I was doing somthing in the trunk of my audi a4. I closed th etrunk with the keys inside and as you knwo the car locks itself. Is there a way to get into the car without calling a locksmith?

 

you can break one of the window glass. it's one of the way to get in.

dont tell me you only have 1 key.

 

I dont want to damage the car in any way shape or form. I heard that if you hollow out a tennis ball push it up against the lock tightly then blow into it the air pressure will open the lock. I dont knwo if this really works but if anybody knows any tricks besides breaking a window.

 

You don't need a locksmith but you'll need someone who knows how to get into a car without breaking anything. Typically, if you call AAA they will send someone out who knows how to do it. They'll have what looks like a wedge, in fact that's what it is. They will put that into the top of the door to pry it open a little bit and then he/she will snake a long stick looking thing in there to hit the unlock button.

That's how it worked for the two cars I've locked keys in. (2000 VW Jetta/2003 Nissan Xterra)

 

You should have a spare key. Give an Audi dealer your VIN
and they'll make a spare.

 

Rule 1: Always have a spare set of keys at home.
Rule 2: See rule 1
