Chris Stringer Posted April 27, 2023 Share Posted April 27, 2023 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 Quote Link to comment Share on other sites More sharing options...

Thanks Chris Fit a new battery to the smart fob perhaps ? Quote Link to comment Share on other sites More sharing options...
Chris Stringer Posted April 28, 2023 Author Share Posted April 28, 2023 We did that, but it didn't help. Quote Link to comment Share on other sites More sharing options...
Danny Neil Posted September 9 Share Posted September 9 Has it had a campervan conversation? Quote Link to comment Share on other sites More sharing options...
Chris.ac Posted September 12 Share Posted September 12 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.

Danny Neil Posted September 12 Share Posted September 12 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. Quote Link to comment Share on other sites More sharing options...

BigNev Posted September 12 Share Posted September 12 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! Quote Link to comment Share on other sites More sharing options...
