2014 Lexus 300h Won’t Start after 6 weeks idle

[Brightfox99]

Left car idle while on vacation 6 weeks. Won’t start. Pushing POWER button only shows “POWER ON” on main screen but nothing happens. Can’t get into trunk to charge Battery as no power to open it. Any advice appreciated much.

Apologies if you’ve already tried this - or I’ve completely misunderstood you - but you should be able to remove the mechanical key from the electronic case and use it to unlock the boot lid.

You don’t say which 300h it is, but the key lock should be located under the lip of the boot lid.

Just wondering how you got into the car if there was no power to open the boot (trunk)?  Incidentally, it may be worth changing the key Battery if it’s not been done before.

I hope this helps!

You are depressing the brake pedal when pressing the Power button?

If you cannot get to the boot then you could always try the under bonnet charge/jump start connections and as shown in this video.

Your manual will more precisely show where the connections are situated
