Locked myself out of my truck...

A family owned hardware store that made copies. I handed them my truck keys and asked for a copy without the chip inside. Cost about under $2 if I can remember. I'm pretty sure Lowes or come depot can do the same

 

I see. I have basic truck that doesn't have chip key.

 

This won't work on second gens

 

But if you could get a long enough string through like that, then use it to pull the door open enough to put a coat hanger through and hit the unlock button
