I've just got a Seat Ibiza, and while I was away workmen were given my spare key (without the remore functions) to move the car. Now the alarm goes off every time I start the ignition. I've tried every combination of remote buttons it seems, I've tried opening the car manually and turning the ignition within 15 seconds, but nothing stops the alarm sounding. The instruction manual and my Seat dealer were no help. Can anyone advise me how to start my car without the alarm sounding?
Many thanks
Mr S
