My key broke off inside my bike lock and various attempts to remove the fragment have failed. What are my options for having the lock cut off? It is a Kryptonite standard series d lock.

Grab the fragment with needlenose pliers and see if you can turn it
Assuming the metal part of the shackle is 12mm or less 42" bolt cutters should do it easily:
E.g.

A hacksaw and many blades will probably work but will take ages.
If you can get the lock on the floor (or something very solid - big stack of paving slabs or something) a cold chisel and big hammer might work.

I had something similar happen in Leith a while back. Called an emergency locksmith (unfortunately I can't remember which one). They showed up in a van, cut the shank with a power saw. Charged only £20.

I seem to remember that The Bike Station have helped out in the past with broken locks. Maybe worth giving them a call?

A worrying number of years ago i lost my keys in town and had to get the fire brigade to come and melt the lock off my bike with their oxy-acetylene blowtorch!
No idea if this is still an option but that made very short work of the same type of lock..Alternatively ive also heard D locks are susceptible to bottle jacks prising them apart.

Angle grinder. 5 minutes tops. I presume there are battery operated models these days?

What @crowriver said. Three minutes.

Is it an urban myth that you're meant to call the polis and inform them you're going to be angle grinding in this fashion?
I'd be inclined to do so just as a courtesy, but my mind is enquiring and that smells of urban myth.

I sense some kind of blind trial is in order.
In the interests of science. Obviously.

I seem to remember that @magnatom head some issues with a D lock after pedal on Parliament, and The Bike Station obliged with a battery powered angle grinder. A few minutes, and no awkward questions later, the bikes were free.
Possibly worth telling the police before you do such, but if you have some proof to convince meddling bystanders, then maybe not required

A year ago my key broke off outside the Armadillo after a Madness gig in the Hydro. I went back a few days later with pliers and a junior hacksaw. After trying to turn the stump of the key I gave up and used the hacksaw. Took 15-20 mins. The security guards at the Armadillo never said anything.

Someone from The Bike Station removed it with an angle grinder for £15 after I showed the bike was mine (I have the key to the rear frame-integrated lock). That was a bit cheaper than hiring one after including the cost of a suitable cutting disc. It took less than two minutes and made many pretty sparks.
Thanks for your input, everyone.
