and an Oxford Disc Lock on the Front
both however proved little use when it was taken via the key's
I have since bought one of these "garage defenders"

not fitted it as of yet but will do soon,
now im toying with the idea of something like this as well as the defender....

Electronic entry via keypad outside the garage door, and a push button for the inside, electro magnet lock with holding force of 600lbs , cost is 150 quid?
not sure about getting it, might get it next month.
My garage has been broken into before ( new garage door since last time ) they got away with a Wacker that required 3 men to lift... it was a serious piece of kit, and a Disc cutter with a diamond cut blade that cost 250 quid! this was chained to the ceiling
What do you lot have, what would you recommend, have you thought about electro magnets?
