As a vehicle tech for the agnew group I believe on a way to reduce the amount of time spent on each vehicle is to ask the customer to have their locking wheel nut key either in the spare wheel kit or somewhere that is easy to gain access. It can become quiet frustrating when you've to spend a percentage of the time allowed for each job, trying to find a locking wheel nut. Most times they're either not in the proper location or the boot is too full to gain access into the spare wheel, which means spending more time searching or removing products. Hopefully this helps on reducing the downtime spent on repairing vehicles in the future.
