Hello and welcome to JA!!!

I'm Billy and i will try to assist you with this.

As for as i know, in your model, when the alarm activates the flashers will flash once, and they will flash twice when the alarm is deactivated......please confirm if true.

One more thing: is the remote locking/unlocking still operational, or do you have to manually lock/unlock the door?

Get back to me on these......and hopefully we will sort this out......

Regards

Billy

In that case, you need to check for any blown fuses............causing the alarma system to be deactivated.

If no blown fuses are found.........then you may take off the battery cable for a few minutes to reset the systems.......and the alarm system should work.......

If not, then you need to have the car scanned, in order to figure out, if the alarm module is faulty......or just needs activation (on scan tool).

Regards,

Billy
