Puncture at South Mimms and the locking nut key is nowhere? We remove the locking nut without harming the alloy, then fit plain nuts and put the tyre right before leaving.
Hertfordshire drivers who have never needed the locking key often find it missing when a tyre goes down on the A1(M): lost in a house move, left in a previous car, or absent from a used car bought in Stevenage. Some still own the key, only to discover the nut rounded after an impact gun at a past tyre change, or snap the key trying to force it at Baldock services.
Put the wheel brace down before the alloy gets marked. We carry removal kits for the common locking nut patterns, including the free-spinning outer ring type, and take the nut off without chewing the wheel's finish. Standard nuts replace it, then the flat is fixed or a new tyre fitted while we are there. The removal and the tyre work are quoted together before we leave NW2.
Other jobs we do at the car include emergency tyre repair on the A1(M) and new tyres fitted on the A1(M).
Your drive, a Letchworth or Hitchin street, Stevenage station, the Galleria car park, or the car sections at South Mimms and Baldock services. The nut is never tackled on the A1(M) itself or in the Hatfield Tunnel.

At the London end, a missing locking key can turn up as a problem in Barnet. A space near High Barnet station, a road off Barnet Hill on the A1000, or a home around Hadley Green are all reasonable places to meet. Specialist kit takes the locking nut off, any tyre work follows, and we suggest fitting new locking nuts.
A missing key may be in the spare-wheel well, a tray under the boot floor or the glovebox, sometimes bagged with the jack. Keep hold of any key code card, since the maker's code on it lets a replacement be ordered. The logbook or other proof of ownership may be requested before we start at the Galleria. Protection goes over the alloy's face during extraction, and fitting a fresh locking set afterwards is worth considering. Hatfield town centre bays off J4 of the A1(M) suit the job too.
