l have a 05 saab 9-3, l lost the key. What is the cheapest way to get a key made? if l get a key andcomputer from another car from a recycle/junk yard will that key work? or do l have to take it to dealer to reprogram it? If so does any one know who does that other then dealer in houston? Alland info will be highly appreciated

you can use a the key from the junk yard, but you have to get all the key cylinders the ignition and the anti-theft computer to use together, then you do not need to reprogram anything from the dealer

You will need a new CIM and a new transponder. Dealer only. Junk yard parts will not work since the Trionic and the CIM are encoded to each other. You are better off going to the dealer. The labor will be around 1.5 hours and the parts will cost about 300.00. Have them code you an extra transponder so that you have a spare.
