We can attach "Fred" the lockbox to a permanent fixture near where your car is parked - for example a fence, gate or front window bars.
Alternatively, the lockbox can be attached to the car by a small metal bracket that flips over the top of your rear driver's side window. You just wind the window up and the lockbox sits there snugly.
The borrowers are instructed to take it off and put it on the back seat when they're driving, and just pop it back on with the key inside when they finish up.
Fred will not damage your car. If your windows are tinted, we will provide some rubber backing for the bracket to avoid any potential scratching.
