TFR,
whoa! hanep pala yang VIper 900 16 channels!

mukhang mahirap nga bumili dito nyan locally. your best bet is to order a remote sa US. meron ako nakita website noon selling those remotes. If you have a relative in the US paorder ka sa kanila para mas mabilis.

For a temporary fix ...para magamit mo pa rin you can buy the 2 button 3 channel remote ng Viper. sayang nga lang di magamit yung ibang features.
