Disconnect ground and remove key?

[davej_anderson]

Reading some of the TSBs and the workshop manuals, I noticed that some instructions tell you to remove the negative connector on the battery and then to remove the key e.g. removing the door.

Surely this will cause the alarm to go off as I thought you had to leave the key in the ignition turned to position II when removing the battery to stop the alarm going off.

Any insights or thoughts as to why Porsche would tell their staff to do this?

Or am I wrong and you can remove the key once the battery has been removed?

I removed the neg from the battery when I replaced my air bag frame. Don't recall the alarm going off for that!

Did you leave the key in the ignition?

RoW alarms are different than US/Canada alarms. Where are you located davej_anderson?

He is from London. Most of the UK cars have an additional siren for the alarm. This siren has a built-in battery. If you disconnect the car battery without first turning the ignition key on, then the siren goes off. They say it is very loud....

Yep I'm from London and yep, its very loud as I've found out in the past! And it takes a while to reconnect and get the jey back in the ignition making me popular with the neighbours.

The only reason I asked was due to the warning about working near the airbag which I will be doing when adding speakers to my door.

Looks like I just have to go with key in the ignition and the battery disconnected.

For ROW Europe cars, the best you can do is: turn the key in poss. 2 ( warning lights on the dash on )

disconnect the neg. from the battery

once the battery is disconnected you can do with the key what you want

before you reconnect the battery reinsert the key in poss. 2

Ill see if removing the key does anything

Thanks for your help
