Hi,

Is it possible to disable keyless entry on the IS220d? I'm not using my car everyday at the moment and it's started struggling to start when I do get back in. It seems the Battery is getting drained which I'm presuming is down to the keyless entry system. I had no problems with starting prior to parking it up. I've looked through a manual I've found online but there's no mention of disabling it.

Thanks.

Are you sure it isn't just the Battery on its way out? The keyless entry system doesn't use that much power - there is a way to disable it on newer vehicles but not sure about the series II IS - if you can it would be via OBD software rather than a menu option (Carista etc.).

I am not aware there is a way to disable it, but as mentioned above it is very unlikely to cause start problems. Diesel especially needs high current to start, so most likely you need to check you Battery voltage etc. Same happened to me in the past - if you lucky enough to start the engine car will run smoothly. 

One tip, press start stop button without pressing the brake (not sure if that is how it works on manual) so that all electrical bits can start first e.g. mirrors opens up, steering wheel moves to position etc. And only then press brake/start button to start the car. What I noticed, when you have Battery on the way out it usually doesn't have enough power to do everything at once and then fails to start engine. Sometimes you only have 1 shot to start and so better not to waste it.

Second tip, try to turn off as much possible electrical systems before you turn off the engine e.g. heated seats (particularly), radio, climate control, auto-headlights. When you come to start it then, you pretty much only starting the engine and it requires less power to start. I don't think there is a way to turn off auto tilting steering wheel if you have one fitted, but then follow what I said in tip 1.

Sorry for the delay. Thanks for the replies guys. I suppose there is always a chance the Battery is on the way out.

 

Thanks.
