try new key battery.... ours didn't last long on the new Cab...

 

For the first time today my door did not automagically unlock when I grabbed the handle. Tried a couple of times, but nothing happened.

Unlocked with the key fob just fine.

Only thing I can think of is that a little earlier I had run down the windows to help keep the car cooler, then using the key fob I double pressed and held the lock button to raise the windows remotely.

Checking the manual I found that pressing the lock button twice disables the keyless go feature.

I should have pressed and held the lock button rather than double clicking it.

May not be related to your problem, but thought I'd pass it along just in case.

 

It is exactly what you said, once you pressed the lock button on the key, the car will not unlock by just putting your hand on the handle. My suggestion is never lock the car with the key button, just lock it by putting your hand on the door handle to lock it.

 

 

The only time I have this issue is if I have the key and cellphone in the same pocket. This also causes issues with my Porsche.

 

I've had tge same issue with a Keychain garage door opener. It's caused by RF interference.

 

I think the issue is that some vehicle makes used to have the user double click the fob to lock it. For some time, at least the European makes, have disabled the fob following a double click on lock.

The purpose is to disable your fob so that it cannot be spoofed/scanned and used to open the vehicle. You can and should use this when away for vacation or away from home for some time.

So the system is working exactly as intended, very few understand this is the intent of the design. I scratched my head for years on my previous car before figuring this out.

 

Make sure to do it for the spare key as well if worried about being relayed.

 

This makes sense if you used the fob. But if you used the touch sensors method to lock/unlock the doors, this wouldn't be relevant.

 

No, the double click turns the fob off, the car cannot see it to validate unlocking the door.

 

This is correct, since the key is no longer sending a signal.

 

okay. Makes sense.

 

I was about to say.

Double tapping the lock button on the FOB turns off the fob and by design, the proximity unlock.

Also a weak battery in the FOB will also exhibit some very odd behavior.

 

Isn't there supposed to be a check key battery message when it is low?

 

Supposedly!

I never got the error message but i was getting some behaviors such as touch handle, no unlock.

 

I see, that's why.
