Source for replacement transponder ignition key blank

[Topbiker49]

Newb here looking for key blank. I just purchased a 94 Cutlass convert but it only has one ignition key. Does anyone know where I can get a key blank with the correct transponder chip? I have not been able to find a blank on ebay or anywhere else. If I have to go to a locksmith any idea of what it should cost. I have heard estimates all the way to $150.00.
Thanks

I got one off of ebay for about $10.

You need use a multimeter and put it on the ohms setting to determine the resistance. Then look at the chart that you will find in the ebay listing that tells you which number key to request.

Search ebay for "Cutlass Supreme VATS key".
