Correct procedure for jumping flat battery

[Corolly Poly]

Just got back from 3 weeks away.

Car unlocked with remote and then died before I could start it.

Put noco GB40 across Battery and turned it on then alarm went off. I couldn't stop it.

After a lot of messing around with the charger and locking / unlocking with remote the alarm stopped and I was able to start the car.

I am thinking maybe unlocking with remote was a mistake and I should have done it with key to save what was left of Battery.

What is the best way to go about this avoiding alarms, etc when you are pretty sure the car will need jumping?

Thanks.

The only thing to avoid the alarm is do not arm it.

If you unlock with key, the alarm definitely sounds as soon as you open door. The alarm is only disarmed by the fob. So don't know what happened in your case, computer must have got confused.

From the manual, under "If the 12V Battery is discharged"...

Vehicles with an alarm  
(P.102): Confirm that the electronic key is being carried.
When connecting the jumper (or booster) cables, depending on the situation, the alarm may activate and doors  
locked. (P.104)

When the Green Flag guy did mine I'm pretty sure I unlocked with the fob, he connected his Battery booster and everything sprang into life and I could get to Ready mode. No problems with the alarm but you make a good point, ie what would you do if it was so flat you couldn't unlock with the fob and had to use the key?
