The locking wheel nut is a anit-theft device fitted to most vehicles with alloy wheels. Each vehicle manufacturer will have many combinations.
The lock nuts are removed with a wheel brace and NEVER an impact air gun at GT Tyres, then re-fitted with the brace and torqued correctly.
Sometimes lock nut keys are missing, worn or even damaged, we can remove some of these for a fee.
All locking wheel nut keys are returned to the customer in person after we have carried out any work which may involve the wheels being removed from the vehicle, this removes the confusion and any blame on either side to where it was returned to.
