additional keys

I bought a 2004 Isuzu Ascender. It is the same as the Chevrolet TrailBlazer EXT, and GMC Envoy XL. My owner’s manual doesn't say how to program additional keys, but I know it can be done. PLEASE HELP!!

Best bet is to just call or stop back @ your dealership. If I knew how to do it, I would be happy to assist. I know I pointed out the obvious, but it's always the best bet.

Thanks.. Isuzu doen't have Passlock though.. dealer said it did and wanted to charge me an arm and a leg.. 415 dollars for 2 keys..

Are you trying to get keys or to program extra transmitters?

There is nothing special about the keys on my 2002 TB. In fact the dealer I bought from gave me an extra key, for free, when I thought I had lost one!

Programming an extra remote is not hard, I can post you the instructions if you need. $415 sounds more in line with this since the dealer wants $100+ for the transmitters AND labor for setting them up. Programming them only takes about five minutes.
