My store door is too thick approx. 3′ inch and it uses European style locking mechanism, Handles always breaking, We’re in old port of montreal, What could i do ?

If your door uses European style locking mechanism we could help you most of the time by converting your door to use standardize deadbolt we have varaity of locks that could fit 3” inch thickness and will work smoothly, solve your issue of replacing a new door which could cost thousands of dollards and city permission to install it. see the European style door in montreal downtown OLD PORT VIEUX PORT montreal, in cote-des-nieges CDN, Notre-dame-de-grace NDG, Ville st-laurent VSL, Westmount, Outremont, most city where old doors are still operating. we just did, we have made a few modification for lock to fit and it works out great.
