With all the car thefts on here recently its got me seriously thinking about upgrading the security of my garage.

What can you do to upgrade garage security??

In my eyes garages hide the car from prying eyes but also hide crooks once they are inside and doors down to a night of unrestricted access to your motor.

Also theres a fine balance between too much security meaning you become a target on the grounds of "you must have something worth nicking" to having too little and being vulnerable.

So what security devices can you add to your garage??? and the car when in the garage??

Im thinking theres several areas to cover:
The door
Preventing removal of car once they get past the door.
Alarm systems.
Additional car immobilisation especially for a garage. (im thinking removing essential componants on top of usual car security).

Ultimately i realise you wont stop the professionals as they will just enter the house and rob you at gun point for the keys from your bedside but its the chavs and opportinists i want to stop.

Any ideas??
