Ordering Spare Key

I would like to get a spare key for my Blazer. I understand it has a theft deterrent chip inside the key. Can I order a new key online or do I have to get it from a dealer? Would a locksmith be able to program the chip? I would like to be able to shop for the best price before walking into a dealership for a key. Thanks

Going to a dealer with your VIN is the only place I know of the get the keys with the chip in them made.

I had the spares for my 98 made at a local hardware store for $1 each. The security is built into the switch, not the key.

Was it the keys that look like this? I think thats what he is talking about, I could be wrong.

I didnt know they made the chips for the blazers...never saw them b4 eithier...worked in automotive for the past 4 years never saw one...but if u do have a chip i have to agree that the dealer with the vin is only place i know of.

If your keys look like the ones above, there isn't a chip in them.

I was confusing the Passlock system (which my vehicle has) with the Vats system, (which my vehicle doesn't have.) Thanks for the link Jeremy, my key is double sided and looks like the 16142. Thanks everyone for your reply's
