I had my automatic roller door serviced 4 years ago but it stopped working, again. I am very careful with it and only open it once or twice a week. I'm planning to forgo the regular costs of servicing/repairing a delicate and complex piece of machinery and use the manual overide instead.
I don't park inside my garage but do use it to store tools and materials.
My garage has an automatic roller door at the front and an older style manual roller door at the rear. Using the manual override on the front roller door I can lock it from the inside and leave the garage via the rear roller door (towards the backyard). Unfortunately I don't have a key for the rear roller door and so am unable to lock it. The locksmith has a callout fee and said that he cannot guarantee that it will be possible for him to make a key for the lock because it is an old/unconventional lock.
I was thinking to purchase a DIY lock if there is something I can install myself that might be able to attach to the external rear roller door and possibly something clamped/attached onto the concrete slab underneath it. Any ideas?
TIA
About what?
