Paid a visit to an excellent little garage near where I live to have a 'new' tyre fitted.
When I say new it was a Continental I bought with 7mm tread and no repairs - reason is, I'm fighting fast wear to the inside edge with tracking spot-on.
I need use of the car whilst I get around to fitting the new Lexus Lower control arm bushes - (garage will drift out old and refit new for a few £'s).
What greeted me was the lack of a key for removing the lock nut...there was me thinking it just had normal bolts.
So a few miles later and a day, I bought one from a Toyota dealer and eventually job done.
Luckily the pin number was on the original card in the boot. I know the previous owner who had the car and tyres fitted at the same Lexus dealership for 10 years...wonder where the original key went then.
As I did with my Jag, out came the lock nuts and in went standard nuts...there was a set of x4 new ones in the boot.
The nut key, a three pronged Z4676 cost me £24
That and the lock nuts and caps are posted in another place. See if I can at least recoup something.
Sometimes some things are complicated.
