Problems programing keyless remote

these are the direction i got to program the remote but it dose not work because the hazzard lights dont flash. do you have any ideas for me.

Just get in your vech , close all doors. Using your power lock switch , lock all doors. After doors are locked take your Ignition Key and insert it and remove it from ignition switch in a slow fashion , but consitant pace. When you see the hazzard lights flash, put key in ignition switch and turn to the On postion .. Do NOT CRANK or you will have to Start over .. After in the On postion .. Hit the Lock button on remote... Hazzard lights should flash.. turn igntion switch off and unlock door and get out and try it. After you hit the Lock button on Remote and hazzard light flashed ..
