Why is my security lights on my 1994 olds cutlass supreme s after work was done

Even with 3 already put in? Could it be a wire that's loose in them? And if so why did Meninke didn't notice it?

YES in fact they did cut 2 blank keys using the same keys as the 1st one.If I have to get another chip how much will it cost

The dealership asked if I had another set of keys which I do cause the ones I gave him isn't working.Now if I give him the other set and it don't work what should be next?

Ok I see it,that's the blanks that they cut from the 1st time.Now if for some reason ,that blank don't fit,without the chip in it then they have to replace another one?if so how much will that be?

my car has a barcode inside could they just scan the barcode to find the right one,just curious?

Theose were the only 2 keys that I had when I brought my car back in 2004.With that said,will it be easier

Taken my other set of keys to the dealer and asked if this didn't what's the next step? Well found out that that key didn't work,so they have to order another set of keys from GM. Question? Since there aren't making Oldsmobiles any more will they have any issues in getting them and how much would it cost to get theose new keys reprogramed

well I just gotton my car back and it turns out that it was bad keys and everything worked out find.Thanks for listening and answering my questions.I've learned a lot from you guys;)
