Unlock Car with Dead Battery

[Stan]

The positive terminal on the starter motor goes directly to battery positive - so if you put a charger o or jumper on that and earthed on the chassis somewhere you could charge or jumpstart the car

Glad you got it sorted

Or in your case at least unlock the doors via the remote

Glad to hear it's all sorted though, although I would be looking at replacing that battery as they don't like to be discharged all the way down. That and I wouldn't have thought that your diagnostic thing would draw so much power as to completely drain the battery.

Plan B: Invest in a hard mounted battery charger in the garage to use when you go away for longer periods to ensure your battery is always kept topped up

Glad you didn't have to resort to this.....

I couldn't see the door unlock due to my dark tint and the poor light in my garage on Sunday night.

well, there's your problem. i had my battery suddenly die on me before, so i was pretty sure the insert-key-in-barrel would work.

kaanage, I didn't understand what would be achieved by being able to do this, but now that I am in it does not matter anymore.

The starter motor is directly connected to the battery so you can connect a charger from underneath the car when you can't open it.

If its( the starter) not buried, but in the BJX it most certainly isnt. Sean Battery a bit dear mate but you caught out with it, batteries have a knack for this.
