Thanks for the PDF!
I am trying to figure out which process to use, or more specially, if I need to use a "intelligent tester" to add a 2nd Key to the current master key. My 2nd key is LIKE the master key. Meaning it has a remote and they look alike. But they always refer to the master key as "THE" master key. So is there only 1 master key? And everything else is "additional"? I ask because the process for adding an "additional" key appears to require an "intelligent tester" or programmer of some kind.. Either way, I bought a $12 remote from Ebay and it's not working. When I use the manual method to add a 2nd master key, I insert the key into the ignition on the 5th time and then open and close the driver door 6 times, I put the new key in and the security light stayed on constant as it should, but then it immediately started flashing code 2-1. And that means the Code was not received. So I do not know why it is not received.. It doesn't say how to fix the issue. It just says "not received". So either there are too many keys already programmed, or I am using the wrong method, such as the manual method wont work, Or I can have only 1 master key... OR the Ebay remote is not sending the code... But it has a new battery in it.. So I have no idea what is wrong
