Previous owner had car fitted with a professionally installed cobra alarm system which was working before l laid the car up a year ago. Now it doesnt seem to work (won't arm/disarm). Last week l had to disconnect the battery when l refitted the abs module which l had just had repaired. I can't see how could be linked and thought maybe the battery in the alarm remote had gone flat, but it's the same for both remotes and l think it would be unlikely that both batteries have gone at the same time? What should be my next course of action ie is there an ideal process of elimination to get to the bottom of it? Many thanks in advance.. Alan
