Do you keep your locking nut in the car?

[Penfold101]

Don't have my locking bolts on the car - they're not worth the hassle if one won't come off even if you do have the locking nut...

yep mines in the car too

Mine lives in the car, same as Sharon's.

Absolutley pointless not taking it with you.

Providing you keep the locking bolt in a sensible location within the car then if someone does break into the car they are more likely to steal more than just the bolt!
