Key won't go into ignition or turn

[Solitude]

I bought those keys on ebay.. went to the locksmith down the street to get them cut.. he had 5 hanging on the wall..they arent oem..they just look oem.. black and all..but no isuzu emblem inside.. but for 5 bux.. I dont feel like I got robbed.. just tickled a bit

Ebay's where I got mine probably got them from the same Ebay dude but they work.
