Extra security for up and over garage door

[Snake Plissken]

Want to add extra lock or security to a garage door. Its quite standard up and under metal door (aluminium?) with a central lock. Anyone suggest which way to go ? Can see there are the type that bolt into the floor in front of the door to stop it opening, don't have a power outlet near the garage so would have to rely on a cordless drill to fit.

Just took a photo of what I did to my door, hole in concrete drilled with a McAllister cheapo Screwfix cordless drill, straps made of bent ally and bolt bent tube.

Obviously you can beef this up as much as you want but it holds the bottom of the door fine as it is.

Just wire it into the mains so that any scroat trying to break in is fried.

Mine isn't attached to the property so I need to be able to open it from outside the garage door (unless I'm seeing yours wrong)

Yep, only way in is from inside as I disconnected the handle as well.

I've seen some with a simple hasp and padlock arrangement attached at the top of the door, just rivetted on or screwed on with a bolt and nut. Could be attached no bother with a battery drill, I'd be rounding off the screw heads on the bolts though. 

Best would be some sort of attachment to the bottom of the door, into the concrete in the ground, probably do-able with a battery drill too.

I'm no expert though.
