Hi, i dont know which clifford alarm model i have :\ but here is the jist of it
The alarm stopped working all the sudden when i tried to arm it, it made a different beep noise.

-Click button on remote no response from car,

-Whatever, just go inside store and come out get in car no problems.. Go 2 gas station and get back into car after pumping gas alarm goes off, try to turn off with remote.. nothing happens.. put key in ignition.. nothing happens... eventually i just pop trunk and take out all fuses..car starts but alarm disconnected

-now when putting back the 25 fuse into the wires, the alarm goes off and the trunk pops open... then i take out fuse cuz i can't stand the noise...

-That is were my car is right now.. just no alarm.. no remote response from car? any ideas? Thanks in advance for ANY replys

 

Call the company or an alarm installer that deals with that type of alarm. Just ask them if they have had any problems like that before. Sounds like it might be shot and time for a new one. Do you have a backup battery? If so have you checked that? Did you change anything at all right before it stopped working?
