"Specialising in automotive keys, A1 Locksmiths pride themselves on being one of the few Locksmiths in Perth who can provide Transponder and Electronic keys which many newer model vehicles use."
My father has been using these guys for years, great to deal with!
Note: When it comes to the replacement of vehicle keys we are obliged to go factory 'which we always have'. Regarding coding and cutting we have no hesitation recommending this service.
