Damn! Still no go! I am going to the dealer where the original owner always had it serviced. I got in good with the parts guy a few weeks ago, so I'll see if they'll help me out on this.
I am still thinking I got scammed and was sold a bad remote on eBay.
The eBay seller stated that he had a new alarm installed with power loks etc. in his G20 and that is why he is selling the remote. Now I am wondering if the only thing wrong with his factory alarm is the remote was bad and he figured it was the alarm.
