Commando RS-560 with Remote Start Problem

I have a 97 Voyager with the RS-560 installed. My problem is I cannot get into the remote start programming to set the Tach. I can program the remotes(Turn key on/off 3 times an stay in On)with no problem. I cannot get into remote start programming ((Turn key on/off 3 times an stay in off position then push the valet 10 times). Has anybody had similar problems or any solutions.

Thanks Doug

Is your siren connected?  It is very difficult to enter programming without it installed.  Also, the button you have to press is very difficult to use as you likely have realized.  Since you need to press the button 10 times your odds of messing up are greater than when entering transmiteer programming.  Try using a pointed object and make sure you press the button very deliberately and release it completely between each press.  Also, make sure that you hold the button down ON the 10th press.   Keep trying until you get it.  I always have trouble with those because I have big fingers. 

Good Luck
