Well the meta alarm I got is not one of the bigger names in aftermarket products like toad or clifford but there used by Audi, Merc, BMW, VW etc for alarm upgrades & such like!
It was the bloke downstairs that works for Audi got the number for me, they came to my work for the keys, went to my house where the car was 20 miles away, fitted the old system & installed the new alarm then brought the keys over to my work when they finished
