drive away' is also disabled. The manual does describe what now needs to be done (you are also given the same information on the car screen after Smart entry is disabled), but it is hidden away in a section labelled 'What to do if your key doesn't work'. It turns out that to start the car you have to physically touch the start button with the key while pressing the brake pedal. It then carries on as normal. Stopping it is the same as ever, with a button press. If I find this becomes a chore, I suppose I've always got the pouch to use.

I too have become concerned about this so i've gone as far as buying a couple of pouches to put the main fob and the spare fob when at home.

I'm not going to do anything more than that to be honest!

I do have a Corolla hybrid but the challenge between the your car and my car is no different.

you can also disable the fob from sending a signal via a key press sequence so there is no signal for criminals to relay. It will also extend the Battery life of that in your fob.

Hi Scott.

You seem an intelligent man to me and always give accurate and informative answers.

In your opinion do the Faraday Pouches work, i.e. do they stop the signal from the key, stop/start system stop your signal being amplified at the front door should a thief be trying to steal the car.

Many regards, Mike.

Hi Mike,

In theory what they do is prevent a signal from escaping from the pouch & therefore unable to be boosted/relayed by people stealing vehicles.

I don't claim to be an expert nor have I used any but from what I have read it seems that, like in most things, there are good & bad ones available for sale (also, that they have to be used correctly i.e. fully closed so that no signal can escape at any point). As I am known for believing in redundancy/backups I would probably disable the key fob sending via the key press sequence & then put in a Faraday pouch/biscuit tin etc. ... 😛

When I bought my latest Avensis I deliberately went for a lower spec. with a mechanical key rather than a smart fob (my previous T Spirit had smart fob but not one that you could stop sending via a key press sequence).

There is one easy way to test the pouches. Just put the key into one and try to get into your own car. When the car fails to open, take the key out of the pouch and open the car as normal. That is what I did and it worked perfectly. I'm satisfied they do what they say they do. I bought a pair from Amazon for a fiver. Just checked the reviews first to make sure they were OK. On one pouch with some negative reviews it was because that particular pouch had two pockets inside, one protected and the other not. Some people were using the wrong bit.

Hi Les.

May I say a very good answer from you and an obvious test that I overlooked.

Regards, Mike.

I was an automotive test engineer in another life.😊

I've used the key sequence to disable the fob for some time on my current and previous Toyotas (Toyota actually call it something like "Battery saver").  This has worked on a Gen 3 Prius, Gen 4 Prius and my current Gen 5 RAV4,

First lock or double lock the car.  Then, while pressing and holding the lock button, press the unlock button twice.  The little red light on the key gives two double flashes to confirm.  I just look for this to confirm it's worked, and it's become an automatic habit.  Easy enough to double check if in any doubt - put a hand in the handle and if the car doesn't unlock, it's worked.

It does mean you have to press a key on the fob to get into the car next time, but that's no problem (to me, anyway).

I've also put the spare key into battery saver mode.

A £90,000 Range Rover was recently stolen in my area while the key was said to be inside a Faraday pouch, it was suspected either the pouch was not sufficiently good quality or the spare key had not been protected or disabled.

Well I've tested the pouch I got today via Amazon and they work as expected, the car doesn't unlock/lock when pressing the buttons when in the pouch so it certainly won't unlock/start the car with any relay attacks.

The spare key is in another pouch so come at me thieves 😂

Obviously if they break into the house to get the keys then no pouch will stop that 😉
