I have been having an issues since taking possession of my new CX-30 where my driver door will not unlock by the sensor on the back of the handle. This has never occurred on any other door the rear tailgate works perfectly and so does the passenger door. Any one also having this issues.

Are you touching the front of the handle at the same time?

Not that I know of I’m going to be vigilant on it. Seems to be intermittent and only affect the driver door. Will keep this updated. I knoticed it also seems to be an issue with some of the new Mazda 3’s

The system may not operate normally under the following conditions.
You touch the sensing area of the door lock touch sensor and the sensing area of the door release touch sensor at the same time.

I have been more vigilant and yes it is still not working properly. I am going to try to replace the batteries in the key fob and see if that helps. I am not pressing the loch button at the same time as the back of the handle.

Yes I’m familiar with the user manual and I am not touching both the rear of the handle and the lock button.

I figured out my issue it happens because someone else is touching the sensor on the other side of the car

That's correct. If your passenger is touching the sensor on their side, the driver's side will not unlock via the sensor.

Have been having the same issue with the driver door not unlocking if I place my hand inside the handle. This occurred about 20% of the time so it was frustrating to find out what the issue was. The dealer could not help resolve the issue and even replaced the door handle as part of the guarantee. But, I found out recently that if I try to unlock the driver door with my hand inside the handle and doesn't work, I slightly touch my leg (to ground myself) and then it works 100% of the time. So, my thinking is that my hand was not making an electric current to unlock the door, but touching my leg somehow enabled my hand to unlock the door by conducting electricity. Does this make sense?

You don't even need to stick you hand inside the handle. You can touch the handle and it will unlock.

It makes some sense although it is a bit strange. Maybe there is a technology on you or a piece of clothing that interferes? I haven't had any issues unlocking without touching legs. You should test this hypothesis by trying to unlock your car naked. ;) "What is that person doing running around his Mazda naked touching it? Oh, they are just testing the unlock feature". :LOL:

Well, that's dumb. I am a Techie and like electronics but NOT when it gets in the way.
There's nothing wrong with two people entering the same car at the same time :rolleyes:

When I teach this system to technicians, we have a discussion about how these door locks operate. This BTW is more of the Toyota technology and strategy in the car. First, you have to be patient with the system. The car doesn't look for a key being present until it see's the handle input. Then it takes around 1/4 to 1/3rd of a second for the command to the door lock actuator to be made and the motor respond and unlock the door. If you pull on the handle immediately when you grab it, the motor will fail to move the unlock lever in the latch assembly. So you have to touch the handle and wait to see the response before you pull on the handle. The reason the car can be finicky when two people try to open the doors at the same time is the engineers don't want someone who shouldn't be getting into the car to try and open the passenger's side when the driver is opening their door. So the default is, the drivers door handle unlocks the drivers door. The passenger side door handle unlocks all of the doors IF it is sensed first. So I just either go to the passengers door and open the car when we get to it, wait for my wife who has her own key to open the passengers side first, or I open my door and then unlock the passengers side from the inside. This is something that can be changed in the personality settings and the drivers door input can be set to open all of the doors but you need to understand the potential risk with doing that.

I think it's more about thinking through and understanding the logic that the design team went through in getting to the finished system. Then you can adapt your thinking to theirs and make the best use of the system.

There is an option you can set to unlock all doors at the same time. So, if anyone pulls on a handle, all doors unlock simultaneously. Aside from carjacking, I can't think of a good reason no to have this option on. In my CX, all doors open when one is.
