Keyless Lock/Unlock

[Chris Stringer]

Hi there,

Has anyone else had issues with the keyless lock/unlock on their Alphard. My wife and I have just been to Devon for a week, and at times we had to resort to using the mechanical key to lock/unlock the vehicle. We changed the battery in both keys, but even after that we still intermittently encountered difficulties using the keyless lock/unlock system.

Thanks 

Chris

Fit a new battery to the smart fob perhaps ?

[Chris Stringer]

We did that, but it didn't help.

Has it had a campervan conversation?

Is it still doing this?

I ask because, when in in London, there's a particular shopping car park that my alphard will refuse to work with the fob.

Even the door lock unlock sensors will not work and i have to manually use key. 

 

I think there is some jamming technology in the area.

Hi Chris, 

   The reason why I asked if it had  campervan conversion is I had intermittent problems with my remote keyfob not working. 

   The buttons wouldn't work, no keyless entry nothing! 

   Then I would try another time and they worked perfect!?

    After a lot of frustrating scratching my head and changing the key fob batteries, I found it only worked perfectly at night or indoors. 

   After a bit of research I found out that the Japanese cars use a different frequency on their remote keyfobs than the UK.

    I have a solar panel on my conversion and the solar controller (MPPT) gives out a radio frequency that interferes with the keyless receiver on the Alphard. 

    I think there's other electronic devices about that give out a radio frequency, possibly in that London carpark, that would interfere with your Alphard but not and British sold cars maybe?

    Anyway, I relocated my solar controller and it works perfectly now.

   Hope this helps.

Fascinating !

 

You never know.

Wow!

As they say, you learn something new every day!

Who would have thought a solar contoller would emit significant enough radio waves to cause that interference!
