| hi mate,
we have a steering lock which is used requently. I tried to find it on the halfords webpage but couldnt find it.
Its halfords own, like the disclock one, only it covers half the steering wheel with a bar coming out of the bottom. has the same issues with the lock as you mention, but you do get used to it -- i.e. return the key to the open position befoe removing the key. if the barrels are out of alignment wriggling the key gets them back aligned easily. |
