If you use the viper remote to arm the alarm, you MUST use the viper remote to disarm the alrm prior to opening the door. The only REAL solution is to add the keyless entry feature to the viper system, and quit using hte factory remote all together.

Your alarm got put into valet mode some how
.It's easy to reverse out of it back to normal. First look for a small black push button under the dash somewhere. It's called a valet button. Here are the steps.
1. open door
2.turn key on then off
3.then within 10 seconds hit that valet button once(your alarm light should be off. Tell you arm it again. Then it will blink)
Hope this helps
