Fitment will vary slightly depending on the internal design of your door - mine was a ribbed design so it would have been easier if it was flat!! if the galvanised plates over the runners are fixed to the wall, or the timber doorframe, like mine, then you can secure the door by fastening it to the galvanised plates.

Garage doors are particularly common targets for burglars. This not only puts the valuables in your garage at risk of theft but may also provide a point of access to the entire house. Versatility: Different sizes and designs to fit any type of garage door. An Enfield bolt will fit your needs. However, Enfield garage door bolts may not fit all types of garage doors. Some may need changes or extra parts for proper installation. So, it’s important to consult a professional or read the manufacturer’s guidelines before buying these bolts. Stylish: In addition to their practicality, these bolts add a touch of elegance to your garage door.You just need to drill a couple of holes into the ground using a 16mm drill bit. Because you’ll be drilling into hard concrete, use an SDS drill. In my case i screwed the bolts onto the framework (skeleton) of the door and drilled up into the lintel and down into the concrete floor, which might have been easier. I gather from your pic that you have a latch operated by a steel wire from the handle. By drilling a hole in the door, a burglar poke or pull this wire and the door will open. it might also be possible to fabricate a tool to hook the wire, poked through the gap at the top of the door.

You also get a set of 5 keys that can be used on both the inside and outside. What we like about it:
