The worst version of this problem is not a lost key, it is a broken one. Factory keys are often a slim hardened insert inside a thin sleeve, and when somebody puts real force through them the insert can shear off and stay wedged inside the nut. Now there is a piece of hardened steel filling the recess, and nothing else can get near the nut until it comes out. A replacement key will not go on. An extraction socket has nowhere to sit.
So it becomes a two-stage job. The fragment has to be drawn out first, carefully, because it is harder than the nut around it and hammering at it will simply spread the nut and make everything worse. Once the recess is clear the nut itself is usually straightforward. It is more work than a plain seized nut and it is entirely recoverable, which is worth knowing before anybody starts talking about recovery trucks.
You do not think about the locking nut until the moment it stops you. We carry specialist removal kits for exactly that and extract the nut where the car is standing, on a driveway in Bowes Park or on Lordship Lane, with the alloy protected while we work. The wheel comes off in Turnpike Lane, not on a ramp in Tottenham. Nothing is towed out of Bowes Park or Alexandra Palace; the work finishes there.

Wood Green is not a place to leave a car sitting while somebody sorts out a garage, with the High Road congested most of the day and kerbside space short around Noel Park and the residential streets. Because this is a tools job rather than a workshop job, it happens where the car already is, and the tyre work carries straight on in the same visit.
Harder than the nut around it and firmly wedged. It has to come out before anything else is possible, and it will not respond to force applied at random.
Because there is already something in the hole. People order a replacement key, wait a week and then discover the recess was never empty.
Multi-storey and surface car parks are fine to work in provided there is clearance for the van. Nothing has to be driven anywhere first.
Yes, though it is a two-stage job. The fragment comes out first, then the nut. It is more work than a straightforward seizure and it is not a lost cause.
Not until the old one is out. A new key cannot go into a recess that is already occupied, and you will have waited a week to find that out.
Not if the fragment is drawn out rather than driven in. Hammering at hardened steel inside a nut is what spreads the nut and marks the wheel.
Longer than a simple removal, and still a single visit. There are no parts to order and the car does not move.
A plain nut matched for thread and seat, torqued to your manufacturer's published figure, and we can replace the whole set if you would rather.
