Please help me...I have a viper in my 94 ford exp......not sure of the model but it was put in when I bought the truck...it's been acting crazy.....put in new battery in remote & in truck....when i shut off truck doors don't unlock....if I try to unlock the doors from outside the truck i can hear a click but locks don't pop up.....if i'm driving & I try to unlock door by the unlock button nothing happens.....now today...the day after I have a new car battery installed things seem to be more normal but I'm so paranoid now I just want to rip the viper out altogether.....would this be a big deal?????

SOURCE: disable viper alarm

Yes the best way is disarm the alarm and put in a Valet Mode
To activate the Valet Mode do the following:

There is a push button or toggle switch to disable the alarm (to engage the valet mode). Without knowing where this
switch is you won't be able to disconnect the alarm.

1. Put the key in the ignition and turn it to the "on" position.
2. Flip the toggle or hold the push button for at least 5 seconds.
3. The LED. light will stay solid on.
4. Turn the ignition off
5. Release the push button. If you have a toggle leave it alone in step 2

This may be a problem with wiring. I will need to know what the make and model is of the car. Also keyless entry system stock OEM or was that an option you have added? Lastly, did you install this system or was this installed by a cetified DEI corperation?

Thank you,
Luis

Did you get help? My problem is similar but not as bad. My viper550ESP no longer remotely unlocks the doors (well very, very occasionally it does). That is the only problem.
