immobiliser problems only in retail park
 

just purchased a bug eye subaru wrx 2001 model it runs perfect drives like new and is everything you would expect from a subaru the only problem i have is when i park in falkirk retail park next to halfords , and dunelm mill the car wont start the immobiliser wont de activate when i return to the car if i park it at the other end of the retail park it will start no problem just wont start outside the shops mentioned and it doesnt do it anywhere else is there anything i could do to try stop this .........i was told it was interferance from the automatic doors from the shops someone also said it was interferance from the cameras but not all subarus were affected

Mate it's to do with telephone masts believe it or not affects all sigma alarms mine does it in tesco's Rotherham I had to push it round the car park once to get it to work. Lol flapped like **** till I phoned the dealer I bought it from and he laughed he knew were I was straight away so just try avoid parking there in future.

Does it still not de-activate when using the PIN on the keypad?
