What are the best solutions out there?
Thanks

drill holes through the door and into the surrounding brick work then use metal pegs to secure. simple and works.

I put a padlock through a hole in the door runner / rail so that the door only opens a small distance.

You obviously need to be to lock the door from the inside though.

Yep that’s what I was advised to do by the polis after my garage was done.
They said the scrotes expect to be able to peel the door up with a crow bar so you do the drilling quite low down so they can’t crawl under any space they can make

the problem is that the doors are actually pretty weak – a crowbar is enough to bend them enough to get in (though maybe not enough to easily get a bike out) so locking the runner doesn’t really help.

me too – and I’ve got metal shelf-rails jammed in each side at the botom stopping the swingarms from moving outwards

Park the car in front of it.

Brick it up and put something in there that’s fit for purpose..

Aristotle has the answer.
Access from both sides of the door rather than a padlock on the inside or a steel rod put into a hole, again, from the inside. The OP might not have any other door to the inside of the garage.

Jamie’s reply is a bit weak, does he really think if some scrote thats prepared to damage a door and steal a bike is going to worry about smashing a car window and letting the handbrake off. 🙄
