Compustar CS4900-S Remote Starter

They are not both 2 way. The silver is 2-way and the black is 1-way. So since you keep trying that way without success. Try it using the double button (trunk+key) hold to scroll through the steps using the 1-way black button remote. Do it just like in the video.Steve G

I just installed one of these and also having a hard time programming this remote start. The book says press lock and unlock for 3 seconds and do it again for 3 seconds. Then I tap the key button and wait for the light to flash, do it again for option 2, do it again for option 3 and it wont let me do it again, it doesn't do anything. I don't get what im doing wrong. Ive been trying for the longest .

So I was able to finally get it to work. I had to use the one way remote to get to the options menu, the two way remote didnt work at all. Hopefully it will work for u too.

I am having the same issue with my CM-900. Any luck on a fix? To go into option menu 2 I follow the instructions as such: Lock + Unlock for 3 seconds, then Lock + Key for 3 seconds. Then I tap the Key to scroll through the menu, but after 3 taps and confirming blinks on the truck it will immediately flash 3 times and exit the menu. Why? Its driving me crazy!

What color are the buttons on the remote you are trying to use for programming?Steve G

Silver Buttons

Alright everyone! I wanted to report back and let everyone know the fix for this problem. Short answer is the instructions are wrong for the 2 way remote programming. I have two way remotes, but without the LCD screen, and not matter what if I followed the instructions for the 2 way 4 button remote chart it wouldnt work. I used the instructions for the 1 way 4 button remote and it worked perfectly. To scroll through the menu, you have to push Trunk + Key for 3 seconds until the lights flash, and keep doing that until you reach the desired menu, for example menu 10. Then it will flash at you 10 times to confirm that its in menu 10. Then you would push whatever Function Option you want after that and then it will confirm what you pushed by flashing back. Anyways just wanted to let everyone know, just use the chart for the 1 way remotes and you will be set. I am thinking that if your remote doesnt have the screen then use the 1 way remote chart. If your remote has the LCD screen then the 2 way remote might work? I dont know for sure. Hope this helps someone!

Thank you for this!!!

@walkbyfaith ...you are a lifesaver lol. It worked perfectly for me! I almost ordered that op500 options programmer and happened to see your post. What gets me is why firstech/compustar are still handing out units with clearly the wrong info/instructions. I emailed them for help and their reply was "unfortunately your problem is one that can only be diagnosed by an authorized dealer" noooo....its your wrong instructions to program a unit YOU SELL!😅😆 Oh well, all is great now thanks to you. Much appreciatedIf it is to be..it is up to me
