I had an aftermarket remote start installed on my old Tahoe. The valet button was just zip tied under the dash. Find the starter box and check to see if one is zipped up somewhere. It was only a momentary button with two wires. If you can't find one look to see where it would connect and make one.

 

Thanks Copper, I found the starter box....wayyy up under the dash, and no valet switch. I've taken the reset switch complete with the two prong connector out of an old computer tower and tomorrow morning I'm going to give it a shot. Hopefully it works !

 

So...I have been banging my head off the wall trying to figure out where my "valet switch" may be located...IF...I even have one !

Most systems the valet switch is located in the driver underdash or kick panel. On newer systems most of the manufacturers are incorporating the switch into the antenna which is normally mounted on the windshield. Depending on who installed your system you may or may not have the switch at all. It isn't uncommon for them to not be installed as many systems we program using a programmer versus the switch and also we generally don't want the end user to be messing with the switch. Most systems once you enter programming mode hitting the wrong button can set all options back to default.

Also are you saying your trying to program a remote from a different system/manufacturer? Remotes are very specific to what they will work on and unless the FCC id on the remotes you have now matches the ones your trying to program the chances of it working are slim to none. Anytime you go for a new remote you want to make sure you get one that looks the same and has the same FCC id / part number. Hope it helps,

The remote I am trying to program is not identical but does look very similar to the one from the original manufacturer. The FCC/Part numbers match exactly. I managed to find the instructions on how to program a remote for an AUTOSTART brand remote starter and it turns out it does not require the valet switch. You simply flash the hood pin and within 20 seconds turn the ignition on and off once then hold the lock button on the new remote until your parking lights flash five times and it is programmed, I know this works for my system because I tested it with the original remote and it works exactly how it is supposed to. However I cannot get it to work with the other remote with identical numbers..... I'm baffled ...
