Maybe this has been answered somewhere, I did look.

I'm trying to become more familiar with my car so I've been reading random parts of my Haynes manual. I've noticed that the directions for almost everything start with "disconnect the negative terminal of the battery." If I disconnect the battery will I need to have my alarm reporgrammed? or does it stay charged (or something) for a while? it is a Viper 800 HF alarm.

I'm asking because the one time I left my lights on for 8 hours and drained the car battery, I had to take my car in to get the alarm reprogrammed, and I had to go back 3 times for them to get it right. it was a pain.

Does anyone know?

 

It shouldnt but it might need to. HF is pretty old skool right?

 

Old school, huh? I THINK it was installed when the car was fairly new, like 1999 or 2000. Before it was my car.

 

Yeah, thats about right. Every year alarm systems are updated. Its so crazy and so hard to keep up with them, ie... how to reprogram remotes and reprogram options. Thats prob why they had problems with yours.
