Now here's a thing.
Ever since I've had the car the rear boot lock (where the key goes in) has been seized solid, another thing the RAC 'comprehensive' inspection missed >:( ::)

Having had several cars do this to me before with all the cr*p on the roads up here and bearing in mind it does have remote central locking etc it's not really a huge problem.
But the 'perfectionist' in me wants it fixed....... and it won't 'unseize' either :'(

Presumably I'd have to go to Fiat for a replacement lock that would fit the vehicle or would I (as I suspect) be looking at a completely new set of locks all round...... ???

I think you may be able to get a new barrel for the lock ..would give fiat a call to confirm that tho :-\
