Australian Car Repair Issues? Ask an Auto Mechanic for Answers ASAP
For you the easiest way is to form a hook from the coathanger wire to lift the drivers door snib button straight up.
You need to be able to hold the top of the door frame out a fraction with a screwdriver etc, for the coat hanger shape to reach the door knob.
Failing that, you will need somebody to help you that has done this before.
I done this many times on many cars at work.
How far away is the spare key? And can you get someone to get it?
Were you able to get into your car?
I hope my advice has been of assistance to you.
