Hey all.. hopefully a simple question for a bunch of car guys. I have several cars but my commuter is a 2003 Mitsu lancer. I changed the car battery recently and when I connected the negative terminal the factory alarm went off. The key fob will not turn off the alarm and I'm not sure what to do here. I've changed the battery before with no issues, but this time I can't turn it off or start the car. Anyone else experienced this problem and have an idea? Thanks..

yeah yeah ive got a similar problem with my 1994 CC and whenever i disconnect the battery the alarm goes off, and not long ago there was a short where i replaced a front right blanker (i have no splash guard on F-R side) and the car wouldnt start and when i attempted to, the alarm went off... i wanna take the ****in thing out and gonna hunt around on the net later to find if theres a DIY way to do it... if anyone, or OP knows how can u please let me know

What kind of alarm system you are using? Factory OEM or local dealer OEM or Aftermarket?
