I have a Clifford immobilizer on my car and lastnight after I disarmed it my car went completely dead. I'm talking no power to ALL electrical devices. The immobilizer also never returned to its armed stage until this afternoon, but then did the exact same thing when I disarmed it and has been dead ever since. It almost seems as tho it's protecting against a hotwiring even tho I am using the computer key. I have no blown fuses and I have no experience with car electronics...someone help please
immobilizer killed my car

- Start date
I bought it lastyear with the immobilizer already installed so I have no idea who installed it, but up to now I've had no problems. The battery should be alright since I replaced it a couple months ago but I plan on checking that tonight. The battery was perfectly fine when I started the car a few hours before this happened also.
This may sound stupid but... have you check your battery terminals? More than a year ago, I had intermittent power failure problems. I'd put the key inthe ignition and turn the car "On" and everything would act fine until I tried to start the car. That killed everything. turned out to be crappy/corroded battery terminals and here I was overlooking the obvious.

The battery terminals were changed when I put in the new battery a couple months ago. Although I am starting to think it's a power issue that might not be related to the immobilzer. What else can cause a power loss like this. The first time this happened to me lastnight it was actually my dad starting the car and he said that it began to turn over and then everything died.
It's sounding more and more like a bad connection of some kind. Even new terminals can cause what you describe if the metals are disimilar enough to promote corrosion. My suggestion would be to remove and clean the terminals first (even if the look like they don't need it) then check your power and ground connections and wires to ensure that all is well. Removing and reinstalling those connections would be worth doing as well.
I would put a battery charger or jumper battery on it and see what it does. I like Andy's thinking - those immobilizers should not take out everything. A jumper battery can help, as can using jumper cables in parallel with stock cables, to narrow down a bad cable or connection.
Good luck.
