Query: Works great, until you lose the remote

Had the DesignTech 23326 system in a Dodge Caravan since 1999. Finally lost the last remove 11/2012. Try to find a replacement... their phone line gives you the runaround for as long as you put up with it... "please call back during regular business hours..." uhm yeah this is Saturday 12:20pm, so you should be open according to your hours which you just recited... Many places sell such a remote transmitter [for $50 +shipping - not much less than the entire system cost]... but they claim the one that looks like our remote 23361 is not for our system 23326... different frequencies. Factory paperwork has nothing about the frequency, FCC number, or anything else that would HELP in getting the correct remote. At $50 a pop, we cannot afford to guess which remote is correct. So, great product, but ZERO USEFUL TECH SUPPORT. Cannot even speak to a person at all.
