Old factory alarm on Concerto: disable?
 

Hi,
This is for a 1994 Concerto, RHD, UK. The handset has finally given
up(buttons damaged) and I don't have a spare. I am able to operate the
alarm by shorting out the contacts. Is there a manual override or
another way of disabling the alarm and, more importantly, the
immobiliser? The car is old, so it is not worth the cost of a new
handset. My e-mail is
