I have locking wheelnuts on the aluminium wheels on the pickup.I had the pickup serviced and MOT'd and six months later I needed some new tyres, locking wheelnuts sheared because of overtightening. I took it back to the garage who used a simple and easily obtained tool( or an angle grinder) to remove the locking nut and replaced with new set.
There are two reasons for telling this tale:-
1 They are not as secure as you might think though they would deter a casual thief
2 If you do have them fitted insist that correct torques are used and release and retorque at regular intervals, this is what I do as I have a suitable torque wrench but tyre fitters or mechanics may disagree, perhaps seek further advice on that one.
The important thing to remember is that they are not as robust as wheel nuts.
